We consider the welfare effects of skilled worker emigration in a context where skilled labor plays a role in product design. We show such emigration can benefit the residents left behind, even when consumers’ tastes exhibit a form of home bias. This is because emigration improves the design...

We introduce international mobility of knowledge workers into a model of Nash equilibrium IPR policy choice among countries. We show that governments have incentives to use IPRs in a bidding war for global talent, resulting in Nash equilibrium IPRs that can be too high, rather than too low, from...

NAFTA’s investment treaty has led to several expropriation compensation claims from investors hurt by new environmental regulations. Expropriation clauses in international treaties solve post-investment moral hazard problems such as hold-ups. However, these clauses can interact with...

We show that harmonizing emissions policy may be bad for the environment and/or global welfare, even when pollution is transboundary and countries are identical in every way. Harmonization effectively internalizes the transboundary aspects of pollution. But it also hampers producers’...

Unintentional introductions of non-indigenous plants, animals, and microbes cause significant ecological and agricultural crop damage worldwide. There is an emerging empirical link between international trade and the frequency and damage of such introductions. We explore the effects of domestic...

In this comprehensive reference work, Kevin Gallagher has compiled a fresh and broad-ranging collection of expert voices commenting on the interdisciplinary field of trade and the environment. For over two decades policymakers and scholars have been struggling to understand the relationship...

We consider the welfare effects of skilled worker emigration in a context where skilled labor plays a role in product or process design. We show such emigration can benefit the residents left behind, even when consumers' tastes exhibit a form of home bias. This is because emigration improves the...

We employ a stylized model of trade in dirty intermediate goods to examine the impacts of product standards on trade volumes and pollution levels. Our focus is on the case with economies of scale in intermediate good production. In this setting, changes in one country's demand for dirty inputs...

We consider the welfare effects of the emigration of workers who produce a public good (knowledge). We distinguish between the knowledge diversion and knowledge creation effects of such emigration, and show that the remaining residents of a country can gain from emigration, even when tastes for...
