This paper studies the behaviour of firm entry and exit in response to macroeconomic shocks. We formulate a dynamic stochastic general equilibrium model with an endogenous number of producers. From the calibrated model, we derive a minimum set of robust sign restrictions to identify four kinds...

This paper evaluates how different lengths of entry regulation impact market structure and market performance using a dynamic structural model. We formulate an oligopoly model in the tradition of Ericson and Pakes (1995) and allow entry costs to vary over time. Firms have the opportunity to...

We focus on the estimation of market entry costs that are declining over time and evaluate their impact on competition and market performance. We employ a dynamic oligopoly model in which firms make entry, exit, and production decisions in the presence of declining entry costs and learning by...

The paper inquires whether a public eco-label mitigatesadverse selection, where an ecologically superior (green) product variant is underprovided. A model, integrating entry into a perfectly competitive, vertically differentiated industry and rationally expected quality structure (REQS) under...
