摘要：The economic values of investing in long-term public projects are highly sensitive to the social discount rate (SDR). We surveyed over 200 experts to disentangle disagreement on the risk-free SDR into its component parts, including pure time preference, the wealth effect, and return to capital. We show that the majority of experts do not follow the simple Ramsey Rule, a widely used theoretical discounting framework, when recommending SDRs. Despite disagreement on discounting procedures and poi...

摘要：One-in-seven Americans received benefits from the Supplemental Nutrition Assistance Program in 2011, an all-time high. We analyze changes in program enrollment over the past two decades, quantifying the contributions of unemployment and state policy changes. Using instrumental variables to address measurement error, we estimate that a 1 percentage point increase in unemployment raises enrollment by 15 percent. Unemployment explains most of the decrease in enrollment in the late 1990s, state po...

摘要：For individuals who experience job loss, enrollment in postsecondary programs may provide an opportunity to improve future employment outcomes. However, decisions to enroll may be hampered by insufficient information about the benefits and costs and the necessary steps and assistance available to facilitate such investments. Using variation in the dissemination and timing of letters sent to Unemployment Insurance (UI) recipients containing this information, we find that individuals sent the in...

摘要：Climate change remains one of the major international environmental challenges facing nations. Up to now, nations have adopted minimal policies to slow climate change. Moreover, there has been no major improvement in emissions trends as of the latest data. The current study uses the updated DICE model to develop new projections of trends and impacts of alternative climate policies. It also presents a new set of estimates of the uncertainties about future climate change and compares the results...

摘要：Texas is the only US state that limits home equity borrowing to 80 percent of home value. This paper exploits this policy discontinuity around Texas' interstate borders and uses a multidimensional regression discontinuity design framework to find that limits on home equity borrowing in Texas lowered the likelihood of mortgage default by about 1.5 percentage points for all mortgages and 4-5 percentage points for non-prime mortgages. Estimated non-prime mortgage default hazards within 25 to 100 ...

摘要：It is found that electorally induced policy uncertainty decreases manufacturing investment in US states. In a state with average partisan polarization, the elasticity of election-year investment to a specific measure of policy uncertainty is -0.027. When the incumbent governor is term limited, there is greater uncertainty over the outcome, providing an instrument to demonstrate this effect is causal, not simply coincidental. Moreover, manufacturing investment does not rebound following the ele...

摘要：Medicaid programs increasingly finance competing, capitated managed care plans rather than administering fee-for-service (FFS) programs. We study how the transition from FFS to managed care affects high- and low-cost infants (blacks and Hispanics, respectively). We find that black-Hispanic disparities widen-e.g., black mortality and preterm birth rates increase by 15 percent and 7 percent, respectively, while Hispanic mortality and preterm birth rates decrease by 22 percent and 7 percent, resp...

摘要：Since 2007, US coal-fired electricity ation has declined by a stunning 25 percent. Detailed daily unit-level data is used to examine the joint impact of natural gas prices and wind generation on coal-fired generation and emissions, with a focus on the interaction between gas prices and wind. This interaction is found to he significant. Marginal responses of coal-fired generation to natural gas prices (wind) in 2013 were larger, sometimes much. larger, than the counterfactual with 2008 wind gen...

摘要：We use individual level data on purchases of cholesterol-lowering drugs to study the responses of physicians and patients to variation in the cost of drugs. In a sample of first-time statin prescriptions to employees from 12 Fortune 500 firms, we find that co-pay variation across plans has a small effect on the choice of drug, and this effect does not vary with patient income. After the highly publicized patent expiration of Zocor, however, prescriptions for this drug increased substantially, ...

摘要：Firms and governments often use moral suasion and economic incentives to influence intrinsic and extrinsic motivations for economic activities. To investigate persistence of such interventions, we randomly assign households to moral suasion and dynamic pricing that stimulate energy conservation during peak-demand hours. We find significant habituation and dishabituation for moral suasion-the treatment effect diminishes after repeated interventions but can be restored to the original level by a...
