Set aside the moral issue of abortion for a moment, and just think of it as a medical-ish service. Dan Mitchell notes that the stability of the price of abortion illustrates the power of market forces, in contrast to the third-party payer problem for most health care:
Many people think that market forces don’t work in the health care system and that costs will always rise faster than prices for other goods and services. There are a few examples showing that this is not true, and proponents of liberalization usually cite cosmetic surgery [chart here] and laser-eye surgery as examples of treatments that generally are financed by out-of-pocket payments. Not surprisingly, prices for these treatments have been quite stable — particularly when increases in quality are added to the equation.
I just ran across another example, and this one could be important since it may resonate with those who normally are very suspicious of free markets. As the chart from the Alan Guttmacher Institute shows, the price of an abortion has been remarkably stable over the past 20-plus years. [Chart here.] Let’s connect the dots to make everything clear. Abortions generally are financed by out-of-pocket payments. People therefore have an incentive to shop carefully and get good value since they are spending their own money. And because market forces are allowed, the cost of abortions is stable. The logical conclusion to draw from this, of course, is that allowing market forces for other medical services will generate the same positive results in terms of cost and efficiency.
