The expansion of wind-generation in the United States poses significant challenges to policy-makers, particularly because wind's intermittency and unpredictability can exacerbate problems of congestion on a transmission-constrained grid. Understanding these issues is necessary if optimal...

This paper develops an optimal harvesting model for the wild Atlantic salmon (Salmo salar), where various age classes of the population are included. It is shown that the marginal value–fecundity relationship of the spawning population, comprising young and old fish, is crucial for the optimal...

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,...

In this paper we undertake a systematic investigation of instrument choice when preventing a population collapse rather than maximizing industry profit is the overriding concern. Contrary to what seems to be the general consensus we find that landing fees do provide more effective insurance...

We bridge the non-market microeconomic recreational demand and bioeconomic modeling literatures by constructing a dynamic model to guide optimal management of recreational fisheries. Our model incorporates multiple forms of angler heterogeneity and directly models feedbacks between policy...

National-level strategies for reducing emissions from deforestation and degradation (REDD), financed by international transfers, have begun to emerge. A three-sector model is developed to explore the economy-wide effects of two policies implemented by a government participating in REDD that...

Improving information about individual opportunity costs of deforestation agents has the potential to increase the efficiency of REDD when it takes the form of a payment for environmental services scheme. However, objectives pursued in REDD projects may vary across policy makers. Within a...

We explore the optimal time path of carbon sequestration and carbon abatement in stabilizing CO2 levels under uncertainty of climate impacts. Using a two-period sequential decision making model, we analytically derive optimal rates for the two control variables, abatement and sequestration...

Bio-energy with carbon capture and sequestration (BECCS) has the potential to be a key mitigation option, because it can generate electricity and absorb emissions at the same time. However, biomass is not distributed evenly across the globe and regions with a potentially high demand might be...

Bio-invasions occur in management mosaics where local control affects spread and damage across political boundaries. We address two obstacles to local implementation of optimal regional control of a bio-invasion that damages public and private resources across jurisdictions: lack of local funds...
