We examine the labor market consequences of an extensive campaign repatriating around 400,000 Mexicans in 1929-34. To identify a causal effect, we instrument county level repatriations with the existence of a railway line to Mexico interacted with the size of the Mexican communities in 1910....

We apply the Synthetic Control Method to re-examine the effects of the Mariel Boatlift, a large inflow of Cubans into Miami in 1980, first studied by David Card (1990). This method improves on previous studies by choosing a control group so as to best match Miami's labor market features before...

We present a method to conduct automated surveys over WhatsApp, a globally popular messaging service. WhatsApp surveys offer potential advantages since they incur relatively low costs to respondents and researchers, are easy to use for respondents who are already familiar with WhatsApp chat...

We study the role of institutions in affecting the labor market impacts of immigration using a cross-country meta-analysis approach. To accomplish this, we gather information on 1,030 previously estimated wage effects and 432 employment effects of immigration from 61 academic studies covering 18...

Recent correlational studies and media reports have suggested that sleep regularity – the variation in the amount of sleep one gets across days – is a stronger determinant of student success than sleep duration – the total amount of sleep one receives. We identify the causal impacts of...

Many countries have reduced refugee admissions in recent years, in part due to fears that refugees and asylum seekers increase crime rates and pose a national security risk. Existing research presents ambiguous expectations about the consequences of refugee resettlement on crime. We leverage a...

In response to the COVID-19 pandemic, many states have adopted stay-at-home orders, rendering a large segment of the workforce unable to continue doing their jobs. These policies have distributional consequences, as workers in some occupations may be better able to continue their work from home....

We study the role of institutions in affecting the labor market impacts of immigration using a cross-country meta-analysis approach. To accomplish this, we gather information on 1,030 previously estimated wage effects and 432 employment effects of immigration from 61 academic studies covering 18...

Previous research has documented lower vaccination rates among ethnic and racial minorities as well as foreign-born people, thus raising concerns about health inequities during pandemics. We analyzed influenza vaccination rates among children with US-born parents and those with at least one...

Sleep studies suggest that girls go to sleep earlier, are more active in the morning, and cope with sleep deprivation better than boys. We provide the first causal evidence on how gender differences in sleep cycles can help explain the gender performance gap. We exploit over 240,000...
