Observable preferences for public goods: A note on the incentive compatibility of inferring demand for public goods from private goods demand
Bradford和Hildebrandt提出可从互补私人物品需求推断公共品偏好，并认为该方法能避免消费者谎报偏好，但本文证明一般情况下并非如此。
Bradford and Hildebrandt show that under certain conditions preferences for public goods can be inferred from the demand for complementary private goods. They conjecture that their method overcomes consumers' incentives to misrepresent their public goods preferences, but this paper shows that in general this is not the case.
