To understand any economic system you have to understand the incentive structure. If you examine the incentives in our health care system, you can see why health care costs are out-of-control. The incentives for (1.) politicians, (2.) doctors and (3.) patients are currently designed to maximize wasteful, unnecessary health care spending.

(1.) A politician cannot run an election campaign without money. Consequently, politicians have designed our health care system to satisfy the medical lobbyists and maximize campaign contributions from the medical establishment.

(2.) Doctors really want to do what is best for their patients but are worried about malpractice law suits and end up ordering too many tests and procedures.

Market failure is not the fault of our doctors. It is the result of a poorly designed system with too much concentrated power and inadequate regulation. The "proof" that free enterprise can deliver desirable outcomes assumes free and equal information. It breaks down in the presence of special "insider" information such as that held by the medical establishment. Solving this problem is not easy, but the first step is to fully understand the problem.

Economic theory has traditionally assumed that all parties to a transaction have equal information. In an auction the seller and bidders have pretty much equal information about the item being auctioned off. In 2001 George Akerlof, Michael Spence and Joseph Stiglitz won the Nobel Prize in Economics for showing that asymmetric information can distort markets and result in market failure. The out-of-control costs of our current health care system provide a prime example of market failure due to (among other things) asymmetric information.

The classic example of symmetric versus asymmetric markets are the new car market versus the used car market. For our immediate purpose, we can substitute the health care market for the used car market to obtain an analogous comparison. A new car salesman would probably not try to convince you to buy a new car by telling you that if you fail to act today, your old car might fall apart at any moment. You obviously know more about your old car than the new car salesman does so there's no point in that strategy.

But what about your body? After all sorts of tests and procedures, the medical establishment knows more about your body than you do. Who are you to object to whatever they say you need? It is far from a normal economic market. With little private or public oversight, costs can get out of control really fast.

(3.) What about the recalcitrant patient who is unwilling to go along with unneeded pills, procedures and doctor visits because of the cost? Remember that the objective of the current health care system is to maximize the profits of the medical establishment in order to maximize the frequency and amount of their campaign contributions.

The way to solve the recalcitrant patient problem is to make sure that everyone has health insurance. That way, patients don't have to pay directly so they have nothing to lose except their time in going along with all the extras. Health insurance with no deductible and no co-pay serves to anesthetize the patient to ever higher health care costs.

What about all those television ads for every kind of drug imaginable? Are we being talked into drugs we don't really need or aren't really all that effective? President Eisenhower warned us about the military-industrial complex, but what about the medical-pharmaceutical complex? Does the prescription drug system go too far in transferring power to the medical establishment?

In summary health care costs are out-of-control resulting in "market failure" because:
(1.) Politicians are motivated to set up a system that maximizes the power of the medical establishment at the expense of everyone else;
(2.) Doctors are motivated to order all sorts of unnecessary tests, procedures and pills;
(3.) Patients are motivated to cooperate as long as it is all paid for by insurance. After all, it's all "free"!!!
