The effects of advertising--lessons from optometry.

We examine the effect of advertising bans on the price of optometric examinations. Advertising is viewed as an information medium which enables consumers to search for lower prices, to the relative disadvantage of high-cost, low-volume sellers. Self-interest leads these sellers to support bans on advertising. An empirical section shows that price is 16 percent higher in states that ban optometric and optician price advertising, when examination length, procedures, and office equipment are held constant. The two advertising bans work by interaction--both must be present to raise significantly the price of eye examinations.

Refining physician manpower data.

Many conclusions about trends in physician manpower are based on the physician data set of the American Medical Association. Comparisons of specialty and activity status of physicians over time are hampered by changes in the AMA classification procedure in 1968 and growth in the "not classified" category since 1970. A method of adjusting data on physician manpower, taking into account these changes, is presented. The adjustments suggest that movements in the total physician supply away from patient care and primary care practice are overstated by use of unadjusted AMA data, and the percentage of physicians engaged in patient care has increased rather than decreased over the past decade.
