A controversial issue in the US is how to reduce the number of illegal immigrants and what effect this would have on the US economy. To answer this question we set up a two-country model with search in labor markets and featuring legal and illegal immigrants among the low skilled. We calibrate...

Using nationally representative data on consumption, we show that Blacks and Hispanics devote larger shares of their expenditure bundles to visible goods (clothing, jewelry, and cars) than do comparable Whites. We demonstrate that these differences exist among virtually all sub-populations, that...

This paper constructs a tractable general equilibrium model of search with risk-aversion. An increase in risk-aversion reduces wages, unemployment, and investment. Unemployment insurance (UI) has the reverse effect due to market generated moral hazard: insured workers seek high wage jobs with...

A model is presented in which people base their labor search strategy on the average wage and the average unemployment duration of people who belong to their peer group. It is shown that, if the distribution of wage offers is not stationary so lower wage offers tend to arrive before higher wage...

This article examines and quantifies the relationship between local amenities and prices in an equilibrium model, demonstrating the role of non-traded goods and federal taxes. I derive formulae using factor shares to infer local land rents, productivity, and the total value of amenities from...

The standard revealed-preference estimate of a city's quality of life is proportional to that city's cost-of-living relative to its wage-level. Adjusting estimates to account for federal taxes, non-housing costs, and non-labor income produces more plausible quality-of-life estimates than in the...

We develop and apply a procedure to flexibly estimate intra-national border barriers and intra-regional trade costs. Bilateral border barriers very significantly depress Canadian inter-provincial trade for some pairs, though the overall effect is rather small. Bilateral distance imposes much...

Measures of entrepreneurship, such as average establishment size and the prevalence of start-ups, correlate strongly with employment growth across and within metropolitan areas, but the endogeneity of these measures bedevils interpretation. Chinitz (1961) hypothesized that coal mines near...

This paper explores the geographic overlap of trade and technology shocks across local labor markets in the United States. Regional exposure to technological change, as measured by specialization in routine task-intensive production and clerical occupations, is largely uncorrelated with regional...

This chapter reviews academic research on the connections between agglomeration and innovation. We first describe the conceptual distinctions between invention and innovation. We then describe how these factors are frequently measured in the data and some resulting empirical regularities....
