摘要：The use of a constant discount rate to study long-lived environmental problems such as global warming has two disadvantages: the prescribed policy is sensitive to the discount rate, and with moderate discount rates, large future damages have almost no effect on current decisions. Time-consistent quasi-hyperbolic discounting alleviates both of these modeling problems, and is a plausible description of how people think about the future. We analyze the time-consistent Markov Perfect equilibrium i...

摘要：One of the features of the large overlapping generations model pioneered by Auerbach and Kotlikoff (1987) Dynamic Fiscal Policy is that individuals with different experience levels are perfect substitutes in production. This paper replaces this assumption with a labor market characterized by imperfect substitutability between less and more experienced workers. By comparing the quantitative properties of both cases in a calibrated model for Spain, it is found that in the model economy with impe...

摘要：This paper estimates the equivalence scale revealed by discretionary community allocations of welfare benefits to poor households. I apply the proposed approach to a subsidized rice program in Indonesia in which villages designated program beneficiaries, and estimate the equivalence scale implicit in the beneficiaries they selected. I find that the revealed community equivalence scale for this program lies much closer to per capita expenditure than traditional demand-based equivalence scales, ...

摘要：Since the introduction of school vouchers in 1992, independent and public schools in Sweden operate on equal terms. We analyze the effects of competition on the public schools using data on the results of 28,000 ninth graders. Because the decision on which school to attend is a choice variable, sample selection models are used. To account for the potential endogeneity of the share of students attending independent schools, we use instrumental variable estimation. We also estimate panel data mo...

摘要：We examine the retirement behavior of federal civil service workers employed by the Department of Defense. These workers provide an interesting population for studying retirement because they face relatively simple financial incentives, high quality administrative data are available, and they are not covered by the Social Security system. We find that these workers respond to their financial incentives in a similar manner to what others have found when analyzing much different retirement syste...

摘要：Using data on the universe of students who graduated from US medical schools between 1996 and 1998, we examine whether the abilities and specialty preferences of a medical school class affect a student's academic achievement in medical school and his choice of specialty. We mitigate the selection problem by including school-specific fixed effects, and show that this method yields an upper bound on peer effects for our data. We estimate positive peer effects that disappear when school-specific ...

摘要：Willingness-to-pay for climate change mitigation depends on people's perceptions about just how bad things will get if nothing is done. Individual subjective distributions for future climate conditions are combined with stated choices over alternative climate policies to estimate individual option prices (the appropriate ex ante welfare measure in the face of uncertainty) for climate change mitigation. We find statistically significant sensitivity of estimated option prices to both expected fu...

摘要：The paper considers a two-community model with freely mobile individuals. Individuals differ not only in their incomes, but also in their tastes for a local public good. In each jurisdiction, the amount of public services is determined by majority vote of the inhabitants, and local spending is financed by a residence-based linear income tax. When making their residential and political choices, individuals thus face a trade-off between the provisionary and redistributive effects of policies. We...

摘要：A structural life cycle model of retirement and wealth attributes retirement peaks at both ages 62 and 65 to Social Security rules and wide heterogeneity in time preferences. Those with high discount rates often retire at 62. They have few assets and heavily value lost benefits from working after 62, largely ignoring potential increases in later benefits. Declining actuarial adjustments beginning at 65 induce those with low discount rates to retire at 65. Raising the Social Security early enti...

摘要：Quasi-hyperbolic discounting predicts impatience over short-run tradeoffs. I present a direct non-laboratory test of this implication using data on the nutritional intake of food stamp recipients. Caloric intake declines by 10 to 15 percent over the food stamp month, implying a significant preference for immediate consumption. These findings constitute a rejection of the permanent income hypothesis and are extremely difficult to reconcile with exponential discounting. The data support an expla...
