This paper characterizes the optimal redistributive taxation when individuals are heterogeneous in two exogenous dimensions: their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are...

A search model of the labor market is augmented to include commuting time to work. The theory posits that wages are positively related to commute distance, by a factor itself depending negatively on the bargaining power of workers. Since not all combinations of distance and wages are accepted,...

Wage determination under asymmetric information generates inefficiencies due to excess turnover. Severance pay and layoff taxes can improve efficiency. We show that inefficient separations can even be fully removed with fixed separation taxes in the case where the relevant private information is...

This paper builds a macroeconomic model of equilibrium unemployment in which firms persistently face difficulties in selling their production and this affects their decisions to create jobs. Due to search-frictions on the product market, equilibrium unemployment is a U-shaped function of the...

We propose a canonical model of optimal nonlinear redistributive taxation with matching unemployment. In our model, agents are endowed with different skill levels and labor markets are perfectly segmented by skill. The government only observes negotiated wages. More progressive taxation leads to...

This paper characterizes optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous across two dimensions: specifically, their skill and disutility of participation. Preferences over consumption and work effort can differ with...

We develop and estimate a non-stationary job search model to evaluate a scheme that monitors job search effort and sanctions insured unemployed whose effort is deemed insufficient. The model reveals that such schemes provide incentives to the unemployed to front-load search effort prior to...

Building a model with three imperfect markets - goods, labor and credit - representing a product's life-cycle, we find that goods market frictions drastically change the qualitative and quantitative dynamics of labor market variables. The calibrated model leads to a significant reduction in the...

Unemployment may depend on equilibrium in other markets than the labor markets. This paper adresses this old idea by introducing search frictions on several markets: in a model of credit and labor market imperfections as in Wasmer and Weil (2004), I further introduce search on the goods market....

In this paper we argue that, for a given overall level of labour income taxation, a more progressive tax schedule increases employment. From a theoretical point of view, higher progressivity increases overall employment through a wage moderating effect and also because employment of low-paid...
