This paper uses data on health insurance choices by employees of Harvard University to examine the effect of alternative pricing rules on market equilibrium. In the mid-1990s, Harvard moved from a system of subsidizing more expensive insurance to a system of contributing an equal amount to each...

Using micro data on virtually all of the drugs and diseases of over 500,000 people enrolled in Puerto Rico's Medicaid program, we examine the impact of the vintage (original FDA approval year) of drugs used to treat a patient on the patient's 3-year probability of survival, controlling for...

Two key issues for public insurance policy are the effect of insurance status on medical treatment, and the implications of insurance-induced treat- ment differentials for health outcomes. We address these issues in the context of the treatment of childbirth, using Vital Statistics data on every...

Our previous study (Auerbach, Gokhale and Kotlikoff 1991) introduced the concept of generational accounting, a method of determining how the burden of fiscal policy falls on different generations. it found that fiscal policy in the U.S. is out of balance, in terms of projected generational...

U.S. policy changes and more optimistic fiscal forecasts have significantly improved the long-term fiscal prospects of the country. Nevertheless, these prospects remain dismal. Unless U.S. fiscal policy changes by a lot and very soon, our descendants will face rates of lifetime net taxation that...

Despite the presence of Medicare, out-of-pocket medical spending is a large expenditure risk facing the elderly. While women live longer than men, elderly women incur higher out-of-pocket medical spending than men at each age. In this paper, we examine whether differences in marital status and...

We estimate a model of drug demand and supply that incorporates insurance, advertising, and competition between branded and generic drugs within and across therapeutic classes. We use data on antiulcer drugs from 1991 to 2010. Our simulations show generics and ``me-too'' drugs each increased...

We demonstrate Medicare's influence on private insurers' payments for physicians' services. Using a large administrative change in payments for surgical versus medical care, we find that private prices follow Medicare's lead. A $1 change in Medicare's fees moved private prices by $1.16. A second...

I take advantage of regulatory and pricing dynamics in Medicare Part D to empirically explore interactions among adverse selection, switching costs, and regulation. I first document novel evidence of adverse selection and switching costs within Part D using detailed administrative data. I then...

We compare healthcare spending in public and private Medicare using newly available claims data from Medicare Advantage (MA) insurers. MA insurer revenues are 30 percent higher than their healthcare spending. Healthcare spending is 25 percent lower for MA enrollees than for enrollees in...
