| The goal of this study was to produce a detailed aquaculture production model incorporating constraints unique to closed system culture and to conduct a formal economic analysis of closed system operation. Results generated by this model indicate that less than perfect management ability can eliminate the normal advantages associated with using high protein feed. While higher protein levels produce faster growth, and for this reason are often used in the industry, the increased direct feed costs and indirect costs due to metabolic feedbacks produce lower daily returns if high protein feed use continues through harvest. This model showed that inefficiency in solids removal negatively affects returns, but the majority of negative impacts were linked to... |

| Coastal wetland loss has been a major problem in Louisiana, exceeding 1.2 million acres over the last century alone. Although federal, state, and local efforts have attempted to combat this loss from a public perspective, little has been done to encourage private landowners to maintain and protect their coastal lands. This paper investigates the factors that influence private landowners to invest in coastal wetland restoration and maintenance activities in Louisiana. We surveyed private coastal landowners to determine their general socioeconomic characteristics, attitudes toward risks, attitudes toward wetland conservation, current uses of landholdings, and previous investments in wetland restoration and maintenance projects. Using this survey data, an... |

| In 1991, mandatory warning labels were imposed on the sale of oysters harvested from the Gulf of Mexico. Using an IAIDS model, this paper investigates the impact of these labels on the demand for Gulf product as well related oyster products (the Chesapeake, the Pacific, and imports). |

| In response to nutria-linked degradation of much of its coastal wetlands, Louisiana established the Coastwide Nutria Control Program (CNCP) in January 2002. CNCP instituted, among other things, an ‘‘economic incentive payment’’ of $4.00 per delivered nutria tail from registered participants in the program. To examine whether this bounty has had an impact on nutria harvest and whether alternative bounty levels can, in general, generate additional harvesting activities, we developed a bioeconomic supply model that relates Louisiana’s annual nutria harvests to a suite of economic and environmental factors. Results suggested that the annual nutria harvest is responsive to both the price received per animal and costs. Results also suggested that the nutria... |

| This report summarizes a year-long study of the current and future role of technology in the Mid-South, Southeast, and High Plains cotton production systems. Specific research objectives were to: 1) Identify the impacts of emerging technology on regional cotton production systems, including the implications of technology adoption on the economic and environmental stability of the system; 2) Examine the future direction of technical change in cotton production and its implications for the biological and economic structure of the cotton production system; and 3) Determine the potential role of future technologies on shifting regional competitiveness in cotton production. Information used in the analysis was collected through a series of consultations with... |

| This manuscript summarizes a total of 8 peer-reviewed studies, published from 1975 to 2001, reporting 24 separate estimates for the disaggregate2 value of habitat and species protection services provided by coastal and non-coastal wetlands. Estimates varied within a single order of magnitude and were fairly tightly bounded. Considering only coastal zone wetlands across all study categories, the value of habitat and species protection ranged from $168.96/acre/year to $403.16/acre/year, with a mean and median of $249.44/acre/year and $253.47/acre/year, respectively. By comparison, reported estimates of willingness-to-pay (WTP) values for wetland habitat and species protection services ranged from a low of $30.12 to $434.67, with a mean and median of $211.59... |

| A multinomial logit model was estimated and used to analyze the impact of various producer characteristics on the adoption of flow-through and recirculating technology in soft-shelled crab production. Because of the industry's geographic isolation and high turnover rate, data was collected by personal interviews in 1991. The results suggest that increased adoption might be fostered by targeting education programs towards full time, family operated businesses in nontraditional production regions. However, development of effective education programs may be hindered by the lack of a significant relationship between producer adoption decisions and the information provided by university or extension personnel. |

| This paper is the first in a planned series that seeks to synthesize and describe many of the economic questions that arise when attempting to develop groundwater and surface water management policy in Louisiana. In this series, current economic perspectives on water policy will be drawn from the technical and policy literature, with particular emphasis placed on the challenge of coordinating tradeoffs among different water users. While these reports will not attempt an exhaustive review of the broad water management literature, a comprehensive discussion of economic-based water management is a primary goal. In addition, the series will try to avoid focusing on a specific policy approach, but instead detail the issues and policy options that are often... |

| Developments in communication technology have created new opportunities in higher education, but they have also created new challenges. As the focus shifts from providing quality teaching to providing quality learning environments, faculty and administrators need to acquire a better understanding of student perceptions of these new technologies in order to intelligently plan academic programs. This research summarizes student perceptions of electronic delivery methods in selected agricultural economics courses at Louisiana State University during the 2002-03 and 2004-05 academic years. Preliminary results suggest that the "traditional" chalkboard classroom is rapidly disappearing across all curriculums and that students favor this change even though... |

| This manuscript summarizes a total of 12 peer-reviewed studies, published from 1981 to 2001, reporting 28 separate estimates for the disaggregate2 value of water quality services provided by coastal and non-coastal wetlands. Estimates ranged across three orders of magnitude and are highly dependent on the specific geographic site providing the service, the type of water quality service provided, the measurement technique, and whether locally derived benefits were calculated to extend across all existing wetlands. Considering only coastal zone wetlands across all study categories, the value of water quality services ranged from $2.85/acre/year to $5,673.80/acre/year, with a mean and median of $825.04/acre/year and $210.93/acre/year, respectively.

| A USGS analysis of land change data from satellite imagery and field observation indicated that 217 square miles of Louisiana's coastal wetlands were converted to open water because of Hurricanes Katrina and Rita. Because of their physical location and marine-dependence, commercial and recreational fishing sectors in Louisiana received a disproportional economic impact from the hurricanes of 2005. Storm surge modeling was accomplished using the ADCIRC model with data generated by the National Weather Service on storm trajectory and storm magnitude and detailed data on coastal bathymetry and elevation. In our application of the ADCIRC model, a grid composed of 1 square-mile cells (and encompassing the entire coastal management zone) was used within a GIS... |

| Octopus exports are an important source of foreign exchange for Mauritania. The export market has historically been dominated by coordinated Japanese buyers, a situation that led Mauritania to create the Societe Mauritanienne de Commercialisation de Poisson (SMCP) to negotiate with buyers and manage all octopus exports. Issues concerning competitiveness, price discrimination, and exchange rate pass-through in the Mauritanian octopus export market corrected for contemporaneous and serial correlation. Results indicate some degree of price discrimination across destination markets, market share enhancement through local currency price stabilization, and increases in marginal costs of production following nationalization of the Mauritanian trawler fleet. Thus,... |
