Modeling response incentive effects in dichotomous choice contingent valuation data

This paper introduces model specifications that can be used to explain response incentive effects that might occur with discrete response contingent valuation data when follow-up responses are collected. The models allow for possible random response shocks, structural shifts in willingness to pay between payment questions and heteroskedasticity between and within responses. Three well-known contingent valuation survey datasets that include follow-up payment questions are used to empirically test the models.
