Individual transferable quotas (ITQs) induce changes along both the extensive margin—via consolidation of quota among fewer vessels—and the intensive margin, as harvesters adjust their behavior to ITQ incentives. We use ITQ introduction in the Bering Sea crab fishery to decompose the sources...

Danube Delta has suffered damages of habitat and species loss caused by factors, including: construction of dams upstream have degraded obviously flooding regime; creation of agricultural and fishing enclosures which decreased the natural and original surfaces; extending artificial navigation...

The problem of the commons is more important to our lives and thus more central to economics than a century ago when Katharine Coman led off the first issue of the American Economic Review. As the U.S. and other economies have grown, the carrying-capacity of the planet--in regard to natural...

Game-theoretic models of fisheries typically consider cases where some players harvest a single common fish stock. However, these types of models do not capture many real-world mixed fisheries, where species can be biologically independent or dependent. The present paper considers cases where...

Fisheries economics stand on the cusp of potentially sizeable changes in orientation and policy focus, leading in turn to comparable changes in modeling and general analysis. Notably, fisheries are increasingly framed as part of the overall marine environment rather than considered as solely or...

La gestión eficiente de ciertos recursos renovables caracterizados por la propiedad común y el libre acceso ha estado mediatizada por la denominada «Tragedia de los Comunes». La literatura pionera en este campo enfatizaba la necesidad de un marco regulatorio que superara esta tendencia hacia...

Las políticas basadas en la concesión de subsidios a sectores económicos concretos, y entre ellos al sector pesquero, se han generalizado durante los últimos cincuenta años y a pesar de su dilatada historia, no se ha llegado a alcanzar un consenso sobre su alcance y efectos. El análisis...

As an alternative to the more traditional fixed-price schemes, governments can run auctions to purchase environmental services from private agents. Governments have so far chosen the discriminatory price (DP) over the uniform price (UP) format. Theoretical and experimental studies have concluded...

In this paper we use a general model of imperfect competition to predict welfare changes within an open-access fishery after it transitions to individual transferable quota (ITQ) management. Although related research has explored the effects of market power in the harvesting sector on ITQ...

The paper sets up a four-stage enforcement model of fish quotas. The purpose of the paper is to show how the level of enforcement set by the authorities af-fects the way fishermen form coalitions. We show that a high level of control effort yields less cooperation among fishermen, while in the...
