Welfare Reform Reduced Public Coverage Increased Employer Coverage Among Immigrants

HTML Version

Eight years after passage of the 1996 federal welfare reform law, researchers and policymakers still debate the effects of the legislation. Cuts in benefits for immigrants were part of the changes to the welfare system, raising concerns that already high rates of uninsurance among immigrants could soar. New research shows that, contrary to conventional wisdom, moving welfare recipients off the public assistance rolls did not necessarily leave immigrants without health insurance coverage. While welfare reform reduced the level of Medicaid coverage for immigrants as a whole, many were able to obtain employer-sponsored coverage (ESI). Residents in states with less generous public assistance benefits were significantly more likely to have ESI than immigrants living in states that offered more generous aid.

How Many Are Uninsured? Different Data Offer Different Dimensions

HTML version

Many of us have become comfortable thinking about “the uninsured” in terms of the statistic reported by the annual Current Population Survey—43.6million in 2002. The CPS number is a useful estimate of year-to-year change, but masks key information. The number and composition of the uninsured changes dramatically if you look at the uninsured during a particular month rather than over an entire year. Getting accurate and timely estimates of how many people experience what kinds of spells of uninsurance is important in order to craft effective policies for the uninsured. Further, those uninsured all year differ from those individuals who lose coverage for only part of the year.

Rising Uninsured Rates: It's Employment, Not the Economy, Stupid

HTML version

The current economic recovery may not yet be good news for Americans looking to keep or gain back their health insurance coverage. Researchers warn that the threat of becoming or remaining uninsured is substantial, even when the economy is improving. The most recent recession ended in November 2001, but unemployment continued to rise through June 2003. The economic downturn led to more than one million Americans losing coverage during the recession, and the economy has yet to make up for these losses more than two years into the recovery.

Q&A with John Cawley, Ph.D. (HTML)

Read more about why John Cawley, who co-authored the paper Health Insurance Coverage and the Macroeconomy for ERIU, believes that it's employment, not the economy, that matters in determining workers' health insurance status.

No Bang for the Buck: Subsidizing Workers' Premiums to Reduce Uninsured

HTML Version

About one-quarter of those who lack health insurance live in a household in which someone declined to take coverage offered at work. On the surface, targeting those who currently are offered health insurance and subsidizing their premiums appears to be an easy way to increase rates of insurance coverage. However, new research suggests this might not be the case.

Can the Employer-Based Health Insurance System Reduce America's Uninsured?

HTML Version

Policymakers continually look to the employer-based health insurance system when proposing new solutions to reduce the number of uninsured Americans. Unfortunately, the solution to this ever growing problem is not that simple. There are many employee- and employer-based factors to consider, and much that we don't yet know about how employers and employees respond to different financial incentives.

Q & A with Linda Blumberg, Ph.D. (HTML)

Read more about why Dr. Blumberg, who co-wrote the paper "Can the Employer-Based Health Insurance System Reduce America's Uninsured?" for ERIU, believes that increasing insurance coverage through tax credits and subsidies is not as easy as it sounds.


Jumping to Conclusions: Will Expanding Health Care Insurance Improve the Health of the Uninsured?

HTML Version

Hundreds of studies document that people without health insurance have worse outcomes than those with coverage. Is this evidence enough to conclude that having health insurance would improve the health of the uninsured?

Q&A with David Meltzer, M.D., Ph.D. (HTML)

Read more about why Dr. Meltzer, who co-wrote the paper "What Do We Really Know About Whether Health Insurance Affects Health?" for ERIU, believes we know less about the best ways to improve the health of the uninsured than we think we know.


A Revolving Door: How Individuals Move In and Out of Health Insurance Coverage

Many health care experts think of the more than 41 million Americans without health care coverage as a group of chronically uninsurable individuals whose status rarely changes. However, longitudinal research shows that the uninsured are a dynamic, diverse, and constantly evolving pool of people--and that over a two-year period, actually 80 million Americans lack health insurance at some point.

Q&A with Pamela Farley Short, Ph.D. (HTML)

Read more about why Dr. Short, Professor of Health Policy and Administration at Pennsylvania State University, who recently wrote the paper "Counting and Characterizing the Uninsured" for ERIU, believes it's critical that policymakers understand who comprises the uninsured.
