We study imperfect and monopolistic competition with asymmetric preferences over a variety of goods provided by heterogeneous firms. We show how to compute equilibria through the Morishima elasticities of substitution. Simple pricing rules and closed-form solutions emerge under monopolistic...

We study monopolistic competition under indirect additivity of preferences. This is dual to the Dixit-Stiglitz model, where direct additivity is assumed, with the CES case as the only common ground. Other examples include (perceived) demand functions that are exponential or linear. Our...

We study monopolistic competition with asymmetric preferences over a variety of goods provided by heterogeneous firms and show how to compute equilibria (which approximate Cournot and Bertrand equilibria when market shares are negligible) through the Morishima measures of substitution. Further...

We investigate what kind of competitive pressure induces existing firms to engage in more intensive innovation activities. We examine two types of competitive pressure: a price decrease in competitive fringe firms and a quality improvement therein. We use an oligopoly model with vertical...

We consider a downstream oligopoly model with one dominant and several fringe retailers, who purchase a manufacturing product from a monopoly supplier. We then examine how the supplier's outside option influences the relation between the dominant retailer's bargaining power and the equilibrium...

Recent years have seen growing cases of data-driven tech mergers such as Google/Fitbit, in which a dominant digital platform acquires a relatively small firm possessing a large volume of consumer data. The digital platform can consolidate the consumer data with its existing data set from other...

We provide a simple model to investigate decisions on vertical integration/separation. The key feature of this model is that more than one input is required for the final products of the local downstream monopolists. Depending on their cost structure, downstream firms' decisions on vertical...

We consider a bilateral monopoly in which a manufacturer can open its direct channel that is less efficient than the existing retailer. We find the following results. The manufacturer opens its direct channel if its bargaining power over the existing retailer is weak. Opening the direct channel...

We discuss the effect of personalized pricing on profits and welfare in a Hotelling model in which consumers can simultaneously purchase from both firms. We have the following results. If the additional gain from the second purchase (henceforth, the additional gain) is small, personalized...
