When one's treatment status affects the outcomes of others, experimental data are not sufficient to identify a treatment causal impact. In order to account for peer effects in program response, we use a social network model. We estimate and validate the model on experimental data collected for...

This paper uses data from the Luxembourg Income Study to examine some of the forces that have driven changes in household income inequality over the last three decades of the 20th century. We decompose inequality for 6 countries (Canada, Germany, Norway, Sweden, the UK, and the US) into the...

Leaders' misbehaviors may durably undermine the credibility of the state. Using individual level survey in the aftermath of geo-localized social protests in Africa, we find that trust in monitoring institutions and beliefs in social coordination strongly evolve after riots, together with trust...

We examine the determinants of income inequality and mobility in a Ramsey model with elastic labor supply. Individuals differ both in their initial capital endowment and productive ability (labor endowment). With two sources of heterogeneity, initially poorer agents may catch up with the income...

The widely used Oaxaca decomposition applies to linear models. Extending it to commonly used nonlinear models such as binary choice and duration models is not straightforward. This paper shows that the original decomposition using a linear model can be obtained as a first order Taylor expansion....

Les circuits courts alimentaires apparaissent aujourd'hui comme une réalité multiforme, en expansion et de plus en plus structurés, que les collectivités cherchent à accompagner dans leur développement. Avant d'envisager la structuration des filières, il s'agit d'identifier des Systèmes...

We show the existence of a twin peaks relation between trust and the size of the welfare state that stems from two opposing forces. Uncivic people support large welfare states because they expect to benefit from them without bearing their costs. But civic individuals support generous benefits...

Cette étude s'intéresse à l'effet du dispositif dit "Scellier" d'aide à l'investissement locatif privé sur le prix des terrains à bâtir. Notre méthode d'évaluation se situe dans le cadre de l'évaluation contrefactuelle d'une politique publique développée par Rubin. Nous mettons en...

This paper examines whether the subjective well-being of migrants is responsive to fluctuations in macroeconomic conditions in their country of origin. Using the German Socio-Economic Panel for the years 1984 to 2009 and macroeconomic variables for 24 countries of origin, we exploit country-year...

We consider a general control problem with two types of optimal regime switch. The first one concerns technological and/or institutional regimes indexed by a finite number of discrete parameter values, and the second features ecological-like regimes relying on given threshold values for given...
