We study a multiproduct pricing problem in which the prices of the products are restricted to discrete and finite sets. The demand for a product is a function of the prices of all the products. The prices of the products can be changed through time, subject to the aggregate consumption of each...

This paper develops a model of competition among multiproduct retailers that is consistent with observed pricing regularities, e.g., virtually all products have large mass points in their price distributions and most deviations fall below the mass point. The basis of the model is that, because...

We assess empirically the micro-foundations of producers' sticky pricing behaviour. The intertemporal profit function considered accounts for various functional forms of menu costs. The focus is on the analysis of multiproduct plants, and the menu costs therefore also allow for economies of...

The effects on a multi-product monopolist's pricing and bundling decisions of a form of regulation in which a price-cap is imposed on only the basic level of service is studied. Conditions are given under which the screening problem faced by the multi-product monopolist can be adequately...
