The subject of antitrust exemptions has been an oft-discussed topic here at TOTM (see, e.g. here and here).  In the latter of those two links I was somewhat critical of the DOJ for taking a neutral stance on the insurance industry exemption, which has now become rather wrapped up in the health care reform debate. I wrote…

Today’s Wall Street Journal includes a terrific article explaining why insider trading should be deregulated. Following up on last week’s high-profile insider trading charges, George Mason economist Don Boudreaux, whose Cafe Hayek posts are essential reading, succinctly sets forth the deregulatory position (which was first and most famously articulated by Geoff’s dad, Henry Manne).

Steve’s post responding to me and Josh on antitrust exemptions and buyer cartels raised a number of interesting issues.   A few points in response…

University of Chicago economist (and behavioralist doyen) Richard Thaler thinks “the question of whether a ‘public option’ should be part of the health care solution” is just “one big distraction.” In Sunday’s New York Times, Thaler argues that the debate over the public option is a “red herring” if, as President Obama insists, the public plan will have to break even and won’t be granted “the power to impose special deals with suppliers like hospitals and drug companies.” If those two conditions are satisfied, Thaler contends, the public plan is unlikely to have much success and certainly won’t drive out private insurers.

While the antitrust nerds of the world (including yours truly) have been all atwitter over Leegin’s renunciation of Dr. Miles, another antitrust decision from October Term 2006 may turn out to be more significant in the long run. I’m speaking of Weyerhaeuser Co. v. Ross-Simmons Hardwood Lumber Co., in which the Supreme Court considered whether predatory bidding plaintiffs must make the same two-part showing as predatory pricing plaintiffs (i.e., that the conduct at issue resulted in a below-cost price for the defendant’s products and that there was a dangerous probability that the defendant could recoup its short-term losses by exercising market power once rivals were vanquished). In answering that seemingly narrow question in the affirmative, the Court appears to have taken sides in antitrust’s greatest debate: how to define “exclusionary conduct” under Section 2 of the Sherman Act.

Steve Levitt thinks that tenure is overrated. But relative to what? Levitt proposes doing away with tenure because it distorts the incentives of scholars to front load their productivity and then ride off into the sunset after tenure is granted. Surely he is right about this incentive effect.

I recently picked up a copy of the July Harper’s Magazine to read an essay by Barry C. Lynn entitled, “Breaking the Chain: The Antitrust Case Against Wal-Mart.” If you can’t tell from the title, the basic point is that antitrust authorities should break up Wal-Mart and put an end to the immense havoc that the retail giant has caused the economy. There is very little in the way of actual analysis in the article. It is mostly hand waving about retail consolidation without economic coherence, with some dramatic parade-of-horribles-type hyberbole mixed in.
