We analyze the decisions of foreign-born PhD and postdoctoral trainees to come to the United States vs. go to another country for training. Data are drawn from the GlobSci survey of scientists in sixteen countries working in four fields. We find that individuals come to the U.S. to train because...

This paper explores the link between mobility and the presence of international research networks. Data come from the GlobSci survey of authors of articles published in 2009 in four fields of science working in sixteen countries. Summary evidence suggests that migration plays an important role...

Country incentives to participate in cooperative arrangements which either fully or partially internalize climate change externalities from carbon emissions involve critical asymmetries. Small countries trade off own country costs of carbon mitigation actions against their own benefits from...

An estimate of the social cost of carbon (SCC) is key to climate policy. But how should we estimate the SCC? A common approach is to use an integrated assessment model (IAM) to simulate time paths for the atmospheric CO2 concentration, its impact on global mean temperature, and the resulting...

This paper develops a theoretical foundation for the social cost of carbon (SCC). The model highlights the source of debate over whether countries should use the global or domestic SCC for regulatory impact analysis. I identify conditions under which a country's decision to internalize the...

With few exceptions, economic analyses of "cap-and-trade" permit trading mechanisms for climate change mitigation have been based on first-best scenarios without pre-existing distortions or regulations. The reason is obvious: interactions between permit trading and other regulations will be...

Case studies suggest that Marine Protected Areas (MPAs) can be effective tools for fishery management. This study uses global datasets of MPAs and stock assessments to estimate the strength and robustness of their benefits. We apply multiple models, including a treatment-control pairing, a...

The last decade has witnessed an explosion in the number of regional trade agreements (RTAs). There seems to be a general if ill-defined belief on the part of many policy-makers, and among a number of academics as well, that there is more to a RTA than the traditional gains from trade. This...
