Justin Wolfers’ column titled “Debunking the Easterlin Paradox, Again” dismisses Richard Easterlin’s work as just plain wrong. I argue here, as I have elsewhere, that where you come out on the Easterlin paradox depends on the happiness question (and therefore the definition of happiness) that you use, as well as the sample of countries and the period of time.

Richard Easterlin finds no clear country-by-country relationship between average per capita GDP and life satisfaction (among wealthy countries), despite a clear relationship between income and happiness at the individual level within countries. Easterlin also found – and continues to find, based on methods different from Wolfers’ – an absence of a relationship between life satisfaction and long-term changes in GDP per capita.

Different well-being questions measure different dimensions of “happiness”, and, in turn, they correlate differently with income (something they themselves show at the end of their last paper, and admit that the relationship between income and well-being is complex). The best possible life question – which Justin Wolfers and Betsey Stevenson primarily use in the first work, and also in the second – asks respondents to compare their life today to the best possible life they can imagine for themselves. This introduces a relative component, and, not surprisingly, the question correlates most closely with income of all of the available subjective well-being questions. Life satisfaction, which they use in the second work, also correlates with income more than open-ended happiness, life purpose or affect questions, but not as closely as the best possible life question.

Wolfers and Stevenson used the most recent and extensive sample of countries available from the Gallup World Poll, and, as the measure of “happiness”, the best possible life question therein, and challenged the Easterlin paradox. In more recent work, with Stevenson and Dan Sacks (2010), referenced in this blog, the authors look at the relationship between life satisfaction and economic growth, based on the World Values survey and GDP levels and the best possible life question, based on the Gallup World Poll. They isolate a clear relationship between life satisfaction and GDP levels, and their statistical analysis is spot on.

Recent studies by Kahneman and Deaton (2010), and Diener and colleagues (2010), for example, find that happiness in a life evaluation sense (as measured by the best possible life question) correlates much more closely with income than does happiness in a life experience sense (as measured by affect or more open ended happiness questions). This holds within the United States (Kahneman and Deaton) and across countries (Diener et al.).

My own work on Latin America, with Soumya Chattopadhyay and Mario Picon, tested various questions against each other and finds a similar difference in correlation, with affect and life purpose questions having the least correlation with income and the best possible life question the most. My work on happiness in Afghanistan found that Afghans were happier than the world average (on par with Latin Americans) as measured by an open ended happiness question, and 20 percent more likely to smile in a day than Cubans. Yet they scored much lower than the world average on the best possible life question. This is not a surprise. While naturally cheerful and able to make the best of their lot, the Afghans also know that the best possible life is outside Afghanistan.

Thus the conclusions that one draws on whether there is an Easterlin paradox or not in part rest on the definition of happiness, and therefore the question that is used as the basis of analysis. Wolfers and co-authors find a clear relationship between GDP levels and life satisfaction and best possible life – clearly important dimensions of well-being. Yet in the same paper they find much less clear relationships when they use happiness, affect and life purpose questions.  

There is also the question of the sample of countries, and whether one is examining cross section or time series data. The most recent debate with Easterlin is about the trends over time rather than cross-sectional patterns. Dropping the transition economies, as Easterlin does, may be a mistake, as Wolfers contends. But it is also important to recognize the extent to which including a large sample of countries that experienced unprecedented economic collapse and associated drops in happiness alters the slope in the cross-country income-happiness relationship (making it steeper). Wolfers also criticizes Easterlin for relying on financial satisfaction data for his Latin American time series sample (because there is not enough life satisfaction data); financial satisfaction correlates closely, but not perfectly, with life satisfaction. Easterlin’s technique allows for the inclusion of a much larger sample of middle income developing countries, a sample of countries that one can imagine is very important to the growth and happiness debate. Wolfers and co-authors use far fewer Latin American countries because comparable life satisfaction data is limited. Either approach is plausible and, as with all work with limited data, is not perfect. But I would not go as far as calling one or the other “plain wrong”.

Finally, there is the simpler question of giving credit where credit is due. We would not be having this debate, nor would we have a host of analysis on well-being beyond what is measured by income, had Easterlin not triggered our thinking on this with his original study of happiness and income over three decades ago (and his patient and thoughtful mentoring of many economists since then). In the big picture of things, Easterlin had the idea.

Justin Wolfers, professor of Economics and Public Policy at the University of Michigan, re-joins Brookings, Vice President and Economic Studies Co-Director Karen Dynan announced today.  Wolfers was a visiting fellow from 2010-2011.

A world-renowned empirical economist, Wolfers will continue in his role as co-editor, along with David Romer of the University of California, of the Brookings Papers on Economic Activity (BPEA), the flagship economic journal of the Institution.  He will continue his focus on labor economics, macroeconomics, political economy, economics of the family, social policy, law and economics, public economics, and behavioral economics. His appointment as senior fellow will last 13 months.

Wolfers is also a research associate with the National Bureau for Economic Research, a research affiliate of the Centre for Economic Policy Research in London, a research fellow of the German Institute for the Study of Labor, and a senior scientist for Gallup, among other affiliations. He is a contributor for Bloomberg View, NPR Marketplace, and the Freakonomics website and was named one of the 13 top young economists to watch by the New York Times.  Wolfers did his undergraduate work at the University of Sydney, Australia and received his Master’s and Ph.D. in Economics from Harvard University.  He is a dual Australian-U.S. national and was once an apprentice to a bookie which led to his interest in prediction markets. 

“We are pleased to re-welcome Justin back to Economic Studies,” said Dynan. “His work continues to challenge the conventional wisdom, and we look forward to collaborating with him once again.” 

“Justin is outstanding at communicating economic ideas to a wide audience, as evidenced by his regular writings for media as well as his large social media presence,” added Ted Gayer, co-director of Economic Studies.

“I have enormous affection for the Brookings Institution, which provides not only a home for deep scholarly research, but also an unmatched platform for engaging the policy debate,” said Wolfers.  “The Economic Studies program has a rich history of being the go-to place for policymakers, and I look forward to coming back and engaging in debate with my colleagues there.”

Thursday, South Africa’s highest court found President Zuma guilty of violating the constitution as he refused to reimburse the large sum of money spent on improvements to his personal home. Between 2010 and 2014, the home located in the president’s rural hometown of Nkandla received improvement which cost an estimated $23 million. The improvements include a chicken coop, an amphitheater, a swimming pool, and a helipad. President Zuma has stated that the improvements were necessary to ensure his security and should consequently be paid for with taxpayers’ money. In 2014, public prosecutor Thuli Madonsela ruled that the president should repay part of the taxpayers’ money spent on the improvements of his personal home. In refusing to do so, he violated the country’s constitution “by not complying with a decision by the public protector, the national watchdog.” The court has given the National Treasury 60 days to determine the sum the president must repay. The opposition has stated that they will seek Zuma’s impeachment.

In other South African news, this week, the rand strengthen against the U.S. dollar and reached its highest value since December 8, 2015, the day before President Zuma fired former Finance Minister Nhlanla Nene. The strengthening of the rand was coupled with the strengthening of other Emerging Markets currencies. This hike follows the statement from Federal Reserve Chair Janey Yellen, reiterating the importance to raise U.S. interest rates cautiously, amid risks in the global economy. Investors—weighting prospects of higher U.S. borrowing costs—were holding off in acquiring emerging-market assets.

This week, 17 Angolan activists were sentenced to jail time for rebellion against the government of Jose Eduardo dos Santos. The sentences ranged from two years to eight and a half years. Last June, the activists were arrested during a book club meeting focusing on Gene Sharp’s book titled From Dictatorship to Democracy: A Conceptual Framework for Liberation—a book on nonviolence and resistance to repressive regimes. Monday, the activists were charged and sentenced with acts of rebellion, planning mass action of civil disobedience, and producing fake passports, among other charges. Amnesty International has accused the Angolan court of wrongfully convicting the activists and using the judicial system to “silence dissenting views.”

Later in the week, in response to the jailing of the young activists, the Portuguese branch of hacking group Anonymous claimed the shutdown of 20 government websites, including that of the Ministry of Education and the Ministry of Labor and Social Security, among others. In a Facebook post claiming the attack, the group states, “The real criminals are outside, defended by the capitalist system that increasingly spreads in the minds of the weak.” The functionality of the websites has been restored.  

On Monday, March 28, the U.S. Millennium Challenge Corporation (MCC) withdrew $472 million in aid from the government of Tanzania after the result of the last weekend’s disputed presidential election rerun in the semi-autonomous archipelago of Zanzibar was announced. Incumbent President Ali Mohamed Shein of the ruling Chama Cha Mapinduzi party was declared the winner with 91.4 percent of the vote. However, the rerun was boycotted by the opposition Civic United Front party over the cancellation of last October’s election by the Zanzibar Electoral Commission. The commission claimed the October poll was fraudulent, while the opposition says the allegations of fraud were fabricated to thwart a victory by their candidate.

The MCC was planning a number of power and infrastructure projects in Tanzania, but its development assistance programming is conditional upon beneficiaries meeting certain standards of good governance. The MCC’s board of directors held a vote on Monday, in which they determined that Tanzania was no longer eligible to partner with the MCC given the election outcome. Although the loss of the MCC partnership is a sizable blow to the Tanzanian government, the Tanzanian finance minister appeared optimistic that the power projects would continue despite the MCC’s decision, as he stated: “We weren’t surprised at all because we were prepared for whatever the outcome. We will implement those projects using local sources of fund and the support of from other development partners.” Meanwhile, 10 out of the country’s 14 key western donors withdrew general budget support to Tanzania over the contested election.
