Constructing a model of oligopoly with free entry, this paper examines the effects of a tariff reduction accompanied with a unit of consumption tax increase on welfare, government revenue, and market access. We show that the suggested policy reform reduces welfare while enhancing government...

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...

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...

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...

Constructing a duopoly model with non-constant marginal costs and a strict Pareto criterion, this paper examines welfare effects of world-price-fixing tariff reductions accompanied by adjustments of a domestic tax. If a destination-based consumption tax is used, this reform achieves a strict...

We construct an exporting monopoly model to compare destination- and origin-based commodity taxes in a context of a trade and domestic tax reform. We show that an export tax reduction and a change in destination (resp. origin) tax that fix the world price is strictly Pareto-improving (resp....
