Historical accounts suggest that Jewish émigrés from Nazi Germany revolutionized U.S. science. To analyze the émigrés' effects on chemical innovation in the U.S. we compare changes in patenting by U.S. inventors in research fields of émigrés with fields of other German chemists. Patenting...

The United States has admitted more than 3 million refugees since 1980 through official refugee resettlement programs. Scholars attribute the success of refugee groups to governmental programs on assimilation and integration. Before 1948, however, refugees arrived without formal selection...

We exploit differences in the mortality rates faced by European colonialists to estimate the effect of institutions on economic performance. Our argument is that Europeans adopted very different colonization policies in different colonies, with different associated institutions. The choice of...

In the late 19th and early 20th centuries, the North American agricultural frontier moved for the first time into semi-arid regions where farming was vulnerable to drought. Farmers who migrated to the region had to adapt their crops, techniques, and farm sizes to better fit the environment. But...

We present a conceptual framework to better understand the interaction between settlement and the emergence of de facto property rights on frontiers prior to governments establishing and enforcing de jure property rights. In this framework, potential rents associated with more exclusivity drives...

We evaluate the effect on newly arrived refugees' employment of a policy, introduced in Denmark in 2013, that matched refugees to occupations with local labor shortages after basic training for those jobs. Leveraging the staggered roll-out across municipalities, we find that the policy increased...

Virtually all theories of economic growth predict a positive relationship between population size and productivity. In this paper I study a particular historical episode to provide direct evidence for the empirical relevance of such scale effects. In the aftermath of the Second World War about...

In settings where an individual's labor choices are constrained, the inability to work may generate psychosocial harm. This paper presents a causal estimate of the psychosocial value of employment in the Rohingya refugee camps of Bangladesh. We engage 745 individuals in a field experiment with...

We analyze the impact on crime of 3.7 million refugees who entered and stayed in Turkey as a result of the civil war in Syria. Using a novel administrative data source on the flow of offense records to prosecutors' offices in 81 provinces of the country each year, and utilizing the staggered...

Social and economic integration of refugees are key to their personal fulfillment and to producing positive effects in the host country. We evaluate the impact of a reform that expanded and improved early language classes to refugees in Denmark while also temporarily lowering welfare benefits...
