Bioeconomic modeling of wetlands and waterfowl in Western Canada: Accounting for amenity values AgEcon
van Kooten, G. Cornelis; Withey, Patrick; Wong, Linda.
This study extends an original bioeconomic model of optimal duck harvest and wetland retention by bringing in amenity values related to the nonmarket (in situ) benefits of waterfowl plsi the ecosystem values of wetlands themselves. The model maximizes benefits to hunters as well as the amenity values of ducks and ecosystem benefits of wetlands, subject to the population dynamics. Results indicate that wetlands and duck harvests need to be increased relative to historical levels. Further, the socially optimal ratio of duck harvest to wetlands is larger than what has been observed historically. Including amenity values leads to a significant increase in the quantity of wetlands and duck harvests relative to models that focus only on hunting values.

PUBLIC SUPPORT FOR LAND PRESERVATION: MEASURING RELATIVE PREFERENCES IN DELAWARE AgEcon
Duke, Joshua M.; Ilvento, Thomas W.; Hyde, Rhonda A..
Public preferences for nonmarket services of preserved land in Delaware are measured using two survey techniques. The results of a conjoint experiment, using a sample of 199 Delawareans, suggest that the environmental and agricultural attributes of preserved land are most important to the residents. The conjoint results also suggest that these services are of substantial value to Delawareans; at the margin, at least, agricultural and environmental preserved land provide net benefits to the public. The analytic hierarchy process is used to assess separate survey results from 129 Delawareans. The results provide specific weights on the relative importance of attributes and qualities of preserved land, which in large part replicate and reinforce the results...
