摘要：A hyperbolic discounting model of labour supply and welfare participation with heterogeneous time preference parameters is estimated. Exclusion restrictions are constructed from variations in behaviour induced by time limits in a welfare reform experiment. We find that most individuals are time-inconsistent, and they exhibit varying degrees of present bias and perception of the commitment problem. Introducing a welfare component to the tax system can make individuals worse off by aggravating t...

摘要：Many health care treatments are not urgent and may be delayed if patients so choose. Because insurance coverage is typically determined by the treatment date, individuals may have incentives to strategically delay treatments to minimize out-of-pocket costs. The strategic delay of treatment-a particular form of moral hazard-can be an important source of subsequent adverse selection, in which ex ante identical individuals select insurance coverage based on their differing accumulation of previou...

摘要：We study the manipulability of stable matching mechanisms. To quantify incentives to manipulate stable mechanisms, we consider markets with random cardinal utilities, which induce ordinal preferences over match partners. We show that most agents in large matching markets are close to being indifferent of overall stable matchings. In one-to-one matching, the utility gain by manipulating a stable mechanism does not exceed the gap between utilities from the best and worst stable partners. Thus, m...

摘要：This article studies multidimensional matching between workers and jobs. Workers differ in manual and cognitive skills and sort into jobs that demand different combinations of these two skills. To study this multidimensional sorting problem, I develop a theoretical framework that generalizes the unidimensional notion of assortative matching and sufficient conditions on the technology under which sorting obtains. I derive the equilibrium in closed form and use this explicit solution to study bi...

摘要：We explore subjective performance reviews in long-term employment relationships. We show that firms benefit from separating the task of evaluating the worker from the task of paying him. The separation allows the reviewer to better manage the review process, and can, therefore, reward the worker for his good performance with not only a good review contemporaneously, but also a promise of better review in the future. Such reviews spread the reward for the worker's good performance across time a...

摘要：All individuals face some risk of ending up old, sick, alone, and poor. Is there a role for social insurance for these risks and, if so, what is a good programme? A large literature has analysed the costs and benefits of pay-as-you-go public pensions and found that the costs exceed the benefits. This article, instead, considers means-tested social insurance (MTSI) programmes for retirees such as Medicaid and Supplemental Security Income. We find that the welfare gains from these programmes are...
