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 2015-2016 Germany experienced a wave of predominantly low-skilled refugee immigration. We evaluate its macroeconomic and distributional effects using a quantitative overlapping generations model calibrated using German micro data to replicate education and productivity differentials between...

This paper investigates how the size of co-ethnic networks at the time of arrival affect the economic success of immigrants in Germany. Applying panel analysis with a large set of fixed effects and controls, we isolate the association between initial network size and long-run immigrant outcomes....

This paper studies the effects of threat on convergence to local culture and economic assimilation of refugees, exploiting plausibly exogenous variation in their allocation across German regions between 2013 and 2016. We combine novel survey data on cultural preferences and economic outcomes of...

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...

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...

This paper analyzes the spatial distribution of refugees over 1987-2017 and establishes several stylized facts about refugees today compared with past decades. Refugees still predominantly reside in developing countries neighboring their country of origin. However, compared to past decades,...

The number of refugees worldwide is now 12 million, up from 3 million in the early 1970s. And the number seeking asylum in the developed world increased tenfold, from about 50,000 per annum to half a million over the same period. Governments and international agencies have grappled with the twin...
