With the goal of driving down drug costs, governments across the globe have instituted various forms of pharmaceutical price control policies. Understanding the impacts of such policies is particularly important in low- and middle-income countries, where lack of insurance coverage means that prices can serve as a barrier to access for patients and lack of effective quality control may allow for low-quality medicines in the market. In her paper, Emma Boswell Dean examines the theoretical effects of price controls in such markets and then measures the empirical effects of one implementation of pharmaceutical price controls, in which the Indian government placed price ceilings on a set of essential medicines.

There are over 25 million refugees in the world today and most of them—especially those in developing countries—do not have formal labor market access (LMA). Granting refugees formal LMA has the potential to create substantial benefits for refugees and their hosts.

When opportunities for corrupt earnings rise, is there more corruption? This fundamental question is the subject of new, frontier-pushing research by two young stars of development economics: CGD alumnus Sandip Sukhtankar and his co-author Paul Niehaus.

Do immigrants from poor countries hurt native workers? A study by an influential immigration economist at Harvard University recently found that a famous flood of Cuban immigrants into Miami dramatically reduced the wages of native workers. But there’s a problem. The Borjas study had a critical flaw that makes the finding spurious.

Using data collected by the North Carolina Growers’ Association (NCGA), the leading employer of workers with H-2 visas, Michael Clemens shows that foreign workers have almost no direct effect on the employment prospects of US workers in H-2 occupations. Instead, they actually a large and positive indirect effect on US employment by contributing to North Carolina’s economy.

Journalists have warned you that there are now 60 million refugees worldwide, and that Europe faces “the worst refugee crisis since World War II.” They’ve told you this again and again and again.
Fact check: It’s not true. Not even close.

The welcome rise of replication tests in economics has not been accompanied by a single, clear definition of ‘replication’. A discrepant replication, in current usage of the term, can signal anything from an unremarkable disagreement over methods to scientific incompetence or misconduct. This paper proposes an unambiguous definition of replication, one that reflects currently common but unstandardized use. It contrasts this definition with decades of unsuccessful attempts to standardize terminology, and argues that many prominent results described as replication tests should not be described as such. Adopting this definition can improve incentives for researchers, encouraging more and better replication tests.

The arrival of more than a million refugees and migrants in Europe has brought widespread concern they will become an economic drain on the countries that welcome them. When economists have studied past influxes of refugees and migrants they have found the labor market effects, while varied, are very limited, and can in fact be positive.

Workers from poor countries can find enormous economic opportunity by working temporarily in a rich country. But agencies that fight global poverty do little to facilitate guest work. This may be because guest workers are perceived to typically suffer negative side effects that outweigh the benefits. This paper uses a natural experiment to test several perceptions of harmful side-effects on Indian guest workers in the Gulf. The research shows little evidence that the harmful side-effects often ascribed to guest work are typical and systematic, though this does not contradict the occurrence of many individual cases of harmful side-effects.

This paper studies the relationship between violence in the Northern Triangle and child migration to the United States. It finds that one additional homicide per year in the region, sustained over the six-year period of study—that is, a cumulative total of six additional homicides—caused a cumulative total of 3.7 additional unaccompanied child apprehensions in the United States. The explanatory power of short-term increases in violence is roughly equal to the explanatory power of long-term economic characteristics like average income and poverty.

An influential strand of research has tested for the effects of immigration on natives’ wages and employment using exogenous refugee supply shocks as natural experiments. Several studies have reached conflicting conclusions about the effects of noted refugee waves such as the Mariel Boatlift in Miami and post-Soviet refugees to Israel. As a whole, the evidence from refugee waves reinforces the existing consensus that the impact of immigration on average native-born workers is small, and fails to substantiate claims of large detrimental impacts on workers with less than high school.

We study a natural experiment that excluded almost half a million Mexican ‘bracero’ seasonal agricultural workers from the United States, with the stated goal of raising wages and employment for domestic farm workers. We reject the wage effect of bracero exclusion required by the model in the absence of induced technical change, and fail to reject the hypothesis that exclusion had no effect on US agricultural wages or employment. Important mechanisms for this result include both adoption of less labor-intensive technologies and shifts in crop mix.

Large international differences in the price of labor can be sustained by differences between workers, or by natural and policy barriers to worker mobility. We use migrant selection theory and evidence to place lower bounds on the ad valorem equivalent of labor mobility barriers to the United States. Natural and policy barriers may each create annual global losses of trillions of dollars.

For decades, migration economics has stressed the effects of migration restrictions on income distribution in the host country. Recently the literature has taken a new direction by estimating the costs of migration restrictions to global economic efficiency. In contrast, a new strand of research posits that migration restrictions could be not only desirably redistributive, but in fact globally efficient. This is the new economic case for migration restrictions: empirically, a case against the stringency of current restrictions.

Many developing countries need the World Bank’s capital less and less. What role should the Bank play in the 21st century? This paper argues that many features of the Bank today reflect a new role. That role, resting on the economic theory of bargaining and public good provision, is to reduce extreme poverty. Donor subsidies to the Bank already reflect this role, which implies new ways to structure and evaluate the Bank’s work.
