The political agreement over management of transboundary pacific salmon reached in 1999 should be supplemented with economic incentives to help maintain cooperation between the U.S. and Canada.

Unintentional introductions of nonindigenous plants, animals, and microbes cause significant ecological and agricultural crop damage worldwide. Trade in both manufactured and agricultural goods is a primary vector for such introductions. Fusing simple models of trade and biological...

To what extent can private-sector bioprospecting incentives be relied upon for the protection of biological diversity? The literature contains dramatically different estimates of these incentives from trivial to quite large. We resolve this controversy by isolating the fundamental source of the...

The global demand for protein from seafood – whether wild, caught or cultured, whether for direct consumption or as feed for livestock – is high and projected to continue growing. However, the ocean’s ability to meet this demand is uncertain due to either mismanagement or, in some cases,...

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...

Adaptation to exogenous change occurs on both intensive and extensive margins. Whether and how one accounts for human adaptation directly affects estimates of the economic consequences of environmental change, estimates that are both critical in informing policy decisions and notoriously...

We analyze a policy experiment in an Alaskan commercial fishery that assigned a portion of an overall catch quota to a voluntary co-op, with the remainder exploited competitively by those choosing to fish independently. Unlike the individual quota system advocated by many economists, the policy...
