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...

This paper investigates the provision of insurance to workers against search-induced wage uctuations. I rely on numerical simulations of a model of on-the-job search and precautionary savings. The model is calibrated to low skilled workers in the U.S.. The extent of insurance is determined by...

This paper gives estimates of sectoral markup trends over the last three decades. It concludes with a slight increase of price-cost margins overall, contrary to the generally expected effect of increased competition. More strikingly, it establishes a clear pattern of markup convergence across...

This paper gives estimates of sectoral markup trends in thirteen OECD countries over the last three decades. It concludes with a slight, albeit heterogeneous, increase in price-cost margins (PCMs) overall, contrary to the generally expected effect of increased competition. More strikingly, it...

This paper examines the role of the labour share in creating instability in a small open economy. We assume that financial markets are imperfect so that entrepreneurs are credit constrained, and that this constraint is tighter for low levels of financial development. Aghion, Bacchetta and...

A large literature has studied the impact of labour market institutions on wage inequality, but their effect on income inequality has received little attention. In this paper we argue that personal income inequality is a function of the wage differential, the labour share, and the unemployment...
