Research Methods for Examining Independence Issues: Experimental and Economics-of-Auditing Approaches

Recent corporate failures in Australia and overseas have led many to question both the perceived and actual independence of auditors. We believe that it is unlikely that there is a general lack of independence among auditors or, at the other extreme, that there have been no breaches of independence. We suggest the need for research on factors that affect lack of actual independence. Research is also required on what factors affect independence as perceived by users of accounting reports. This paper outlines the research methods issues in the design of such studies.     

Cointegration and causal relationships among steel prices of Mainland China, Taiwan, and USA in the presence of multiple structural changes

Variation in the price of steel is an important factor to take into consideration when discussing cost control and management decisions in the construction industry. We employ various conventional and advanced econometrics methods to examine the interrelationships of steel prices in three related markets during the time period June 2002 to May 2010: Mainland China (CH), Taiwan (TW), and the United States (US). We adopt the Gregory and Hansen (GH) test and regime-switching (RS) model for cointegration, both of which accommodate endogenous structural break(s), to produce a more accurate analysis of a period in the presence of structural change(s). The empirical result of the RS cointegration test with respect to multiple structural breaks suggests a long-run equilibrium relationship among the three variables considered. This finding differs from the result of the GH test but confirms the result of the conventional Johansen test. Furthermore, the results of the Granger causality test indicate that both CH and US steel prices have great influence on the TW steel price; the Taiwanese steel market is closely linked with China and US steel markets in the long run.     

Selected Economic Analysis at the Antitrust Division: The Year in Review

Of the many activitiesof the Antitrust Division of theU.S. Department of Justice, we havesummarized some that raise interestingeconomic issues. We describe recentimprovements in the methodology to beused in ``coordinated effects' analysisof mergers. We also discuss four casesbrought by the DOJ that raise issues ofmarket definition, the influence ofcommon partial ownership of competitors,and the effects of fringe suppliers inconstraining collusion by large firms.     

Realisations of Venture Capital Investments: The Case of Management Buy-outs in the UK

One of the most rapidly developing sectors of the financial services industry in the UK has been venture capital, and with it the growth of management buy-outs. As these markets have matured, increasing attention is being paid to issues associated with the realisation of gains for both institutions and equity-holding management. This article seeks to contribute to this area by examining the issues involved in the realisation of investments in management buy-outs. Based on detailed interviews with 24 managers of buy-outs which have exited, and on information drawn from the Centre for Management Buy-out Research database, the article considers the relative merits of flotations, trade sales, capital restructurings, secondary buy-outs, share redemptions etc. The article also addresses the agency cost issues involved in controlling buy-outs to enable institutions to achieve realisation of their investments at a price and timing which enable their targets to be met.     

Sales promotion—playing to win?

In recent years, below‐the‐line promotion has begun to shed its “Cinderella” image, and is starting to attract the sort of marketing budgets and academic attention that was previously only given to mass‐media advertising. However, there is a general consensus that sales promotion is still neither managed effectively, nor understood thoroughly when compared to more high‐profile above‐the‐line promotion. Improving the understanding and use of sales promotion will require academics and practitioners to analyse and understand each of the very different below‐the‐line techniques and their individual merits. This article is one of two which takes a detailed look at the use of sales promotion competitions.
