Empirical studies in the migration literature have shown that migration enclaves (networks) negatively affect the language proficiency of migrants. These studies, however, ignore the choice of location as a function of language skills. Using data on Mexican migration to the US, we show that...

This paper presents a theory explaining the labor market matching process through microeconomic incentives. There are heterogeneous variations in the characteristics of workers and jobs, and firms face adjustment costs in responding to these variations. Matches and separations are described...

This paper investigates the extent to which expansion of international production by US multinationals reduces labour demand at home and at other foreign locations in the presence of labour adjustment costs. The adjustment-cost model of the firm is applied to estimate short-run and long-run...

We study the dynamics of optimal trade policy in a model with costly inter-sectoral adjustment of labour, where migrants pay less than the marginal social cost of migration. If workers have rational expectations, a future tariff has an announcement effect on the current migration decision. If...

This paper examines the effects of three alternative rules for public investment on output growth in a model with private and public capital. The rules considered are: (i) a fixed ratio of public capital to output; (ii) a fixed growth rate for public capital; and (iii) a fixed ratio of public...

This paper studies the costs of adjusting employment, distinguishing between firms' firing and workers' mobility costs. We construct a simple dynamic general equilibrium model of labour demand and supply and show that only the joint response of employment and wages to firm level shocks can...

Several theoretical models of money demand imply non-linear functional forms for the aggregate demand for money characterized by smooth adjustment towards long-run equilibrium. In this Paper, we propose a non-linear equilibrium correction model of US money demand, which is shown to be stable...

In this paper, we analyse employment and capital adjustments using a panel of plants from Colombia. We allow for nonlinear adjustment of employment to reflect not only adjustment costs of labour but also adjustment costs of capital, and vice-versa. Using data from the Annual Manufacturing...

This paper explores the two common concepts of the natural rate of unemployment: (i) the stable, long-run equilibrium rate of unemployment; and (ii) the equilibrium unemployment rate at which there is no tendency for this rate to change, given the exogenous variables. The first concept (common...

This paper examines transition dynamics in a search economy. We contrast two extreme cases: a completely unexpected reform and a fully anticipated reform. We view the former as a metaphor for a reform being announced and implemented with immediate effect, the latter as a metaphor for a reform...
