Universal Health Insurance in Wisconsin

Over the past week, I have discussed California’s proposal to extend health insurance to all individuals. Today, I will examine—in my mind—a superior plan developed by former Republican Rep. Curt Gielow. According to a concept paper from the Wisconsin Health Plan website, the reforms will have the following impact: “All eligible Wisconsin residents receive a…

Terminator on Health Care: Part I

Last December, Governor Arnold Schwarzenegger held a press conference detailing some of the problems in the California health care system. For instance, there are 6.5 million California residents without insurance; the governor claims that individuals insurance premiums are about $500 higher (or $1200 for a family or four) than they would be if these uninsured…

HMO quality: Separating perception from reality

It has been shown in various studies and opinion polls that consumers generally believe that HMOs provide an inferior level of care than non-HMO plans. This is true even when more objective measures of medical service quality are taken into account. Why is HMO satisfaction so low? A study by Reschovsky, et al. (2002) claims…

Defining Managed Care

As insurance markets began to develop in the U.S., we observed two types of insurance emerging: indemnity plans and health maintenance organizations (HMOs).  Indemnity plans compensated providers on a fee-for-service basis and HMOs used a capitation scheme.  Typically, HMOs used gatekeepers to restrict services while indemnity plan restrictions were few and far between.  Typical analysis…

The doctor as a double agent

In modern medicine, doctors are agents for two distinct groups. The physician is an agent for the patient, but also an agent for insurance companies-especially in the managed care settings.  In balancing both relationships, the doctor must juggle the conflicting principal-agent problems of information asymmetry and third party payment.  Ake Blomqvist develops an interesting theoretical model to…

Physician Selection

Health economists frequently examine the effect of physician payment method on the provision of medical services.  It is often found that patients whose doctors are compensated via capitation or salaried schemes receive fewer services than patients whose doctors are compensated through a fee for service mechanism.  This finding is robust to a variety of medical settings…

Information on Referrals

Years ago, when someone needed care from a doctor they visited the physician directly whether they were a general practitioner or a specialist.  Nowadays, it is rarer for patients to visit a specialist without a referral.  The typical referral comes from a primary care physician, but it is also common for a specialist to refer…

Measuring adverse selection in managed health care

Introduction  Much of health care today is paid for by managed care plans.  If the managed care plans are profit maximizers–which I assume them to be–then they face a tradeoff.  By offering a lower quality of care, they will make more money; but lowering the quality of care reduces the demand for their insurance product. …

Information asymmetry, insurance and the decision to hospitalize

There is a dynamic relationship between generalists and specialists.  Currently, 4.5% of visits to PCPs result in a referral.  A RAND study and my own investigation of the 1998-1999 Community Tracking Survey show that about 10% of individuals are hospitalized at least once each year.  How should we model the decision patients face between generalist and specialist care.…
