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...

A two-agent model of international trade with oligopoly and increasing returns is proposed to address why there have been persistent anti-trade-liberalization movements. It is shown that all of a country's residents lose from trade under certain conditions on the cross-country cost structure.

Constructing a model of polluting oligopoly with product differentiation, we consider how product differentiation, together with the presence and absence of free entry, affects optimal pollution tax/subsidy policies. The sign of the short- and long-run optimal pollution taxes are highly...

This paper reports an intriguing property of a nonlinear feedback Nash strategy equilibrium in a dynamic game with no state variable in the payoff of each player. While the open-loop Nash and linear feedback Nash equilibria coincide with the static Cournot-Nash equilibrium in such a framework,...

Constructing a two-good (a competitive and monopolized goods), two-primary factor (capital and labor) and two-country model of international trade where the monopolized sector is subject to increasing returns to scale, we establish an oligopolistic version of the Heckscher-Ohlin Theorem.

Constructing a two-country, two-good, two-factor model of international trade under quasi-linear utility functions, we obtain a Modified Heckscher-Ohlin (MHO) Theorem that relates the trade pattern to the international distribution of factor endowments. We also show that the MHO Theorem survives...

Constructing a two-good (competitive and imperfectly-competitive goods), two-primary factor (capital and labor) and two-country model of international trade where the imperfectly-competitive sector is subject to increasing returns to scale, we establish an oligopolistic version of the...

In this note we examine if the proposition offered by <link rid="b5">Fershtman and Nitzan (1991)</link> and <link rid="b12">Wirl (1996)</link> in the context of a dynamic voluntary provision model with a linear production function can be generalized to a more general CES formulation. By comparing the steady-state stocks of a public good in...
