摘要：The focus of this investigation is three-fold. First, seminonparametric techniques are considered in order to avoid the pitfall of imparting bias on value estimates. Second, the efficacy of seminonparametric techniques are explored in an empirical setting by valuing recreational access at Clear Lake, Iowa. Finally, a technique from Eastwood and Gallant (1991) is adapted and applied to the count data model.
