An Endogenously-Switching Ordered-Response Model of Information, Eligiblity and Participation in SSI
构建并估计了一个模型，将SSI参与、信息与对项目资格的认知结合起来，发现信息获取与参与本身一样对项目慷慨程度敏感，错误信息可能是低参与率的近因，部分源于低感知净收益。
A model incorporating SSI participation, information and perceptions of program eligibility is developed and estimated using data from the 1980 PSID. The model assumes the participation decision process begins in an uninformed regime and switches to an informed regime if the perceived benefits are sufficiently high. In this informed regime individuals participate if perceived benefits exceed perceived costs. We find that the acquisition of information is responsive to actual program generosity just as is participation itself. Faulty information, which may be the proximate cause of low participation rates, is apparently, in part, a consequence of low perceived net benefits. Copyright 1990 by MIT Press.
