DETERMINISTIC, STOCHASTIC, AND SEGMENTED TRENDS IN AGGREGATE OUTPUT: A CROSS-COUNTRY ANALYSIS

This paper examines whether output per capita in 126 countriesis better described as trend or difference stationary, usingappropriate finite-sample critical values. Depending upon whetherone uses solely a test with a trend stationary null, or solelyone with a difference stationary null, very different conclusionsare obtained. This outcome suggests that it is useful to considerthe tests complementary, rather than competing. We find thatwhen a definite characterization of GDP can be made, it is verylikely to indicate a difference stationary process. However,the likelihood of making definite conclusions does vary positivelywith both income level and data quality.     

THE RESPONSE OF STATUTORY FINANCIAL AUDITORS IN THE UK TO ENVIRONMENTAL ISSUES: A DESCRIPTIVE AND EXPLORATORY CASE STUDY

This paper explores the reaction of UK financial auditors to the growth of society's environmental awareness and attendant legislative pressures. The developing regulatory framework of auditing is briefly reviewed from an environmental perspective but the main contribution of the paper is to report the results of a series of interviews with a range of audit practitioners. The aim of the interviews was to explore: how, if at all, the conduct of the audit is changing (or, in the opinion of those interviewed, should change) in the light of environmental concerns: whether more training and guidance from professional bodies is sought; and views on regulation. Interviewees' experiences and their views of the impact of increasing environmental awareness and regulation on the statutory audit are reported and discussed. In addition, their views concerning a possible widening of their attestation role to encompass environmental reports are explored.     

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.     

A Note on Retrospectivity and the Tax System*

The legitimacy or otherwise of retrospective tax legislation has become a topical issue in Australian tax reform debates. This note considers the economic costs of permitting this budgetary practice. While under certain circumstances the standard welfare cost of the tax system may be reduced by retrospective announcement of tax arrangements, the costs of forming expectations. required by the possibility of retrospective tax legislation lead to a reduction in the value of economic activity.     

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.
