Abstract or Summary
  • We present the outlines of an integrated economic-ecological framework designed to help assess the implementation of the ecosystem-based management (EBM) of fisheries in New England. We develop the framework by linking a computable general equilibrium (CGE) model of a coastal economy to a bottom-up model of a marine food web for Georges Bank. We focus on the New England region using coastal county economic data for a restricted set of industry sectors and marine ecological data for three top level food web components: planktivores, benthivores, and piscivores. We undertake numerical simulations to model the welfare effects of changes in alternative combinations of species (or guild) yields and alternative manifestations of biological productivity. We estimate the distributional effects of alternative simulations across a range of consumer income levels. This framework could be used to extend existing methodologies for assessing the impacts on human communities of groundfish stock rebuilding strategies, such as the imminent sector management program in the US northeast fishery management region. We discuss other possible applications of and modifications and limitations to the framework.
