This paper demonstrates how three important results in environmental economics, true under mild conditions in closed economies, are false or need serious amendment in a world with international trade in goods. Since the three results we highlight have framed much of the ongoing discussion and...

We study models of credit with limited commitment, which implies endogenous borrowing constraints. We show that there are multiple stationary equilibria, as well as nonstationary equilibria, including some that display deterministic cyclic and chaotic dynamics. There are also stochastic...

Transportation costs are an important topic in international trade, but seldom have researches paid attention to general equilibrium trade modelling with transportation costs and explored their relevant effects. This paper uses different numerical general equilibrium trade model structures to...

Primary commodities are used as inputs into all production processes, yet they account for approximately 16 percent of world trade. Despite their share in trade, we show that the aggregate gains from trade are largely understated if we ignore key features of commodities: low price elasticities...

We provide an equilibrium analysis of the efficiency properties of bilateral tariff negotiations in a three-country, two-good general equilibrium model of international trade when transfers are not feasible. We consider "weak-rules" settings characterized by two cases: a no-rules case in which...

We study a non-parametric class of neoclassical trade models with global production networks and arbitrary distortions. We characterize their properties in terms of sufficient statistics useful for growth and welfare accounting as well as for counterfactuals. Using these sufficient statistics,...

Conventional analysis in the trade-industrial-organization literature suggests that, when a country has some market power over an imported good, some small level of protection must be welfare improving. This is essentially a terms-of-trade argument that is reinforced if the imported goods are...
