A DOUBLE HURDLE APPROACH TO EVALUATING NON-RESIDENTIAL WILDLIFE WATCHING IN THE UNITED STATES AgEcon
Diagne, Assane; Lavergne, David R.; Olatubi, Williams O..
In 1996, over 62 million U.S. residents participated in wildlife watching and spent in excess of 29 billion dollars in this recreational activity. Wildlife watching can be defined as the observation, study, and enjoyment of natural areas and its wild fauna and flora. Residential wildlife watching takes place within one mile of the participant's residence and is often an incidental or secondary activity. Non-residential wildlife watching refers to recreation taking place at a distance of at least one mile from the participant's residence. In recent years, a sharp decline in the number of wildlife watchers has been noted. Between 1991 and 1996, the number of wildlife watchers decreased by 17 percent. During this time interval, the largest decline in...

IRRIGATION AND POTENTIAL DIVERSIFICATION BENEFITS IN HUMID CLIMATES AgEcon
Vandeveer, Lonnie R.; Paxton, Kenneth W.; Lavergne, David R..
Income variability and means for managing risk continue to receive much attention in farm management research. In this paper, irrigation is presented as a risk-management strategy that offers potential diversification benefits. Potential diversification opportunities largely result from a wider range of enterprise production activities. A portfolio analysis of dryland and irrigated farm scenarios indicates that income stabilizing and diversification effects of irrigation substantially modify the risk-return position of a typical farm in northeast Louisiana. Safety-first considerations along with Target MOTAD programming procedures also are used to evaluate the impact of irrigation on the farm's financial performance.

ASSESSING THE LOUISIANA SHRIMP FISHING FLEET TECHNICAL EFFICIENCY USING A BAYESIAN STOCHASTIC COST FRONTIER MODEL AgEcon
Icabalceta, Jorge L.; Lavergne, David R..
A Bayesian stochastic cost frontier analyzed the shrimp fleet of Louisiana. A translog cost function was estimated. 269 vessels were included and sub-grouped by length (<20 ft, 21-40ft, and >60ft), and net type (trawl, skimmer, and butterfly). Results indicated no influence of these factors on cost efficiency.
