As described in the current Cato Policy Report, one of the “Hard Lessons from the Auto Bailout” is that management at GM is likely to be “highly erratic, as the president and Congress wrestle for decisionmaking primacy at this majority taxpayer-owned entity.” The “dealerships” issue is Exhibit A.

One of GM’s first decisions upon emerging from bankruptcy was to announce closures of a number of dealerships to help reduce costs. Then-nominal-CEO Fritz Henderson explained that the planned closings would save GM about $100 in distribution costs per vehicle–a few hundred million dollars per year when factoring in the millions of units GM expects to produce.

But many of GM’s congressional CEOs cried foul, demanding reconsideration from a company that had taken public funds. The House of Representatives even passed a bill requiring companies that received federal funds to reestablish terminated dealership agreements, though no action was taken in the Senate.

However, as reported in The Hill today, Congress is fast-tracking legislation to restrict GM’s (and Chrysler’s) closings, by subjecting each decision to an arbitrator, who will “balance the economic interests of the terminated dealership, the car companies and the general public.” A Senate aide is cited as saying legislators intend to pass this measure before Christmas.

Well, look, EVERY decision GM makes will produce winners and losers in terms of real and opportunity costs. Hence, EVERY decision is just as worthy of legislative or executive scrutiny, if the dealership issue is the litmus test.

With 537 CEOs, all but one of whom have bigger priorities than GM’s bottom line, GM’s future will be dictated by splitting differences, political logrolling, and managing by consensus–tactics that will assure GM’s demise.
