演講摘要 : Researchers using stated preference methods typically hold one of two beliefs about the preference information they obtain: respondents always answer questions truthfully or they answer truthfully only when it is in their interest to do so. The second position is consistent with economic theory, but it implies that the interpretation of survey responses depends critically on the incentive structure provided and the success in conveying that incentive structure. We derive the simplest tests capable of distinguishing between the two views in the context of a vote on a public good. The key test has similarities to the commonly used random lottery approach used in experimental economics but requires a weaker assumption than expected utility which we term mixture monotonicity. The empirical part of the paper uses a binary discrete choice on whether a unique baseball memorabilia item should be provided to all or no members of a group at a specified fixed individual price. The tests are cast in terms of the probability of influencing the outcome and the success in creating a true take- it-or-leave- it offer. Empirical results are consistent with the predictions from the neoclassical theoretical model.
