This paper develops a dynamic game model of an asymmetric oligopoly with a renewable resource to reconsider welfare effects of increases in the number of firms. We show that increasing not only the number of inefficient firms but also that of Efficient firms reduces welfare, which sharply...

We revisit voluntariness of voluntary export restraints (VERs) in a differential game model of duopoly with sticky prices. We show that a VER set at the free trade level has no effect on equilibrium under open-loop strategies while the same policy results in a smaller profit for the exporting...

This paper formulates a reciprocal market model of international duopoly with network externalities to reconsider welfare effects of reductions in transport costs and tariffs. Depending on the magnitude of network externalities, we show two possibilities. One of them, which emerges under strong...

The literature on strategic environmental policy has not fully addressed welfare effects of trade liberalization from autarky. In a reciprocal market model of duopoly with transboundary pollution, we study how reductions in transport costs and import tariffs affect the Nash equilibrium welfare...

Formulating a dynamic game model of a world exhaustible resource market, this paper studies welfare implications of Stackelberg leaderships for an individual country and the world. We overcome the problem of time-inconsistency by imposing a \credibility condition" on the Markovian strategy of...

This paper explores some implications of the comparison between feedback Nash and Stackelberg equilibria for growth and welfare in a `voracity' model. We show that as compared to the Nash equilibrium, the Stackelberg equilibrium involves a lower growth rate while it leaves both the leaders and...

Recent empirics report that transport cost reductions signicantly contribute to rapidly growing world trade. This paper develops a reciprocal market model of intra-industry trade with transboundary pollution from consumption to consider how market integration in the form of transport cost...

This paper develops a reciprocal market model of international duopoly with transboundary pollution from consumption to examine the effects of bilateral tariff reductions on the equilibrium pollution tax and welfare. We show that tariff reductions induce each country to raise an emission tax and...

Recent empirics suggest the relevance of transport cost reductions for world trade growth along with eliminations in protectionist trade barriers. To address the welfare effects of trade cost reductions in a context of `trade and the environment,' we develop a two-stage game model where...

This paper, in a two-country duopoly model, compares destination- and origin-based commodity taxes in a context of a unilateral tariff-tax reform that fixes the world price and foreign welfare. We find that the proposed reform reduces domestic welfare, and hence is strictly Pareto-deteriorating...
