AN ECONOMIC, HYDROLOGIC, AND ENVIRONMENTAL ASSESSMENT OF WATER MANAGEMENT ALTERNATIVE PLANS FOR THE SOUTH CENTRAL TEXAS REGION AgEcon
Gillig, Dhazn; McCarl, Bruce A.; Boadu, Frederick O..
Regional water scarcity has motivated the South Central Texas Regional Water Planning Group to actively develop water management plans to address long-/short-term regional water needs. This study, therefore, develops an integrated Edwards Aquifer groundwater and river system simulation model to determine the "best" choice of regional water management plans using mixed-integer linear programming. The economic, hydrologic, and environmental consequences of the "best" choice of regional and other water management plans and options are evaluated and compared. Results indicate a tradeoff between the economic and environmental benefits. A slight decrease in economic benefit results in a substantial increase in environmental benefit.

Joint Estimation of Revealed and Stated Preference Data: An Application to Recreational Red Snapper Valuation AgEcon
Gillig, Dhazn; Woodward, Richard T.; Ozuna, Teofilo, Jr.; Griffin, Wade L..
This study extends the joint estimation of revealed and stated preference data literature by accounting for truncation in the revealed preference data. The analytical model and estimation procedure are used to estimate the value of recreational red snapper fishing in the Gulf of Mexico. This recreational red snapper valuation is decomposed into its direct and indirect components. As expected, the value of recreational red snapper fishing using the joint revealed-stated preference model proposed in this analysis is bracketed on the upper limit by the value obtained using the contingent valuation method and on the lower limit by the travel cost method. The results also indicate that the joint model improves the precision of estimated recreational red snapper...
