Shekhar Aiyar, Christian Ebeke, Xiaobo Shao, IMF: The Euro Area Workforce is Aging, Costing Growth. The euro area’s population is expected to grow significantly older over the next couple of decades. This has two components. First, the number of retirees is set to grow compared to the people of working age (15–64) in the region. Second, and much less examined, the average age of people within the labor force will rise: the share of workers aged 55–64 is forecast to increase by a third, from 15 percent to 20 percent, over the next two decades. Aging will take a considerable toll on productivity growth over the medium- to long-term. Average total factor productivity growth in the euro area is forecast to be around 0.8 percent per year. This could be higher by a quarter—that is to say, total factor productivity could increase to about one percent per year—if we shut down the effect of workforce aging. The burden of workforce aging will fall unequally across euro area member states. Worryingly, some of the largest adverse effects on productivity will fall on countries that can least afford it, such as Greece, Spain, Portugal, and Italy.
David Halpern, BoE: It’s time to bring more realistic models of human behaviour into economic policy and regulation. Behaviour science has had major impacts on policy in recent years. Introducing a more realistic model of human behaviour – to replace the ‘rational’ utility-maximizer – has enabled policymakers to boost savings; increase tax payments; encourage healthier choices; reduce energy consumption; boost educational attendance; reduce crime; and increase charitable giving. But there remain important areas where its potential has yet to be realised, including macroeconomic policy and large areas of regulatory practice. Businesses, consumers, and even regulators are subject to similar systematic biases to other humans. These include overconfidence; being overly influenced by what others are doing; and being influenced by irrelevant information. The good news is that behavioural science offers the prospect of helping regulators address some of their most pressing issues. This includes: anticipating and addressing ‘animal spirits’ that drive bubbles or sentiment-driven slowdowns; reducing corrupt market practices; and encouraging financial products that are comprehensible to humans.
Rasmus Landersø, James J. Heckman, NBER: The Scandinavian Fantasy: The Sources of Intergenerational Mobility in Denmark and the U.S. This paper examines the sources of differences in social mobility between the U.S. and Denmark. Measured by income mobility, Denmark is a more mobile society, but not when measured by educational mobility. There are pronounced nonlinearities in income and educational mobility in both countries. Greater Danish income mobility is largely a consequence of redistributional tax, transfer, and wage compression policies. While Danish social policies for children produce more favorable cognitive test scores for disadvantaged children, these do not translate into more favorable educational outcomes, partly because of disincentives to acquire education arising from the redistributional policies that increase income mobility.
Jeff Gou, Washington Post: The clearest proof yet that your job is killing you. For decades now, the modern worker has been urged to slow down, chill out, de-stress. Doctors link long shifts and on-the-job anxiety to high blood pressure, heart disease, depression and stroke. Yet, so far, the connection between job strain and bad health has mostly been correlational. Recently, economists at Purdue and the University of Copenhagen made a clever attempt to clear up the question. They looked at Danish manufacturing companies where overseas sales increased unexpectedly because of changes in foreign demand or transportation costs between 1996 and 2006. These constituted a set of natural experiments. At firms where exports spiked, there was suddenly a lot more work to do, a lot more things to sell. Researchers found that women at companies where there was an export boom were subsequently more likely to be treated for severe depression, and more likely to take prescription medication for heart attack or stroke. For both men and women, there was also an increase in severe on-the-job injuries.
Roland G. Fryer, Jr, NBER: An Empirical Analysis of Racial Differences in Police Use of Force. This paper explores racial differences in police use of force. On non-lethal uses of force, blacks and Hispanics are more than fifty percent more likely to experience some form of force in interactions with police. Adding controls that account for important context and civilian behavior reduces, but cannot fully explain, these disparities. On the most extreme use of force – officer-involved shootings – we find no racial differences in either the raw data or when contextual factors are taken into account. We argue that the patterns in the data are consistent with a model in which police officers are utility maximizers, a fraction of which have a preference for discrimination, who incur relatively high expected costs of officer-involved shootings.
Bjorn Lomborg, US Today: Organic food is great business, but a bad investment. An organic label sends our skepticism and good sense out the window. Consumers in one study were given two sets of absolutely identical food items, with one set marked “organic” and one not. They declared the food they believed to be “organic” to be lower in calories and more nutritious, and were willing to pay 16% to 23% more. It’s called the “health halo” effect. Organic food has become the fastest-growing sector of the U.S. food industry, with sales that increase by double digits annually. But organics are not better for your health, worse for nature and the planet, and terrible for the world’s poor. What it boils down to is the world’s richest people spending their cash to support less efficient farming practices, to feel better about their choices.

Yuliya Demyanyk et al., Cleveland FED: Does Fiscal Stimulus Work When Recessions Are Caused by Too Much Private Debt? We argue that fiscal stimulus funded by public debt is effective for increasing economic activity and employment even in recessions that are caused by overborrowing in the private sector. We analyze the impact of government spending on local economies between 2007 and 2009 and find evidence that the fiscal multiplier is higher in geographical areas characterized by higher individual household debt. The higher multiplier in those areas might be attributed to a direct increase in both household consumption and local economic slack.
George J. Borjas, The Politico: The Case for Extreme Immigrant Vetting. It’s a practice as American as apple pie—and for good reason. In his major foreign policy speech earlier this week, Donald Trump explained how he would expand the “ideological” vetting of immigrants who want to come to the United States. “The time is overdue to develop a new screening test for the threats we face today,” he said. “I call it extreme vetting. As with practically all of Trump’s policy statements, the over-the-top commentary came swiftly. Over at the Washington Post an opinionator opined that Trump’s ideas were crazier than crazy. At MSNBC a commentator commented that “this is the single most un-American thing I have ever heard in my life.” If all those pundits had bothered to do just a couple of minutes of googling before reacting, they would have discovered that immigrant vetting, and even extreme immigrant vetting, has a very long tradition in American history. Since before the founding even, U.S. policies about whom the country chooses to welcome and reject have changed in response to changing conditions. As early as 1645, the Massachusetts Bay Colony prohibited the entry of poor or indigent persons. By the early 20th century, the country was filtering out people who had “undesirable” traits, such as epileptics, alcoholics and polygamists.
Emily Breza, Supreet Kaur, Yogita Shamdasani, NBER: The Morale Effects of Pay Inequality. The idea that worker utility is affected by co-worker wages has potentially broad labor market implications. In a month-long experiment with Indian manufacturing workers, we randomize whether co-workers within production units receive the same flat daily wage or different wages (according to baseline productivity rank). For a given absolute wage, pay inequality reduces output and attendance by 0.24 standard deviations and 12%, respectively. These effects strengthen in later weeks. Pay disparity also lowers co-workers’ ability to cooperate in their self-interest. However, when workers can clearly observe productivity differences, pay inequality has no discernible effect on output, attendance, or group cohesion.
Stefan Pichler, Nicolas R. Ziebarth, NBER: The Pros and Cons of Sick Pay Schemes: Testing for Contagious Presenteeism and Noncontagious Absenteeism Behavior. This paper provides an analytical framework and uses data from the US and Germany to test for the existence of contagious presenteeism and negative externalities in sickness insurance schemes. The first part exploits high-frequency Google Flu data and the staggered implementation of U.S. sick leave reforms to show in a reduced-from framework that population-level influenza-like disease rates decrease after employees gain access to paid sick leave. Next, a simple theoretical framework provides evidence on the underlying behavioral mechanisms. The model theoretically decomposes overall behavioral labor supply adjustments ('moral hazard') into contagious presenteeism and noncontagious absenteeism behavior and derives testable conditions. The last part illustrates how to implement the model exploiting German sick pay reforms and administrative industry-level data on certified sick leave by diagnoses. It finds that the labor supply elasticity for contagious diseases is significantly smaller than for noncontagious diseases. Under the identifying assumptions of the model, in addition to the evidence from the U.S., this finding provides indirect evidence for the existence of contagious presenteeism.
Jonathan T. Rothwell, Gallup: Explaining Nationalist Political Views: The Case of Donald Trump. The 2016 US presidential nominee Donald Trump has broken with the policies of previous Republican Party presidents on trade, immigration, and war, in favor of a more nationalist and populist platform. Using detailed Gallup survey data for a large number of American adults, I analyze the individual and geographic factors that predict a higher probability of viewing Trump favorably and contrast the results with those found for other candidates. The results show mixed evidence that economic distress has motivated Trump support. His supporters are less educated and more likely to work in blue collar occupations, but they earn relative high household incomes, and living in areas more exposed to trade or immigration does not increase Trump support. There is stronger evidence that racial isolation and less strictly economic measures of social status, namely health and intergenerational mobility, are robustly predictive of more favorable views toward Trump, and these factors predict support for him but not other Republican presidential candidates.
Melvin Sanicas, Project Syndicate: Vaccines for an Aging Population. Thanks to child immunization programs, fewer children die each year from vaccine-preventable diseases. A similar, concentrated effort is now needed to produce similar benefits for adults, especially the elderly. By viewing vaccination as a lifelong priority, we can help people remain active and productive for as long as possible, benefiting them, their communities, and the world.

Greg Kaplan, Sam Schulhofer-Wohl, NBER: Inflation at the Household Level. We use scanner data to estimate inflation rates at the household level. Households' inflation rates are remarkably heterogeneous, with an interquartile range that varies between 6.2 and 9.0 percentage points on an annual basis. Most of the heterogeneity comes not from variation in broadly defined consumption bundles but from variation in prices paid for the same types of goods — a source of variation that previous research has not measured. The entire distribution of household inflation rates shifts in parallel with aggregate inflation. Deviations from aggregate inflation exhibit only slightly negative serial correlation within each household over time, implying that the difference between a household's price level and the aggregate price level is persistent. Together, the large cross-sectional dispersion and low serial correlation of household-level inflation rates mean that almost all of the variability in a household's inflation rate over time comes from variability in household-level prices relative to average prices for the same goods, not from variability in the aggregate inflation rate. We provide a characterization of the stochastic process for household inflation that can be used to calibrate models of household decisions.
Wolfgang Keller, Hâle Utar, NBER:International Trade and Job Polarization: Evidence at the Worker-Level. This paper examines the role of international trade for job polarization, the phenomenon in which employment for high- and low-wage occupations increases but mid-wage occupations decline. With employer-employee matched data on virtually all workers and firms in Denmark between 1999 and 2009, we use instrumental-variables techniques and a quasi-natural experiment to show that import competition is a major cause of job polarization. Import competition with China accounts for about 17% of the aggregate decline in mid-wage employment. Many mid-skill workers are pushed into low-wage service jobs while others move into high-wage jobs. The direction of movement, up or down, turns on the skill focus of workers’ education. Workers with vocational training for a service occupation can avoid moving into low-wage service jobs, and among them workers with information-technology education are far more likely to move into high-wage jobs than other workers.
Angus Deaton, Project Syndicate: Rethinking Robin Hood. Huge strides have undoubtedly been made in reducing global poverty, more through growth and globalization than through aid from abroad. While impressive and wholly welcome, poverty reduction has not come without a cost. The globalization that has rescued so many in poor countries has harmed some people in rich countries, as factories and jobs migrated to where labor is cheaper. This seemed to be an ethically acceptable price to pay, because those who were losing were already so much wealthier (and healthier) than those who were gaining. Globalization is less splendid for those who not only don’t reap its benefits, but suffer from its impact. We have long known that less-educated and lower-income Americans, for example, have seen little economic gain for four decades, and that the bottom end of the US labor market can be a brutal environment. But just how badly are these Americans suffering from globalization? Are they much better off than the Asians now working in the factories that used to be in their hometowns?
Jonas Helgertz, Kirk Scott, Christopher D. Smith,  IZA: Parents’ years in Sweden and children’s educational performance. This paper assesses the intergenerational effect of immigrant parents’ incorporation experiences, measured as time in Sweden, on the educational performance of their children, using full Swedish population registry data for 22 cohorts. Employing family fixed-effects, we examine final course grades and national standardized test scores in Swedish and math by parents’ country of origin. Results show a positive effect of parents’ time in Sweden on their children’s performance in Swedish, but not for math performance. These results demonstrate the importance of parents’ linguistic acculturation on their children’s educational performance.
OECD: Equations and Inequalities - Making Mathematics Accessible to All. More than ever, students need to engage with mathematical concepts, think quantitatively and analytically, and communicate using mathematics. All these skills are central to a young person’s preparedness to tackle problems that arise at work and in life beyond the classroom. But the reality is that many students are not familiar with basic mathematics concepts and, at school, only practice routine tasks that do not improve their ability to think quantitatively and solve real-life, complex problems. One way forward is to ensure that all students spend more “engaged” time learning core mathematics concepts and solving challenging mathematics tasks. The opportunity to learn mathematics content – the time students spend learning mathematics topics and practising maths tasks at school – can accurately predict mathematics literacy. Differences in students’ familiarity with mathematics concepts explain a substantial share of performance disparities in PISA between socio-economically advantaged and disadvantaged students. Widening access to mathematics content can raise average levels of achievement and, at the same time, reduce inequalities in education and in society at large.
Valerie Wilson, EPI: People of color will be a majority of the American working class in 2032. This estimate, based on long-term labor force projections from the Bureau of Labor Statistics and trends in college completion by race and ethnicity, is 11 years sooner than the Census Bureau projection for the overall U.S. population, which becomes “majority-minority” in 2043. Wage stagnation is a universal problem for the working class, regardless of race, ethnicity, or gender. This is an area of immense common ground, because in order to deal with class inequality (a cause of wage stagnation), we have to deal with racial disparities. At the same time, reducing racial inequality means also addressing class inequality.

Lawrence H. Summers: The economic consequences of a Trump win would be severe. What I find surprising is that US and global markets and financial policymakers seem much less sensitive to “Trump risk” than they are to “Brexit risk”. Options markets suggest only modestly elevated volatility in the period leading up to the presidential election. While every Fed watcher comments on the implications of Brexit for the central bank, few, if any, comment on the possible consequences of a victory for Mr Trump in November. Yet, as great as the risks of Brexit are to the British economy, I believe the risks to the US and global economies of Mr Trump’s election as president are far greater. If he is elected, I would expect a protracted recession to begin within 18 months. The damage would be felt far beyond the United States.
Chad Syverson, NBER: Challenges to Mismeasurement Explanations for the U.S. Productivity Slowdown. Labor productivity in the United States—defined as total output divided by total hours of labor—has been increasing for over a century and continues to increase today. However, its growth rate has fallen. One explanation for this phenomenon focuses on measurement difficulties, in particular the possibility that current tools for measuring economic growth do not fully capture recent advances in the goods and services associated with digital communications technology. Mismeasurement of the prices and quantities of digital goods and services cannot account for the decline in the growth of labor productivity.
Torben M. Andersen, Silvia Migali, IZA: Migrant Workers and the Welfare State. There is wide concern that migration flows may undermine the financial viability of generous welfare arrangements. The discussion focuses on welfare arrangements as attractors of migrants, suggesting that the issue does not pertain to migrant workers. However, this overlooks how welfare arrangements affect return-migration in case of social events like job loss. Importantly, migrants are shown to be self-selected in a way affecting both migration and return-migration. Two migration regimes prevail. In one, with relatively low benefits, unemployed workers return, while in the other some stay. Importantly, the stay or return migration decision is more sensitive to welfare generosity than the migration decision.
Umut Özek, David N. Figlio, NBER: Cross-Generational Differences in Educational Outcomes in the Second Great Wave of Immigration. We make use of a new data source – matched birth records and longitudinal student records in Florida – to study the degree to which student outcomes differ across successive immigrant generations. We find evidence suggesting that early-arriving first generation immigrants perform better than do second generation immigrants, and second generation immigrants perform better than third generation immigrants. Among first generation immigrants, the earlier the arrival, the better the students tend to perform. These patterns of findings hold for both Asian and Hispanic students, and suggest a general pattern of successively reduced achievement – beyond a transitional period for recent immigrants – in the generations following the generation that immigrated to the United States.
Bjørn Lomborg, Project Syndicate: The Evidence on Education Reforms. It is almost universally agreed that more education is good for society. But it turns out that some popular educational policies achieve very little, while others that are often overlooked can make a huge difference. Whether for Bangladesh or elsewhere, the real lessons to be taken away from this research is that we need to look past trendy policies like adding technology to classrooms. The key to educational progress is to focus on interventions backed by credible scientific evidence.
Chenkai Wu, Michelle C Odden, Gwenith G Fisher, Robert S Stawski, JECH: Association of retirement age with mortality: a population-based longitudinal study among older adults in the USA. On the basis of the Health and Retirement Study, 2956 participants who were working at baseline (1992) and completely retired during the follow-up period from 1992 to 2010 were included. Healthy retirees (n=1934) were defined as individuals who self-reported health was not an important reason to retire. Over the study period, 234 healthy and 262 unhealthy retirees died. Among healthy retirees, a 1-year older age at retirement was associated with an 11% lower risk of all-cause mortality (95% CI 8% to 15%), independent of a wide range of sociodemographic, lifestyle and health confounders. Similarly, unhealthy retirees (n=1022) had a lower all-cause mortality risk when retiring later (HR 0.91, 95% CI 0.88 to 0.94). None of the sociodemographic factors were found to modify the association of retirement age with all-cause mortality.
Efraim Benmelech, Esteban F. Klor, NBER: What Explains the Flow of Foreign Fighters to ISIS? This paper provides the first systematic analysis of the link between economic, political, and social conditions and the global phenomenon of ISIS foreign fighters. We find that poor economic conditions do not drive participation in ISIS. In contrast, the number of ISIS foreign fighters is positively correlated with a country's GDP per capita and Human Development Index (HDI). In fact, many foreign fighters originate from countries with high levels of economic development, low income inequality, and highly developed political institutions. Other factors that explain the number of ISIS foreign fighters are the size of a country's Muslim population and its ethnic homogeneity. Although we cannot directly determine why people join ISIS, our results suggest that the flow of foreign fighters to ISIS is driven not by economic or political conditions but rather by ideology and the difficulty of assimilation into homogeneous Western countries.

Gauti B. Eggertsson, Neil R. Mehrotra, Sanjay R. Singh, Lawrence H. Summers, NBER: A Contagious Malady? Open Economy Dimensions of Secular Stagnation. Conditions of secular stagnation - low interest rates, below target inflation, and sluggish output growth - characterize much of the global economy. We consider an overlapping generations, open economy model of secular stagnation, and examine the effect of capital flows on the transmission of stagnation. In a world with a low natural rate of interest, greater capital integration transmits recessions across countries as opposed to lower interest rates. In a global secular stagnation, expansionary fiscal policy carries positive spillovers implying gains from coordination, and fiscal policy is self-financing. Expansionary monetary policy, by contrast, is beggar-thy-neighbor with output gains in one country coming at the expense of the other. Similarly, we find that competitiveness policies including structural labor market reforms or neomercantilist trade policies are also beggar-thy-neighbor in a global secular stagnation.
Mikhail Golosov, Guido Menzio, Princeton University. Agency Business Cycles. We propose a new business cycle theory. Firms need to randomize over firing or keeping workers who have performed poorly in the past, in order to give them an ex-ante incentive to exert effort. Firms have an incentive to coordinate the outcome of their randomizations, as coordination allows them to load the firing probability on states of the world in which it is costlier for workers to become unemployed and, hence, allows them to reduce overall agency costs. In the unique equilibrium, firms use a sunspot to coordinate the randomization outcomes and the economy experiences endogenous and stochastic aggregate fluctuations.
Nicola Fuchs-Schündeln, Paolo Masella, VOX: Long-Lasting effects of socialist education: Evidence from the German Democratic Republic. There are strong links between the nature of education in a country and its political institutions, and an individual’s education can impact their lifetime labour market choices. This column examines how being educated under a socialist regime impacts individuals in a free labour market. Using data on students from East and West Germany in the 1970s, it finds that a socialist regime education led to a larger spread in labour market outcomes – more of these individuals were not employed, but conditional on being employed, had higher wages and a higher probability of achieving a professional status in the East.
Iliev R., Axelrod R., PubMed.gov:Does Causality Matter More Now? Increase in the Proportion of Causal Language in English Texts. The vast majority of the work on culture and cognition has focused on cross-cultural comparisons, largely ignoring the dynamic aspects of culture. In this article, we provide a diachronic analysis of causal cognition over time. We hypothesized that the increased role of education, science, and technology in Western societies should be accompanied by greater attention to causal connections. To test this hypothesis, we compared word frequencies in English texts from different time periods and found an increase in the use of causal language of about 40% over the past two centuries. The observed increase was not attributable to general language effects or to changing semantics of causal words. We also found that there was a consistent difference between the 19th and the 20th centuries, and that the increase happened mainly in the 20th century.
Ivan G. Lopez Cruz, Sebastian Galiani, Gustavo Torrens, VOX: Stirring up a hornets’ nest: Geographic distribution of crime. A large empirical literature has revealed the effects of preventative and punitive measures on crime. This column examines the effects of police deployment strategies, comparing geographically concentrated protection with evenly dispersed protection across a city. The results suggests that when considering changes in the geographic distribution of police forces, we should take into account the effects on house prices and on reallocation of the population, as well as the overall effect on crime in the entire city.
Tim Harford, The Undercover Economist, The odds are you won’t know when to quit. Do we tend to quit too soon or quit too late? Are we too stubborn or not determined enough? There has been much excitement recently around the idea of “grit” — a personality trait representing commitment to and enthusiasm for long-term goals, championed by psychologist Angela Duckworth. She argues, plausibly, that grit is more important than talent in predicting a successful life. The idea is appealing in principle but one must ask what Duckworth’s brief “grit” questionnaire is really measuring. While Duckworth’s work suggests that perseverance is vital, other psychological research suggests that we sometimes persevere when we should not. Nobel laureate Daniel Kahneman, with the late Amos Tversky, discovered a tendency called “loss aversion”. Loss aversion is a disproportionate dislike of losses relative to gains, and it can lead us to cling on pig-headedly to bad decisions because we hate to stop playing when we’re behind.

Atif Mian, Amir Sufi, NBER: Who Bears the Cost of Recessions? The Role of House Prices and Household Debt. This chapter reviews empirical estimates of differential income and consumption growth across individuals during recessions. Most existing studies examine the variation in income and consumption growth across individuals by sorting on ex ante or contemporaneous income or consumption levels. We build on this literature by showing that differential shocks to household net worth coming from elevated household debt and the collapse in house prices play an underappreciated role. Using zip codes in the United States as the unit of analysis, we show that the decline in numerous measures of consumption during the Great Recession was much larger in zip codes that experienced a sharp decline in housing net worth. In the years prior to the recession, these same zip codes saw high house price growth, a substantial expansion of debt by homeowners, and high consumption growth. We discuss what models seem most consistent with this striking pattern in the data, and we highlight the increasing body of macroeconomic evidence on the link between household debt and business cycles. Our main conclusion is that housing and household debt should play a larger role in models exploring the importance of household heterogeneity on macroeconomic outcomes and policies.

Roger Backhouse, Beatrice Cherrier, University of Birmingham: 'It's Computerization, Stupid!' The Spread of Computers and the Changing Roles of Theoretical and Applied Economics. This paper challenges the widely held notion that the developments in computing are sufficient to explain the recent turn to applied economics. Developments in computer hardware were undoubtedly important. Yet, economists' appropriation of the new techniques allowed by computerization were highly selective, and influenced by the development of software and ties with other scientific communities, by the availability of business and governmental data, by salesmanship to policy-makers, and by how epistemologically acceptable these approaches were made to other economists. In particular, theoretical work was not be transformed by computers the way it was in physics or biology. We conjecture that the most profound effect of the increased availability of computers may have been to challenge the demarcation between theory and applied work.

Tomi Kyyrä, Juha Tuomala, IZA: Does Experience Rating Reduce Disability Inflow? This study explores whether the experience rating of employers’ disability insurance premiums affects the inflow of older employees to disability benefits in Finland. To identify the causal effect of experience rating, we exploit a pension reform that extended the coverage of the experience-rated premiums. The results show that a new disability benefit claim can cause substantial cost to the former employer through an increased premium. Nonetheless, we find no evidence of the significant effects of experience rating on the disability inflow. The lack of the behavioral effects may be due to the complexity of experience rating calculations and/or limited employer awareness.

Scott E. Carrell, Mark Hoekstra, Elira Kuka, NBER: The Long-Run Effects of Disruptive Peers. A large and growing literature has documented the importance of peer effects in education. However, there is relatively little evidence on the long-run educational and labor market consequences of childhood peers. We examine this question by linking administrative data on elementary school students to subsequent test scores, college attendance and completion, and earnings. To distinguish the effect of peers from confounding factors, we exploit the population variation in the proportion of children from families linked to domestic violence, who were shown by Carrell and Hoekstra (2010, 2012) to disrupt contemporaneous behavior and learning. Results show that exposure to a disruptive peer in classes of 25 during elementary school reduces earnings at age 26 by 3 to 4 percent. We estimate that differential exposure to children linked to domestic violence explains 5 to 6 percent of the rich-poor earnings gap in our data, and that removing one disruptive peer from a classroom for one year would raise the present discounted value of classmates' future earnings by $100,000.

Mark Leonard, Project Syndicate: Last Man Standing. Much of modern geopolitics seems to be following the plot from Game of Thrones, with many countries under so much political and economic stress that their only hope is that their rivals collapse before they do. So their governments cling to power while exploiting rivals’ internal weaknesses. Russian President Vladimir Putin is the prime example. His recent campaigns in Syria and Ukraine may look like the actions of a geopolitical buccaneer. But the root of his adventurism is domestic weakness. Russia’s annexation of Crimea, for example, was in large part an attempt to provide Putin’s regime with renewed legitimacy following a winter of discontent, during which demonstrators took to the streets to protest his return to the presidency.

Greg Ip WSJ: It’s Not the Economy, Stupid. Social disarray or cohesion are not always driven by economic ups and downs, as the 1960s attest. Economics cannot really explain why rapid growth in living standards coincided with so much political upheaval, just as it cannot explain why long periods of stagnation, as Japan has endured since the 1990s, are met with relative equanimity. Economics can’t explain why Britons may leave the European Union when the preponderance of evidence is that membership has made them richer. There is no way to predict the effect of so many different forces on the political choices that voters make. And even if there were, you would probably still not predict the rise of Mr. Trump, who got where he is by breaking every rule of conventional political and economic wisdom. Ultimately, the best explanation may be that he isn’t the product of larger economic forces: he’s the product of Donald Trump.

Eileen Moery, Robert J. Calin-Jageman, Social Psychological and Personality Science (2016): Direct and Conceptual Replications of Eskine (2013). Organic Food Exposure Has Little to No Effect on Moral Judgments and Prosocial Behavior. Is there a dark side to organic food? Eskine reported that participants exposed to organic food became much more morally judgmental and much less prosocial relative to participants exposed to neutral or comfort foods. This research sparked tremendous media interest, but was based on one experiment with a small sample size. We report three attempts to replicate Eskine using samples conferring high power, preregistered analysis plans, and original materials. Across two direct replications and an online conceptual replication, we found that organic food exposure has little to no effect on moral. Mere exposure to organic food is probably not sufficient to substantially change moral behavior.

Kishore Mahbubani, Lawrence H. Summers, Foreign Affairs: The Fusion of Civilizations. The Case for Global Optimism. To put it simply, the great world civilizations, which used to have detached and separate identities, now have increasingly overlapping areas of commonality. Most people around the world now have the same aspirations as the Western middle classes: they want their children to get good educations, land good jobs, and live happy, productive lives as members of stable, peaceful communities. Instead of feeling depressed, the West should be celebrating its phenomenal success at injecting the key elements of its worldview into other great civilizations.

Ghazala Azmat et al. IZA: What You Don't Know... Can't Hurt You? A Field Experiment on Relative Performance Feedback in Higher Education. This paper studies the effect of providing feedback to college students on their position in the grade distribution by using a randomized control experiment. This information was updated every six months during a three-year period. In the absence of treatment, students' underestimate their position in the grade distribution. The treatment significantly improves the students' self-assessment. We find that treated students experience a significant decrease in their educational performance, as measured by their accumulated GPA and number of exams passed, and a significant improvement in their self-reported satisfaction, as measured by survey responses obtained after information is provided but before students take their exams. Those effects, however, are short lived, as students catch up in subsequent periods. Moreover, the negative effect on performance is driven by those students who underestimate their position in the absence of feedback. Those students who overestimate initially their position, if anything, respond positively.
Indivar Dutta-Gupta et al., Georgetown Center on Poverty and Inequality: Lessons Learned From 40 Years of Subsidized Employment Programs. Subsidized employment programs have a wide range of potential benefits. First, these programs provide an important source of income to participating workers. Second, a number of experimentally-evaluated subsidized employment programs have successfully raised earnings and employment, with some programs providing lasting labor market impacts.4 Such programs have also decreased family public benefit receipt, raised school outcomes among the children of workers, boosted workers’ school completion, lowered criminal justice system involvement among both workers and their children, improved psychological well-being, and reduced longer-term poverty. There may be additional positive effects, such as increased child support.
Jutta Viinikainen et al., IZA: Born Entrepreneur? Adolescents' Personality Characteristics and Self-Employment in Adulthood. Is there an entrepreneurial personality and does it appear early in life? We provide a new answer on this question by using the so-called Type A behavior traits (Aggression, Leadership, Responsibility, and Eagerness-Energy), measured in childhood and adolescence, and examining their relationship to self-employment propensity in adulthood. Using data from the Young Finns Study linked to the Finnish Longitudinal Employer-Employee Data and the Longitudinal Population Census of Statistics, our results show that the early-life Leadership-dimension is significantly associated with a higher likelihood 1) of becoming self-employed later in life and 2) of being more successful as an entrepreneur, as approximated by sales. Our results also reinforce the prior evidence on the intergenerational transmission of entrepreneurship.
David Andolfatto: How old were the inventors of major inventions? I came across this fun column the other day listing a number of Famous Inventions, like the airplane, the camera, electricity, the car, etc, along with their inventors. A thought crossed my mind: how old were these inventors when they invented these inventions? Were they young like Marconi, who invented the radio in his early 20s? Or were they old like Gutenberg, who invented the printing press in his early 50s? In short, is there an age demographic that is responsible for producing major innovations? I have to admit, I was a little surprised--the median age is 40 (I was expecting younger).
Dan Nixon, BoE: Less is more: what does mindfulness mean for economics? Economic theory generally assumes that more consumption means greater happiness. This post puts forward an alternative, “less is more” perspective based around the concept of mindfulness. It argues that we may achieve greater happiness by seeking to simplify our desires, rather than satisfy them. The result – less consumption but greater wellbeing – could be especially important for debates around secular stagnation and ecological sustainability.
Holger Kirchmann, Lars Bergström,Thomas Kätterer, Rune Andersson, Fri tanke (2014): Den ekologiska drömmen. Myter och sanningar om ekologisk odling. Föreställningar om att ekologisk odling är klimatsmart och ger bättre livsmedel är felaktiga. Hundra procent ekologisk odling skulle vara en katastrof för framtida livsmedelsförsörjning och innebär större belastning på miljön till en hög kostnad. Konsumenterna får varken bättre livsmedel eller en bättre miljö om de köper ekologiskt odlad mat. Ekologiska livsmedel är inte giftfria. Ekomaten är inte heller nyttigare än konventionellt odlad mat. Ökad ekologisk odling försämrar allvarligt livsmedelsförsörjningen, både i Sverige och globalt. Ekoodling ger inte ett lägre utsläpp av näringsämnen till yt- och grundvatten. Ekoodling är inte klimatsmart.

Fernando Eguren-Martin, BoE: Friedman was right: flexible exchange rates do help external rebalancing. Do exchange rate regimes matter for the formation of countries’ external imbalances? Economists have thought so for over sixty years, and policymakers have made countless recommendations based on that presumption. But this had not been tested empirically until very recently, so it remained an opinion rather than a fact.  In this post I show that having a flexible exchange rate regime leads to the correction of external imbalances in developing countries, offering some empirical support to a widely held belief. In contrast, this does not seem to be the case for advanced economies.

Yi Che et al., NBER: Does Trade Liberalization with China Influence U.S. Elections? This paper examines the impact of trade liberalization on U.S. Congressional elections. We find that U.S. counties subject to greater competition from China via a change in U.S. trade policy exhibit relative increases in turnout, the share of votes cast for Democrats and the probability that the county is represented by a Democrat. We find that these changes are consistent with Democrats in office during the period examined being more likely than Republicans to support legislation limiting import competition or favoring economic assistance.
Courtney Coile, Kevin S. Milligan, David A. Wise, NBER: Social Security and Retirement Programs Around the World: The Capacity to Work at Older Ages - Introduction and Summary. We explore whether older people are healthy enough to work longer. We use two main methods to estimate the health capacity to work, asking how much older individuals today could work if they worked as much as those with the same mortality rate in the past or as younger individuals in similar health. Both methods suggest there is significant additional health capacity to work at older ages
Maria De Paola, Giorgio Brunello, IZA: Education as a Tool for the Economic Integration of Migrants. We examine the role of education in fostering the economic integration of immigrants. Although immigrants in Europe are – on average – slightly less educated than native individuals, there is a large heterogeneity across countries. We discuss evidence on student performance in international tests showing that children with an immigrant background display worse results than natives. While in some countries, such as Denmark and France, this gap is almost entirely explained by differences in socio-economic background, in others (Finland, Austria, Belgium and Portugal) the factors driving the gap are more complex and have roots also outside socio-economic conditions. We investigate how educational policies in the host count can affect the educational outcomes of immigrants. We focus our attention on pre-school attendance, school tracking, the combination of students and teacher characteristics, and class composition.
Maria Caridad Araujo et al., IZA: Teacher Quality and Learning Outcomes in Kindergarten. We assigned two cohorts of kindergarten students, totaling more than 24,000 children, to teachers within schools with a rule that is as-good-as-random. We collected data on children at the beginning of the school year, and applied 12 tests of math, language and executive function (EF) at the end of the year. All teachers were filmed teaching for a full day, and the videos were coded using a well-known classroom observation tool, the Classroom Assessment Scoring System (or CLASS). We find substantial classroom effects: A one-standard deviation increase in classroom quality results in 0.11, 0.11, and 0.07 standard deviation higher test scores in language, math, and EF, respectively. Teacher behaviors, as measured by the CLASS, are associated with higher test scores. Parents recognize better teachers, but do not change their behaviors appreciably to take account of differences in teacher quality.
GAO: Shorter Life Expectancy Reduces Projected Lifetime Benefits for Lower Earners. According to studies GAO reviewed, lower-income men approaching retirement live, on average, 3.6 to 12.7 fewer years than higher-income men. GAO developed hypothetical scenarios to calculate the projected amount of lifetime Social Security retirement benefits received, on average, for men with different income levels born in the same year. In these scenarios, GAO compared projected benefits based on each income groups' shorter or longer life expectancy with projected benefits based on average life expectancy, and found that lower-income groups' shorter-than-average life expectancy reduced their projected lifetime benefits by as much as 11 to 14 percent. Effects on Social Security retirement benefits are particularly important to lower-income groups because Social Security is their primary source of retirement income.
Allison Master et al., Washington Post: Researchers explain how stereotypes keep girls out of computer science classes. Despite valiant efforts to recruit more women, the gender gap in the fields collectively known as STEM — science, technology, engineering, and math — is not getting any better. The gaps in computer science and engineering are the largest of any major STEM discipline. Nationally, less than 20% of bachelor’s degrees in these fields go to women. Women are missing out on great jobs, and society is missing out on the innovations women could be making in new technology. Stereotypes are a powerful force driving girls away from these fields. Even though stereotypes are often inaccurate, children absorb them at an early age and are affected by them.
Tomek de Ponti, Bert Rijk, Martin K. van Ittersum, Agricultural Systems: The crop yield gap between organic and conventional agriculture. We compiled and analyzed a meta-dataset of 362 published organic–conventional comparative crop yields. Our review and meta-analysis of yield data comparing organic and conventional agriculture showed that currently organic yields of individual crops are on average 80% of conventional yields. In our dataset, the organic yield gap significantly differed between crop groups and regions.
Kacey Deamer, Livescience: Time to Change Your Sheets? Bedbugs Have Favorite Colors. Do bedbugs prefer their hiding places to be a certain color? Researchers conducted a series of tests in a lab to see if bedbugs (Cimex lectularius) would favor different-colored harborages, or places where pests seek shelter. The scientists found that bedbugs strongly prefer red and black, and typically avoid colors like green and yellow.

Stanley Fischer, FED: Reflections on Macroeconomics Then and Now. There is an old joke about our field--not the one about the one-handed economist, nor the one about "assume you have a can opener," nor the one that ends, "If I were you, I wouldn't start from here." Rather it's the one about the Ph.D. economist who returns to his university for his class's 50th reunion. He asks if he can see the most recent Ph.D. generals exam. After a while it is brought to him. He reads it carefully, looking perplexed, and then says, "But this is exactly the same as the exam I wrote over 50 years ago." "Ah yes," says the professor. "It is the same, but all the answers are different."

Gabriel Chodorow-Reich, Loukas Karabarbounis, NBER: The Limited Macroeconomic Effects of Unemployment Benefit Extensions. By how much does an extension of unemployment benefits affect macroeconomic outcomes such as unemployment? Answering this question is challenging because U.S. law extends benefits for states experiencing high unemployment.  We use data revisions to decompose the variation in the duration of benefits into the part coming from actual differences in economic conditions and the part coming from measurement error in the real-time data used to determine benefit extensions.  Using only the variation coming from measurement error, we find that benefit extensions have a limited influence on state-level macroeconomic outcomes.  We use our estimates to quantify the effects of the increase in the duration of benefits during the Great Recession and find that they increased the unemployment rate by at most 0.3 percentage point.
Steven D. Levitt, John A. List, Sally Sadoff, NBER: The Effect of Performance-Based Incentives on Educational Achievement: Evidence from a Randomized Experiment. We test the effect of performance-based incentives on educational achievement in a low-performing school district using a randomized field experiment.  High school freshmen were provided monthly financial incentives for meeting an achievement standard based on multiple measures of performance including attendance, behavior, grades and standardized test scores.  Within the design, we compare the effectiveness of varying the recipient of the reward (students or parents) and the incentive structure (fixed rate or lottery).  While the overall effects of the incentives are modest, the program has a large and significant impact among students on the threshold of meeting the achievement standard.  These students continue to outperform their control group peers a year after the financial incentives end.  However, the program effects fade in longer term follow up, highlighting the importance of longer term tracking of incentive programs.
Richard Blundell, Michael Grabera, Magne Mogstad, JPE: Labor income dynamics and the insurance from taxes, transfers, and the family. What do labor income dynamics look like over the life-cycle? We use rich Norwegian population panel data to answer these important questions. We find that the income processes differ systematically by age, skill level and their interaction. To accurately describe labor income dynamics over the life-cycle, it is necessary to allow for heterogeneity by education levels and account for non-stationarity in age and time. Our findings suggest that the redistributive nature of the Norwegian tax–transfer system plays a key role in attenuating the magnitude and persistence of income shocks, especially among the low skilled. By comparison, spouse's income matters less for the dynamics of inequality over the life-cycle.
Julia Tanndal, Daniel Waldenström, VOX: Big Bang financial deregulation and income inequality: Evidence from UK and Japan. Financial deregulation in the US has been shown to be associated with rising income inequality over the past four decades. This column looks at the income effects of financial deregulation in the UK and Japan during the 1980s and 1990s. As in the US, deregulation substantially increased the shares of income going to the very top of the distribution. These findings highlight the importance of financial markets in the evolution of income inequality in society.
Jeffrey Sparshott, WSJ:  Do Cheaters Ever Prosper? A Lesson From N.Y. Student Tests. A 2011 analysis for The Wall Street Journal showed a bulge in New York City students’ test scores right over the passing mark. The evidence strongly suggested teachers were manipulating grades on statewide Regents Exams and helped spur changes to testing procedures. Thomas Dee, a professor at Stanford University, updated the numbers from his initial analysis after the state took steps to eliminate grade inflation. The findings: Teachers who manipulated scores appear to have been motivated by altruism, score manipulation was eliminated by 2012, and the graduation gap between black and white students is about 5% larger in its absence.
David Downs, Scientific American: The Science behind the DEA's Long War on Marijuana. Experts say listing cannabis among the world’s deadliest drugs ignores decades of scientific and medical data. But attempts to delist it have met with decades of bureaucratic inertia and political distortion. Speculation is growing about the possibility that the U.S. Drug Enforcement Administration (DEA) will review by summer its “Schedule I” designation of marijuana as equal to heroin among the world’s most dangerous drugs.
Crystal Smith-Spangler et al., Annals of Internal Medicine: Are Organic Foods Safer or Healthier Than Conventional Alternatives? A Systematic Review. 17 studies in humans and 223 studies of nutrient and contaminant levels in foods met inclusion criteria 1966-2011. Only 3 of the human studies examined clinical outcomes, finding no significant differences between populations by food type for allergic outcomes (eczema, wheeze, atopic sensitization) or symptomatic Campylobacter infection. The published literature lacks strong evidence that organic foods are significantly more nutritious than conventional foods. Consumption of organic foods may reduce exposure to pesticide residues and antibiotic-resistant bacteria.

Lawrence Summers, Washington Post: What’s behind the revolt against global integration? The core of the revolt against global integration, though, is not ignorance. It is a sense — unfortunately not wholly unwarranted — that it is a project being carried out by elites for elites, with little consideration for the interests of ordinary people. They see the globalization agenda as being set by large companies that successfully play one country against another. They read the revelations in the Panama Papers and conclude that globalization offers a fortunate few opportunities to avoid taxes and regulations that are not available to everyone else. And they see the kind of disintegration that accompanies global integration as local communities suffer when major employers lose out to foreign competitors.

Peter Dizikes, MIT News: How network effects hurt economies. “Relatively small shocks can become magnified and then become shocks you have to contend with [on a large scale],” says MIT economist Daron Acemoglu. Study reveals how woes in one industry can harm others, too. The findings run counter to “real business cycle theory,” which became popular in the 1970s and holds that smaller, industry-specific effects tend to get swamped by larger, economy-wide trends. More precisely, Acemoglu and his colleagues have found cases where industry-specific problems lead to six-fold declines in production across the U.S. economy as a whole. For example, for every dollar of value-added growth lost in the manufacturing industries because of competition from China, six dollars of value-added growth were lost in the U.S. economy as a whole.
Roland G. Fryer, Jr, NBER: The Production of Human Capital in Developed Countries: Evidence from 196 Randomized Field Experiments. Randomized field experiments designed to better understand the production of human capital have increased exponentially over the past several decades.  This chapter summarizes what we have learned about various partial derivatives of the human capital production function, what important partial derivatives are left to be estimated, and what - together - our collective efforts have taught us about how to produce human capital in developed countries.  The chapter concludes with a back of the envelope simulation of how much of the racial wage gap in America might be accounted for if human capital policy focused on best practices gleaned from randomized field experiments.
Simen Markussen, Knut Roed, IZA: The Market for Paid Sick Leave. In many countries, general practitioners (GPs) are assigned the task of controlling the validity of their own patients' insurance claims. At the same time, they operate in a market where patients are customers free to choose their GP. Are these roles compatible? Can we trust that the gatekeeping decisions are untainted by private economic interests? Based on administrative registers from Norway with records on sick pay certification and GP-patient relationships, we present evidence to the contrary: GPs are more lenient gatekeepers the more competitive is the physician market, and a reputation for lenient gatekeeping increases the demand for their services.
Raj Chetty, JAMA: The Association Between Income and Life Expectancy in the United States. In the United States between 2001 and 2014, higher income was associated with greater longevity, and differences in life expectancy across income groups increased over time. However, the association between life expectancy and income varied substantially across areas; differences in longevity across income groups decreased in some areas and increased in others. The differences in life expectancy were correlated with health behaviors and local area characteristics.
Noah Smith, Bloombergs: Decline of the U.S. Middle Class. The percentages of Americans who consider themselves working class has stayed relatively stable. But the self-identified middle class has plunged by about 10 percentage points, matched by an even larger increase in the percentage of Americans who label themselves lower class. The self-identified lower class should probably be included in the working class that gets discussed in articles about Trump and Sanders.
Osea Giuntella, Fabrizio Mazzonna, IZA: If You Don't Snooze You Lose: Evidence on Health and Weight. Most economic models consider sleeping as a pre-determined and homogeneous constraint on individuals' time allocation neglecting its potential effects on health and human capital. Several medical studies provide evidence of important associations between sleep deprivation and health outcomes suggesting a large impact on health care systems and individual productivity. Yet, there is little causal analysis of the effects of sleep duration. This paper uses a spatial regression discontinuity design to identify the effects of sleep on health status, weight, and cognitive abilities. Our results suggest that delaying morning work schedules and school start times may have non-negligible effects on Health.
Axel Mie, Maria Wivstad, SLU (2015): Organic Food – food quality and potential health effects. A review of current knowledge, and a discussion of uncertainties. In this report, we try to approach the question “Is organic food healthier than conventional food?” from a scientific perspective. We can conclude that science does not provide a clear answer to this question. A small number of animal studies and epidemiological studies on health effects from the consumption of organic vs. conventional feed/food have been performed. These studies indicate that the production system of the food has some influence on the immune system of the consuming animal or human. However, such effects are not easily interpreted as positive or negative for health.
