This paper provides a structural estimation of an equilibrium search model with on-thejob search and heterogeneity in firms productivities using a sample of Italian workers. Allowing for productivity differentials among firms, the model is able to fit the wage distribution satisfactorily....

In market economies, identical workers appear to receive very different wages, violating the "law of one price" of Walrasian markets. We argue in this paper that in the absence of a Walrasian autioneers to coordinate trade": (i) wage dispersion among identical workers is very often an...

In this paper we extend a job search-matching model with firm-specific investments in training developed by Mortensen (1998) to allow for different offer arrival rates in employment and unemployment. The model by Mortensen changes the original wage posting model (Burdett and Mortensen, 1998) in...

The wage posting approach to search equilibrium is incorporated into the equilibrium unemployment approach in the paper. The unique equilibrium to the wage posting game analysed is a distribution of wage offers of the same functional form as that originally derived by Burdett and Mortensen...

In market economies, identical workers receive very different wages, violating the Walrasian 'law of one price'. We argue that in the absence of a Walrasian auctioneer to coordinate trade, wage dispersion among identical workers is an equilibriu m phenomenon. Moreover, wage dispersion is...

We propose a search equilibrium model in which homogenous firms post wages along with a vacancy to attract job-seekers, while homogenous unemployed workers invest in costly search. The key innovation relies on the organization of the search market and the search behavior of the job-seekers. The...

In market economies identical workers appear to receive very different wages, violating the ‘law of one price’ of Walrasian markets. It is argued in this paper that in the absence of a Walrasian auctioneer to coordinate trade: (i) wage dispersion among identical workers is very often an...

Economists and sociologists disagree over markets' potential to assume functions typically performed by networks of personal connections, first among them the transmission of information. This paper begins from a model of labor markets where social ties are stronger between similar individuals...

Wage inequality in the United States has grown substantially in the past two decades. Standard supply-demand analysis in the empirics of inequality (e.g.Katz and Murphy (1992)) indicates that we may attribute some of this trend to an outward shift in the demand for high skilled labor. In this...
