A canonical correlation analysis of carrier financial strategy: The case of airline deregulation

This study investigates U.S. airline managements' perception of deregulation's impact upon the industry's financial risk by analyzing the airlines' risk management behavior. Specifically, canonical correlation analysis is utilized to ascertain key asset-liability/equity interrelationships and to identify changes in airline risk management as indicated by changes in financial structure. A control sample of nonregulated firms in various service industries is used to separate the effects of general economic conditions from those of deregulation. The results indicate that the airline industry adjusted its financial structure to reduce the industry's exposure to risk as the industry became deregulated. The industry decreased its financial leverage through greater use of equity vis-à-vis debt to finance its long-term assets while simultaneously increasing its liquidity. Definitive conclusions concerning the industry's perception of financial risk after deregulation had been in place a few years are precluded by two external events which occurred in 1978—the requirement that leases be capitalized on the balance sheet and the rapid fuel price increases spurred by the Iran-Iraq war. However, the results clearly show the industry perceived greater financial risk during the early years of de facto CAB deregulation.
