In this paper, we argue that credit market imperfections impact not only the level of unemployment, but also its persistence. For this purpose, we first develop a theoretical model based on the equilibrium matching framework of Mortensen and Pissarides (1999) and Pissarides (2000) where we...

Short-term increasing returns to production factors are usually found in empirical studies. We argue they can be due to omitted variables, particularly the intensity of factor utilisation. Thanks to original French firm-level data (1992-2008), we show how increasing returns to scale disappear...

In this paper, we develop a model of innovation-based growth to address the issue of skill-biased technical change over the long run. We show that innovations fluctuate endogenously from skilled to unskilled sectors, thereby generating periods of increasing and decreasing wage inequality. This...

We estimate the responses of gross labor income with respect to marginal and average net-oftax rates in France over the period 2003-2006. We exploit a series of reforms to the income-tax and payroll-tax schedules affecting individuals who earn less than twice the minimum wage. Our estimate for...

We investigate how potential tax-driven migrations modify the Mirrlees income tax schedule when two countries play Nash. The social objective is the maximin and preferences are quasilinear in income. Individuals differ both in skills and migration costs, which are continuously distributed. We...

This paper argues that, for a given overall level of labour income taxation, a more progressive tax schedule reduces the unemployment rate and increases the employment rate. From a theoretical point of view, higher progressivity induces a wage-moderation e ect and increases overall employment...

La coexistence de trois dispositifs massifs de réduction du coût du travail, les exonérations générales de cotisations employeurs, le Crédit d'Impôt pour la Compétitivité et l'Emploi, et le " pacte de responsabilité " dont la mise en place a été annoncée au début 2014, n'est pas un...
