This paper analyses the effects of money shocks on macroeconomic aggregates in a flexible-price, incomplete-markets environment that generates persistent wealth inequalities amongst agents. In this framework, unexpected money shocks redistribute wealth from the cash-rich employed to the...

This paper analyzes the long-run effect of monetary policy when credit constraints are taken into account. This analysis is carried on in a heterogeneous agents framework in which infinitely lived agents can partially self-insure against income risks by using both financial assets and real...

In this paper we develop a new empirical approach to uncovering the impact of social attitudes on economic development. We first show that trust of second-generation Americans is significantly influenced by the country of origin of their forebears. In the spirit of the epidemiology literature,...

We argue that the efficiency of the Danish flexicurity Model, which combines high unemployment benefits with low job protection and high participation rate, relies on strong public-spiritedness. We also argue that Continental and Mediterranean European countries are unlikely to be able to...

Les essais contenus dans cette thèse utilisent des preuves empiriques pour répondre à deux questions qui sont d'une importance capitale compte tenu de notre compréhension croissante de la relation de préférences sociales et de la croissance économique et le bien-être au niveau des pays :...

We explore the consequences of public employment for labour market performance. Theory suggests that public employment may not only crowd out private employment, but also increase overall unemployment if, by offering attractive working conditions, it draws additional individuals into the labour...

In a cross-section of countries, government regulation is strongly negatively correlated with social capital. We document this correlation, and present a model explaining it. In the model, distrust creates public demand for regulation, while regulation in turn discourages social capital...

OECD countries faced largely divergent employment rates during the last decades. But the whole bulk of the cross-national and cross-temporal heterogeneity relies on specific demographic groups: prime-age women and younger and older individuals. This paper argues that family labour supply...

A new algorithm is developed to solve models with heterogeneous agents and aggregate uncertainty that avoids some disadvantages of the prevailing algorithm that strongly relies on simulation techniques and is easier to implement than existing algorithms. A key aspect of the algorithm is a new...

This paper shows that employment protection is influenced by the male breadwinner conception which is itself shaped by religions. First, by using international individual surveys, we document that Catholics, Muslims and Orthodoxs are more likely to support such "macho values" than Protestants...
