Transformation of the airline labor market continues long after deregulatio
n. Airline wages changed little immediately following deregulation, implyin
g either the absence of regulatory rents or maintenance of product market p
ower and union strength. Analysis for 1973-97, however, indicates that prio
r to recent gains, the relative earnings of air transport workers decreased
markedly during the latter half of the 1980s and the early 1990s. Some of
the earnings advantage of airline workers represents returns to occupationa
l skills and worker-specific quality. Labor rents are attributable largely
to union bargaining power, which, in turn, is constrained by the financial
health of carriers.
