Social Security is the most popular legacy of Franklin Roosevelt's New Deal. Last year almost 60 million Americans received benefits from the program. Payments amounted to over $875 billion, nearly a quarter of all federal spending.  For more than two decades, most discussion of Social Security, at least in Washington, has centered on its funding shortfall. Contributions to the program are not high enough to pay for all benefits scheduled under current law. The Social Security Trust Fund is expected to be depleted around 2030. If Congress does not address the funding problem before reserves are exhausted, monthly payments will have to be cut about one-fifth.

Despite the projected shortfall, Democrats in Congress have begun to argue that Social Security benefits should be expanded rather than cut.  Senators Bernie Sanders and Brian Schatz have offered proposals to boost monthly pensions while at the same time shoring up Social Security finances through tax hikes on high-income Americans. 

That Democratic voters and lawmakers embrace these ideas is not surprising. But opinion polling suggests such reforms also enjoy broad support among self-identified independents and Republicans. For example, 57 percent of Republicans (versus 71 percent of Democrats) favor increasing cost-of-living adjustments in the benefit formula. Forty-eight percent of Republicans (versus 67 percent of Democrats) favor boosting the minimum benefit available to low-wage workers who have contributed for many years to the program.  Seventy-four percent of Republicans (versus 88 percent of Democrats) favor raising taxes in order to protect benefits. These polling numbers were obtained in 2013, but more recent polls show similar opinions. Even if debates among Washington insiders and GOP lawmakers focus on how to trim benefits in order to keep Social Security solvent, poll results suggest Senator Sanders holds views closer to those of the typical voter.

One question for both voters and policymakers is whether the aged population is really the most deserving target for additional government spending.  Much of the discussion of voter disaffection in the current election cycle has focused on the stagnation of middle class incomes and the rise in inequality.  While these represent major problems for families headed by a working-age person, they have not been notably troublesome for the nation’s elderly.  The incomes of the elderly, unlike those of the nonelderly, have increased steadily over the past three or four decades.  For low- and middle-income retirees, incomes have clearly improved. The same cannot be said for the incomes of low- and middle-income working-age families. Income inequality among the elderly has increased, to be sure, but much more slowly than among working-age families.

In new research with my colleagues Barry Bosworth and Kan Zhang, I have examined trends in real incomes and inequality among the nation’s elderly and compared them with the same trends in working-age families. We show that inequality has increased among both the elderly and nonelderly, but it has increased much faster among families headed by prime-age and younger adults than among families headed by someone past age 62.  More to the point, real money incomes have increased much faster among middle- and low-income aged families compared with middle- and low-income working-age families. 

Our estimates of the annual rate of change in real money income are displayed in the chart below. The changes are estimated over the period from 1979 to 2012 based on data reported in the Census Bureau’s annual income survey. The top panel shows changes in families with a head who is less than 62. The bottom panel shows changes in families with a head older than 62.  Each bar shows the annual rate of change in real income at the indicated position of the income distribution, either for nonaged families (in the top panel) or for aged families (in the bottom panel).  At the top of the two income distributions—that is, at the 98^th income percentile—real income gains are virtually the same in the two groups.  Further down the income ladder, the income gains differ noticeably, with bigger differences the further down we go.  Middle- and low-income working-age families have clearly fared much worse than families with an equivalent position in the old-age income distribution.

Estimates of income growth based solely on pre-tax cash incomes, such as the ones in the chart, almost certainly understate the improvement families have seen in their living standards, as I have argued elsewhere (here and here).  However, the understatement is bigger in the case of elderly and low-income Americans than it is for the nonelderly and affluent.  If we adjust family incomes to reflect the taxes families owe and the monetary value of their noncash benefits, the relative improvement in the standard of living of older Americans is even greater than is shown in the chart. Under almost any plausible income definition, the elderly have fared better than the nonelderly, especially at the bottom of the income distribution.

The income statistics do not prove the policy reforms urged by Congressional Democrats are unneeded or undesirable. Their proposals spring from an accurate reading of a long-term trend toward less pension coverage — ironically, a trend that has mainly affected working-age adults.  Whereas workers in the 1950s through the 1970s enjoyed continuous improvement in their access to employer-provided retirement benefits, the improvement ceased after 1980. Since that time, private-sector workers have seen reductions in the coverage and generosity of their employer-sponsored pensions. If the private sector voluntarily provides less retirement protection, it does not seem unreasonable to expect the government to provide more.

A crucial reason the nation’s elderly population fared better compared with the nonelderly after 1980 is that Social Security and Medicare provided them government protection that was far more generous (and more costly to taxpayers) than the protection available to working-age adults and their youngsters. The gap was especially glaring in the case of families headed by low-wage breadwinners, who have suffered sizeable reductions in pay and employment opportunities. In the years since 1980, their losses have been only modestly compensated through changes in the tax code and expansions of public health insurance.

Changes in the labor market make it important to protect future retirement benefits provided through Social Security. The same labor market developments make it even more urgent to expand the employment opportunities and improve the protections and work supports offered to working-age breadwinners.  In 2016, the weakening of future income protection for the aged is mostly theoretical. In contrast, the sinking fortunes of less skilled working-age adults are anything but theoretical. They are plain to anyone who can read Census and Bureau of Labor Statistics reports. If taxpayers can identify additional resources to pay for major new initiatives, my vote is for programs that improve the prospects of struggling wage earners. The equity arguments for such an initiative seem to me more persuasive than the case for an across-the-board benefit hike targeted on retirees.

Unlike prime-age Americans, who have experienced declines in employment and labor force participation since the onset of the Great Recession, Americans past 60 have seen their employment and labor force participation rates increase.

In order to understand the contrasting labor force developments among the old, on the one hand, and the prime-aged, on the other, this paper develops and analyzes a new data file containing information on monthly labor force changes of adults interviewed in the Current Population Survey (CPS).

The paper documents notable differences among age groups with respect to the changes in labor force transition rates that have occurred over the past two decades. What is crucial for understanding the surprising strength of old-age labor force participation and employment are changes in labor force transition probabilities within and across age groups. The paper identifies several shifts that help account for the increase in old-age employment and labor force participation:

• Like workers in all age groups, workers in older groups saw a surge in monthly transitions from employment to unemployment in the Great Recession.
• Unlike workers in prime-age and younger groups, however, older workers also saw a sizeable decline in exits to nonparticipation during and after the recession. While the surge in exits from employment to unemployment tended to reduce the employment rates of all age groups, the drop in employment exits to nonparticipation among the aged tended to hold up labor force participation rates and employment rates among the elderly compared with the nonelderly. Among the elderly, but not the nonelderly, the exit rate from employment into nonparticipation fell more than the exit rate from employment into unemployment increased.
• The Great Recession and slow recovery from that recession made it harder for the unemployed to transition into employment. Exit rates from unemployment into employment fell sharply in all age groups, old and young.
• In contrast to unemployed workers in younger age groups, the unemployed in the oldest age groups also saw a drop in their exits to nonparticipation. Compared with the nonaged, this tended to help maintain the labor force participation rates of the old.
• Flows from out-of-the-labor-force status into employment have declined for most age groups, but they have declined the least or have actually increased modestly among older nonparticipants.

Some of the favorable trends seen in older age groups are likely to be explained, in part, by the substantial improvement in older Americans’ educational attainment. Better educated older people tend to have lower monthly flows from employment into unemployment and nonparticipation, and they have higher monthly flows from nonparticipant status into employment compared with less educated workers.

The policy implications of the paper are:

• A serious recession inflicts severe and immediate harm on workers and potential workers in all age groups, in the form of layoffs and depressed prospects for finding work.
• Unlike younger age groups, however, workers in older groups have high rates of voluntary exit from employment and the workforce, even when labor markets are strong. Consequently, reduced rates of voluntary exit from employment and the labor force can have an outsize impact on their employment and participation rates.
• The aged, as a whole, can therefore experience rising employment and participation rates even as a minority of aged workers suffer severe harm as a result of permanent job loss at an unexpectedly early age and exceptional difficulty finding a new job.
• Between 2001 and 2015, the old-age employment and participation rates rose, apparently signaling that older workers did not suffer severe harm in the Great Recession.
• Analysis of the gross flow data suggests, however, that the apparent improvements were the combined result of continued declines in age-specific voluntary exit rates, mostly from the ranks of the employed, and worsening reemployment rates among the unemployed. The older workers who suffered involuntary layoffs were more numerous than before the Great Recession, and they found it much harder to get reemployed than laid off workers in years before 2008. The turnover data show that it has proved much harder for these workers to recover from the loss of their late-career job loss.

The support for Bernie Sanders among young people has stirred a debate about the merits of the American style of a market economy versus the European version, and particularly the Nordic version of capitalism seen in Denmark.

Of course, the chances that Sanders will actually become president are remote and the chances of his enacting his program, if he were to become president, are even more remote. Still, the debate is an interesting one. David Brooks (writing in his New York Times column February 12, 2016) says that Denmark and similar economies in Europe are stagnant and lack the dynamism of America. Sanders’ supporters wrote in response, pointing to the strengths of Denmark: the absence of extreme poverty, the guaranty of good quality health care, and the availability of free college education.

Denmark gets a lot of things right. It provides universal health care of high quality at only a fraction of the cost of the U.S. system. Health outcomes are at least as good as in the United States with Danish wait-times similar to those we have here and infant mortality much lower. Denmark also does well in its primary and secondary education and in its labor market programs. They use tough love on those who are out of work, providing generous income support and training, but if they do not find a job or accept one that is found for them, the unemployed lose their benefits. The Danish “flexicurity” system is much admired because it combines a flexible labor market with income security. People are not guaranteed to keep the job they are in, but they are pretty much guaranteed that they can have a job.

Brooks is correct in pointing to the negative impact of very high tax rates on work. In the Nordic economies and in Germany, the employment rate is high but people work a lot fewer hours than workers in the U.S. On average, employed workers work 1,788 hours a year in the U.S. and only 1,438 in Denmark, and even less in Germany at 1,363, according to the OECD. Of course the Europeans are choosing to work shorter hours, but that choice is made in the face of very high taxes. Consider a busy professional couple in Denmark who want a renovation done to their home. They take home only a fraction of their salary after paying taxes and then they pay a plumber or an electrician to work on their house, and each of these tradespeople gets to keep only a fraction of what they charge for their services. The couple may find it is better to forget about the renovation, or hire people off the books to avoid the prohibitive double taxation.

In terms of innovation, Europe does not have the equivalent of Silicon Valley or the innovation hubs around Cambridge, Massachusetts, or the National Institutes of Health in Maryland. These creative centers generate innovations made in the U.S. that spread around the world and benefit everyone. Denmark is too small to sustain such centers by itself, but the problem extends to Europe more broadly, where policymakers struggle to match American innovation. Brooks is also correct about the danger of universal free college education. Those who graduate from four-year colleges will usually be in the upper half of the income distribution and should not expect to get a free ride from taxpayers who are making far less themselves. At the same time, creating broad financial support to allow children from low-income families to attend college while avoiding crippling debts is absolutely the right policy.

The U.S. is an exceptional country with a dynamic and successful economy. Europe would profit from copying the innovation culture of America. American capital markets, notwithstanding the financial crisis, are much more efficient than those in Europe and offer financial support and mentoring to start-up companies. Going the other way, America could learn about ways to retrain workers and avoid the desperate poverty that afflicts too many of our citizens. We could learn about the benefits of negotiating for lower prices from doctors, hospitals and drug companies. Whoever wins the White House should be secure in their belief about America’s strengths and vitality, while admitting that we can learn from what other countries do well.

The financial crisis is now eight years behind us, but its legacy lingers on. Many Americans are concerned about their financial security and are particularly worried about whether they will have enough for retirement. Guaranteed benefit pensions are gradually disappearing, leaving households to save and invest for themselves. What role could equities play for retail investors?

Another concern about the lingering impact of the crisis is that business investment and overall economic growth remains weak compared to expectations. Large companies are able to borrow at low interest rates, yet many of them have large cash holdings. However, many small and medium sized enterprises face difficulty funding their growth, paying high risk premiums on their borrowing and, in some cases, being unable to fund investments they would like to make. Equity funding can be an important source of growth financing.

On Friday, April 15, the Initiative on Business and Public Policy at Brookings examined what role equity markets can play for individual retirement security, small business investment and whether they can help jumpstart American innovation culture by fostering the transition from startups to billion dollar companies.

Australia's economic performance has been the standout among advanced economies for several decades. With economic growth at nearly twice the pace of US or Germany over the past decade, a remarkable 25 years without a recession and a large, highly competitive mining sector despite the end of the resources boom, Australia remains a strong economic participant in a region of the world where future global growth is likely to be generated.

But with drivers of growth over the past 25 years unlikely to be the engines of growth in coming decades, now is not a time for complacency. And if there's one lesson from Britain's decision to leave the EU, it's that that disruptive forces are sweeping through the global economy. Australia, with its cohesive politics and economic success, has been able to avoid the worst of these problems, but the dangers are present if the economic challenges are not met.

To start with, the impacts of the reforms of the 1980s and 1990s are fading. The investment boom in mining is over, and the prices for mining and agricultural exports will probably remain subdued with slower growth in China. While Australia's incomes were boosted by the improved terms of trade, this has partially reversed. The housing boom will inevitably eventually slow.

As evidenced by the results of the Brexit referendum, there is a distrust of the political and economic elites that have led the world's biggest economies. Disruptive, rapid changes in technology have not led to broad-based productivity growth. Workers in many countries have been left with stagnant incomes and governments with rising public debt.

Industry policy has a bad name among American economists who see it as a manifestation of "capture" where special interests are able to obtain subsidies from taxpayers or special protections that are not in the national interest. The modern theory of industry policy, however, recognises that a well-designed policy can actually help markets work better, therefore helping an economy like Australia's make the transition to a new growth path when faced with changing economic conditions. Productivity is the key to high growth and rising incomes – and well-designed industry policy can help.

Structure of trade competitiveness

Take, for example, Australia's manufacturing sector. Mostly because of comparative advantage, it is the smallest among all advanced economies relative to the size of its economy. In 2010, Germany had 21.2 per cent of its workforce in manufacturing while Australia's was 8.9 per cent. While it's not surprising that Australia's structure of trade competitiveness differs from Germany's because of its enormous export strength of mining and agriculture, it will benefit by taking advantage of its highly skilled workforce and the potential to develop industries based on this human capital – including advanced manufacturing industries.

One of the traditional strengths of the American economy is the close link that exists between leading universities and businesses – an area Australian policymakers are seeking to improve upon. At MIT and Stanford, professors of engineering, biology, finance or economics finish their lectures and head off to the companies they run or advise. They often enlist graduate or undergraduate students to help them with their commercial projects and these collaborations often result in jobs as well as experience. There is a danger in this model if pure research loses out to business interests, but the interaction between academia and the practical needs of companies can largely improve both research and business profitability. It's worth recalling that even the giants of science in the 18th century were motivated by the need to improve navigation or build new machines or design buildings. Funding for research should support greater industry-university cooperation as highlighted by the Watt Review.

Another important element in Australia's continued economic success is the growth of its service industries. With most jobs in these industries, the performance and productivity of services will be the largest determinant of Australia's living standards. Productivity comparisons between Australia and the United States show that Australian productivity lagged behind the US as recently as the mid-1990s, but there has since been substantial catch-up taking place. Smart regulation that promotes competition and rewards innovation are necessary to bring up the laggards. While there is a continuing debate about the possible end of productivity growth in advanced economies, Australia can still do much to catch up to global best practice.

The winners of this weekend's election will be charged with answering an important question: what is the role of government in a modern economy? How they answer that will determine future prosperity for all Australians.

High taxes, large government, poorly regulated markets (particularly labour markets), excessive debt and poor infrastructure undermine the drivers of growth. The realities of a fragile global economy and the need to build a solid foundation to generate productivity growth in Australia must be at the core of the policies that follow this election campaign.

Martin Baily is a senior fellow at the Brookings Institution in Washington and a former chair of the US President's Council of Economic Advisers. He has been invited by the Australian Ministry of Industry Innovation and Science to report on lessons from the US for policies to enhance economic growth, innovation and competitiveness.

Alaska Republican Sen. Lisa Murkowski’s write-in candidacy for reelection makes her the latest to join a growing number of prominent politicians who have shed political affiliations in the hopes of winning public office.

Florida Gov. Charlie Crist is running as an independent for the Senate, former Sen. Lincoln Chafee is running as an independent for Rhode Island governor, Mayor Michael Bloomberg became an independent to run New York City, and, of course, Sen. Joe Lieberman lost the 2006 Democratic Senate primary — but won in the general as an independent.

The trend of moderate independent candidates who have forsworn party affiliations is not new to U.S. politics. Since the Civil War, when the modern Republican Party was established to compete against the Democratic Party, minor party or unaffiliated candidates have won election to the House or Senate a total of 697 times. Of these, 89 percent of elected minor party candidates had voting records ideologically between the two major parties.

Despite the recent polarization of U.S. politics, history tells us that moderates make winners. Consider the Wisconsin Progressive Party. Its development has a familiar ring to today’s politics. Extremist elements flourished in the Republican Party during the Great Depression, growing out of our nation’s economic anxieties. GOP moderates responded by creating this Wisconsin group, focused on issues of reform and pragmatic governance.

It started when Wisconsin Gov. Philip La Follette ran for reelection in 1932 as the GOP nominee. He was heckled throughout his speeches by Republican ‘Stalwarts’ on his political right. They “had their Phil” and were angered by his policies of perceived higher taxes to support government spending. La Follette lost the Republican primary to Stalwart-backed Walter Kohler amid then-record turnout. Kohler lost to the Democrat in the general election.

La Follette is a famous political name. Gov. Philip La Follette and Sen. Robert La Follette Jr. were sons of the leading GOP politician, Sen. Robert La Follette Sr. Republican progressives had supported him for the party’s presidential nomination in 1912 and 1916. He eventually ran for president in 1924 — on his own Independent Progressive Party ticket. But while the father’s exploits are well-known, his sons’ reactions to Wisconsin’s political climate are more relevant to today’s politics.

Frustrated by the GOP extremists, the La Follette brothers created the Wisconsin Progressive Party, and they ran as party candidates when successfully elected governor and senator in 1934. Today’s independent candidates share a similar frustration with the ideological purists on their right and left. The extremists in the Democratic and Republican primary electorates are rejecting centrist candidates who might be better positioned to win general elections.

Consider the words of Crist when he declared his Independent candidacy. “If you want somebody on the right or you want somebody on the left,” Crist said, “you have the former speaker, Rubio, or the congressman, Meek. If you want somebody who has common sense, who puts the will of the people first, who wants to fight for the people first, now you've got Charlie Crist. You have a choice.”

With all the attention paid to the successes of Tea Party activists during the GOP primaries, it is easy to forget that these are not like general elections. Primary voters tend to be more ideologically extreme. So these Republican primary voters may end up denying the party several general election victories.

For example, many political observers agree that Rep. Mike Castle (R-Del.), a moderate, would have been a stronger candidate for Senate than the GOP primary victor, Christine O’Donnell, his tea party-backed opponent. General elections have traditionally been won in the center -- where most voters still reside.

Minor party successes usually arise when the two major political parties become ideologically polarized. Moderates can usually find a seat under a big tent, but when party activists are unable to tolerate dissent, moderates are shut out and left to their own devices. So it isn’t surprising that strong candidates holding moderate positions realize they are electorally viable by abandoning their party and appealing to the center in general elections.

History tells us that conditions now are favorable for moderates like Chafee, Crist, Lieberman, and Murkowski. They step into a political vacuum at the center that the major parties created by moving to the political extremes. With room left for further polarization, this may be just the beginning of the rise of moderate independent candidates.

History also tells us the political party that first figures out how to recapture the middle -- and bring these candidates and their supporters into the fold -- is the one most likely to emerge as dominant.

       

Analysis of dozens of publicly created redistricting plans shows that map-making technology can improve political representation and detect a gerrymander.  In 2012, President Obama won the vote in Ohio by three percentage points, while Republicans held a 13-to-5 majority in Ohio’s delegation to the U.S. House. After redistricting in 2013, Republicans held 12 of Ohio’s House seats while Democrats held four. As is typical in these races, few were competitive; the average margin of victory was 32 points. Is this simply a result of demography, the need to create a majority-minority district, and the constraints traditional redistricting principles impose on election lines—or did the legislature intend to create a gerrymander?

Crowd-Sourced Redistricting Maps

In the Ohio elections, we have a new source of information that opens a window into the legislature’s choice: Large numbers of publicly created redistricting plans.

During the last round of redistricting, across the country thousands of people in over a dozen states created hundreds of legal redistricting plans. Advances in information technology and the engagement of grassroots reform groups made these changes possible. To promote these efforts we created the DistrictBuilder open redistricting platform and many of these groups used this tool to create their plans.

Over the last several years, we have used the trove of information produced by public redistricting to gain insight into the politics of representation. In previous work that analyzed public redistricting in Virginia^[1], and in Florida^[2], we discovered that members of the public are capable of creating legal redistricting plans that outperform those maps created by legislatures in a number of ways.

Public redistricting in Ohio shows something new—the likely motives of the legislature. This can be seen through using information visualization methods to show the ways in which redistricting goals can be balanced (or traded-off) in Ohio , revealing the particular trade-offs made by the legislature.

The figure below, from our new research paper^[3], shows 21 plots—each of which compares legislative and publicly-created plans using a pair of scores—altogether covering seven different traditional and representational criteria. A tiny ‘A’ shows the adopted plan. The top-right corner of each mini-plot shows the best theoretically possible score. When examined by itself, the legislative plan meets a few criteria: it minimizes population deviation, creates an expected majority-minority seat, and creates a substantial majority of districts that would theoretically be competitive in an open-seat race in which the statewide vote was evenly split.

Figure 1: Pairwise Congressional Score Comparisons (Scatterplots) - Standardized Scores

In previous rounds of redistricting, empirical analysis would stop here—unless experts were called in to draw alternative plans in litigation. However, the large number of public plans now available allows us to see other options, plans the legislature could readily have created had it desired to do so. Comparison of the adopted plans and public plans reveal the weakness of the legislature’s choice. Members of the public were able to find plans that soundly beat the legislative plan on almost every pair of criteria, including competitive districts.

So why was the adopted plan chosen? Information visualization can help here, as well, but we need to add another criterion—partisan advantage:

Pareto Frontier: Standard Criteria vs. Democratic Surplus

When we visualize the number of expected Democratic seats that was likely to result from each plan, and compare this to the other score, we can see that the adopted plan is the best at something— producing Republican seats.

Was Ohio gerrymandered? Applying our proposed gerrymandering detection method, the adopted plans stands in high contrast to the public sample of plans, even if the overall competition scoring formula is slightly biased towards the Democrats, as strongly biased towards the Republicans on any measure of partisan fairness. Moreover analyzing the tradeoffs among redistricting criteria illuminate empirically demonstrates what is often suspected, but is typically impossible to demonstrate—that had the legislature desired to improve any good-government criterion—it could have done so, simply by sacrificing some partisan advantage. In light of this new body of evidence, the political intent of the legislature is clearly displayed.

However, when politics and technology mix, beware of Kranzberg’s first law: “Technology is neither good nor bad; nor is it neutral.”^[4] Indeed there is an unexpected and hopeful lesson on reform revealed by the public participation that was enabled by new technology. The public plans show that, in Ohio, it is possible to improve the expected competitiveness, and to improve compliance with traditional districting principles such as county integrity, without threatening majority-minority districts simply by reducing partisan advantage—this is a tradeoff we should gladly accept.

       

       

NASA’s Asteroid Initiative encompasses efforts for the human exploration of asteroids—as well as the Asteroid Grand Challenge—to enhance asteroid detection capabilities and mitigate their threat to Earth. The human space flight portion of the initiative primarily includes the Asteroid Redirect Mission (ARM), which is a proposal to put an asteroid in orbit of the moon and send astronauts to it. The program originally contemplated two alternatives for closer study: capturing a small 10m diameter asteroid versus simply recovering a boulder from a much larger asteroid. Late in March, NASA offered an update of its plans. It has decided to retrieve a boulder from an asteroid near Earth’s orbit—candidates are the asteroids 2008 EV5, Bennu, and Itokawa—and will place the boulder on the moon’s orbit to further study it.

This mission will help NASA develop a host of technical capabilities. For instance, Solar Electric Propulsion uses solar electric power to charge atoms for spacecraft propulsion—in the absence of gravity, even a modicum of force can alter the trajectory of a body in outer space. Another related capability under development is the gravity tractor, which is based on the notion that even the modest mass of a spacecraft can exert sufficient gravitational force over an asteroid to ever so slightly change its orbit. The ARM spacecraft mass could be further increased by its ability to capture a boulder from the asteroid that is steering clear of the Earth, enabling a test of how humans might prevent asteroid threats in the future. Thus, NASA will have a second test of how to deflect near-Earth objects on a hazardous trajectory. The first test, implemented as part of the Deep Impact Mission, is a kinetic impactor; that is, crashing a spacecraft on an approaching object to change its trajectory.

The Asteroid Initiative is a partner of the agency’s Near Earth Object Observation (NEOO) program. The goal of this program is to discover and monitor space objects traveling on a trajectory that could pose the risk of hitting Earth with catastrophic effects. The program also seeks to develop mitigation strategies. The capabilities developed by ARM could also support other programs of NASA, such as the manned exploration of Mars.

NEOO has recently enjoyed an uptick of public support. It used to be funded at about $4 million in the 1990s and in 2010 was allocated a paltry $6 million. But then, a redirection of priorities—linked to the transition from the Bush to the Obama administrations—increased funding for NEOO to about $20 million in 2012 and $40 million in 2014—and NASA is seeking $50 million for 2015. It is clear that NASA officials made a compelling case for the importance of NEOO; in fact, what they are asking seems quite a modest amount if indeed asteroids pose an existential risk to life on earth. At the same time, the instrumental importance of the program and the public funds devoted to it beg the question as to whether taxpayers should have a say in the decisions NASA is making regarding how to proceed with the program.

NASA has done something remarkable to help answer this question.

Last November, NASA partnered with the ECAST network (Expert and Citizen Assessment of Science and Technology) to host a citizen forum assessing the Asteroid Initiative. ECAST is a consortium of science policy and advocacy organizations which specializes in citizen deliberations on science policy. The forum consisted of a dialogue with 100 citizens in Phoenix and Boston who learned more about the asteroid initiative and then commented on various aspects of the project.

The participants, who were selected to approximate the demographics of the U.S. population, were asked to assess mitigation strategies to protect against asteroids. They were introduced to four strategies: civil defense, gravity tractor, kinetic impactor, and nuclear blast deflection. As part of the deliberations, they were asked to consider the two aforementioned approaches to perform ARM. A consensus emerged about the boulder retrieval option primarily because citizens thought that option offered better prospects for developing planetary defense technologies.  This preference existed despite the excitement of capturing a full asteroid, which could potentially have additional economic impacts. The participants showed interest in promoting the development of mitigation capabilities at least as much as they wanted to protect traditional NASA goals such as the advancement of science and space flight technology. This is not surprising given that concerns about doomsday should reasonably take precedence over traditional research and exploration concerns.

NASA could have decided to set ARM along the path of boulder retrieval exclusively on technical merits, but having conducted a citizen forum, the agency is now able to claim that this decision is also socially robust, which is to say, is responsive to public values of consensus. In this manner, NASA has shown a promising method by which research mission federal agencies can increase their public accountability.

In the same spirit of responsible research and innovation, a recent Brookings paper I authored with David Guston—who is a co-founder of ECAST—proposes a number of other innovative ways in which the innovation enterprise can be made more responsive to public values and social expectations.

Kudos to NASA for being at the forefront of innovation in space exploration and public accountability.

      

The fiscal budget has become a casualty of political polarization and even functions that had enjoyed bipartisan support, like research and development (R&D), are becoming divisive issues on Capitol Hill. As a result, federal R&D is likely to grow pegged to inflation or worse, decline.

With the size of the pie fixed or shrinking, requests for R&D funding increases will trigger an inter-agency zero-sum game that will play out as pointless comparisons of agencies’ merit, or worse, as a contest to attract the favor of Congress or the White House. This insidious politics will be made even more so by the growing tendency of equating public accountability with the measurement of performance. Political polarization, tight budgets, and pressure for quantifiable results threaten to undermine the sustainability of public R&D. The situation begs the question: What can federal agencies do to deal with the changing politics of federal R&D?

In a new paper, Walter D. Valdivia and Benjamin Y. Clark apply punctuated equilibrium theory to examine the last four decades of federal R&D, both at the aggregate and the agency level. Valdivia and Clark observe a general upward trend driven by gradual increases. In turn, budget leaps or punctuations are few and far in between and do no appear to have lasting effects. As the politics of R&D are stirred up, federal departments and agencies are sure to find that proposing punctuations is becoming more costly and risky. Consequently, agencies will be well advised in securing stable growth in their R&D budgets in the long run rather than pushing for short term budget leaps.

While appropriations history would suggest the stability of R&D spending resulted from the character of the budget politics, in the future, stability will need the stewardship of R&D champions who work to institutionalize gradualism, this time, in spite of the politics.

Federal departments and agencies received just above $133 billion in R&D funds in 2013. To put that figure in perspective, World Bank data for 2013 shows that, 130 countries had a GDP below that level; U.S. R&D is larger than the entire economy of 60 percent of all countries in the world.

The chart below shows how those funds are allocated among the most important federal departments and agencies in terms of R&D.

Those looking at these figures for the first time may be surprised to see that the Department of Defense takes about half of the pie. It should be noted however that not all federal R&D is destined to preserve U.S. military preeminence in the world. From non-defense research, 42 percent is destined to the much-needed research conducted by the National Institutes of Health, 17 percent to the research of the Department of Energy—owner of 17 celebrated national laboratories—16 percent for space exploration, and 8 percent for understanding the natural and social worlds at a fundamental level. The balance category is only lumped together for visual display not for its importance; it includes for instance the significant work of the National Oceanic and Atmospheric Administration and the National Institute of Standards and Technology.

Despite the impressive size of defense R&D, we hear little about it. While much of defense research and development is classified, in time, civilian applications find their way into mainstream commercial uses—the Internet and GPS emerged from research done at DARPA. Far more visible than defense R&D is biomedical research, clean energy research, or news about truly impressive discoveries either in distant galaxies or in the depths of our oceans.

What produces this asymmetry of visibility of federal R&D work?

In a recent Brookings paper, a colleague and I suggest that the answer lies in the prominence of R&D in the agencies’ accounting books. In short: How visible is R&D and how much the agency seeks to discuss it in public fora depends not on the relative importance, but on how large a portion of the agency’s budget is dedicated to R&D.

From a budget perspective, we identified two types of agencies performing R&D: those agencies whose main mission is to perform research and development, and those agencies that perform many functions in addition to R&D. For the former, the share of R&D in the discretionary budget is consistently high, while for the latter group, R&D is only a small part of their total budget (see the chart below). This distinction influences how agencies will argue for their R&D money, because they will make their case on the most important uses of their budget. If agencies have a low R&D share, they will keep it mixed with other functions and programs; for instance, research efforts will be justified only as supporting the main agency mission. In turn, agencies with a high R&D share must argue for their budgets highlighting the social outcomes of their work. These include three agencies whose primary mission is research (NASA, NSF, NIH), and a fourth (DoE) where research is a significant element of its mission.

There is little question that the four agencies with high R&D share produce greatly beneficial research for society. Their strategy of promoting their work publicly is not only smart budget politics but also civic and pedagogical in the sense of helping taxpayers understand that their tax dollars are well-spent. However, it is interesting to observe that other agencies may be producing research of equal social impact that flies under the public radar, mainly because those agencies prefer as a matter of good budget policy to keep a low profile for their R&D work.

One interesting conclusion for institutional design from this analysis is that promoting a research agency to the level of departments of government or its director to a cabinet rank position may bring prominence to its research, not because more and better research will necessarily get done but simply because that agency will seek public recognition for their work in order to justify its budget. Likewise, placing a research agency within a larger department may help conceal and protect their R&D funding; the politics of the department will focus on its main goals and R&D would recede to a concern of secondary interest in political battles.

In the Politics of Federal R&D we discuss in more detail the changing politics of budget and how R&D agencies can respond. The general strategies of concealment and self-promotion are likely to become more important for agencies to protect a steady growth of their research and development budgets.

International development debates of the last four decades have ascribed ever greater importance to intellectual property rights (IPRs). There has also been a significant effort on the part of the U.S. to encourage its trade partners to introduce and enforce patent law modeled after American intellectual property law. Aside from a discussion on the impact of patents on innovation, there are some important consequences of international harmonization regarding the obduracy of the terms of trade agreements.

The position of the State Department on patents when negotiating trade agreements has consistently been one of defending stronger patent protection. However, the high-tech sector is under reorganization, and the most innovative industries today have strong disagreements about the value of patents for innovation. This situation begs the question as to why the national posture on patent law is so consistent in favor of industries such as pharmaceuticals or biotech to the detriment of software developers and Internet-based companies.

The State Department defends this posture, arguing that the U.S. has a comparative advantage in sectors dependent on patent protection. Therefore, to promote exports, our national trade policy should place incentives for partners to come in line with national patent law. This posture will become problematic when America’s competitive advantage shifts to sectors that find patents to be a hindrance to innovation, because too much effort will have already been invested in twisting the arm of our trade partners. It will be hard to undo those chapters in trade agreements particularly after our trade partners have taken pains in passing laws aligned to American law.

Related to the previous concern, the policy inertia effect and inflexibility applies to domestic policy as much as it does to trade agreements. When other nations adopt policy regimes following the American model, advocates of stronger patent protection will use international adoption as an argument in favor of keeping the domestic policy status quo. The pressure we place on our trade partners to strengthen patent protection (via trade agreements and other mechanisms like the Special 301 Report) will be forgotten. Advocates will present those trade partners as having adopted the enlightened laws of the U.S., and ask why American lawmakers would wish to change law that inspires international emulation. Innovation scholar Timothy Simcoe has correctly suggested that harmonization creates inflexibility in domestic policy. Indeed, in a not-too-distant future the rapid transformation of the economy, new big market players, and emerging business models may give policymakers the feeling that we are stuck in a patent policy rut whose usefulness has expired.

In addition, there are indirect economic effects from projecting national patent law onto trade agreements. If we assume that a club of economies (such as OECD) generate most of the innovation worldwide while the rest of countries simply adopt new technologies, the innovation club would have control over the global supply of high value-added goods and services and be able to preserve a terms-of-trade advantage. In this scenario, stronger patent protection may be in the interest of the innovation club to the extent that their competitive advantage remains in industries dependent of patent protection. But should the world economic order change and the innovation club become specialized in digital services while the rest of the world takes on larger segments of manufactures, the advantage may shift outside the innovation club. This is not a far-fetched scenario. Emerging economies have increased their service economy in addition to their manufacturing capacity; overall they are better integrated in global supply chains. What is more, these emerging economies are growing consumption markets that will become increasingly more relevant globally as they continue to grow faster than rich economies.

What is more, the innovation club will not likely retain a monopoly on global innovation for too long. Within emerging economies, another club of economies is placing great investments in developing innovative capacity. In particular, China, India, Brazil, Mexico, and South Africa (and possibly Russia) have strengthened their innovation systems by expanding public investments in R&D and introducing institutional reforms to foster entrepreneurship. The innovation of this second club may, in a world of harmonized patent law, increase their competitive advantage by securing monopolistic control of key high-tech markets. As industries less reliant on patents flourish and the digital economy transforms US markets, an inflexibly patent policy regime may actually be detrimental to American terms of trade.

I should stress that these kind of political and economic effects of America’s posture on IPRs in trade policy are not merely speculative. Just as manufactures displaced the once dominant agricultural sector, and services in turn took over as the largest sector of the economy, we can fully expect that the digital economy—with its preference for limited use of patents—will become not only more economic relevant, but also more politically influential. The tensions observed in international trade and especially the aforementioned considerations merit revisiting the rationale for America’s posture on intellectual property policy in trade negotiations.

After a recent talk about my ISIS book, one of the audience members asked, “What can I read to help me not hate Islam?” I don’t think it’s a scholar’s job to persuade others to love or hate any culture. But the question was sincere, so I suggested some books that have helped me better understand Islam. I also put the question to Twitter. Below is some of what I and others came up with.

Two cautions before we dive in: First, the list is obviously not exhaustive and I’ve left out overly apologetic books—in my experience, they only increase the skeptical reader’s suspicion that she’s being suckered. Second, people on Twitter gave me great suggestions but I’ve only included those I’ve read and can vouch for:

Muhammad and the Quran: Two of the best books you’ll ever read about Muhammad and the Quran are also the shortest: The Koran: A Very Short Introduction and Muhammad, both by Michael Cook. He writes with great wit and deep scholarship.

Other scriptures: Most non-Muslims are unaware that Islamic scripture is more than the Quran. It includes a vast collection of words and deeds attributed to Muhammad by later authors. These scriptures are sort of like the Gospels, and Muslim scholars fight over their authenticity like Christian scholars debate about the accuracy of Matthew, Mark, Luke, and John. These extra Islamic scriptures contain most of the teachings that make modern people (Muslims included) uncomfortable about Islam. One of the world’s experts on these scriptures, Jonathan Brown, has written a terrific book about them, Misquoting Muhammad.

Rumi: The medieval mystic’s poems about life and death are beautiful and moving, no matter your belief system. I loved his poems so much as an undergrad that I went on to study Middle Eastern languages just so I could read his work in the original. I’m glad I first viewed Islam through the eyes of Rumi and not a group like ISIS. Neither is solely representative of Islam but both draw heavily on its scriptures and reach such different conclusions.

The Bible: Many people recommended reading the Bible to decrease hate of Islam. The nerd in me leapt to the least obvious conclusion, “Ah, good idea! Reading some of the rough stuff in the Hebrew Bible is a good way to put a kindred ancient religion like Islam in perspective.” But they meant something a little less complicated:

@will_mccants @jenanmoussa Read the bible and learn to love and not to hate. :-)

It’s a worthy perspective today no matter your faith.

By most metrics, the 1991 Gulf War, also known as Operation Desert Storm, was a huge and rapid success for the United States and its allies. The mission of defeating Iraq's army, which invaded Kuwait the year prior, was done swiftly and decisively. However, the war's impact on soldiers who fought in it was lasting. Over 650,000 American men and women served in the conflict, and many came home with symptoms including insomnia, respiratory disorders, memory issues and others attributed to a variety of exposures – “Gulf War Illness."

On June 16, the Center for 21st Century Security and Intelligence at Brookings and Georgetown University Medical Center co-hosted a discussion on Desert Storm, its veterans, and how they are faring today. Representative Mike Coffman (R-Col.), the only member of Congress to serve in both Gulf wars, delivered an opening address before joining Michael O’Hanlon, senior fellow at Brookings, for a moderated discussion. Joel Kupersmith, former head of the Office of Research and Development of the Department of Veterans Affairs, convened a follow-on panel with Carolyn Clancy, deputy under secretary for health for organizational excellence at the Department of Veterans Affairs; Adrian Atizado, deputy national legislative director at Disabled American Veterans; and James Baraniuk, professor of medicine at Georgetown University Medical Center.

The terrible attack in Nice on July 14—Bastille Day—saddened us all. For a country that has done so much historically to promote democracy and human rights at home and abroad, France is paying a terrible and unfair price, even more than most countries. My colleagues Will McCants and Chris Meserole have carefully documented the toll that France, and certain other Francophone countries like Belgium, have suffered in recent years from global terrorism. It is heart wrenching.

From what we know so far, the attack was carried out by a deeply distraught, potentially deranged, and in any case extremely brutal local man from Nice of Tunisian descent and French nationality. Marital problems, the recent loss of his job, and a general sense of personal unhappiness seem to have contributed to the state of mind that led him to commit this heinous atrocity. Perhaps we will soon learn that ISIS, directly or indirectly, inspired the attack in one way or another as well. My colleague Dan Byman has already tapped into his deep expertise about terrorism to remind us that ISIS had in fact encouraged ramming attacks with vehicles before, even if the actual manifestation of such tactics in this case was mostly new. 

This attack will again raise the question: Why France? On this point, I do have a somewhat different take than some of my colleagues. The argument that France has partly brought these tragedies upon itself—perhaps because of its policies of secularism and in particular its limitations on when and where women can wear the veil in France—strikes me as unpersuasive. Its logical policy implications are also potentially disturbing, because if interpreted wrongly, it could lead to a debate on whether France should modify such policies so as to make itself less vulnerable to terrorism. That outcome, even if unintended, could dance very close to the line of encouraging appeasement of heinous acts of violence with policy changes that run counter to much of what French culture and society would otherwise favor. So I feel the need to push back.

Here are some of the arguments, as I see them, against blaming French culture or policy for this recent string of horrible attacks including the Charlie Hebdo massacre, the November 2015 mass shootings in Paris, and the Nice tragedy (as well as recent attacks in Belgium):

• Starting with the simplest point, we still do not know much about the perpetrator of the Nice killings. From what we do surmise so far, personal problems appear to be largely at the root of the violence—different from, but not entirely unlike, the case with the Orlando shooter, Omar Mateen.
• We need to be careful about drawing implications from a small number of major attacks. Since 2000, there have also been major attacks in the Western world by extremist jihadis or takfiris in New York, Washington, Spain, London, San Bernardino, Orlando, and Russia. None of these are Francophone. Even Belgium is itself a mixed country, linguistically and culturally.
• Partly for reasons of geography, as well as history, France does face a larger problem than some other European countries of individuals leaving its country to go to Syria or Iraq to fight for ISIS, and then returning. But it is hardly unique in the scale of this problem.
• Continental Europe has a specific additional problem that is not as widely shared in the United Kingdom or the United States: Its criminal networks largely overlap with its extremist and/or terrorist networks. This point may be irrelevant to the Nice attack, but more widely, extremists in France or Belgium can make use of illicit channels for moving people, money, and weapons that are less available to would-be jihadis in places like the U.K. (where the criminal networks have more of a Caribbean and sub-Saharan African character, meaning they overlap less with extremist networks).
• Of course, the greatest numbers of terrorist attacks by Muslim extremists occur in the broader Muslim world, with Muslims as the primary victims—from Iraq and Syria to Libya and Yemen and Somalia to South Asia. French domestic policies have no bearing on these, of course.

There is no doubt that good work by counterterrorism and intelligence forces is crucial to preventing future attacks. France has done well in this regard—though it surely can do better, and it is surely trying to get better. There is also no doubt that promoting social cohesion in a broad sense is a worthy goal. But I would hesitate, personally, to attribute any apparent trend line in major attacks in the West to a particular policy of a country like France—especially when the latter is in fact doing much to seek to build bridges, as a matter of national policy, with Muslims at home and abroad. 

There is much more to do in promoting social cohesion, to be sure, even here in America (though our own problems probably center more on race than on religion at the moment). But the Nice attacker almost assuredly didn’t attack because his estranged wife couldn’t wear a veil in the manner and/or places she wanted. At a moment like this in particular, I disagree with insinuations to the contrary.

       

       

       

       

       

       

       

I had the pleasure earlier this month of welcoming my friend, Czech Republic Foreign Minister Lubomir Zaoralek, here to Brookings for a discussion of critical issues confronting the Europe-U.S. alliance. Foreign Minister Zaoralek was appointed to his current position in January 2014 after serving as a leading figure in the Czech Parliament for many years. He was accompanied by a distinguished delegation that included Dr. Petr Drulak of the Foreign Ministry, and Czech Ambassador Petr Gandalovic. I was fortunate enough to be joined in the discussion by colleagues from Brookings including Fiona Hill, Shadi Hamid, Steve Pifer, and others, as well as representatives of other D.C. think tanks. Our discussion spanned the globe, from how to respond to the Syrian conflict, to addressing Russia’s conduct in Ukraine, to the thaw in U.S.-Cuba relations, to dealing with the refugee crisis in Europe. The conversation was so fascinating that the sixty minutes we had allotted flew by and we ended up talking for two hours—and we still just scratched the surface.

Amb. Eisen and FM Zaoralek, October 2, 2015

Yesterday, we had a visit from Czech State Secretary Tomas Prouza, accompanied by Ambassador Martin Povejsil, the Czech Permanent Envoy to the EU. We also talked about world affairs. In this case, that included perhaps the most important governance matter now confronting the U.S.: the exceptionally entertaining (if not enlightening) presidential primary season. I expressed my opinion that Vice President Biden would not enter the race, only to have him prove me right in his Rose Garden remarks a few hours later. If only all my predictions came true (and as quickly). We at Brookings benefited greatly from the insights of both of these October delegations, and we look forward to welcoming many more from every part of the Czech political spectrum in the months ahead.

A conversation with VA Secretary Robert McDonald

This program was aired live on CSPAN.org » 

With the demand for its services constantly evolving, the Department of Veterans Affairs (VA) faces complex challenges in providing accessible care to America’s veterans. Amidst a history of long patient wait times, cost overruns, and management concerns, the VA recently conducted a sweeping internal review of its operations.  The result was the new MyVA program.

How will MyVA improve the VA’s care of veterans? What will it do restore public confidence in its efforts? What changes is the VA undergoing to address both internal concerns and modern challenges in veteran care? 

On June 20, Governance Studies at Brookings hosted VA Secretary Robert McDonald. Secretary McDonald described the VA’s transformation strategy and explained how the reforms within MyVA will impact veterans, taxpayers and other stakeholders. He addressed lessons learned not just for the VA but for all government agencies that strive to achieve transformation and improve service delivery.

This week marks the release of the 2015 Brown Center Report on American Education, the fourteenth issue of the series.  One of the three studies in the report, “Girls, Boys, and Reading,” examines the gender gap in reading.  Girls consistently outscore boys on reading assessments.  They have for a long time.  A 1942 study in Iowa discovered that girls were superior to boys on tests of reading comprehension, vocabulary, and basic language skills.^[i]  Girls have outscored boys on the National Assessment of Educational Progress (NAEP) reading assessments since the first NAEP was administered in 1971. 

I hope you’ll read the full study—and the other studies in the report—but allow me to summarize the main findings of the gender gap study here.

Eight assessments generate valid estimates of U.S. national reading performance: the Main NAEP, given at three grades (fourth, eighth, and 12^th grades); the NAEP Long Term Trend (NAEP-LTT), given at three ages (ages nine, 13, and 17); the Progress in International Reading Literacy Study (PIRLS), an international assessment given at fourth grade; and the Program for International Student Assessment (PISA), an international assessment given to 15-year-olds.  Females outscore males on the most recent administration of all eight tests.  And the gaps are statistically significant.  Expressed in standard deviation units, they range from 0.13 on the NAEP-LTT at age nine to 0.34 on the PISA at age 15.

The gaps are shrinking.  At age nine, the gap on the NAEP-LTT declined from 13 scale score points in 1971 to five points in 2012.  During the same time period, the gap at age 13 shrank from 11 points to eight points, and at age 17, from 12 points to eight points.  Only the decline at age nine is statistically significant, but at ages 13 and 17, declines since the gaps peaked in the 1990s are also statistically significant.  At all three ages, gaps are shrinking because of males making larger gains on NAEP than females.  In 2012, seventeen-year-old females scored the same on the NAEP reading test as they did in 1971.  Otherwise, males and females of all ages registered gains on the NAEP reading test from 1971-2012, with males’ gains outpacing those of females.

The gap is worldwide.  On the 2012 PISA, 15-year-old females outperformed males in all sixty-five participating countries.  Surprisingly, Finland, a nation known for both equity and excellence because of its performance on PISA, evidenced the widest gap.  Girls scored 556 and boys scored 494, producing an astonishing gap of 62 points (about 0.66 standard deviations—or more than one and a half years of schooling).   Finland also had one of the world’s largest gender gaps on the 2000 PISA, and since then it has widened.  Both girls’ and boys’ reading scores declined, but boys’ declined more (26 points vs. 16 points).  To put the 2012 scores in perspective, consider that the OECD average on the reading test is 496.  Finland’s strong showing on PISA is completely dependent on the superior performance of its young women.

The gap seems to disappear by adulthood.  Tests of adult reading ability show no U.S. gender gap in reading by 25 years of age.  Scores even tilt toward men in later years. 

The words “seems to disappear” are used on purpose.  One must be careful with cross-sectional data not to assume that differences across age groups indicate an age-based trend.  A recent Gallup poll, for example, asked several different age groups how optimistic they were about finding jobs as adults.  Optimism fell from 68% in grade five to 48% in grade 12.  The authors concluded that “optimism about future job pursuits declines over time.”  The data do not support that conclusion.  The data were collected at a single point in time and cannot speak to what optimism may have been before or after that point.  Perhaps today’s 12^th graders were even more pessimistic several years ago when they were in fifth grade.  Perhaps the 12^th-graders are old enough to remember when unemployment spiked during the Great Recession and the fifth-graders are not.   Perhaps 12^th-graders are simply savvier about job prospects and the pitfalls of seeking employment, topics on which fifth-graders are basically clueless.

At least with the data cited above we can track measures of the same cohorts’ gender gap in reading over time.  By analyzing multiple cross-sections—data collected at several different points in time—we can look at real change.  Those cohorts of nine-year-olds in the 1970s, 1980s, and 1990s, are—respectively—today in their 50s, 40s, and 30s.  Girls were better readers than boys when these cohorts were children, but as grown ups, women are not appreciably better readers than men.

Care must be taken nevertheless in drawing firm conclusions.  There exists what are known as cohort effects that can bias measurements.  I mentioned the Great Recession.   Experiencing great historical cataclysms, especially war or economic chaos, may bias a particular cohort’s responses to survey questions or even its performance on tests.  American generations who experienced the Great Depression, World War II, and the Vietnam War—and more recently, the digital revolution, the Great Recession, and the Iraq War—lived through events that uniquely shape their outlook on many aspects of life. 

What Should be Done?

The gender gap is large, worldwide, and persistent through the K-12 years. What should be done about it?  Maybe nothing.  As just noted, the gap seems to dissipate by adulthood.  Moreover, crafting an effective remedy for the gender gap is made more difficult because we don’t definitely know its cause. Enjoyment of reading is a good example.  Many commentators argue that schools should make a concerted effort to get boys to enjoy reading more.  Enjoyment of reading is statistically correlated with reading performance, and the hope is that making reading more enjoyable would get boys to read more, thereby raising reading skills.

It makes sense, but I’m skeptical.  The fact that better readers enjoy reading more than poor readers—and that the relationship stands up even after boatloads of covariates are poured into a regression equation—is unpersuasive evidence of causality.  As I stated earlier, PISA produces data collected at a single point in time.  It isn’t designed to test causal theories.  Reverse causality is a profound problem.  Getting kids to enjoy reading more may in fact boost reading ability.  But the causal relationship might be flowing in the opposite direction, with enhanced skill leading to enjoyment.   The correlation could simply be indicating that people enjoy activities that they’re good at—a relationship that probably exists in sports, music, and many human endeavors, including reading.

A Key Policy Question

A key question for policymakers is whether boosting boys’ enjoyment of reading would help make boys better readers.  I investigate by analyzing national changes in PISA reading scores from 2000, when the test was first given, to 2102.  PISA creates an Index of Reading Enjoyment based on several responses to a student questionnaire.  Enjoyment of reading has increased among males in some countries and decreased in others.  Is there any relationship between changes in boys’ enjoyment and changes in PISA reading scores? 

There is not.  The correlation coefficient for the two phenomena is -0.01.  Nations such as Germany raised boys’ enjoyment of reading and increased their reading scores by about 10 points on the PISA scale.  France, on the other hand, also raised boys’ enjoyment of reading, but French males’ reading scores declined by 15 points.  Ireland increased how much boys enjoy reading by a little bit but the boys’ scores fell a whopping 37 points. Poland’s males actually enjoyed reading less in 2012 than in 2000, but their scores went up more than 14 points.  No relationship.

Some Final Thoughts

How should policymakers proceed?  Large, cross-sectional assessments are good for measuring academic performance at one point in time.  They are useful for generating hypotheses based on observed relationships, but they are not designed to confirm or reject causality.  To do that, randomized control trials should be conducted of programs purporting to boost reading enjoyment.  Also, consider that it ultimately may not matter whether enjoying reading leads to more proficient readers.  Enjoyment of reading may be an end worthy of attainment irrespective of its relationship to achievement.  In that case, RCTs should carefully evaluate the impact of interventions on both enjoyment of reading and reading achievement, whether the two are related or not.
