This article examines how the frequency of board committee meetings impacts on Australian firms' financial performance. Data were collected from 118 Australian listed companies – including 26 financial firms and 92 nonfinancial firms – for the period 1999–2007. Analysis of that data shows that the frequencies of audit committee meetings and remuneration committee meetings are positively and significantly associated with return on equity and return on assets. The frequencies of risk committee meetings do not show any significant effects on the financial performance of Australian firms. Estimated results are found to be robust after controlling for internal as well as external governance mechanisms that might affect Australian firm performance.  相似文献

A new method for forecasting the trend of time series, based on mixture of MLP experts, is presented. In this paper, three neural network combining methods and an Adaptive Network-Based Fuzzy Inference System (ANFIS) are applied to trend forecasting in the Tehran stock exchange. There are two experiments in this study. In experiment I, the time series data are the Kharg petrochemical company’s daily closing prices on the Tehran stock exchange. In this case study, which considers different schemes for forecasting the trend of the time series, the recognition rates are 75.97%, 77.13% and 81.64% for stacked generalization, modified stacked generalization and ANFIS, respectively. Using the mixture of MLP experts (ME) scheme, the recognition rate is strongly increased to 86.35%. A gain and loss analysis is also used, showing the relative forecasting success of the ME method with and without rejection criteria, compared to a simple buy and hold approach. In experiment II, the time series data are the daily closing prices of 37 companies on the Tehran stock exchange. This experiment is conducted to verify the results of experiment I and to show the efficiency of the ME method compared to stacked generalization, modified stacked generalization and ANFIS.  相似文献

AIRCO is a manufacturer of industrial air conditioner units whose management is concerned that their current traditional cost accounting (TCA) system is not accurately representing their product cost behavior. Under certain operating conditions, an activity based costing (ABC) system can provide relevant and accurate indirect cost information that assists in making customer, product, and process improvement decisions. An ABC system was successfully developed for AIRCO that indicated that their products do not consume overhead costs on a volume basis as represented by their current TCA system. Valuable product and process information were obtained. This case study details the development process that was used and the results that were obtained during the ABC analysis.  相似文献

In the present paper, the impact of genetically modified (GM) food production on producers, consumers and trade in New Zealand is simulated under various scenarios using the Lincoln Trade and Environment Model (LTEM). The LTEM simulates, against various assumptions of proportions of GM/GM-free production, the impact of various scenarios relating to preference for or against GM production. The results from this preliminary analysis show that the greatest positive impact on New Zealand income is from following a GM-free strategy, where it is assumed such markets as the European Union and Japan have a large switch in preference away from GM food, followed by the scenario when there is a 20% preference for GM-free.  相似文献

Contrary to economic theory, there is international evidence that common stock returns and inflation are negatively related. This negative relationship is examined in this paper and the applicability of the risk premium hypothesis is tested. According to this hypothesis, an increase in unanticipated inflation causes the market risk premium to rise, which in turn lowers current stock prices. A model is developed and the effect of uncertain inflation on the market risk premium across four countries is tested empirically. Results indicate that the market risk premium is positively related to uncertain inflation.  相似文献

Since 1992, the national business systems (NBS) approach has been increasingly used to analyse not only firm characteristics, structures and strategies within NBS, but also the nature of international business and its interactions with both national and transnational institutions. In reviewing 25 years of NBS literature, we heed calls in IB journals urging researchers to use NBS notions and findings in IB research. Our systematic review of 96 articles analyses the patterns and contributions of NBS literature, revealing four thematic junctures: (1) comparative business systems, (2) firm internationalisation and the management/organisation inside MNCs, (3) the role of internationalisation in the development of organisational capabilities and innovation and (4) the emergence of transnational communities in and across firms and societies. Themes are described in terms of (a) the research questions (RQ) they focus on, (b) how NBS approach investigates the RQ and what are the major findings, (c) how IB frames and approaches the same RQ, (d) how does the NBS approach extend the perspectives of IB and (e) what are the problems faced by NBS in terms of developing further insights into the RQ. Our review contributes to the recent endeavour of IB research to institutionalism, encouraging a productive dialogue between IB and NBS research.  相似文献
