We build on the latest developments in the structural gravity literature to quantify the partial and general equilibrium effects of GATT/WTO membership on trade and welfare. Using an extensive database covering manufacturing trade for 186 countries over the period 1980-2016, we find that the...

In a three-country model of endogenous trade agreements, we study the implications of the Most Favored Nation Clause (MFN) when countries are free to form discriminatory preferential trade agreements (PTAs). While PTA members discriminate against non-member countries, MFN requires non-members to...

We analyze how a country pursuing a unilateral climate policy may contribute to a reduction in global CO2 emissions in a cost-effective way. To do so its system of energy taxes and subsidies must account for leakage of emissions from the domestic to the foreign economy. We focus on leakage...

We consider an international cartel whose members interact repeatedly in their own as well as in third-country segmented markets. Cartel discipline-an inverse measure of the degree of competition between firms-is endogenously determined by the cartel's incentive compatibility constraint (ICC),...

Using a unique plant-level dataset we examine total factor productivity (TFP) growth and its components, related to efficiency change and technical change. The data we use is from Sweden and for their pulp and paper industry, which is heavily regulated due to its historically large contribution...

What is a feasible and efficient policy to regulate air pollution from vehicles? A Pigouvian tax is technologically infeasible. Most countries instead rely on exhaust standards that limit air pollution emissions per mile for new vehicles. We assess the effectiveness and efficiency of these...

We develop a spatial equilibrium model to evaluate the efficiency and distributional impacts of the leading air quality regulation in the United States: the National Ambient Air Quality Standards (NAAQS). We link our economic model to an integrated assessment model for air pollutants which...

Repeated interactions provide a prominent but paradoxical hypothesis for human cooperation in one-shot interactions 1–3. Intergroup competitions 4–7 provide a different hypothesis that is intuitively appealing but heterodox. We show that neither mechanism reliably supports the evolution of...

In an interconnected world, economic and political interests inevitably reach beyond national borders. Since policy choices generate external economic and political costs, foreign state and non-state actors have an interest in inflencing policy actions in other sovereign countries to their...

We study the welfare impact of rules of origin in free trade agreements where final-good producers source customized inputs from suppliers within the trading bloc. We employ a property-rights framework that features hold-up problems in suppliers’ decisions to invest, and where underinvestment...
