We study optimal fishery management in an age-structured, bio-economic model where two age classes can be harvested independently. We show that the optimal amount of catch differs with age classes, and we derive conditions under which it is optimal to harvest only one age class. Our main policy...

Despite growing environmental issues, and increasing public and private interests, scientific studies on the management of agroecosystem services are at the beginning stage. This article incorporates the interdisciplinary New Institutional Economics framework and identifies and assesses a...

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...

While public investment in conservation such as the Conservation Reserve and Wetlands Reserve Programs have improved the environmental state of the lands, they have not provided an institutional means for production and profit expansion for the same acreage. This type of public investment places...

Fishers in developing countries do not have the resources to acquire advanced technologies to exploit offshore fish stocks. As a result, the United Nations Convention on the Law of the Sea requires countries to sign partnership agreements with distant water fishing nations (DWFNs) to exploit...

The aim of this paper is to explain under which circumstances using TACs as instrument to manage a fishery along with fishing periods may be interesting from a regulatory point of view. In order to do this, the deterministic analysis of Homans and Wilen (1997)and Anderson (2000) is extended to a...

An economic expert working group (STECF/SGBRE-07-05) was convened in 2007 for evaluating the potential economic consequences of a Long-Term Management Plan for the northern hake. Analyzing all the scenarios proposed by biological assessment, they found that keeping the F in the status quo level...

We characterize optimal fishery management in an age-structured, bio-economic model where two age groups are harvested with costly and imperfect selectivity. We show that a system of tradable fishing permits, each allowing to harvest a specific number of fish that differs with age group,...

The illegal exploitation of wild abalone in South Africa has been escalating since 1994, despite increased enforcement, leading to collapse in some sections of its range. South Africa banned all wild abalone fishing in 2008 but controversially reopened it in 2010. This paper formulates a...

Sustainable food policies strive for environmental, healthy, economically just, and humane food production. Their success has ignited legal debates about the Constitution. This is not new. Iconic constitutional law cases examine sustainable food, such as meat in the Slaughter-House Cases (1873),...
