This paper uses a semi-parametric empirical model to estimate the economic benefitsof adopting a property rights-based management program in the Gulf of Mexico grouperfishery. The analysis predicts that a rights-based fleet will be comprised of fewer, morecost efficient boats than under the...

This paper studies equilibrium search and learning in a dynamic shing gamethat is played by independent shermen and by members of an information sharingCooperative. Once collected, information about the location of productive sh-ing sites is an excludable public good. We show that independent...

Models of fishing behavior rarely incorporate the complexities of marine ecosystems,multiple-stock harvest technologies, and regulations present in real world marinefisheries. We introduce a structural model of a multi-species, weak-output-disposabilityharvest technology. A latent...

This paper estimates a structural model of multiple-species harvesting costs in the easternGulf of Mexico reef fish fishery. The calibrated model is used to predict fleet size, vessellevelharvesting activity and fleet-wide revenues and costs that are expected under a proposedindividual fishing...

This paper considers the problem of multi-species fisheries managementwhen targeting individual species is costly and at-sea discards of fish by fishermenare unobserved by the regulator. Stock conditions, ecosystem interaction, technologicalspecification, and relative prices under which at sea...

Für Namibias Wirtschaft ergeben sich nach der Unabhängigkeit teilweise wenig erfreuliche Perspektiven. Die Fischfangergebnisse gehen zurück. Die Überfischung soll durch Fangquoten ausgeglichen werden. Beim Bergbau ist der Exportrückgang um real 30% im Vergleich zu 1989 ein alamierendes...

Die Rubrik »Kurz zum Klima« erscheint nun bereits seit drei Jahren mit nahezu 60 Ausgaben. Dieser Beitrag greift drei Themen aus den Bereichen Energie-, Klima- und Umweltpolitik – das Reserven-Produktions-Verhältnis, die weltweite CO2-Reduktion und das Problem der Überfischung – erneut...
