I distinguish between reduction offsets and removal offsets, the former generated by a reduction in the rate of greenhouse gas emissions and the latter generated by the removal of greenhouse gases from the atmosphere. I show that only removal offsets make any contribution to mitigating climate...

The main argument in favor of markets in environmental contexts is the same as in other contexts: their ability to promote efficient allocations and production. But environmental problems bring their own challenges: their underlying bio-physical processes - and the technologies to monitor them -...

We study how the strength of property rights to individual extractive firms affects a regulator's choice over exploitation rates for a natural resource. The regulator is modeled as an intermediary between current and future resource harvesters, rather than between producers and consumers, as in...

Property rights are commonly touted as a solution to common pool resource problems. But in practice the security of these property rights varies substantially owing to differences in design. In fisheries, the design of individual transferable quotas (ITQs) varies widely; the consequences of...

We show that grandfathering fishing rights to local users or recognizing first possessions is more dynamically efficient than auctions of such rights. It is often argued that auctions allocate rights to the highest-valued users and thereby maximize resource rents. We counter that rents are not...

This paper analyzes the medium to long-term implications of global warming for the evolution of global financial structures. Stern (2007) and other related scientific literature reports that greenhouse gas emissions generated by human activities will very possibly lead to global temperature...

Over the past two decades international markets have become more open, leading to a common perception that global capital markets have become more integrated. In this paper, I ask what this integration and its resulting higher correlation would imply about the diversification potential across...

Within-country ethnic diversity in high-wage immigrant nations is driven by long distance migration. This paper documents the migration-diversity connection for the first global century before 1914 and the second global century after 1950. It distinguishes between ethnic diversity among the...

One possible explanation for home bias is that investors may obtain indirect international diversification benefits by investing in multinational firms rather than by investing directly in foreign markets. This paper employs mean-variance spanning tests to examine the diversification potential...
