Costs under Regulation and Deregulation: The Case of US Passenger Airlines*

Privatization, the removal of regulatory control and similar changes in property rights within firms can be expected to shift cost functions downward and permit increased output, lower final service prices and more efficient resource allocation The US Airline Deregulation Act of 1978 was clearly expected to have these effects. This paper investigates whether the widely anticipated reduction in costs following the Airline Deregulation Act of 1978 actually occurred. We utilize an empirical procedure that explicitly takes the multi-product characteristics into account and identifies the various sources of changes in costs. The change in airline's costs are decomposed into components and separately measured to identify the effects attributable to deregulation A number of other countries are now considering important changes in the public ownership and control of their airline industries and a quantitative assessment of the actual effect of US deregulation on costs may be thought of as providing lower bound estimates of what might be expected in other countries.     

Short Term Econometric Forecasting and Seasonal Adjustment

Seasonal behaviour in the variables of an econometric model is usually handled in one of two ways—either the data are adjusted prior to estimation, or seasonal binary variables are included in the specification and estimation of the model. Although the literature on the subject is extensive, it is not obvious which of these procedures is best for forecasting. This paper compares the forecasting ability of a small model of the Australian economy for each of the alternative approaches to seasonal adjustment.     

Signaling and Takeover Deterrence with Stock Repurchases: Dutch Auctions versus Fixed Price Tender Offers

This article presents a model of repurchase tender offers in which firms choose between the Dutch auction method and the fixed price method. Dutch auction repurchases are more effective takeover deterrents, while fixed price repurchases are more effective signals of undervaluation. The model yields empirical implications regarding price effects of repurchases, likelihood of takeover, managerial compensation, and cross-sectional differences in the elasticity of the supply curve for shares.     

Why do NASDAQ Market Makers Avoid Odd-Eighth Quotes?

The NASDAQ multiple dealer market is designed to produce narrow bid-ask spreads through the competition for order flow among individual dealers. However, we find that odd-eighth quotes are virtually nonexistent for 70 of 100 actively traded NASDAQ securities, including Apple Computer and Lotus Development. The lack of odd-eighth quotes cannot be explained by the negotiation hypothesis of Harris (1991) , trading activity, or other variables thought to impact spreads. This result implies that the inside spread for a large number of NASDAQ stocks is at least $0.25 and raises the question of whether NASDAQ dealers implicitly collude to maintain wide spreads.     

MAPs: Labor-Based Peer Assistance in the Workplace

An offshoot of management-based Employee Assistance Programs, Member Assistance Programs (MAPs) are peer-based programs designed to help union members suffering from substance abuse and other personal problems. Although a relatively recent phenomenon, MAPs are rooted in traditional union principles of voluntarism and mutual aid. This article examines the emergence and growing popularity of MAPs, differences in MAP structure and orientation across unions, and the potential significance of MAPs to unions and industrial relations.     

Management Accounting and Service Industries: An Exploratory Account of Historical and Current Economic Contexts

Management accounting's development between 1880 and 1930 was rapid but subsequently truncated. This development was notable for its synergy with coincident economic and social changes and a reliance on impetus from the practical experiences of the members of other disciplines. Since World War II, advanced economies have become increasingly dependent upon their service sectors. The characteristics of service firms differ from those of manufacturers on a number of criteria including average number of employees. The accounting implications of these circumstances may include reappraisal of: the behavioural assumptions of management accounting; the roles of budgets; appropriate budget use styles; the utility of management accounting in ambiguous situations; and qualitative research into organizational contexts.     

A Re-Examination of Shareholder Wealth Effects of Calls of Convertible Preferred Stock

Common stock price reactions to announcements of 67 calls of in-the-money convertible preferred stocks are examined, and a significant average abnormal return of ?1.6 percent is documented. The finding is robust to the choice of estimation period and the assumed return-generating process. Annual dividend obligations for the called preferred issues in the sample typically are greater than the dividends for the common shares into which they are converted, and announcement-period abnormal returns are negatively correlated with changes in dividends. Moreover, calls that result in dilution of voting rights appear to have greater adverse valuation effects than calls that do not alter voting rights concentration.     

Estimating Private Equity Returns from Limited Partner Cash Flows

We introduce a methodology to estimate the historical time series of returns to investment in private equity funds. The approach requires only an unbalanced panel of cash contributions and distributions accruing to limited partners and is robust to sparse data. We decompose private equity returns from 1994 to 2015 into a component due to traded factors and a time‐varying private equity premium not spanned by publicly traded factors. We find cyclicality in private equity returns that differs according to fund type and is consistent with the conjecture that capital market segmentation contributes to private equity returns.
