Weather Forecasts and Farming Practices in India

article

Climate change is making weather patterns around the world more volatile, increasing risks for farmers. Providing farmers with accurate weather forecasts is one possible strategy for mitigating these risks. In Long-Range Forecasts as Climate Adaptation: Experimental Evidence from Developing-Country Agriculture (NBER Working Paper 32173), Fiona Burlig, Amir Jina, Erin M. Kelley, Gregory Lane, and Harshil Sahai report on a randomized trial in Indian villages that provided some farmers with a forecast of when the annual monsoon would begin. Farmers respond to news about monsoon...

Early-Life Lead Exposure and Old-Age Longevity

article

In the early decades of the twentieth century, many American cities installed municipal water systems. A wide range of materials were used for pipes, but lead was a common choice due to its durability, ease of installation, and relatively low incidence of leaks. In Toxified to the Bone: Early-Life and Childhood Exposure to Lead and Men’s Old-Age Mortality (NBER Working Paper 31957), Jason Fletcher and Hamid Noghanibehambari show that the use of lead pipes in these systems had detrimental effects on long-term health among residents of affected cities. 

The study examines the impact of early-life exposure to these lead pipes on longevity at older ages…

Unemployment in Informal Labor Markets in Developing Countries Figure

Unemployment in Informal Labor Markets in Developing Countries

article

Developing countries typically exhibit low rates of rural wage employment. For example, in India, male workers whose primary source of earnings is wage labor report working on only 46 percent of days per year. Bangladesh has a similarly low 55 percent rate of employment among landless males, and the rates are even lower in sub-Saharan Africa.

What do these low employment rates mean? One possibility is that they reflect extremely high involuntary unemployment. Alternatively, the rates could be an outcome of reasonably well functioning labor markets in which workers are simply choosing self-employment, which tends to be high in poor countries. These two possibilities have drastically different implications for understanding how well labor markets work and what role, if…

Immigration Policy and Entrepreneurs’ Choice of Startup Location

article

Immigrants play a significant role in the entrepreneurial landscape. In the United States, immigrants are 80 percent more likely to start businesses than native-born Americans. More than half of America's billion-dollar startup companies trace their roots to immigrant founders. There is limited research, however, on the factors that influence immigrants' decisions about where to locate their startup businesses. 

In The Effect of Immigration Policy on Founding Location Choice: Evidence from Canada's Start-up Visa Program (NBER Working Paper 31634), Saerom Lee and Britta Glennon investigate the impact of Canada's Start-up Visa Program on US-based…

Social Security and Retirement around the World

Social Security and Retirement around the World

article

Over the past 25 years, labor force participation at older ages has increased dramatically. In the 12 countries that are part of the NBER’s International Social Security (ISS) project, participation among those aged 60 to 64 has risen by an average of over 20 percentage points for men and over 25 percentage points for women.

In The Effects of Reforms on Retirement Behavior: Introduction and Summary (NBER Working Paper 31979), authors Axel Börsch-Supan and Courtney Coile report on the most recent work of the ISS project. The current analysis builds on previous project phases which showed that changes in health and education could…

Using New York State data from 2011 through 2021, Coleman DrakeDylan NagyMatthew D. Eisenberg, and David Slusky find that medical cannabis availability reduced the number of past-month self-reported poor mental health days by 3.4 percentage points a drop of about one tenth – among adults 65 and above.

In business environments dominated by information flows and autonomous tasks, the productivity gains from high levels of trust among employees are stronger than elsewhere, while strict hiring and firing regulations are more damaging, according to research by Gilbert CetteJimmy LopezJacques Mairesse, and Giuseppe Nicoletti.

A randomized controlled trial of different approaches to teaching math, involving about 4,000 students in two large school districts, shows that strategic use of technology can increase the scalability of high dosage tutoring,  Monica P. BhattJonathan GuryanSalman A. KhanMichael LaForest-Tucker, and Bhavya Mishra find.

Using nearly 75 years of data on survey forecasts of real GDP growth expectations, William N. GoetzmannAkiko Watanabe, and Masahiro Watanabe find that procyclical stocks, whose returns comove with business cycles, earn higher average returns than their countercyclical peers.  

After the 2002 Argentinean devaluation, Andrés BlancoAndrés Drenik, and Emilio Zaratiegui find that households at the bottom of the income distribution recovered faster than those at the top, in part because of low mobility and lack of union coverage among higher-income workers.
