I introduce sticky wages in the model with credit constrained or “rule of thumb” consumers advanced by Galì, Valles and Lopez Salido (2005). I show that wage stickiness i) restores, in contrast with the results in Bilbiie (2005), the Taylor Principle as a necessary condition for equilibrium...

We introduce Cournot competition and endogenous entry in an oth- erwise neoclassical macroeconomic framework. First, we develop a model with exogenous savings à la Solow describing the dynamic path of busi- ness creation. Then, we develop a model à la Ramsey describing the dynamic interaction...

We introduce endogenous strategic interactions under competition in quantities and in prices together with endogenous entry in a dynamic stochastic general equilibrium model with flexible prices. The endogenous mark ups depend on the form of competition and on the degree of substitutability...

This paper introduces a New Keynesian multi-sector industry model that integrates firm heterogeneity, entry, and exit dynamics, while considering energy production from both fossil fuels and renewables. We investigate the effects of a sustained increase in fossil fuel prices on sectoral size,...

We propose a flexible prices model where endogenous market structures and search and matching frictions in the labor market interact endogenously. The interplay between firms endogenous entry, strategic interactions among producers and labor market frictions represents a strong amplification...
