I propose a language theory of labor market segmentation. People of different language origins form separate urban labor submarkets and can switch between submarkets. Two types of wage differentials emerge, namely the Within-Labor-Market Wage Gap and the Within-Language-Group Wage Gap. The...

We provide the first analysis of the short-run causal impact of immigrant inflows on native populations at the local labor market level. Using published statistics from the American Community Surveys of 2000–2010, we examine how immigrant inflow shocks to a metropolitan area affect native...

We study the effect of immigration of foreign-trained, registered nurses (RNs) on the employment and wages of US-trained RNs. We use the “area” approach and study effects of immigration in labor markets defined by the state. We find substantial evidence that immigration by foreign-trained...

We study the effect of cultural ties on economic exchange using a novel measure for cultural identity: dialects. We evaluate linguistic micro-data from a unique language survey conducted between 1879 and 1888 in about 45,000 German schools. The recorded geography of dialects comprehensively...

Workers change occupation and industry less often in more densely populated areas, a relationship that had not been previously reported. This reduced-form result is robust to standard demographic controls, as well as to including aggregate measures of human capital and sectoral mix. Analysis of...

One goal of state merit-based financial aid programs is to increase the stock of college-educated labor in the state by retaining college-educated persons in the state after college. However, there has been surprisingly little research on whether state merit aid programs are effective at this...

The unemployment rate in France is roughly 6 percentage points higher for African immigrants than for natives. In the US the unemployment rate is approximately 9 percentage points higher for blacks than for whites. Commute time data indicates that minorities face longer commute times to work,...

Using a simple adverse selection model, we characterize equilibrium when the rich chase the poor. If communities are established by competitive entrepreneurs, the equilibrium exists, is unique, and is efficient. It involves either complete separation, or complete pooling. Different income groups...

This paper examines the effect of rental housing development subsidized by the federal government’s Low-Income Housing Tax Credit (LIHTC) program on local crime. Under the LIHTC program, certain high-poverty census tracts receive Qualified Census Tract (QCT) status, which affects the size of...

The impacts of energy price boom and bust are analyzed through the differential growth in employment and earnings between local labor markets with and without energy resources in Western Canada. The estimated differentials attributed to the boom-induced labor demand shocks show significant...
