Matt Welch at the Reason blog takes credit for airline deregulation on behalf of libertarianism:
The “worldview” of libertarianism suggested, back in the early 1970s, that if you got the government out of the business of setting all airline ticket prices and composing all in-flight menus, then just maybe Americans who were not rich could soon enjoy air travel. At the time, people with much more imagination and pull than Gabriel Winant has now dismissed the idea as unrealistic, out-of-touch fantasia. They were wrong then, they continue to be wrong now about a thousand similar things, and history does not judge them harsh enough.
Mark Kleiman observes that transportation deregulation was more directly the progeny of 1970s Brookings-esque neoliberalism (though I’d grant Welch that libertarians got there first), though Kleiman doesn’t take issue with the basic claim that deregulating prices and service offerings “was, on balance, a good thing.” This argument ultimately rests on the declines in airfares and resulting democratization of air travel that Welch cites; indeed that’s what the Brookings-esque neoliberals I know cite when they’re defending the deregulatory record.
The catch is that all such economic comparisons must be counterfactual: they must show an improvement not with respect to CAB-set fares of the late-1970s, but rather with respect to what reasonably competent regulation could have produced under the other circumstances of the deregulated era. (This, FWIW, is one of Robert W. Fogel’s central insights into what makes economic history economic history.) If the comparison exercise is tough by the (inappropriate) historical yardstick thanks to declines in (average) service quality and the airline industry’s trail of fleeced stakeholders, then the counterfactual comparison is going to be tougher still thanks to a couple of factors that should have produced large declines in airline costs and hence fares even in the absence of deregulation.
The factors of note are a pair of technological advancements — the development of high bypass ratio turbofans suitable for shorter-haul airliners and the demise of the flight engineer’s job thanks to cockpit automation, both of which have origins predating deregulation — and the long secular decline in oil prices through the deregulated era’s zenith prior the crash of the 1990s stock market bubble. Since a regulator could have promoted adoption of the cost-saving technologies and passed the resulting productivity improvements and input cost decreases through to fare-payers using elementary regulatory technologies, deregulation must have produced substantial fare reductions relative to the late CAB era to have a claim to constituting a true improvement.
One of the airline industry’s problems is that it isn’t “revenue adequate” or able to recover its total costs including a normal return to investors. If you thought airlines were incurring costs efficiently, then moving towards revenue adequacy would require more revenues and hence higher average fares. On the face of things, that wouldn’t look good for a regulated alternative providing more secure revenues to the industry. However, there are dynamic efficiency counterbalances to the apparent static inefficiency under regulation: revenue adequacy implies having money for efficiency-improving investments. For instance, U.S. legacy airlines have somewhat notoriously kept relatively aged fleets in the air. Partly, that was a deliberate strategy that blew up when the Goldilocks conditions of the late-90s ended, and partly they don’t have the money to turn over their fleets as fast as they arguably should.
The formerly regulated transportation industries shared, to one extent or another, cost structures under which an efficient carrier would go broke under econ 101 perfect competition with prices driven down to marginal costs. So the question isn’t so much whether carriers will exercise such market power as they have in order to survive, but how. Real firms might or might not do that better than a real regulator. I do think there’s a good case to be made for some degree of pricing and service liberalization with regulatory policing of “excessive” use of market power; that’s a one-sentence version of the Staggers Act’s approach to the (very successful) freight rail industry.
Added: Good comments at Economist’s View, too, particularly a long one from Bruce Wilder expanding on the cost structure issue, discussing pricing strategies, and opining on the sources of apparent gains from deregulation.
