Description:
"In common property resources such as the Gulf of Mexico shrimp fishery changes in economic and biological conditions affect the level of fishing effort applied by fisher- men. Since effort is maintained at that level where total costs are equal to total revenue at the margin, any increase in price or decrease in costs will result in an expansion of effort until the normal economic profits are dissipated. Effort levels can expand either as short or long run effects. In the short run, the variable factors of production such as crew size, days fished, or the amount or type of gear used can be altered to fit the new economic or biological conditions. In the long run, the fIXed factors of production such as vessel length, hull material, or engine horsepower can be adjusted. Vessel entry and exit behavior in the fishing fleet is caused by these long run adjustments in fishing effort. In an effort to better understand the causes of fleet size and structural change, a multidiscipline approach has been used in this technical report. Sections on economic theory, fisheries biology, statistical methodologies, and examples of their applications that relate to vessel entry and exit behavior have been incorporated in this report. For example, the probability that a given vessel would enter or exit the shrimp fishery would be a function of exvessel prices, input costs, and shrimp resource availability. To determine this probability would require the use of discrete choice modelling techni- ques in conjunction with the economic theories of production and fisheries as well as fisheries biology. It is hoped that the research summarized in this report will be of use to other researchers in this and related areas"--Introduction.
