We construct a simple equilibrium search model in which workers accumulate information about previously met employment contacts. We term the latter search capital. Here search capital (partially) insures workers against adverse shocks. The model provides a theory of job-to-job transitions that...

An employer-employee panel is used to study whether the movement of workers across firms is a channel of unintended diffusion of R&D-generated knowledge. Somewhat surprisingly, hiring workers from others’ R&D labs to one’s own does not seem to be a significant spillover channel. Hiring...

This paper identifies a data-consistent, equilibrium model of unemployment, wage dispersion, quit turnover and firm growth dynamics. In a separating equilibrium, more productive firms signal their type by paying strictly higher wages in every state of the market. Workers optimally quit to firms...

The relationships among geographical mobility, unemployment and the value of owner-occupied housing are studied in an economy with heterogeneous locations and search frictions in the markets for both labour and houses. Differences in labour market conditions between cities affect the speed with...

Switching from one job to another would appear to be an important part of an individual's experience within the labour market. In Britain, approximately one in three workers are observed changing jobs over a three year period. Models of voluntary job mobility predict that in the long run,...

We develop a heterogeneous-firms model with trade in goods, labor mobility and credit constraints due to moral hazard. Mitigating financial frictions reduces the incentive of high-skilled workers to migrate to one region such that an unequal distribution of industrial activity becomes less...

This paper analyzes the effects of trade liberalisation on the political support for policies that redistribute income between workers in different sectors. We allow for worker heterogeneity and imperfect mobility of workers across sectors, giving rise to a trade-off between redistribution and...
