Regional Versus Multilateral Solutions to Transboundary Environmental Problems: Insights from the Southeast Asian Haze

At an analytical level, economists have often categorised the international dimensions of environmental problems and policies as being national (or competitiveness), psychological (as opposed to physical) and transboundary (global) in nature. Focusing on transboundary pollution problems, the reasons why a multilateral approach among sovereign nations to solve such global externalities may be difficult are discussed within a simple analytical framework. The paper examines the Southeast Asian experience at a regional approach to tackling the haze problem due to the Indonesian forest fires. It goes on to explore multilateral policy options and constraints for dealing with such transboundary environmental pollution problems.     

Cue usage in financial statement fraud risk assessments: effects of technical knowledge and decision aid use

This paper investigates the effects of technical knowledge and decision aid use on financial statement fraud risk assessments made by directors and students. More extreme fraud risk assessments are made when participants identify and process larger (smaller) numbers of diagnostic (non‐diagnostic) factors, with technical knowledge driving diagnostic factor identification. Significant decision aid‐technical knowledge effects are also found; decision aid use has a detrimental effect on high‐knowledge directors while improving performance in inexperienced, low‐knowledge students. These results suggest that although decision aids can afford gains in performance in inexperienced users, they can have unintended and/or paradoxical behavioural effects on experienced users.     

Reversing an impairment loss and earnings management: The role of corporate governance

This paper examines whether the reversal of a previously recognized impairment loss provides an opportunity for earnings management, and whether such behavior is associated with managers' incentives. It also examines whether a corporate-governance mechanism can mitigate this behavior. Since 2005, listed companies in Taiwan have been required to comply with accounting standards, equivalent to International Accounting Standards (IAS) No. 36 “Impairment of Assets,” which allow reversals of asset-impairment losses. Data on a sample of 55 firms that reversed impairment losses between 2005 and the first quarter of 2007 were matched by industry and size with 55 control firms. Empirical results show that firms recognizing more impairment losses are more likely to reverse impairment losses when doing so would avoid an earnings decline in a subsequent period, which is consistent with the “cookie jar” reserve hypothesis. We also show that such behavior is more pronounced for firms with higher debt ratios, consistent with earnings management being associated with the incentive to avoid violation of debt covenants. However, an effective corporate governance mechanism could mitigate such behavior. Our study may contribute to the debate on global convergence with IFRS, especially convergence between IFRS and U.S. GAAP with respect to the “Impairment of Assets,” by providing a rationale for the latter's prohibition of reversals. It may also contribute to the corporate-governance literature by showing the effect of governance mechanisms on deterring earnings management.     

The impact of accounting information quality on the mispricing of accruals: The case of FRS3 in the UK

We exploit a unique setting of accounting regulation change to examine how accounting information quality affects the well-documented accrual anomaly. We show a significant reduction in the negative return predictability of accruals among UK companies with poorer accounting information quality following the introduction of Financial Reporting Standard No. 3: Reporting Financial Performance (FRS3). While the functional fixation hypothesis attributes the mispricing of accruals to the judgemental error of end-users of information, our findings suggest that the supply side of information also plays a crucial role. Our results provide evidence that regulatory interventions seeking to improve accounting information quality can reduce the mispricing of securities in the capital market.     

Marketing Period Risk in a Portfolio Context: Comment and Extension

This paper re-examines and extends the findings of Bond et al., Journal of Real Estate Finance and Economics, 34, 447–461, (2007) who consider the theoretical model of Lin and Vandell, Real Estate Economics, 35, 291–330, (2007) to determine the extent to which individual real estate asset return characteristics caused by marketing period risk disappear in a large, diversified real estate portfolio. The effects of marketing period risk are found to disappear in the limit with growth in the size of the portfolio, with ex ante variance approaching ex post variance, but only if the portfolio consists of nonsystematic risk alone, in which case both approach zero. The marketing period risk factor (MPRF), representing the ratio of ex ante to ex post variance, however, does not in general approach zero in the limit, in fact could increase or decrease depending upon the illiquidity characteristics of the individual assets and the magnitude and degree of correlation among individual property returns and marketing periods. The results suggest that even large institutional real estate portfolio managers must consider the illiquidity present in their portfolios and cannot assume that its effect will be diversified away.
