The continuing inflow of hundreds of thousands of refugees into many European countries has ignited much political controversy and raised questions that require a fuller understanding of the determinants and consequences of refugee supply shocks. This paper revisits four historical refugee...

The Department of Homeland Security estimates that 11.4 million undocumented persons reside in the United States. Congress and President Obama are considering a number of proposals to regularize the status of the undocumented population and provide a “path to citizenship.” Any future change...

This paper examines the effect of cash transfers and food stamp benefits on family labor supply and welfare participation among two-parent families. The Aid to Families with Dependent Children-Unemployed Parent Program has been providing cash benefits to two-parent households since 1961 and...

Twenty-two million families currently receive a total of $34 billion dollars in benefits from the Earned Income Tax Credit (EITC). In fact, the EITC is the largest cash transfer program for lower-income families at the federal level. An unusual feature of the credit is its explicit goal to use...

Knowledge producers conducting research on a particular set of questions may respond to supply and demand shocks by shifting resources to a different set of questions. Cognitive mobility measures the transition from one location to another in idea space. We examine the cognitive mobility flows...

Although economic theory predicts an inverse relation between relative wages and immigration-induced supply shifts, it has been difficult to document such effects. The weak evidence may be partly due to sampling error in a commonly used measure of the supply shift, the immigrant share of the...

Labor supply theory makes strong predictions about how the introduction of a social welfare program impacts work effort. Although there is a large literature on the work incentive effects of AFDC and the EITC, relatively little is known about the work incentive effects of the Food Stamp Program...

The aim of this paper is to examine the labour market impact of in-work benefit reform in the UK. Evidence is drawn from the impact of earlier reforms in the UK and similar reforms in the US. We focus on the impact on labour supply -- employment and hours of work. In the US a large proportion of...

In recent years, the study of labor supply has occupied the attention of a large number of economists. With the growth in interest in the topic and with the inevitable diversity of economic models and statistical methods proposed by new entrants in the field, the literature has developed its own...

Labor supply theory predicts systematic heterogeneity in the impact of recent welfare reforms on earnings, transfers, and income. Yet most welfare reform research focuses on mean impacts. We investigate the importance of heterogeneity using random-assignment data from Connecticut's Jobs First...
