Going Off Parole: How the Elimination of Discretionary Prison Release Affects the Social Cost of Crime

In order to lengthen prison terms, many U.S. states have limited parole boards' traditional authority to grant early releases. I develop a framework in which the welfare effects of this reform depend on (1) the elasticity of future recidivism with respect to time in prison, (2) the accuracy of boards in conditioning release dates on recidivism risk, and (3) the extent to which such conditioning encourages inmates to reform. Using micro-data from Georgia and quasi-experimental variation arising from policy shocks and institutional features of its criminal justice system, I find that longer prison terms decrease recidivism, boards assign higher-risk inmates to longer terms, and inmates' investment in rehabilitative activities falls -- and their recidivism rises -- when boards' discretion is limited. Back-of-the-envelope calculations suggest that the benefits of parole (the ability to ration prison resources based on recidivism risk and the creation of incentives) outweigh the costs (lost incapacitation due to shorter prison terms).

Human Capital Spillovers in Families: Do Parents Learn from or Lean on their Children?

I develop a model in which a child's acquisition of a given form of human capital incentivizes adults in his household to either learn from him (if children act as teachers then adults' cost of learning the skill falls) or lean on him (if children's human capital substitutes for that of adults in household production then adults' benefit of learning the skill falls). I exploit regional variation in two shocks to children's human capital and examine the effect on adults. The rapid introduction of primary education for black children in the South during Reconstruction not only increased literacy of children but also of adults living in the same household ("learning" outweighs "leaning"). Conversely, the 1998 introduction of English immersion in California public schools appears to have increased the English skills of children but discouraged adults living with them from acquiring the language ("leaning" outweighs "learning"). Whether family members learn from or lean on each other has implications for the externalities associated with education policies.

An Empirical Analysis of Imprisoning Drug Offenders

The number of prisoners incarcerated on drug-related offenses rose fifteen-fold between 1980 and 2000. This paper provides the first systematic empirical analysis of the implications of that dramatic shift in public policy. We show that the increase in drug prisoners led to reductions in expected time served for other crimes, especially for less serious offenses. Reductions in time served, however, increased other crimes by no more than a few percent. Moreover, incarcerating drug offenders is found to be almost as effective in reducing violent and property crime as locking up other types of offenders. We estimate that cocaine prices are 10-15 percent higher today as a consequence of increases in drug punishment since 1985. Based on previous estimates of the price elasticity of demand for cocaine, this implies a reduction in cocaine consumed of as much as 20 percent.

The Demand for Health Insurance among Uninsured Americans: Results of a Survey Experiment and Implications for Policy

Most existing work on the price elasticity of demand for health insurance focuses on employees' decisions to enroll in employer-provided plans. Yet any attempt to achieve universal coverage must focus on the uninsured, the vast majority of whom are not offered employer-sponsored insurance. In the summer of 2008, we conducted a survey experiment to assess the willingness to pay for a health plan among a large sample of uninsured Americans. The experiment yields price elasticities substantially greater than those found in most previous studies. We use these results to estimate coverage expansion under the Affordable Care Act, with and without an individual mandate. We estimate that 39 million uninsured individuals would gain coverage and find limited evidence of adverse selection.health insurance, universal coverage, Affordable Care Act, price elasticity of demand

Robin Hood and His Not-So-Merry Plan: Capitalization and the Self-Destruction of Texas' School Finance Equalization Plan

School finance schemes control the allocation of $370 billion a year in the United States, but their economics are poorly understood. We examine an illuminating example: Texas' Robin Hood' scheme, which was enacted in 1994, allocates about$30 billion a year, and is currently collapsing and likely to be abandoned. We show that the collapse was predictable. Robin Hood's design causes substantial negative capitalization, shrinking its own tax base. It relies only slightly on relatively efficient (pseudo lump sum) redistibution and heavily on high marginal tax rates. Although Robin Hood reduced the spending gap between Texas' property-poor and property-rich districts by $500 per pupil, it destroyed about$27,000 per pupil in property wealth. The magnitude of this loss is important: if the state had efficiently confiscated the same wealth and invested it, it would generate sufficient annual income to make all Texas schools spend at a high leval. The Robin Hood scheme is stringent but not bizarre: other states' systdms share its features to some degree. We provide estimates of the effects of school finance system parameters, which policy makers could use to design systems that are more efficient and stable.

The Homecoming of American College Women: The Reversal of the College Gender Gap

Women are currently the majority of U.S. college students and of those receiving a bachelor%u2019s degree, but were 39 percent of undergraduates in 1960. We use three longitudinal data sets of high school graduates in 1957, 1972, and 1992 to understand the narrowing of the gender gap in college and its reversal. From 1972 to 1992 high school girls narrowed the gap with boys in math and science course taking and in achievement test scores. These variables, which we term the proximate determinants, can account for 30 to 60 percent of the relative increase in women%u2019s college completion rate. Behind these changes were several others: the future work expectations of young women increased greatly between 1968 and 1979 and the age at first marriage for college graduate women rose by 2.5 years in the 1970s, allowing them to be more serious students. The reversal of the college gender gap, rather than just its elimination, was due in part to the persistence of behavioral and developmental differences between males and females.

How does Risk-selection Respond to Risk-adjustment? Evidence from the Medicare Advantage Program

Medicare administers a traditional public fee-for-service (FFS) plan while also allowing enrolles to join government-funded private Medicare Advantage (MA) plans.We model how selection and differential payments - the value of the capitation payments the firm receives to insure an individual minus the counterfactual cost of his coverage in FFS - change after the introduction of a comprehensive risk adjustment formula in 2004. Our model predicts that firm screening efforts along dimensions included in the model ("extensive-margin" selection) should fall, whereas screening efforts along dimensions excluded ("intensive-margin" selection) should increase. These endogenous responses to the risk-adjustment formula can in fact lead differential payments to increase. Using individual-level administrative data on Medicare enrollees from 1994 to 2006, we show that while MA enrollees are positively selected throughout the sample period, after risk adjustment extensive-margin selection decreases whereas intensive-margin selection increases. We find that differential payments actually rise after risk-adjustment, and estimate that they totaled $23 billion in 2006, or about six percent of total Medicare spending.Health Care Markets

How does Risk Selection Respond to Risk Adjustment? Evidence from the Medicare Advantage Program

Governments often contract with private firms to provide public services such as health care and education. To decrease firms' incentives to selectively enroll low-cost individuals, governments frequently "risk-adjust" payments to firms based on enrollees' characteristics. We model how risk adjustment affects selection and differential payments---the government's payments to a firm for covering an individual minus the counterfactual cost had the government directly covered her. We show that firms reduce selection along dimensions included in the risk-adjustment formula, while increasing selection along excluded dimensions. These responses can actually increase differential payments relative to pre-risk-adjustment levels and thus risk adjustment can raise the total cost to the government of providing the public service. We confirm both selection predictions using individual-level data from Medicare, which in 2004 began risk-adjusting payments to private Medicare Advantage plans. We find that differential payments actually rise after risk adjustment and estimate that they totaled $30 billion in 2006, or nearly eight percent of total Medicare spending.

'Last-place Aversion': Evidence and Redistributive Implications

We present evidence from laboratory experiments showing that individuals are "last-place averse." Participants choose gambles with the potential to move them out of last place that they reject when randomly placed in other parts of the distribution. In modified-dictator games, participants randomly placed in second-to-last place are the most likely to give money to the person one rank above them instead of the person one rank below. Last-place aversion suggests that low-income individuals might oppose redistribution because it could differentially help the group just beneath them. Using survey data, we show that individuals making just above the minimum wage are the most likely to oppose its increase. Similarly, in the General Social Survey, those above poverty but below median income support redistribution significantly less than their background characteristics would predict
