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...

Taking technological differences between firms as given, we show that the technologically advanced firm has a stronger incentive for technology licensing under a decentralized unionization structure than with centralized wage setting. Furthermore, We show that, in presence of licensing, the...

We show that the presence of a strategic tax policy increases the incentive for a horizontal merger compared to the situation with no tax policy. Thus, we point towards a new factor, viz., strategic tax policy, for increasing the incentive for a horizontal merger that has been ignored in the...

We study the implications of credit constraints for the sustainability of product market collusion in a bank-financed oligopoly in which firms face an imperfect credit market. We consider two situations, without and with credit rationing, i.e., with a binding credit limit. When there is credit...

We consider the plant location decision of a multinational corporation (MNC), which has the option to invest in a more or in a less technologically lagging country, and which aims to use its foreign plant as an export-platform. We show that the plant location decision of the MNC depends on...

This paper challenges the conventional wisdom that exclusive owners of an advanced technology are always better off when producing as a monopolist than when competing against another firm. Competition against a less efficient firm weakens the power that a host country can exert on the incumbent...

We show that the presence of a strategic tax policy increases the incentive for a horizontal merger compared to the situation with no tax policy. Thus, we point towards a new factor, viz., strategic tax policy, for increasing the incentive for a horizontal merger that has been ignored in the...

We provide a unified approach to imperfect (monopolistic, Bertrand and Cournot) competition equilibria with demand functions derived from symmetric preferences over a large but finite number of goods. The equilibrium markups depend on the Morishima Elasticity of Substitution/Complementarity...
