| 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). |

| Based on 1990-2004 quarterly data, U.S. and E.U. demand for imported shrimp by alternative supply sources was examined within an Almost Ideal Demand System framework. For the United States, supply sources included Central America, South America, and Asia. Supply sources for the European Union included Asia, South America, and Rest of World. All own-price elasticities for the U.S. system were found to be elastic while all own-price elasticities associated with the E.U. system were found to be inelastic. With few notable exceptions, estimated cross-price elasticities suggest substitution among import sources. Finally, shrimp of Asian origin were found to be highly expenditure elastic in the US market while shrimp of South American origin were found to be the... |

| 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... |

| 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 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... |
