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.
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?
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.
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.
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.
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.
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.
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.
Tax collectors in developing countries collect far less tax revenue as a share of gross domestic product than tax collectors in higher income countries. In many of these developing countries, tax officials have discretion in assessing, enforcing, and auditing taxes. In addition, they earn relatively low wages with fewer rewards for good performance, allowing for the possibility of collusion with taxpayers. In the case of property taxes, officials may accept payments in exchange for leaving properties off the tax rolls, granting inappropriate exemptions, or assessing properties at a lower rate, all of which lead to lower revenues for the state.
Developing economies are typically characterized by low tax revenue and widespread tax evasion. This research shows that in such environments, it can be better to tax firms based on turnover rather than profits: while turnover taxes are known to distort production decisions, they are more difficult to evade than profit taxes. Analyzing administrative tax records from Pakistan, the study shows that the use of production-inefficient turnover taxes sharply reduces tax evasion and increases tax revenue.
Migration from rural areas of India to the city is surprisingly low compared with other large developing countries, leaving higher paying job opportunities unexploited. This research shows that well-functioning rural insurance networks are in part responsible for this misallocation in the labor market, creating incentives that keep adult males in the village. Policies that provide private credit to wealthy households or government safety nets to poor households would encourage greater rural-urban migration but they could also have unintended distributional consequences.
