Article Abstract:
The Airline Deregulation Act of 1978 has had a significant impact on the airline industry and its labor market. The structure of the airline labor market before the Act is examined in light of certain significant historical events including legislative intervention and regulatory practice. The Act and other coincident extraneous events are considered to show how deregulation and other unrelated economic and technological factors operated as a catalyst, sparking substantial short-term upheaval in the airline labor market. It is argued that in the longer term airline employees have little to fear from deregulation and that deregulation ay eventually enhance labor's position in view of the increased employment opportunities that an expanded market may bring and the abolition of the industry strike insurance scheme.

Article Abstract:
Controversy surrounds the recent finding that college entrance exams are lower today than they were twenty years ago, but little empirical evidence has been offered in the debate. This paper uses cross-sectional regression analysis to examine the decline in SAT scores between 1972 and 1983. Three explanations are tested: the changing social environment, the financial resources devoted to education, and the emergence of militant teacher unions. The results show teacher unionism to be the most significant factor in the decline in scores. (Reprinted by permission of the publisher.)

Article Abstract:
Labor economists frequently misinterpret coefficients of variables in semilogarithmic regression equations. The proportional rates of change in the dependent variable that are implied by these coefficients are often erroneously assumed to be valid over arbitrarily large intervals. This note provides mathematical and empirical evidence on how serious the error can be. A simple formula is developed for making correct interpretations of semilog regression coefficients.
