This paper empirically implements an averting behavior model for gypsy
moth control explicitly recognizing the joint private and public spil
lover motivations for control. The results demonstrate that averting b
ehavior models can capture complex behavioral influences, suggesting t
hat such models can be extended beyond health-related applications. Th
e model yields a reduced form parameter which cannot be identified usi
ng actual behavior data alone. A method combining models of actual beh
avior and contingent behavior is proposed as a way to directly measure
the production and preference effects.
