This paper first presents the optimal conditions for strategic R&D investment policy in the cases of noncooperative and cooperative R&D investment policies with international rivalry. Then we deal with a model of strategic product (i.e., quality-improving) R&D investment competition. In...

Applying a standard model of endogenous quality choice to the case of multiple national markets (i.e., a developed and a less developed country), we consider the effect of an economic integration (i.e., a movement from segmented markets into a single integrated market through the removal of...

Introducing product compatibility associated with network externalities (hereafter, network compatibility effects) into a horizontally differentiated duopoly model, we consider how network compatibility effects and the level of product substitutability affect endogenous timing decisions in the...

We examine whether free trade is superior to tariff policy if the government of an importing country cannot precommit to an ex ante optimal tariff rate in the presence of a time lag between production and trade decisions. Based on a simple partial equilibrium model with an export monopoly, we...

Employing the price-quality competition model in a horizontally differentiated products market, we analyze how a demand spillover effect associated with upgrading the quality level of a product affects the strategic relationship between firms and the property of a subgame perfect Nash...

It has been shown that trade restrictions such as tariffs, import quotas, and voluntary export restrictions, lead to quality upgrading of imports. In this paper, however, we reconsider this proposition by focusing on the nature of cost functions. Based on a standard vertical differentiation...

This paper discusses the timing and the optimal trade policy in the presence of oligopolisitic industries and free entry. Collie (1994) proved that an importing government should not commit a countervailing duty in response to a foreign export subsidy. We show that his main conclusion does not...

This paper analyses whether laissez faire is superior to tariff protection in the long-run, provided that the government of an importing country cannot precommit to an ex ante optimal tariff rate. We consider the cases of perfectly competitive foreign exporters and a monopolistic foreign...
