I keep getting served a Facebook ad from the American Association of Medical Colleges imploring me to ask politicians to fund residency training for medical school graduates. The link leads to a webpage with neat graphics and a series of well-designed cartoons dramatizing an ominous shortage of 90,000 doctors expected to occur by 2025.
Now, the notion of “doctor shortage” by itself is meaningless. Doctors—like plumbers—are a scarce resource and therefore always in shortage. Patients have always had to contend with waiting rooms, whether at the outpatient clinic or in the emergency department. People have always had to wait to see a specialist, especially a good one, and this will never change. The supply of doctors must be judged in the context of the needs of patients and the economics of supply and demand.
But here’s the rub.
On May 18, the website of the Ludwig von Mises Institute ran a slightly edited version of this article. You can find it here
In its current usage, the phrase “dismal science” is a disparagement leveled against mainstream economics for its failure to provide a coherent account of economic activity.
According to Austrian school critics of the neo-Keynesian synthesis, this failure is in large part due to a foolish determination to bring into economics the mathematical precision of the physical sciences. To achieve this precision, neo-classical economists disproportionately focus their inquiry on global measures of economic activity: gross national product, aggregate demand, global supplies of money, goods, or labor, and other variables that lend themselves to quantification and numerical modeling. Lost in mainstream economic analysis is the attention due to the individual economic actor who, by virtue of his or her power of self-determination, is ill-suited for the equation or the graph.
A similar love affair with quantitative methods has rapidly taken over the medical field over the last several decades.
Shortly after its initial posting on this site, this article was also cross-posted
on the website the Ludwig von Mises Institute under the title “The Mayo Clinic and the Free Market.” I have made some very minor edits since then. MA. April 18, 2015.
Neoclassical economists such as Kenneth Arrow and Joseph Stiglitz tell us that the health care market is imperfect (or “Pareto inefficient”), meaning that the allocation of services is not optimal from the standpoint of social welfare. They point to information asymmetry as an important cause of this imperfection: patients cannot distinguish on their own the physician from the charlatan, the surgeon from the butcher, the remedy from the snake oil, the hospital from the coop. This may lead to moral hazard where the party with the most knowledge can provide inferior service with impunity.
To provide the necessary counterbalance for this “knowledge gap,” experts must be in charge of social institutions that tell patients where to go, who to see, how to be treated, and how much it should cost. This has been a principal and virtually unchallenged argument underpinning health care legislation in the last 100 years. In a famous paper he wrote on the subject in 1963, Arrow declared that “It is the general social consensus, clearly, that the laissez-faire solution for medicine is intolerable.”
But for those who wonder how intolerable the “laissez-faire solution” really is, a short booklet published in 1926 may prove instructive.

The New York Times recently published an opinion editorial entitled “Squandering Medicare’s Money” in which Dr. Rita Redberg, professor of cardiology at UCSF, proposes that much of Medicare’s financial deficit could be reduced if the government did not spend “a fortune each year on procedures that have no proven benefit.” To support her contention, Redberg cites several studies which indicate that many routinely performed tests and treatments do not improve patient outcomes in any measurable way, and are therefore “unnecessary.” Examples given are screening colonoscopies for patients over 75, PAP smears for women over 65, coronary stents for people with stable angina, and so forth. At an estimated cost of $150 billion, these procedures seem like obvious candidates for the deficit-reduction chopping block.
In 1961 the Framingham study investigators coined the term ‘risk factor’ and unwittingly ushered in a period in the history of medicine dominated by the advancement of risk modification as a strategy to prevent disease. Academic careers have succeeded and private enterprises have flourished on the promotion of this paradigm. Risk factor reversal is now an established surrogate for quality of care and the cornerstone of most ‘pay-for-performance’ schemes allegedly designed to improve health outcomes. One particular risk factor, however, stands out by virtue of the unusual treatment it receives from public health advocates.
