Consolidation in the Health Insurance Market

Dealbook notes the acquisition of Coventry Health Care by Aetna as a trend in this sector:

Aetna’s acquisition of Coventry is the latest deal in an industry that has been spurred to consolidation in part because of the Obama administration’s sweeping expansion of health care coverage in the country. Last month, WellPoint agreed to buy Amerigroup for about $4.9 billion.

Before Mitt Romney decided that Medicare cost containment was something to dishonestly campaign against, Paul Ryan and President Obama were both proposing that cost containment was a good idea. The difference perhaps was that the President’s idea for doing so involved price controls while the Republicans wanted to rely on more competition. Consolidation, however, is often a euphemism for the larger players to increase their market share on the hope of reducing competition. If these Republicans are serious about relying on competition – shouldn’t they be condemning this consolidation? Update: A hat tip to a devoted reader of Mark Thoma’s blog named Anne for providing us with a link to James C. Robinson who discusses the consolidation in the hospital sector.
