The Journal of Economic Literature codes classification system (JEL) published by the American Association (AEA) is de facto standard for research literature in economics. JEL used to classify articles, dissertations, books, book reviews, and working papers EconLit, a database maintained AEA. Over time, it has evolved extended with over 850 subclasses. This paper reviews history development sys...

We study whether and how peer referrals increase screening, testing, identification of patients with tuberculosis, an infectious disease responsible for over one million deaths annually. In experiment 3,176 at 122 tuberculosis treatment centers in India, we find that small financial incentives raise the probability existing refer prospective screening resulting cost-effective new cases. Incenti...

Housing is mostly exempted from Medicaid and Supplemental Social Insurance means tests. Reforms of this special treatment have been debated, but little known about its costs, benefits, redistributive implications. I estimate a life cycle model single retirees accounting for exemption. It shows that the homestead exemption explains important patterns recipiency it highly valued. also estate reco...

We study the drivers of geographic variation in US health care utilization, using an empirical strategy that exploits migration of Medicare patients to separate the role of demand and supply factors. Our approach allows us to account for demand differences driven by both observable and unobservable patient characteristics. Within our sample of over-65 Medicare beneficiaries, we find that 40-50 ...

We study targeted lockdowns in a multigroup SIR model where infection, hospitalization, and fatality rates vary between groups—in particular the “young,” “middle-aged,” “old.” Our enables tractable quantitative analysis of optimal policy. For baseline parameter values for COVID-19 pandemic applied to US, we find that policies differentially targeting risk/age groups significantly outperform uni...

We study optimal dynamic lockdowns against COVID-19 within a commuting network. Our framework integrates canonical spatial epidemiology and trade models is applied to cities with varying initial viral spread: Seoul, Daegu, the New York City metropolitan area (NYM). Spatial achieve substantially smaller income losses than uniform lockdowns. In NYM Daegu—with large shocks—the lockdown restricts i...

Participants in means-tested programs must periodically document eligibility through a recertification process. If all cases that fail are ineligible, the exact timing of this process should be irrelevant. We find later interview assignments for Supplemental Nutrition Assistance Program (SNAP), which leave less time to reschedule missed interviews, decrease success by 22 percent. The consequenc...

Combining administrative data from the US Army, Department of Veterans Affairs, and Social Security Administration, we analyze the effect of the VA’s Disability Compensation (DC) program on veterans’ labor force participation and earnings. We study the 2001 Agent Orange decision, a unique policy change that expanded DC eligibility for Vietnam veterans who served in theater but did not expand el...

We study the drivers of geographic variation in U.S. health care utilization, using an empirical strategy that exploits migration of Medicare patients to separate the role of demand and supply factors. Our approach allows us to account for demand differences driven by both observable and unobservable patient characteristics. Within our sample of over-65 Medicare beneficiaries, we find that 40–5...

Using data covering over 100 birth-cohorts in 32 countries, we examine the shortand long-term effects of economic conditions on mortality. We find that small, but not large, booms increase contemporary mortality. Yet booms from birth to age 25, particularly those during adolescence, lower adult mortality. A simple model can rationalize these findings if economic conditions differentially affect...
