While public investment in conservation such as the Conservation Reserve and Wetlands Reserve Programs have improved the environmental state of the lands, they have not provided an institutional means for production and profit expansion for the same acreage. This type of public investment places...

Scientific evidence suggests that economic activity is threatening global biodiversity in ways that could severely degrade nature's flow of ecosystem services. Yet, there is relatively little work in economics that addresses biodiversity loss. Some economists have called for better integration...

We characterize optimal fishery management in an age-structured, bio-economic model where two age groups are harvested with costly and imperfect selectivity. We show that a system of tradable fishing permits, each allowing to harvest a specific number of fish that differs with age group,...

Widespread global collapses of fisheries corroborate decades-old predictions by economists, made long before large-scale industrialization of the world's fisheries, that open access would have deleterious ecological and economic effects on fishery resources. Incentive-based alternatives...

Using data from what was once one of the world’s largest capture fisheries, the northern cod fishery, the economic value of a marine reserve is calculated using a stochastic optimal control model with a jump-diffusion process. Counterfactual analysis shows that with a stochastic environment an...

A serious problem facing fisheries managers is how to improve estimates of the distortion in stock assessments resulting from "fouling" of commercial catch data. We propose a simple analytical model of discarding and high-grading, and estimate the "data fouling factor"—the wedge between what...

We model adoption and diffusion in a commons under uncertainty about a technology’s value. Technological resource stock externalities make technology less valuable with depleted stocks, but transmit information about a new technology’s value, causing faster adoption of high-value technologies.
