Contestability and Sustainability in Regional Airline Markets*

Since 1979, entry into the varied South Australian air passenger market has been unrestricted. This paper analyzes what has happened during the last four years with particular reference to the theory of contestable markets. Analysis shows that new firms have entered the market, services have increased significantly, new routes have been developed and that there is no apparent difference in the structure of fares on multi-firm and single-firm (monopoly) routes.     

GRAZING ON PUBLIC RANGELANDS: AN EVOLVING PROBLEM OF PROPERTY RIGHTS

Competition for publicly owned natural resources may be intensified when property rights are incomplete. Incomplete delineation of these rights among claimants to the various resource attributes of the public rangelands of the western United States has resulted in high transaction costs for capturing and/or protecting unassigned rights. This paper addresses how changes in the values society places on the public land resources have resulted in changes in the relative positions of various interest groups with respect to resource allocation decisions. The paper concludes by discussing implications of the property right approach for land management policies and grazing fees.     

Shelf Registrations and Shareholder Wealth: A Comparison of Shelf and Traditional Equity Offerings

This study examines the effect of issuing common stock on shareholder wealth under two alternative methods of registration, shelf registration under the Securities and Exchange Commission's Rule 415 and the traditional method of registering shares for immediate sale. The stock price reactions accompanying security registrations and offerings over the period from March 1982 through November 1983 are examined for over two hundred issues. A negative price reaction is observed for traditional and shelf registrations for both utility and non-utility issuers. No statistically significant difference is observed between shelf and traditional registrations. Further negative price reactions precede the offerings of these securities.     

The Behavior of the Interest Rate Differential Between Tax-exempt Revenue and General Obligation Bonds: A Test of Risk Preferences and Market Segmentation

This paper presents evidence that the yield differential between revenue bonds and similar general obligation bonds varies contracyclically with the level of economic activity. The evidence also indicates that significant investor-borrower induced market segmentation exists in the municipal bond market. An increase in the relative demand by commercial banks for tax-exempt securities and/or an increase in the supply of revenue bonds relative to the supply of general obligation bonds increase the yield spread between the two classes of debt. These findings were the result of a series of empirical tests with both macroeconomic and microeconomic data.     

Testing the Efficiency of the Canadian-U.S. Exchange Market under the Assumption of no Risk Premium

The efficiency of the Canadian-U.S. exchange market for the current float is examined more extensively than previously. Semi-strong-form tests which admit the lagged spot rate as a predictor are considered in addition to the standard weak-form test. These stronger tests reject the joint null hypothesis of an efficient exchange market and no risk premium for the period ending in October 1976, although not for the entire period. For almost every year the current spot rate provided a better forecast of the future spot rate than did the current forward rate.
