insurances Inherent problems with private insurance Any private insurance system will face two inherent challenges: adverse selection and ex-post moral hazard. Adverse selection Insurance companies use the term "adverse selection" to describe the tendency for only those who will benefit from insurance to buy it. Specifically when talking about health insurance, unhealthy people are more likely to purchase health insurance because they anticipate large medical bills. On the other side, people who consider themselves to be reasonably healthy may decide that medical insurance is an unnecessary expense; if they see the doctor once a year and it costs $250, that's much better than making monthly insurance payments of $400 (example figures). The fundamental concept of insurance is that it balances costs across a large, random sample of individuals (see risk pool). For instance, an insurance company has a pool of 1000 randomly selected subscribers, each paying $100 per month. One person becomes very ill while the others stay healthy, allowing the insurance company to use the money paid by the healthy people to pay for the treatment costs of the sick person. Adverse selection upsets this balance between healthy and sick subscribers by leaving an insurance company with primarily sick subscribers and no way to balance out the cost of their medical expenses with a large number of healthy subscribers. Because of adverse selection, insurance companies use a patient's medical history to screen out persons with pre-existing medical conditions. Before buying health insurance, a person typically fills out a comprehensive medical history form that asks whether the person smokes, how much the person weighs, whether the person has been treated for any of a long list of diseases and so on. In general, those who look like they will be large financial burdens are denied coverage or charged high premiums to compensate. On the other side, applicants can actually get discounts if they do not smoke and are healthy. Starting in 1976, some states started providing guaranteed-issuance risk pools, which allow individuals who are medically-uninsurable through private health insurance to be able to purchase a state-sponsored health insurance plan, usually at higher cost. Minnesota was the first to offer such a plan, and there are now 34 states which do. Plans vary greatly from state to state, both in their costs and benefits to consumers and to their methods of funding and operating. They serve a very small portion of the uninsurable market -- about 183,000 people in the USA [citation needed]-- but in best cases do allow people with pre-existing conditions such as cancer, diabetes, heart disease or other chronic illnesses to be able to switch jobs or seek self-employment without fear of being without health care benefits. Efforts to pass a national pool have as yet been unsuccessful, but some federal tax money has been awarded to states to innovate and improve their plans. Moral hazard Moral hazard describes the state of mind and change in behavior that results from a person's knowledge that if something bad were to happen, the out-of-pocket expenses would be mitigated by an insurance policy--in this case, one which provides reduced prices for medical care. In most cases the carriers have a 2 year window to go back and consider a condition pre-existing. Other factors affecting insurance price Because of advances in medicine and medical technology, medical treatment is more expensive, and people in developed countries are living longer. The population of those countries is aging, and a larger group of senior citizens requires more medical care than a young healthier population. (A similar rise in costs is evident in Social Security in the United States.) These factors cause an increase in the price of health insurance. Some other factors that cause an increase in health insurance prices are health related: insufficient exercise; unhealthy food choices; a shortage of doctors in impoverished or rural areas; excessive alcohol use, smoking, street drugs, obesity, among some parts of the population; and the modern sedentary lifestyle of the middle classes. In theory, people could lower health insurance prices by doing the opposite of the above; that is, by exercising, eating healthy food, avoiding addictive substances, etc. Healthier lifestyles protect the body from some, although not all, diseases, and with fewer diseases, the expenses borne by insurance companies would likely drop. A program for addressing increasing premiums, dubbed "consumer driven health care," encourages Americans to buy high-deductible, lower-premium insurance plans in exchange for tax benefits and utilization of Health Incentive accounts. |
