In a rare instance of real world experience confirming an academic hypothesis, Google has announced that it is setting up a for-profit charity. In this paper, which I discussed a few days ago (below), my coauthor and I argue that the for-profit charity might be a sensible, underexploited institution. In the course of the discussion, we ask why, if we are correct, there are no for-profit charities and we provide the obvious answer that the reason is tax discrimination. But Google’s plan suggest that the advantages of the for-profit form are strong enough to outweigh the tax disadvantages. The next step is for the government to recognize that tax discrimination on the basis of corporate form is unwise and to change the law.
