We demonstrate the possibility of shake-out of firms and emergence of inter-firmheterogeneity along the (socially optimal) dynamic equilibrium path of a competitive industry with freeentry and exit, even when there is no uncertainty and all firms are ex ante identical with perfectforesight....

In this article we study patterns of vertical product differentiation in a multi-product monopoly using a random utility model. Prior research shows that applying such a model in a multi-product setting implies symmetric patterns of product differentiation in which all product variants of a...

This discussion paper resulted in a publication in <I>European Economic Review</I> (2014), 164-180.<P> We analyze the impact of product bundling in experimental markets. One firm has monopoly power in a first market but competes with another firm in a second market. We compare treatments where the...</p></i>

This paper studies the relationship between three key elements of the marketing mix, namely, price, product, and promotion, in a model where a seller employs informative advertising to launch a new product. We propose a fairly general advertising technology for the study of three promotional...

We develop a method to screen for local cartels. We first test whether there is statistical evidence of clustering of outlets that score high on some characteristic that is consistent with collusive behavior. If so, we determine in a second step the most suspicious regions where further...
