Economic theory predicts that the least-efficient vessels are more likely to exit a fishery following the transition to an individual transferable quota (ITQ) management regime. Tools are needed to help analysts predict the likely degree and distribution of consolidation prior to implementing...

This paper investigates the factors affecting the demand for crop–hail insurance and explores the potential relation with pesticide use for a sample of French farmers on the period 1993-2004, for the Meuse department. An econometric model involving two simultaneous equations with mixed...

Delineation of the relevant market forms a pivotal part of most antitrust cases. The standard approach is sequential. First the product market is delineated, then the geographical market is defined. Demand and supply substitution in both the product dimension and the geographical dimension will...

The increasing share of imported food in developed countries, such as the U.S. and European Union countries, poses new challenges for food safety and quality regulators. China as the world's biggest food producer has the fastest growing share of fish and shellfish exports to these countries....

Case studies suggest that Marine Protected Areas (MPAs) can be effective tools for fishery management. This study uses global datasets of MPAs and stock assessments to estimate the strength and robustness of their benefits. We apply multiple models, including a treatment-control pairing, a...

This paper develops an optimal harvesting model for the wild Atlantic salmon (Salmo salar), where various age classes of the population are included. It is shown that the marginal value–fecundity relationship of the spawning population, comprising young and old fish, is crucial for the optimal...

The purpose of this paper is to examine the choice of currency for Norwegian salmon exporters. The choice of invoicing currency will affect prices in different markets as well as risk, factors that are becoming increasingly important as the supply chain for salmon is becoming more sophisticated,...

Understanding the eect of introducing property rights to natural resources is central in economics, but empirical analysis is frustrated by the complexity of socioecological systems. We construct a detailed bio-economic model of the Norwegian coastal cod shery, which was closed after 1989, to...

The WTO members are conducting negotiations to clarify and improve disciplines on fisheries subsidies at the Doha Round. In this paper, I investigate how worldwide subsidy reform in the fisheries sector could affect fisheries output and resource stocks in a trading equilibrium. I demonstrate...

Individual transferable quotas (ITQs) induce changes along the 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...
