Airline deregulation: What's behind the recent losses?

The recent disastrous financial performance of the airline industry is probably thought by many to indicate that deregulation is not workable. But simulations suggest that the current recession and the 1979 fuel price increase are primarily to blame. Deregulation has caused transitional losses for some segments of the industry; but the new freedoms accorded to the airlines probably have helped rather than hurt the profitability of the industry.
