We study business cycles with cyclical returns to scale. Contrary to tightly parameterized production functions (Cobb-Douglas and Constant Elasticity of Substitution), we empirically identify strong input complementarity that leads to procyclical returns to scale. We therefore propose a flexible...

The aim of this paper is to assess the impact of the interbank market on the business cycle fluctuations. In order to do that, we build a DSGE model with heterogeneous households and banks. The surplus bank can allocate its resources between interbank lending and risk free government bonds. This...

The aim of this paper is to assess the impact of the interbank market on the business cycle fluctuations. We build a DSGE model with heterogeneous households and banks. Two kind of banks are in the model: Deficit banks which are net borrowers on the interbank market and they provide credit to...

This paper studies the importance of firm-level price markup dynamics for business cycle fluctuations. Using state-of-the-art IO techniques to measure the behavior of markups over the business cycle at the firm level, I find that markups are countercyclical with an average elasticity of -1.1...
