What’s driving the high price of doctors: market inequality or government entry restrictions?  My co-bloggers’ debate reminds me of a random encounter with some striking evidence: The Digest of Education Statistics Table 294.

If you peruse this table, you’ll discover that total number of new M.D.s per year has been virtually flat for 30 years.  During this period, population increased over 30%.  As a result, the new M.D./population ratio has declined for decades.

If you’re still not convinced, know this: Over the last thirty years, new female M.D.s have sharply increased.  How is this possible given the stagnant total?  Because the number of new male M.D.s dropped like a rock!  New male M.D.s per person are down by over 45%.

My point, of course, is not that women have “stolen” men’s places in medical school.  My point, rather, is that that draconian government entry barriers are the only credible explanation of the facts.  Why else would the number of male doctors have fallen so far relative to demand?  Infinitely inelastic demand for medical services?  A massive decline in the talent of male applicants to medical school?!

As our population ages, we have naturally seen a large increase in the demand for doctors.  If the market for M.D.s worked normally, however, we would have fortuitously experienced a large offsetting supply shock: the rise of the female doctor.  Regulation has deprived us of this godsend – and deprived vast numbers of qualified men and women of the right to work in their preferred occupation.  Thanks to government entry barriers, demand has gone up and supply is frozen in place.  Consumers and taxpayers are paying a fortune for medical care.  And the problem is only going to get worse.
