The seafood market has changed substantially in recent decades, becoming increasingly globalized. This has led to introduction of new species and new sources of fish in most markets. We estimate a seafood demand system that, unlike models in previous studies, accounts for potential structural...

This paper deals with estimation of a production technology where endogeneous choice of input and output variables is explicitly recognized. In particular, we assume that producers maximize return to the outlay (RO). For simplicity and tractability we start with a Cobb–Douglas transformation...

We analyze the Gulf of Mexico brown shrimp fishery and the potential impacts of a large seasonal area of hypoxia (low dissolved oxygen) that coincides with the peak shrimp season. A spatial-dynamic bioeconomic simulation embeds three biological impacts on shrimp: mortality, growth, and...

This study deals with modeling of production risk by means of a two-step procedure. In contrast to earlier studies of production risk, we do not immediately adopt restrictive functional forms for the risky production technology. We first test for the presence of production risk. If production...

After holding a market share of over 50% for farmed salmon in USA, the market was closed for Norwegian salmon in 1991 when a countervailing duty was imposed. The objective for U.S. farmers was to increase prices and U.S. market shares. This paper investigates whether U.S. farmers reached these...

A number of papers have discussed the relationship between the Almost Ideal Demand System (AIDS) and its linear approximation (LA/AIDS). In this paper, it is shown that if the prices in the system are normalized to one, the AIDS and LA/AIDS representations are identical at the point of...

Relationships between prices of goods offer motives of interest in at least two areas: market integration and product aggregation. There is a close relationship between market integration and aggregation, which may increase the usefulness of market integration studies. In this article, these...

Aquaculture production has increased rapidly during the last three decades. This is due toincreased production of established species as well as a continuous introduction of newspecies. Productivity growth is the main engine for the increased production in aquaculture,and as the accumulated...
