Why is Springfield's economy proving so resilient?

Several reasons come to mind: You're a manageably sized regional hub. You've got a university and important hospital assets. And you stand at the brink of an enormously attractive natural area -- the Ozarks.

More and more in today's footloose economy, jobs and people flock to livable places with affordable housing, vibrant downtowns, cultural amenities and lots of close-by outdoor recreation.

And Springfield's got all that. Well, OK: Downtown hardly buzzes with "24-7" meeting and living as yet. But the university keeps students around, and meanwhile, nearby Branson remains one of the nation's foremost "drive-to" cultural attractions. Likewise, the beautiful "lake country" draws visitors and second-home buyers from all over the Midwest. In this case natural beauty really is natural capital: The famous Ozarks ambience continues to support a $1-billion-a-year tourist sector to cushion the blows of any national economic downturn.

No wonder the region paced the state's growth in the 1990s and now holds on better in bad times. Greater Springfield has service jobs, rolling hills, lakes, Andy Williams, retirees and their pensions, and reasonably priced new subdivisions. What's not to like?

But here's the harder question: Can Springfield stay attractive? Can it stay resilient? The worry is that signs of strain have now appeared after a decade of fast growth.

Many of these strains my colleagues and I detailed in a recent Brookings Institution report I co-authored, titled "Growth in the Heartland: Challenges and Opportunities for Missouri."

Springfield, we demonstrated, sprawled in the 1990s. Yes, the city proper grew by 8 percent. But mostly population moved ever outward during the decade, and that, we said, has brought problems.

Thousands of people flocked to smaller outlying towns like Willard, Strafford, Republic, Clever, Nixa and Ozark, which hit "hypergrowth" in the 1990s and struggled to keep up. Christian and Webster counties grew unsustainably by 66 and 31 percent, respectively. And even more disturbing some 28,000 people settled in unincorporated fringe areas ill-equipped to accommodate them with modern sewers and good services.

The result: Septic and fertilizer seepage from scattered new homes exacerbates the water-quality problems that have fouled Lake Taneycomo and Table Rock Lake. Taxes are increasing as local governments strain to provide the necessary roads, services or sewer lines in places that never needed them. And with more sprawl coming, more traffic and more mini-malls could cost the region its reputation as the heartland of rural America -- quaint, scenic and friendly. The bottom line: Highly dispersed, low-density development may well be undermining the durability of its growth.

In that sense, the real test of Springfield's resilience lies ahead and turns on its ability to manage its growth to make it sustainable. What is more, the best way for Springfield to continue to grow in high-quality ways would seem to be to continue to set the standard for land-use and environmental reform in Missouri -- a state that has lagged on promoting sensible land use and planning.

As a state, after all, Missouri needs to update its badly outmoded planning statutes to provide its regions more tools to manage change.

It needs to promote regional solutions among its many localities. And it needs to better align its transportation and infrastructure investment policies with the principles of sound land use and sensible planning.

In this regard, what the state does -- or doesn't do -- to manage growth matters for Springfield because, ultimately, it is the state that sets the rules for what type of growth occurs all over. By remaining virtually laissez-faire on growth and development topics, the state of Missouri may well be undercutting its future competitiveness.

Given that, Springfield should take seriously the fact that with its strong growth, fresh voice and signature environmental assets, it is well positioned to lead the state in promoting reform.

So Springfield should step forward on these issues -- as the state's new economic driver, and as its most progressive region.

Already southwest Missouri business leaders have come together to protect the lakes. Now the region should show the way in other ways, by hammering out a regional system for managing fast growth; rationalizing local government competition; and insisting on state action to allow all regions to make headway.

For that is the way for the Springfield region to prosper: To help itself, it must help nudge the entire state along. Only in that fashion will a distinctive region maintain its distinctive vitality.

On Thursday, July 7, the International Monetary Fund (IMF) revised its economic outlook for South Africa. Despite “considerable economic and social progress” since 1994, the IMF report cited high income inequality, among other factors, in its projection of slow growth and increased unemployment in the medium term. Earlier this year, in the Brookings Africa Growth Initiative’s Foresight Africa 2016, we explored this pressing problem—high income inequality—across the continent. The initial takeaway was that sub-Saharan Africa has greater in-country income inequality than other developing countries around the world. However, after separating seven outlier economies—Angola, the Central African Republic, Botswana, Zambia, Namibia, Comoros, and South Africa—we noted that income inequality, measured by the Gini coefficient, in the rest of the region actually mirrors the rest of the developing world, which currently stands at 0.39. All seven outlier economies have Gini coefficients above 0.55, a level reached by only four other countries worldwide: Suriname, Haiti, Colombia, and Honduras. 

It is important to explore precisely why this disparity exists. Notably, sub-Saharan Africa is not only an outlier in income inequality, but also in the relationship between economic growth and poverty reduction. Generally, in the developing world, every 1 percent of growth reduces poverty 4 percent. In sub-Saharan Africa, however, every 1 percent of growth only reduces poverty by 3 percent. In Foresight Africa 2016, Brookings Nonresident Senior Fellow Haroon Bhorat suggests that this disparity may be because of the commodity booms that have sustained growth periods in African economies, which bring extraordinary returns to capital but limited job growth. Alternatively, these commodity booms may have accompanied a fall in manufacturing output; growth is thus concentrated in the low-productivity services sector. In any case, this graph forces us to consider exactly what type of structural transformation is necessary for continued economic growth and acknowledge that inequality in sub-Saharan Africa might require different solutions in different countries.

For a more in-depth discussion on this issue, see Foresight Africa 2016 and Bhorat’s discussion of African inequality in relation to the Sustainable Development Goals.

On May 17, Egyptian President Abdel-Fatah el-Sissi did something Egyptian presidents have done many times before: he urged Israel and the Palestinians to renew negotiations for peace, this time by backing an international conference promoted by the French foreign minister.

But what made Sissi’s call particularly interesting is that he called on not just the leaders but also political "parties" to seize what he called “a real opportunity to find a long-awaited solution.” Sissi's call offered Israeli Prime Minister Benjamin Netanyahu an opportunity to accommodate Israel's newest best friend, Sissi, rather than the French themselves. It would not have brought peace, of course: though an international conference would offer a glimmer of hope to change some of the worst aspects of the current diplomatic deadlock, it would not solve any of the outstanding substantive issues between Israelis and Palestinians.

Sissi's reference to political parties was no coincidence: it fit perfectly with the domestic political needs of Netanyahu and of Opposition Leader Isaac Herzog, who were angling to bring the Zionist Union joint list into the government and give Netanyahu a much-needed parliamentary cushion beyond his current razor-thin coalition. 

Herzog first had to convince his own highly-reluctant party of the need to join its rival Netanyahu—and if peace was about to break out, how could they refuse? For about 48 hours it seemed like Herzog was indeed about to announce his decision to join the coalition, face the battle in his party, and become Israel's foreign minister.

Then something else happened. Rather than appointing Herzog as foreign minister, Netanyahu is now poised to bring back Avigdor Lieberman, a former foreign minister and Israel's least diplomatic politician. Lieberman won't be returning to diplomacy, however. Instead, he will get a significantly more powerful position, second only to the prime minister: minister of defense. In response, current Minister of Defense Moshe Ya’alon today resigned from the cabinet and the Knesset, refusing to take another cabinet position. He gave a scathing speech, saying that "[E]xtremist and dangerous forces have taken over Israel and the Likud movement."

In what can only be considered brilliant politicking—and reckless policy—Netanyahu jettisoned Ya’alon and Herzog in favor of his former associate and bitter personal rival, Lieberman.

In what can only be considered brilliant politicking—and reckless policy—Netanyahu jettisoned Ya’alon and Herzog in favor of his former associate and bitter personal rival, Lieberman. Herzog is left wounded and humiliated, played for a fool—the gravest sin in Israeli political culture. Netanyahu finds himself at the helm of an enlarged coalition (Lieberman brings with him five members of Knesset, after one member of his faction left the party today in protest of the move), safer from parliamentary shocks and from attacks from the right (the whole right wing is now inside the coalition. Lieberman will still likely criticize Netanyahu from within the government, but not quite as fiercely). 

A cynics’ cynic

Lieberman's pending appointment has been met with astonishment by the opposition in Israel, by many in the military which he will oversee, and indeed here in Washington—and with good reason.

Just these past few months, Lieberman has viciously attacked both Netanyahu and the military brass for what he claimed was a weak response to terrorist attacks. In but one example of many, Lieberman came to the defense of a soldier who the Israel Defense Forces (IDF) had decided to prosecute for killing a Palestinian assailant who had already been thoroughly subdued. The contrast to current Minister of Defense Moshe Ya’alon is striking: Ya’alon defended the military's decision and stressed the importance of ethical norms and of rules of engagement in the military. Ya’alon is very right wing on the Palestinian issue, but he has consistently shown an honorable stance in the face of attacks on democratic norms. 

Lieberman is ostensibly less right-wing on the Palestinian issue—sometimes. Though he is a settler himself, he has endorsed a two-state solution in very general theory, noting he would even move if peace necessitated it. His endorsement, however, has always been couched in the toughest language possible and in utter mistrust of Palestinian intentions or the chances of peace ever materializing. On the niceties of democratic norms, including military law, he is a cynics' cynic. Benny Begin, another former Likud minister and an avowed hawk, has called Lieberman's appointment “delirious.”

As minister of defense, these positions will be highly consequential. Not only will he be in charge of the military brass and its promotion, but he will have statutory authority over many affairs in the West Bank, which is under military rule. Any attempt to improve the daily lives of Palestinians (such as a project just announced to streamline checkpoints for Palestinians) will be under his purview. His open calls to bring down Hamas through a ground invasion of Gaza if there is another round of fighting with Hamas—voiced even while he was a cabinet member during the last round of fighting—will now carry the weight of the minister of defense.

What was Herzog thinking? 

For the past year, since Netanyahu formed his fourth government, Herzog had denied time and again that he was aiming to join Netanyahu rather than replace him. He bemoaned the cynicism of those who simply would not believe him. This week the masks came off. Negotiations between the sides were accelerated and Herzog began a difficult intra-party fight to justify such a move. "National unity" governments are quite common in Israel, starting with the emergency cabinet of 1967, on the eve of the Six-Day War, when a sense of imminent doom swept the country. 

These governments, however, are usually justified by either an acute crisis, like in 1967, or in order to resolve a political deadlock, such as between Shimon Peres' Labor and Yitzhak Shamir's Likud in 1984. Peres and Shamir even "rotated" the post of prime minister. Though the government was incapable of any meaningful diplomatic advances, on which it was divided, it succeeded in tackling hugely important challenges in the economy—bringing inflation down from an annual rate of over 444 percent (not a typo) in 1984, and in defense—extricating Israel from most of Lebanon, following the first Israeli Lebanon War. 

What would be the logic this time? Herzog was promising three things to his party members: a host of portfolios (jobs and titles but also influence on a range of domestic policy issues); a veto on some aspects of policy which Labor finds most damaging, including remote settlement construction and legislation seen as limiting democratic discourse in Israel; and a leading role in any negotiations with the Palestinians, staring with the French peace conference. 

The jobs for Labor would have been real. A veto on policy could have been important—Tzipi Livni, Herzog's non-Labor partner in the Zionist Union, played a crucial role in protecting democratic norms as minister of justice in Netanyahu's previous government. 

On peace, however, Herzog was offering fool's gold. Put it this way: if you think Herzog would have real autonomy to run negotiations with the Palestinians while Netanyahu is prime minister, I have two suggestions. First, ask Tzipi Livni, who had that exact task in the previous government and was accompanied to every negotiation by Netanyahu’s personal lawyer, Yitzhak Molcho. Livni, incidentally, was strongly opposed to joining Netanyahu this time around. 

Second, I have some great real-estate in a swamp in Florida I'd like to discuss with you.

Herzog had a political rationale as well. He is a natural minister and backroom politician: smart, hardworking and prone to pragmatic compromises. He is not a natural public politician. As Leader of the Opposition he has wowed no one with his charisma or ability to stand up to Netanyahu and offer a bold alternative. Better to be in the halls of power than in the open arena. With the prospects of a fierce leadership challenge in his own Labor Party, moreover, he would have bolstered his bona fides as a national leader and therefore give himself a bit more time—the most a politician in Israel can really hope for. 

If there was a political benefit to Herzog personally, the outlook for his Labor Party would have been dismal.

If there was a political benefit to Herzog personally, the outlook for his Labor Party would have been dismal. Having joined Netanyahu, it would have been very hard to present the party as an alternative to his rule. 

What now?

Netanyahu can now feel slightly more secure in his coalition, though once again at the mercy of the mercurial Lieberman. Lieberman will enjoy a powerful post that usually bestows its occupant with new popularity in Israel (the converse is true of the finance ministry). Finance Minister Moshe Kahlon will enjoy a wider coalition to pass his domestic legislation and budget; indeed he'd been pushing for enlarging the coalition since it was formed. 

In the opposition, Herzog is weaker than ever. After being led on by Netanyahu for months, breaking his own word on the negotiations and then losing his gamble, he is severely exposed to challenges within Labor. His party's image has taken a serious hit as well.

Herzog's weakness will allow others in the opposition to claim the mantle of alternative to Netanyahu. Already, Yair Lapid’s centrist Yesh Atid party is the main beneficiary, but others may emerge as well, especially from the ranks of former generals like Gabi Ashkenazi. 

Most importantly, Israel's actual policy may be affected significantly by this move. Of all the governmental posts, defense is the one that has the most effect on the crucial questions of security for Israelis (and on the daily lives of Palestinians). Instead of grand peace plans Herzog was selling, Netanyahu's political brilliance has wrought one of the most hardline governments Israel has ever had.

In his wide-ranging interview with The New York Times, Republican presidential nominee Donald J. Trump stressed the importance of fighting ISIS while declaring “we are going to take care of this country first before we worry about everybody else in the world.” For counterterrorism (and I would argue for security in general), such thinking is dangerously wrong-headed: Fighting ISIS and stopping other foreign terrorist threats to the U.S. homeland requires close alliances and deep engagement abroad.

Allies may also have better access to a terrorist stronghold due to geography or historic ties. Saudi Arabia, Turkey, and Jordan are within easy bombing range of ISIS’ core: the U.S. homeland is not. Although military action against ISIS’ core in Iraq and Syria is vital, it is often quiet global intelligence cooperation that does much of the day-to-day counterterrorism lifting. Given the geographic span of ISIS operations, it is not realistic for the United States to have strong unilateral capabilities in every possible country where the terrorists might operate and use as a base for anti-U.S. operations. Foreign governments fill this gap, acting as a force multiplier for the United States. Shortly after 9/11, the United States was working with over 100 countries on counterterrorism; several years into the war on terror a senior CIA official testified that virtually every capture or killing of a suspected terrorist outside Iraq involved at least some help from a foreign intelligence service. 

Many allies have skilled intelligence services, and they also use their police and their domestic intelligence services to gather information. These services of course know local languages and are culturally aware. They can also take advantage of the law in their efforts to disrupt terrorism: Terrorism, after all, is a crime. Allies, particularly less savory ones, use a government’s coercive power as well. Although people automatically think torture, governments at times threaten to jail a relative of a suspected terrorist or withhold a business permit or the right to attend university. These seemingly mundane threats are something that the United States cannot do outside its own borders. 

Many of the most basic homeland security tasks do not begin or end with the homeland.

Given these advantages, the primary role of U.S. intelligence is to cajole and strengthen allies, not replace them. The United States might provide technical assistance, as many U.S. allies are far weaker in this area. In addition, U.S. intelligence often acts as a conductor of global liaison services. In 2010, al-Qaida of the Arabian Peninsula tried to bomb two cargo planes as they approached the United States. Efforts to disrupt the plot involved not only the United States and Yemen, but also the countries in transit, including Qatar, the United Arab Emirates, Germany, and the United Kingdom. And Saudi Arabia provided a key intelligence tip. 

Many of the most basic homeland security tasks do not begin or end with the homeland. Foreign governments provide information on terrorist suspects, and there is considerable cooperation on those who might travel to the United States. Much of the screening to hinder terrorist travel and operations is done “over there,” not in the United States.

Our world is too small, and terrorists too global, to think of U.S. security narrowly. If we want to fight ISIS and other foes, we need allies. That doesn’t mean we should do whatever our allies want or support them unconditionally. But we must recognize that if we expect them to help America fight its enemies, we must stand by them as well.

What a way to start the new year. Decades of Saudi-Iranian tensions reached a new high this past week. The cycle of reactions to Riyadh’s execution of prominent Shiite cleric Nimr al-Nimr on January 2 is a reminder of how the Saudis, and their Iranian rivals, have viewed and used sectarianism throughout the tumultuous period since 2011.

Al-Nimr was arrested in 2012 and subsequently sentenced to death for allegedly "seeking ‘foreign meddling’ in Saudi Arabia, ‘disobeying’ its rulers and taking up arms against the security forces." The arrest was meant not merely as a signal to Tehran, but at least as much to Saudi Arabia’s own Shiite minority. Shiites comprise as much as 20 percent of the Saudi population, and are concentrated in the oil-rich Eastern Province—and the community has regularly erupted in protests against its economic and political marginalization. In 2011, amid the Arab Spring uprisings in majority-Shiite Bahrain, Saudi Shiites also demonstrated for the release of long-held prisoners, and Saudi forces shot and killed several Shia in the streets.

Riyadh’s decision to carry out the death sentence was greeted with demonstrations in Iran and attacks on Saudi diplomatic facilities. This Iranian reaction must have been calculated, as al-Nimr has been on “death row” for a very long time. In response, Saudi Arabia quickly cut ties with its longtime geopolitical foe and urged fellow Sunni governments to follow suit. So far, Bahrain and Sudan have also cut off relations, and both Qatar and the UAE have downgraded them. 

Governments on both sides of the Sunni-Shiite divide found a sectarian narrative useful in rallying their populations and in justifying their actions in response to the 2011 Arab uprisings. The sectarian narrative has helped the parties in this larger regional power struggle mobilize support by playing up the sectarian dimension of protests in Bahrain, the Assad regime’s crackdown in Syria, and the breakdown of inclusive politics in Iraq. Likewise, many Sunni-led countries have found sectarian rhetoric an effective way to rally Sunni citizens, intimidate their own Shiite populations, and to justify crackdowns on dissent. 

Governments on both sides of the Sunni-Shiite divide found a sectarian narrative useful in rallying their populations and in justifying their actions in response to the 2011 Arab uprisings.

Last April, I wrote that Iran was likely to escalate its asymmetric efforts to destabilize Arab politics by exploiting the cracks within Arab societies. They have done so, and it is a form of escalation the Saudis are ill-equipped to match. Last summer, I suggested that the Sunni Arab states could defend best against this Iranian subversion by tamping down sectarian tensions and working to heal the rifts within their own societies through inclusive political and economic policies. So far, I have not seen much effort from the Arab Gulf states in that direction—instead, they have doubled down on divisive sectarianism in Yemen and elsewhere. As this escalatory spiral advances, civilians will pay the price. 

Some are portraying the decision to execute al-Nimr as a negative Saudi response to Iranian efforts at rapprochement over the last few weeks. I do not necessarily see it that way, because the Iranians have done as much as the Gulf Cooperation Council (GCC) states to provoke and exploit tensions between the two in recent times. That notwithstanding, there is no question this execution will inflame sectarian tensions in the Gulf and Iraq, as well as present the Islamic State with new opportunities. 

It has been clear for some time that the U.S. focus on the threat from the so-called Islamic State is simply not matched by the Saudis, who are far more concerned about Iran and Shiite expansionism than by this violent extremist Sunni group in their neighborhood. As such, the execution and ensuing crisis brings the clash of U.S. and Saudi interests into sharp relief and has the potential to become an inflection point in regional affairs – not necessarily because of the way the Saudi and Iranian governments choose to play, but because of how others might react.

For example, Iraqi Prime Minister Haider al-Abadi quickly and publicly condemned the execution. The execution—and the inevitable crackdown on Shiite protests in Qatif—might increase pressure on Abadi from Shiites in Iraq (and from Iran) to demonstrate sectarian preferences in his rhetoric and policy. That could prevent him from moving forward on steps Washington has been pushing to bring Iraqi Sunnis back into the political fold. This easily could threaten the anti-Islamic State campaign in Iraq, since it relies on Sunnis in Ramadi, Mosul, and elsewhere turning away from Islamic State and back toward the Iraqi state. Iraqi counterterrorism forces have taken much of Ramadi, but they cannot hold it without local Sunni support.

Increased Islamic State influence in the Arabian Peninsula would certainly challenge the Saudi government and prompt a renewed securitization of domestic policy.

The Islamic State worked hard to stoke sectarian tensions within the Gulf states over the past year, carrying out attacks on Shiite mosques in Saudi Arabia and Kuwait. The GCC leaders were not drawn in at that stage, instead expressing solidarity with their Shiite compatriots. But this time, a Sunni Gulf government is taking steps that exacerbate sectarian tensions—and that could very easily push the Islamic State to take up the issue again by attempting more such attacks. Increased Islamic State influence in the Arabian Peninsula would certainly challenge the Saudi government and prompt a renewed securitization of domestic policy. It would be an ironic outcome of a Saudi move—47 executions, mostly of Sunni extremists—that was intended to deter ISIS sympathizers. At a moment when low oil prices and a tightened financial future constrain their capacity to coopt a large, underemployed, youthful populace, this is not a recipe for stability.

The possibility that ISIS will gain from this crisis illustrates the problem with governments self-interestedly wielding that sectarian narrative is that it becomes a self-fulfilling prophecy, and it actually increases the incentive on both sides of the sectarian divide to escalate their real power competition, both directly and through proxies. Today, that narrative of sectarian conflict is far more than rhetoric in Iraq and Syria, where a true intercommunal conflict is underway. 

More immediately, the ripple effects of al-Nimr’s execution spotlight American policy dilemmas in the region. The escalation in sectarian conflict threatens the nascent Syrian peace process. It increases the Islamic State’s scope for action there, threatens the political dimension of the anti-Islamic State strategy in Iraq, and incentivizes Sunni extremism in the Arabian Peninsula. It pushes the Yemen war further from resolution as well, leaving al-Qaida in the Arabian Peninsula (AQAP) with room to grow and plan attacks against the American homeland. And it puts the United States into a very tight spot as it continues diplomatic dialogue with Iran in the wake of the nuclear agreement. Given this beginning, 2016 looks to be an even tougher year for the United States in the Middle East than 2015.

In their recent blog for Social Mobility Memos, Brad Wilcox, Robert Lerman, and Joseph Price make a convincing case that a stable family structure is an important factor in increased social mobility, higher economic growth, and less poverty over time.

The interesting question is: what lies behind this relationship? Why is a rise (or a smaller decline) in the proportion of married families associated, for example, with higher growth in average family incomes or a decline in poverty? The authors suggest a number of reasons, including the positive effects of marriage for children, less crime, men’s engagement in work, and income pooling. Of these, however, income pooling is by far the most important. Individual earnings have increased very little, if at all, over the past three or four decades, so the only way for families to get ahead was to add a second earner to the household. This is only possible within marriage or some other type of income pooling arrangement like cohabitation. Marriage here is the means: income pooling is the end.

How do we encourage more people to share incomes and expenses? There are no easy answers. Wilcox and his co-authors favor reducing marriage penalties in tax and benefit programs, expanding training and apprenticeship programs, limiting divorces in cases where reconciliation is still possible, and civic efforts to convince young people to follow what I and others have called the “success sequence.” All of these ideas are fine in principle. The question is how much difference they can make in practice. Previous efforts have had at best modest results, as a number of articles in the recent issue of the Brookings-Princeton journal The Future of Children point out.      

Our success sequence, which Wilcox wants to use as the basis for a pro-marriage civic campaign, requires teens and young adults to complete their education, get established in a job, and to delay childbearing until after they are married. The message is the right one.

The problem is that many young adults are having children before marriage. Why? Early marriage is not compatible, in their view, with the need for extended education and training. They also want to spend longer finding the best life partner. These are good reasons to delay marriage. But pregnancies and births still occur, with or without marriage. For better or worse, our culture now tolerates, and often glamorizes, multiple relationships, including premarital sex and unwed parenting. This makes bringing back the success sequence difficult.

Our best bet is to help teens and young adults avoid having a child until they have completed their education, found a steady job, and most importantly, a stable partner with whom they want to raise children, and with whom they can pool their income. In many cases this means marriage; but not in all. The bottom line: teens and young adults need more access and better education and counselling on birth control, especially little-used but highly effective forms as the IUD and the implant. Contraception, not marriage, is where we should be focusing our attention.

Employment among lower-income men has declined by 11 percent since 1980 and has remained flat among lower-income women. Men and women in the top and middle of the income distribution, on the other hand, have been working as much or more since 1980, creating a growing “work gap” in labor market income between haves and have-nots.   

This paper simulates the effect of five labor market interventions (higher high school graduation rate, minimum wage increases, maintaining full employment, seeing all household heads work full time, and virtual marriages between single mothers and unattached men) on the average incomes of the poorest one-third of American households. They find that the most effective way to increase average incomes of the poorest Americans would be for household heads to work full time, whereas the least effective intervention would be increasing education.

In terms of actual impact on incomes, the simulation of all household heads working full time at their expected wage increased average household earnings by 54 percent from a baseline of $12,415 to $19,163. The research also suggests that even if all household heads worked just some—at expected wages or hours—average earnings would still increase by 16 percent.

The least effective simulation was increasing the high school graduation rate to 90 percent and having half of those “newly” graduated go on to receive some form of post-secondary education. The authors note that the low impact of increasing education on mobility is likely because only one in six of bottom-third adults live in a household in which someone gains a high school degree via the intervention.

Because single parents are disproportionately represented among low-income families, Sawhill and coauthors also explored the impact of adding a second earner to single-parent families through a simulation that pairs low-income, single-mother household heads with demographically similar but unrelated men. That simulation increased the average household earnings of the bottom-third only modestly, by $508, or about 4 percent.

Efforts to increase employment among heads of the poorest households must take into consideration why those household heads aren’t working, they note. According to data from the 2015 Census, the most cited reason for women not working is “taking care of home and family” and for men it is being “ill or disabled.”
