Structural models can assess the effectiveness of fishery management prospectively and retrospectively. However, when only fishery-dependent data are available, structural econometric models are highly nonlinear in the parameters, and maximum likelihood and other extremum-based estimators can...

Marine ecologists warn that humans are "fishing down marine food webs." To explore the economic implications of this phenomenon, this paper applies portfolio theory to aggregate fisheries data. It poses two definitions of a sustainable mean-variance catch frontier. It computes a mean-variance...

This paper outlines an empirical bioeconomic model that is spatially explicit. It combines a metapopulation model of sea urchin biology with a discrete choice econometric analysis of harvester behavior. Discrete choice results are used to simulate short-term spatial closures in the fishery, and...

The rise of ecosystem management as an approach to renewable resource policy increases the demand for empirical bioeconomics. This paper provides a working definition of bioeconometrics and a taxonomy of model types. A bioeconometric model is a structural model that econometrically estimates one...
