Dans son ouvrage, Le capital au XXIe siècle, Thomas Piketty souligne les risques d’une explosion des inégalités de patrimoine, car le capital augmenterait plus vite que le revenu dans plusieurs pays, dont la France. Nous reviendrions ainsi au niveau des inégalités du début du XXe...

Il est vain de prétendre à l’exhaustivité en matière de lutte contre les discriminations. Les actions à mener sont multiples et doivent être combinées pour produire leurs effets. Ici, notre contribution consiste surtout dans le classement des actions à conduire en fonction du type de...

In an economy with search on credit and labor markets, a financial multiplier raises the elasticity of labor market tightness to productivity shocks. This multiplier increases with total financial costs, which are minimized under a credit market Hosios-Pissarides rule. Relaxing that condition...

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 attempt to understand the determinants of mobility by introducing the concept of local social capital. Investing in local ties is rational when workers anticipate that they will not move to another region. Reciprocally, once local social capital is accumulated, incentives to...

The Mortensen-Pissarides model with unemployment benefits and taxes has been able to account for the variation in unemployment rates across countries but does not explain why geographical mobility is very low in some countries (on average, three times lower in Europe than in the U.S.). We build...

European labor markets are characterized by the low geographical mobility of workers. The absence of mobility is a factor behind high unemployment when jobless people prefer to remain in their home region rather than to go prospecting in more dynamic areas. In this paper, we attempt to...

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,...

Building a model with three imperfect markets - goods, labor and credit - representing a product’s life-cyle, 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...

A model is developed that allows for interaction between the labor market and the housing market. A job location has an associated commuting time that may affect the job acceptance decision. Obstacles to mobility, such as regulations in the housing market will affect the reservation strategy of...
