We analyze the impacts of labor market integration and migration on skill formation, wage structures, and per capita GDP of host and source countries. To do so, we propose a model in which heterogeneous agents invest in the acquisition of skills, and in which final good production exhibits...

We examine how much of the observed wage dispersion among similar workers can be explained as a consequence of a lack of coordination among employers. To do this, we construct a directed search model with homogenous workers but where firms can create either good or bad jobs, aimed at either...

This paper studies skill-neutral technological changes in an economy where workers differ with respect to their abilities to acquire skills, implying increasing marginal costs of educating the work force. Our main result is that productivity slowdown and increasing wage dispersion can be...

I examine whether a version of the Cahuc et al. (2006) model can match the magnitude of wage dispersion, as measured by the ratio of the average and the lowest wage - the so-called mean-min ratio of Hornstein et al. (2011). I find that the workers' bargaining power is a crucial parameter: the...

Increases in wage inequality and atypical employment have occurred across post-industrial economies in recent decades. Technological change, globalization, the employment shift to services, and the decentralization of collective bargaining are commonly cited as causes. I argue that where social...

Over the past decade, the share of jobs not controlled by the state has increased considerably, whilst employment in agriculture has declined, against the backdrop of ongoing urbanisation. Over 200 million people have been drawn into urban areas through official or unofficial migration, despite...

This paper investigates the effects of a decrease in fixed costs on the division of labor within firms. In the constant markup rate model, a decrease in fixed costs curbs the division of labor. In the short run, the division of labor is promoted through labor reallocation within firms while in...

This paper asks the following important question: what was the effect of surging immigration on average and individual wages of U.S.-born workers during the period 1990-2004? Building on section VI I of Borjas (2003) we emphasize the need for a general equilibrium approach to analyze this...

We present a competing-auction theory of the labor market, where job candidates auction their labor services to employers. An equilibrium matching function emerges which has many of the features commonly assumed, including constant returns to scale in large economies. The auction mechanism also...
