Here is a Luigi Zingales post, “Why this blog?”:
By gathering information on the nature and cost of this subversion of competition, by distributing this information among the public at large, and by making this information salient, media outlets can reduce the power of vested interests. By exposing the distortions created by special interests, they can create the political demand for a competitive capitalism.
This is the goal of our Pro-Market blog: to educate the public about the many ways competition can be subverted. In this exercise our only goal is to make the market system work better. In the finest University of Chicago tradition, we will do it with data. We will try to do it with the rigor of the best academic work, but without the pedantry that often accompanies it. This blog will collect opinions, summarize work, and report on relevant research by Chicago faculty and Stigler fellows. We will use every medium at our disposal, because the message is our medium.
