Decision Usefulness of Cash and Accrual Information: Public Sector Managers’ Perceptions

This study examines the usefulness of accrual accounting information for internal decision‐making contexts in the Western Australian public sector. Based on questionnaire responses of public sector managers, it was found that accrual accounting is perceived to be more useful than cash accounting in 16 of the 19 decision situations. These results suggest that the perceived usefulness of the accrual accounting system has improved with the passage of time. It may well be that perceptions of the usefulness of information derived from an accounting system will change over time as users gain familiarity and experience with a system.     

The Endogenity of the Optimum Currency Area Criteria

A country' suitability for entry into a currency union depends on a number of economic conditions. These include, inter alia , the intensity of trade with other potential members of the currency union, and the extent to which domestic business cycles are correlated with those of the other countries. But international trade patterns and international business cycle correlations are endogenous. This paper develops and investigates the relationship between the two phenomena. Using thirty years of data for twenty industrialised countries, we uncover a strong and striking empirical finding: countries with closer trade links tend to have more tightly correlated business cycles.     

The diversifiability of exchange risk

Discussions of the determinants of the spot or forward exchange rate frequently argue that holders of foreign assets that are subject to exchange risk must be compensated by a risk premium. This paper shows that much of exchange risk is diversifiable. If there are no outside assets and the value of the currency is uncorrelated with the value of other forms of wealth, then all exchange risk is diversifiable; there is no risk premium. More generally, there is a risk premium, but it need not be related to foreign indebtedness or to the variability of the exchange rate as commonly presumed.     

Determinants of state equity ownership,and its effect on value/performance: China's privatized firms

Evidence on the relationship between state ownership and performance in China's privatized firms is convex, concave and linear. Hence, the nature of this relationship is not resolved. This study examines this relationship for a larger, more recent sample of 4315 firm year observations of privatized Chinese firms during 1996–2003. Results support the hypothesis of a convex relationship between state ownership and performance showing benefits from strong privatization and state control. Not only is ownership structure found to affect performance, but also ownership concentration and balance of power jointly affect performance. Chinese firms with mixed control show significantly poorer performance than state or private controlled firms affirming the problem of ambiguity of ownership control, property rights, agency issues, profits and welfare objectives. New determinants of state ownership in China's firms are strategic importance, legal ownership, profitability, and market performance. Privatization benefits because there is a causal relation between ownership and performance.     

Analysis of ultra-high-frequency financial data using advanced Fourier transforms

This paper presents a novel application of advanced methods from Fourier analysis to the study of ultra-high-frequency financial data. The use of Lomb–Scargle Fourier transform, provides a robust framework to take into account the irregular spacing in time, minimising the computational effort. Likewise, it avoids complex model specifications (e.g. ACD or intensity models) or resorting to traditional methods, such as (linear or cubic) interpolation and regular resampling, which not only cause artifacts in the data and loss of information, but also lead to the generation and use of spurious information.     

Cost-Effectiveness of Alternative Integrated Pest Management Extension Methods: An Example from Bangladesh

This study examines the cost-effectiveness of alternative methods for diffusing integrated pest management practices in Bangladesh. Methods compared include farmer field schools, field days, and extension agent visits. Farmer field school participants were more likely to adopt integrated pest management practices than recipients of messages from field days and agent visits. However, due to lower costs per participant, field days were the most cost-effective means for stimulating adoption of simpler practices and extension agent visits were the most cost-effective for extending more complex practices.
