The hemlock woolly adelgid is an invasive insect that is damaging hemlock forests in the eastern United States. Several control methods are available but forest managers are constrained by cost, availability, and environmental concerns. As a result forest managers must decide how to allocate...

The management of non-native invasive species is a complex but crucial task given the potential for economic and environmental damages. For many invasions the development of socially optimal control strategies requires more than is offered by the single-species, single-control models that have...

As atmospheric carbon dioxide (CO2) concentrations increase, the world’s oceans are absorbing CO2 at a faster rate than at any time in the past 800,000 years. While this reduces the amount of the most prevalent greenhouse gas in the atmosphere it also causes changes in seawater chemistry,...

The “social cost of carbon” (SCC) is the present value of the future stream of damages from one additional ton of carbon emissions in a particular year. This paper develops a simple model for calculating the SCC and compares estimates of the SCC under certainty and uncertainty. Our model...
