This paper presents a short overview of dynamic models of labor markets with transaction costs. It shows that these models have deeply renewed the understanding of job search, job flows, job creations and destructions, unemployment and wage formation. It argues that this renewal provides a very...

This paper analyses the relationship between social networks and the job search behaviour of individuals. Networking is not only based on friends and relatives but also on neighbourhood. The geographic closeness is associated to social interactions. Individuals who are in physical and social...

Two stylized representations are often found in the academic and policy literature on informality and formality in developing countries. The first is that the informal (or unregulated) sector is more competitive than the formal (or regulated) sector. The second is that contract enforcement is...

We study the impact of tax and minimum wage reforms on the incidence of informality. To gauge the incidence of informality, we use measures of the extent of tax evasion, the extent of minimum wage non-compliance, and the size of the informal workforce. Our approach allows us to examine (i) the...

It is often argued that a mandatory minimum wage is binding only if the wage density displays a spike at it. In this paper we analyze a model with search frictions and heterogeneous production technologies, in which imposition of a minimum wage affects wages even though, after imposition, the...

Labor Market Intermediaries (LMIs) are entities or institutions that interpose themselves between workers and firms to facilitate, inform, or regulate how workers are matched to firms, how work is accomplished, and how conflicts are resolved. This paper offers a conceptual foundation for...

In this paper we define and estimate measures of labor market frictions using data on job durations. We compare different estimation methods and different types of data. We propose and apply an unconditional inference method that can be applied to aggregate duration data. It does not require...

This paper applies recent advances in the study of labor market dynamics to a representative developing country with a large unregulated of "informal" sector. It confirms the relevance of the recent mainstream models and debates surrounding gross worker flows to the developing country context,...

This paper provides an overview of the main findings of the book "Social Insurance and Labor Markets: How to Protect Workers While Creating New Jobs." The book conceptualizes and reviews the empirical evidence on the potential distortions that the social insurance system of a country can have on...
