We propose a methodology for estimating the competition effects from entry when firms sell differentiated products. We … first derive precise conditions under which Bres- nahan and Reiss'entry threshold ratios (ETRs) can be used to test for the … presence and to measure the magnitude of competition effects. We then show how to augment the traditional entry model with a …

We introduce a new measure of competition: the elasticity of a firm’s profits with respect to its cost level. A higher value of this profit elasticity (PE) signals more intense competi- tion. Using firm-level data we compare PE with the most popular competition measures such as the price cost...

This paper studies the consequence of an imprecise recall of the price by the consumers in the Bertrand price competition model for a homogeneous good. It is shown that firms can exploit this weakness and charge prices above the competitive price. This markup increases for rougher recall of the...

The liberalization of the electricity sector increases the need for realistic and robust models of the oligopolistic interaction of electricity firms. This paper compares the two most popular models: Cournot and the Supply Function Equilibrium (SFE), and tests which model describes the observed...
