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...

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...

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),...

The effects of six common forms of fisheries support are estimated using a bioeconomic model of the global fishery. The results show that all have the potential to provoke overfishing, to lead to fish stocks being overfished, to encourage illegal, unreported or unregulated (IUU) fishing and to...

The Klamath River, draining some 12,000 square miles in southern Oregon and northern California, was once the third largest salmon stream on the West Coast, the life force of Native Americans. The river runs 263 miles from headwaters in Oregon and flows through the Cascades to the Pacific Ocean...

This paper examines how fisheries policies affect domestic versus foreign fishing efforts. In line with previous work, the paper finds that policies directly affecting fishing costs (e.g. fuel or input subsidies) are more likely to lead to overfishing than those based on income or fixed assets...

In this study, we investigate whether neoclassical economic theory, capital market frictions or preference-based theory can explain investment behaviour in the Dutch beam trawler fishery in the North Sea. By presenting a number of estimations, we show that vessels conducting pulse fishing invest...

We develop a bioeconomic model to analyze a sole-owner fishery with fixed costs as well as a continuous cost function for the generalized Cobb-Douglas production function with increasing marginal returns to effort level. On the basis of data from the North Sea herring fishery, we analyze the...
