The always-interesting Arnold Kling writes at TCSDaily:

That is the message that I take away from Clifford Winston's exhaustive survey of the actual results of well-intentioned government policies aimed at correcting market failures. He looks at policies designed to address all of the ills that economists and others have identified with markets -- monopoly power, imperfect information, externalities, and so on. Government tends to make things worse, not better.
