Tian, Wan and Guo (2002) explored the predictability and profitability of technical trading rules in markets with different efficiency levels; namely, the U.S. and China. In the case of the U.S. they found rules to have no predictability after 1975, whereas their results give support to technical trading rules having both predictability and profitability for the Chinese markets across the 1990's. The purpose of this paper is to extend the analysis of Tian et al. in two ways. First, to see if the conclusions extend to other markets – namely, the U.K., Hong Kong and Japan. Second, in the case of China, to examine whether the predictability and profitability of technical trading rules changed across the 1990's. On the basis of daily data Tian et al's results for the U.S. market are supported by the results for a number of the main developed markets where the technical trading rules had predictive ability during the 1970's that disappeared by the 1990's. Furthermore, the results suggest that while technical trading rules had short term predictive ability and profitability in the Chinese stock markets during the 1990's, this lessened as the decade progressed.

This paper examines the relationship between organizational ethical culture in two large international CPA firms, auditors' personal values and the ethical orientation that those values dictate, and judgments in ethical dilemmas typical of those that accountants face. Using an experimental task consisting of multiple judgments designed to vary in "moral intensity" (Jones, 1991), and unique as well as tried-and-true approaches to variable measurements, this study examined the judgments of more than three hundred participants in our study. ANCOVA and path analysis results indicate that: (1) Ethical judgments in situations of high moral intensity are affected by personal values and by environmental variables, such as the professional code of conduct (direct and indirect effects) and previous ethics instruction (direct effect only). (2) Corporate ethical culture, and a relatively strong firm rules-orientation, affect auditors' idealism but not relativism, and therefore indirectly affect ethical judgments. Jones' (1991) moral intensity argument is supported: differences in the characteristics of specific judgment tasks apparently result in different decision processes. 相似文献

Over the past decade, a number of accounting and financial reporting frauds have led to lost stock wealth, destroyed public trust, and a worldwide recession that called for necessary reform. Regulatory responses and systemic reforms quickly followed, and we show that, while necessary, these reforms are insufficient. The purpose of this paper is to forward virtuous professionalism as a necessary path toward restoring financial reporting systems. We take the position of external observer and analyze the accounting profession over time to assess what has transpired within our financial reporting systems. Our analysis reveals that the combined influence of commercialism and regulatory response has led to a systemic decline in accounting’s professional ideals and, as a result, an erosion of public trust. We then propose virtuous professionalism as a necessary process for restoring financial reporting systems based on sociological, professional, and philosophical theories. We argue that virtuous professionalism is necessary for restoring the public servant identity of the accounting professional. We conclude that efforts to restore financial reporting systems should begin with reforms that restore professional identity shaped by virtues. 相似文献

A two-step approach to account for unobserved spatial heterogeneity. Spatial Economic Analysis. Empirical analysis in economics often faces the difficulty that the data are correlated and heterogeneous in some unknown form. Spatial econometric models have been widely used to account for dependence structures, but the problem of directly dealing with unobserved spatial heterogeneity has been largely unexplored. The problem can be serious particularly if we have no prior information justified by economic theory. In this paper we propose a two-step procedure to identify endogenously spatial regimes in the first step and to account for spatial dependence in the second step. This procedure is applied to hedonic house price analysis. 相似文献

This paper argues that because United States inflation has been non-stationary over the past five decades the vast body of empirical research that proceeds without adequately accounting for the non-stationarity in the data is invalid. Using 50 years of United States inflation data the standard results in the Phillips curve literature are shown to be due to unaccounted shifts in the mean rates of inflation over the period. Short and long-run Phillips curves for the United States are then estimated using time series panel data techniques that account for these shifts in mean. 相似文献
