A similar result occurs in a second arena—in the price-competitive industry, whose companies typically operate with very weak business franchises. In such industries, the free market “regulates” after-tax profits in a delayed and irregular, but generally effective, manner. The marketplace, in effect, performs much the same function in dealing with the price-competitive industry as the Public Utilities Commission does in dealing with electric utilities. In these industries, therefore, tax changes eventually affect prices more than profits.
