We develop a balanced growth model with labor supply and search and matching frictions in the labor market to study the impact of economic policy variables on the two margins which constitute the (total) labor input: the extensive one (the rate of employment) and the intensive one (the hours...

We provide a quantitative assessment of welfare costs of fluctuations in a search model with financial frictions. The matching process in the labor market leads positive shocks to reduce unemployment less than negative shocks increase it. We show that the magnitude of this non-linearity is...

Gali et al. (2007) have recently shown in a quantitative way that inefficient fluctuations in the allocation of resources do not generate sizable welfare costs. In this note, we show that their evaluation underestimates the welfare costs of inefficient fluctuations and propose a biased estimate...
