Natural Disasters and Acceptance of Domestic Violence
Natural disasters cause economic losses and are expected to become more frequent due to climate change. While economic consequences of natural disasters have been well-documented by research, their intangible effects have received less attention. This article studies the effect of natural disasters on attitudes toward domestic violence. The study estimates the impact of the 2006 Yogyakarta earthquake in Indonesia on acceptance of wife beating usi…
The Impact of Income-Related Medicare Part B Premiums on Labor Supply
The 2003 Medicare Modernization Act introduced income-related premiums on Medicare coverage for professional services (Part B) for the first time. Beginning in 2007, higher-income households were required to pay higher premiums for Part B coverage, which raises the price of Medicare relative to employer-sponsored health insurance for these households. The authors exploit this exogenous change in Medicare policy to examine the impact of Part B pre…
ACA Medicaid Expansion Associated With Increased Medicaid Participation and Improved Health Among Near-Elderly
The Affordable Care Act (ACA) dramatically expanded health insurance, but questions remain regarding its effects on health. We focus on older adults for whom health insurance has greater potential to improve health and well-being because of their greater health care needs relative to younger adults. We further focus on low-income adults who were the target of the Medicaid expansion. We believe our study provides the first evidence of the health-r…
Evidence of Racial and Geographic Disparities in the Use of Medicare Observation Stays and Subsequent Patient Outcomes Relative to Short-Stay Hospitalizations
PURPOSE: To examine racial and geographic disparities in the use of-and outcomes associated with-Medicare observation stays versus short-stay hospitalizations. METHODS: We used 2007-2010 fee-for-service Medicare claims, including 3,555,994 observation and short-stay hospitalizations for individuals over age 65. We estimated linear probability models with hospital fixed effects to identify within-facility disparities in observation stay use, and e…
Chest Pain Patients at Veterans Hospitals Are Increasingly More Likely to Be Observed Than Admitted for Short Stays
Observation stays are an outpatient service used to diagnose and treat patients for extended periods of time while a decision is made regarding inpatient admission or discharge. Although the use of observation stays is increasing, little is known about which patients are observed and which are admitted for similar periods of time as inpatients. The aim was to identify patient characteristics associated with being observed rather than admitted for…
Will Health Care Reform Reduce Disparities in Insurance Coverage
OBJECTIVES: We used data from the Medical Expenditure Panel Survey to assess the impact of the Affordable Care Act's dependent coverage mandate on disparities in health insurance coverage rates and evaluated whether non-Hispanic blacks and Hispanics gained coverage at the same rates as non-Hispanic whites. METHODS: To estimate changes in insurance rates, we employed a difference-in-difference regression approach comparing 7962 young adults aged 1…

The Longevity Gap Between Black and White Men in the United States at the Beginning and End of the 20th Century
Objectives. We sought to assess whether the disparity in mortality rates between Black and White men decreased from the beginning to the end of the 20th century. Methods. We used Cox proportional hazard models for mortality to estimate differences in longevity between Black and White Civil War veterans from 1900 to 1914 (using data from a pension program) and a later cohort of male participants (using data from the 1992 to 2006 Health and Retirem…
Effects of Diagnosed Dementia on Medicare and Medicaid Program Costs
This study examines the impacts of physician-diagnosed Alzheimer's disease and related dementias (ADRD) on Medicare and Medicaid program costs in 1994 and 1999. An innovative method is employed to estimate program payments over the life cycle starting at age 65. Using data from the 1994 and 1999 National Long-Term Care Surveys, merged Medicare claims, and national program data for Medicaid, we find that the share of total Medicare and Medicaid pa…
