The majority of the world’s population lives in low-income countries where market failures are pervasive and governments’ budgets are tight. Research in development economics addresses the following questions:

What keeps individuals in poverty?
What keeps firms small and unable to expand?
Which policies have been effective at enabling resources to flow more easily to their most productive use, thus raising incomes?
What approaches have been effective at improving government performance, e.g. through incentives for agents delivering public services and the design of the tax system?

Cash Transfers and Nonlinear Prices

Cash transfer programs have become increasingly popular in developing countries over the past twenty years. Recently, World Bank researchers have documented a dramatic expansion of such programs to address the Covid-19 crisis. The reason for the popularity of these programs is that they have proved successful at alleviating poverty in both the short run, by […]

Tackling Youth Unemployment: Evidence from a Labor Market Experiment in Uganda

Motivation: youth unemployment as a global challenge Young people face a higher risk of unemployment than adults in all countries of the world (ILO 2020). Understanding which active labor market policies are effective at facilitating the transition of youth into remunerative employment is thus critical to ensure global economic and social stability. Nowhere is the […]

Age of marriage, weather shocks, and the direction of marriage payments

Child marriage, defined as marriage before the age of 18, is a widespread phenomenon in many parts of the world. About half of all prime-aged women living today in South Asia and in Sub-Saharan Africa were married as children (UNICEF 2014). Child marriage has been associated with a wide array of poor economic, social, and […]

Understanding the Average Impact of Microcredit

The global microloan portfolio is now worth over 102 billion dollars and is growing yearly. This research estimates the impact of the policy and the extent to which this impact is different across different contexts. It finds that overall, the best existing evidence suggests that the average impact of these loans is small and that in the future, it may be beneficial to seek alternative approaches to improve the lives of poor households in the developing world.

Nominal wage rigidity in village labor markets: evidence from India

Markets for daily wage labor are ubiquitous in poor countries, providing employment for hundreds of millions of workers in India alone. In an exploration of how nominal wages in these markets respond to changing economic conditions, this research finds strong evidence of limited downward adjustment in the face of a negative shock. A key part of the explanation lies in perceptions that wage cuts are unfair and reduce worker productivity. The higher unemployment that results from nominal wage rigidity could be addressed by counter-cyclical employment programs, and by modest levels of inflation that allow real wages to adjust in a way that avoids too much harm to workers.

Tax evasion and inequality

How widespread is tax evasion – and what does that imply for the true extent of inequality? This research explores these questions by analyzing a unique dataset of leaked customer lists from offshore financial institutions matched to administrative wealth records in Scandinavia. The results show that offshore tax evasion is highly concentrated among the rich. The top 0.01% of households by wealth evade about a quarter of the taxes they owe, largely by concealing assets and investment income abroad. Top wealth shares in Denmark, Norway and Sweden increase substantially when adding back these unreported assets, highlighting the need to take account of tax evasion to measure inequality accurately.

Growth and well-being: policy should not be based on GDP alone

Economists are often accused of focusing excessively on GDP, with the result that government policies make GDP a priority to the detriment of other contributors to well-being. This research proposes a broader summary statistic that incorporates consumption, leisure, mortality and inequality. While the new statistic is highly correlated with GDP per capita, cross-national deviations are often large: Western Europe looks considerably closer to the United States; emerging Asia has not caught up as much; and many developing countries are further behind. Each component of the statistic plays a significant role in explaining these differences, with mortality being the most important. While still imperfect, the statistic arguably provides better guidance for determining public priorities and evaluating policies than does GDP alone.

Cultural proximity and loans

In many, many cases, people have a preference for working and doing business with those who share the same religious beliefs, come from the same geographic region, or have something else in common. If this preference arises from discrimination against other groups – if there is economically inefficient favoritism – the economy will not reach its full potential. But could there also be efficiency gains from transacting with people who are culturally proximate? If so, is it possible for the gains to be large enough to more than offset the losses from discrimination? Surprisingly, the answer to both questions is yes. However, that does not mean the barriers between groups should be reinforced. Policies that break down informational barriers between groups could produce further gains.

Absolute poverty: when necessity displaces desire

The number of people living in poverty in countries around the world is commonly measured using the World Bank’s poverty line – the ‘$1 per day’ that many people have heard of, though it has risen over time and now stands at $1.90 per day. However this measure assumes that the needs of the poor are the same in every country, an assumption at odds with the evidence and common sense. This paper develops a Basic Needs Poverty Line that overcomes this problem giving us new and in some cases surprising insight into the severity of the poverty problem in both rich and poor countries around the world.

Economic benefits of transportation infrastructure: historical evidence from India and America

Dave Donaldson is an empirical trade economist and recipient of the 2017 John Bates Clark Medal. His research examines the intersection of international trade and development economics. Donaldson’s paper “Railroads of the Raj: Estimating the Impact of Transportation Infrastructure?” (American Economic Review, forthcoming) investigates the economic benefits from building transportation infrastructure studying the case of railways in 19th century India. This paper is widely viewed as both a methodological breakthrough and substantively important paper in the field. The article below provides a summary of his work.
