Buyback Programs for Capacity Reduction in the U.S. Atlantic Shark Fishery AgEcon
Larkin, Sherry L.; Keithly, Walter R., Jr.; Adams, Charles M.; Kazmierczak, Richard F., Jr..
Declining fishery stocks, increasing fishing effort and adverse market conditions have produced difficult financial situations for fishermen worldwide. Several high-valued fisheries are considered to be overcapitalized. The purchase and permanent retirement of fishing vessels and/or permits under a buyback program is one approach for reducing fishing capacity. Evidence from previous programs, however, suggests that buybacks are not a panacea for solving overcapacity problems. Whether such programs can help rebuild stocks and improve the financial condition of fleets in any specific fishery depends on a multitude of factors. We consider the potential of a buyback program for the U.S. Atlantic shark fishery.

Dynamics of Heterogeneous Congestion Tolerance in the Location Choices of U.S. Gulf of Mexico Shrimp Fishermen AgEcon
Ran, Tao; Keithly, Walter R., Jr.; Kazmierczak, Richard F., Jr..
Location choice is one of the most important short-run decisions made by commercial fishermen. Previous studies of location choice by commercial fishermen have focused primarily on site fidelity, profit-maximization behavior, and risk attitudes as factors influencing their location choice behavior. Although the recreational literature gives extensive consideration to the influence of congestion on site selection, few studies have considered the influence of congestion tolerance on site selection in the commercial fishing sector. This study uses a mixed logit model to analyze the heterogeneous congestion tolerance in location choice among U.S. Gulf of Mexico shrimp fishermen. The dynamics of fishermen responses to economic conditions are compared and...

Economic And Physical Measures of Efficiency: the Case of the Gulf of Mexico Grouper Fishery AgEcon
Diop, Hamady; Keithly, Walter R., Jr.; Kazmierczak, Richard F., Jr.; Diagne, Assane.
Results indicate that both long- and vertical liners experience random shocks as well as inefficiency. The longliners vessel efficiency is increasing over time and crew size and effort are positively correlated with efficiency. The vertical liners efficiencies are also positively associated with crew size as the vessels become specialized in grouper targeting.

ECONOMIC LINKAGES BETWEEN COASTAL WETLANDS AND HABITAT/SPECIES PROTECTION: A REVIEW OF VALUE ESTIMATES REPORTED IN THE PUBLISHED LITERATURE AgEcon
Kazmierczak, Richard F., Jr..
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...

ECONOMIC LINKAGES BETWEEN COASTAL WETLANDS AND HUNTING AND FISHING: A REVIEW OF VALUE ESTIMATES REPORTED IN THE PUBLISHED LITERATURE AgEcon
Kazmierczak, Richard F., Jr..
This manuscript summarizes a total of 12 peer-reviewed studies, published from 1978 to 2001, reporting 32 separate estimates for the disaggregate2 value of hunting and fishing 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 target species of the hunting and fishing activity, and the measurement technique. Considering only coastal zone wetlands across all study categories, the value of wetlands to single-target hunting and fishing (oysters, menhaden, etc.) ranged from $1.05/acre/year to $663.74/acre/year, with a mean and median of $113.95/acre/year and $10.03/acre/year, respectively. Considering only coastal zone...

ECONOMIC LINKAGES BETWEEN COASTAL WETLANDS AND WATER QUALITY: A REVIEW OF VALUE ESTIMATES REPORTED IN THE PUBLISHED LITERATURE AgEcon
Kazmierczak, Richard F., Jr..
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.

ECONOMIC MANAGEMENT OF FRESHWATER RESOURCES I: THE ECONOMIC CHARACTERISTICS OF WATER AgEcon
Kazmierczak, Richard F., Jr..
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...

Electronic Course Delivery: Do Students Care and Do They Think It's Worthwhile? AgEcon
Henning, Steven A.; Vandeveer, Lonnie R.; Kazmierczak, Richard F., Jr..
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...

Estimating the Economic Damage of Hurricanes Katrina and Rita on Commercial and Recreational Fishing Industries AgEcon
Caffey, Rex H.; Kazmierczak, Richard F., Jr.; Diop, Hamady; Keithly, Walter R., Jr..
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...

Estimating the Supply Curve for Nutria Pelts From Coastal Louisiana and the Impacts Associated with Declining Prices AgEcon
Dedah, Cheikhna O.; Isaacs, Jack C.; Keithly, Walter R., Jr.; Kazmierczak, Richard F., Jr..
Nutria harvests vary with price. As pelt prices declined, nutria populations - and wetland degradation – have risen. This paper develops a nutria supply model to predict harvests at various prices which are incorporated into a wetland loss model to determine how alternative incentive programs affect changes in wetland degradation.

Factors Influencing Private Landowner Restoration Investment Decisions in Coastal Louisiana AgEcon
Dedah, Cheikhna O.; Kazmierczak, Richard F., Jr.; Keithly, Walter R., Jr..
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...

FACTORS INFLUENCING TECHNOLOGY ADOPTION IN A LOUISIANA AQUACULTURE SYSTEM AgEcon
Caffey, Rex H.; Kazmierczak, Richard F., Jr..
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.

Location Choice Behavior of Gulf of Mexico Shrimpers under Dynamic Economic Conditions AgEcon
Ran, Tao; Keithly, Walter R., Jr.; Kazmierczak, Richard F., Jr..
This study uses a mixed logit model to analyze monetary and nonmonetary factors that influence location choice behavior of the U.S. Gulf of Mexico shrimpers. Shrimpers’ responses to economic conditions are compared and contrasted for two periods related to changing economic conditions in the industry. Results show that even though shrimpers are generally revenue driven in choosing a fishing site, their past experience also plays an important role. Further, changes in economic conditions appear to exhibit an influence on the risk attitudes of some shrimpers.

Noncompetitive Pricing and Exchange Rate Pass-Through in Mauritanian Octopus Export Markets AgEcon
Kazmierczak, Richard F., Jr.; Zapata, Hector O.; Diop, Hamady.
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,...

OPTIMIZING COMPLEX BIOECONOMIC SIMULATIONS USING AN EFFICIENT SEARCH HEURISTIC AgEcon
Kazmierczak, Richard F., Jr..
For simulation to be truly useful for investigating many problems in agricultural economics, non-simplifying optimization techniques need to be employed. General methods for simulation optimization that do not inhibit system characterization or analysis are available, and they would appear to provide much of the mathematical and optimizing rigor demanded by economists. This paper describes the theory and algorithm of a robust and efficient simulation optimization approach, the Complex Method. An example of implementing the algorithm is illustrated using a pest management problem.

REASONABLE VALUE AND THE ROLE OF NEGOTIATION IN AGRICULTURE'S USE OF THE ENVIRONMENT AgEcon
Kazmierczak, Richard F., Jr.; Hughes, David W..
Social pressures to regulate agriculture's use of environmental resources have been building for many years and show no signs of abating. While the agricultural and environmental communities can react to these events in many ways, perhaps the most promising avenue for resolving joint agricultural and environmental disputes lies with negotiated regulations mediated by governmental agencies. When first conceived by Commons, negotiated regulation was seen as a way to achieve both efficient and equitable dispute resolution by directly using the preferences, skills, and operational knowledge of stakeholders. This approach should be attractive to the agricultural community because it provides an opportunity to educate environmental groups about the...

TECHNOLOGY AND MANAGEMENT IN MAURITANIAN CEPHALOPOD FISHERIES AgEcon
Diop, Hamady; Kazmierczak, Richard F., Jr..
If the technology in a multi-species fishery is such that there is jointness in inputs and non-separability between inputs and outputs, then management on a species-by-species basis may lead to unintended outcomes, including over-exploitation of the resource. This study investigates the nature of the technical and economic relationships underlying the 1989-1990 Mauritanian cephalopod fishery by estimating a system of dual output supply functions derived from a generalized Leontief revenue function. Model results indicate the existence of jointness in inputs and non-separability between inputs and outputs in the fishery. Cross-price elasticities indicated a number of substitute and complementary relationships, with these relationships changing in...
