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...

This paper shows empirically that the non-employment effects of unemployment insurance (UI) for older workers depend in a first-order way on the structure of retirement policies. Using German data, we first present reduced-form evidence of these interactions, documenting large bunching in UI...

Employment rates in the United States fell dramatically between February 2020 and April 2020 as the repercussions of the COVID-19 pandemic reverberated through the labor market. This paper uses data from the CPS Basic Monthly Files to document that the employment decline was particularly severe...
