It is often argued that informal labor markets in developing countries promote growth by reducing the impact of regulation. On the other hand informality may reduce the amount of social protection offered to workers. We extend the wage-posting framework of Burdett and Mortensen (1998) to allow...

We develop and estimate an equilibrium job search model of worker careers, allowing for human capital accumulation, employer heterogeneity and individual-level shocks. Career wage growth is decomposed into the contributions of human capital and job search, within and between jobs. Human capital...

We present a constructive identification proof of p-linear decompositions of q-way arrays. The analysis is based on the joint spectral decomposition of a set of matrices. It has applications in the analysis of a variety of latent-structure models, such as q-variate mixtures of p distributions....

In this paper, we quantify the contribution of labor market reforms to unemployment dynamics in nine OECD countries (Australia, France, Germany, Japan, Portugal, Spain, Sweden, the United Kingdom and the United States). We build and estimate a dynamic stochastic search-matching model with...

We develop an equilibrium model of on-the-job search with ex-ante heterogeneous workers and firms, aggregate uncertainty and vacancy creation. The model produces rich dynamics in which the distributions of unemployed workers, vacancies and worker-firm matches evolve stochastically over time. We...

We consider an equilibrium search model with on-the-job search where Þrms set wages. If employers are perfectly aware of all workers job opportunities, then when an employee receives an outside job offer, it is optimal for their employer to try to retain them by matching the offer, so long as...

[eng] Two traditional assumption of dynamic demand models intertemporal separability and the recursivity of the utility function are here analyzed in detail .The kind of preferences underlying each utility function is first derived. We show that if separability easily accepts recursivity it is...
