Agricultural productivity and chronic disease

A half a century ago, new high-yield varieties of crops were introduced to India, and it transformed the country's farming. This so-called “Green Revolution” significantly boosted agricultural output, allaying concerns about famine and food security. But it may have had some unanticipated consequences for long-term health outcomes. In a paper in the American Economic Journal: Applied Economics, authors Sheetal Sekhri and Gauri Kartini Shastry show that the areas where agricultural productivity accelerated the most also saw the highest rates of diabetes among men later in life. The authors argue that substantial changes to the diets of mothers and young children, in the form of higher levels of rice consumption, likely increased the risks of chronic diseases. The findings suggest that dietary diversification should accompany efforts to promote agricultural production. Sekhri recently spoke with Tyler Smith about how the Green Revolution changed diets in India and why it led to a rise in diet-related diseases like diabetes.

Social organization and redistribution

Qualitative accounts of anthropologists indicate that social structure plays an important role in how resources are shared in society. But quantitative evidence measuring the impacts of social organization on financial ties and transfers has been lacking. In a paper in the American Economic Review, authors Jacob Moscona and Awa Ambra Seck helped to fill that gap. They found that in East Africa, cash transfer policies had very different effects in cultures organized by kinship ties compared to cultures organized around age groups. The findings suggest that social organization has a deep impact on how resources spread through economies and ultimately shape inequality. Jacob Moscona recently spoke with Tyler Smith about the difference between kin-based societies and age-based societies and how they affect development policies.

Broader economic impacts of the Paycheck Protection Program

The Paycheck Protection Program (PPP) was launched at the height of the COVID-19 pandemic in the hopes that it would keep businesses from laying off workers during government shutdown measures taken to contain the spread of the disease. Initial estimates of the direct impacts have been mixed, with some studies suggesting that the cost was hundreds of thousands of dollars per job saved. But a paper in the American Economic Journal: Economic Policy looked beyond the labor market at a second order effect showing a clear and positive benefit. Authors Sumit Agarwal, Brent W. Ambrose, Luis A. Lopez, Xue Xiao found that the PPP reduced mortgage delinquencies for commercial real estate by roughly $36 billion in 2020 and likely played an important role in averting wider distress in financial markets. Ambrose recently spoke with Tyler Smith about the impact of PPP loans on the commercial real estate market and ways in which the program could have been better targeted.

The political power of historical narratives

In 2005, Austria’s most prominent far-right party proclaimed a “Third Turkish Siege of Vienna.” The campaign warned voters that, like their ancestors who were almost overrun by the Ottoman Empire four centuries ago, they were being culturally invaded by Muslims. The campaigners hoped to use long-past historical events to shape the behavior and sentiments of modern-day voters. But did it work? The strategy sparked a surge in the far-right’s vote share and a wave of anti-Muslim sentiment, according to a paper in the American Economic Journal: Applied Economics. The authors, Christian Ochsner and Felix Roesel, studied areas with ties to the historical trauma of the Sieges of Vienna and explained how political innovators reinvigorated latent xenophobic narratives that mobilized voters. Ochsner recently spoke with Tyler Smith about the recent political environment in Austria, the use of historical parallels, and the impact on Muslim minorities.

The political consequences of NAFTA

In 1993, the North American Free Trade Agreement (NAFTA) was passed with bipartisan support and near universal endorsement by economists. In hindsight, the economic costs and political consequences were far greater than many contemporary observers would have imagined. In a paper in the American Economic Review, authors Jiwon Choi, Ilyana Kuziemko, Ebonya Washington, and Gavin Wright found that US counties most exposed to NAFTA and Mexican import competition saw their total employment drop by roughly 6 percent compared to those with little exposure to the trade deal. However, workers in these communities didn’t respond by moving away to find better opportunities, and many, feeling betrayed by the Democratic party, embraced the Republican party instead. Choi and Wright recently spoke with Tyler Smith about the economic and political history of NAFTA and what economists have learned since its passage.

Moral hazard and migration

Since 2014, over 15,000 migrants have died or gone missing trying to make the voyage from the north coast of Africa to southern Europe. In response, European authorities have launched several search and rescue operations. There are few signs that migration along this deadly route is slowing down. In fact, efforts to curb migrant deaths may encourage even more migrants to make the perilous journey. In a paper in the American Economic Journal: Economic Policy, authors Claudio Deiana, Vikram Maheshri, and Giovanni Mastrobuoni found evidence that migrants and smugglers responded to search and rescue operations by attempting even more dangerous crossings. However, the authors still say that such operations are likely beneficial to migrants on the whole. Maheshri recently spoke with Tyler Smith about the impact of search and rescue operations on the market for smuggling along the Central Mediterranean Route and what policymakers should do to reduce migrant deaths.

The pace of economics publishing

Timely publication of research in peer-reviewed journals is critical for economists seeking tenure and important for audiences looking for high-quality, trustworthy studies. But in recent decades, there has been an increasing concern that the pace of publishing in economics is too slow. In a paper in the Journal of Economic Literature, authors Aboozar Hadavand, Daniel S. Hamermesh, and Wesley W. Wilson analyzed the publication lag in top economics journals and compared it to other fields. They found that economics publishing takes nearly twice as long as comparable fields in the other social sciences. However, Hamermesh says that some innovative journals, such as AER: Insights, are taking steps to shorten the time between submission and publication. He recently spoke with Tyler Smith about the pace of publishing in economics, how to fix it, and some advice for young economists trying to publish their work.

Improving vaccine messaging

The COVID-19 pandemic highlighted the importance of vaccines, but it also underscored the reservations and low take-up rates among US citizens. In a paper in the American Economic Journal: Economic Policy, authors Marcella Alsan and Sarah Eichmeyer tested several approaches to improving messages aimed at boosting vaccine demand. Their main finding was that messages delivered by laypersons were more effective than those delivered by persons perceived to be doctors. Eichmeyer says that video messages delivered by experts who were of the same race or were perceived as empathetic can be effective for some types of viewers, but for the most hesitant, ordinary citizens may be the best positioned to dispel myths about vaccines. She recently spoke with Tyler Smith about the design of her and Alsan’s experiment and what their results imply about vaccine messaging.

Introducing the AEA Research Highlights podcast

Five years ago, the American Economic Association began posting short, readable summaries of the research published in our journals. We called them Research Highlights, and in that time, we’ve really seen the audience for these grow to include thousands of tenured professors, students, and everyday people who just want to learn more about economics. Now, we’re hoping to keep growing our audience by giving you something to listen to, as well.
