Ethical instruction is critical for trainee accountants. Various teaching methods, both active and passive, are normally utilised when teaching accounting ethics. However, students’ learning styles are rarely assessed. This study evaluates the learning styles of accounting students and assesses the interaction of teaching methods and learning styles in an ethics instruction environment. The ethical attitudes and preferred learning styles of a cohort (137) of final year accounting students were evaluated pre-instruction. They were then subject to three different teaching methods while studying ethics during an auditing course. When ethical attitudes and preferred learning styles were re-assessed post-instruction, the teaching methods were found to have influenced active learners more than passive ones. Furthermore, when learning styles matched teaching methods used, usefulness was assessed as high but when learning styles and teaching methods differed, usefulness deteriorated significantly. Students displayed a preference for passive learning styles, despite being so advanced in their education. The implications are that instructors should consider learning styles before deciding on appropriate teaching methods, in accounting ethics environments. 相似文献

Predicting issuer credit ratings using a semiparametric method 总被引:1,自引:0,他引:1
This paper proposes a prediction method based on an ordered semiparametric probit model for credit risk forecast. The proposed prediction model is constructed by replacing the linear regression function in the usual ordered probit model with a semiparametric function, thus it allows for more flexible choice of regression function. The unknown parameters in the proposed prediction model are estimated by maximizing a local (weighted) log-likelihood function, and the resulting estimators are analyzed through their asymptotic biases and variances. A real data example for predicting issuer credit ratings is used to illustrate the proposed prediction method. The empirical result confirms that the new model compares favorably with the usual ordered probit model. 相似文献

This study develops an R&D-based growth model with vertical and horizontal innovation to shed some light on the current debate on whether patent protection stimulates or stifles innovation. We analyze the effects of patent protection in the form of blocking patents. We show that patent protection changes the direction of innovation by having asymmetric effects on vertical innovation (i.e., quality improvement) and horizontal innovation (i.e., variety expansion). Calibrating the model and simulating transition dynamics, we find that strengthening the effect of blocking patents stifles vertical innovation and decreases economic growth but increases social welfare due to an increase in horizontal innovation. In light of this finding, we argue that in order to properly analyze the growth and welfare implications of patents, it is important to consider their often neglected compositional effects on vertical and horizontal innovation. 相似文献

This paper investigates the driving forces, emission trends and reduction potential of China's carbon dioxide (CO2) emissions based on a provincial panel data set covering the years 1995 to 2009. A series of static and dynamic panel data models are estimated, and then an optimal forecasting model selected by out-of-sample criteria is used to forecast the emission trend and reduction potential up to 2020. The estimation results show that economic development, technology progress and industry structure are the most important factors affecting China's CO2 emissions, while the impacts of energy consumption structure, trade openness and urbanization level are negligible. The inverted U-shaped relationship between per capita CO2 emissions and economic development level is not strongly supported by the estimation results. The impact of capital adjustment speed is significant. Scenario simulations further show that per capita and aggregate CO2 emissions of China will increase continuously up to 2020 under any of the three scenarios developed in this study, but the reduction potential is large. 相似文献

This study examines the timing and speed with which inflation futures prices absorb inflation information. Results of the
study show that inflation futures prices already reflect the expected inflation. Moreover, 71% of unexpected inflation has
been reflected in futures prices about 25 business days prior to the Consumer Price Index (CPI) announcement, which usually
coincides with the end of the CPI measurement period. Reaction to the remaining 29% occurs on and shortly after the CPI announcement
date, especially on day 0 and day 2. The inflation risk premium that investors are willing to pay to avoid uncertain inflation
is estimated to be 1.41% per annum. 相似文献

Because of the lack of short‐term government bonds, the interbank repo market in China has been providing the best information about market‐driven short‐term interest rates since its inception. This article examines the behavior of the repo rates of various terms and their term premiums. The work in this article supplements the study by F. Longstaff (2000), which reports supportive evidence for the pure expectations hypothesis over the short range of the term structure with the use of repo data from the United States. It is found that the pure expectations hypothesis is statistically rejected, although the term premiums are economically small. It is shown that the short‐term repo rate, repo rate volatility, repo market liquidity, and repo rate spreads are all important in determining the term premiums. © 2006 Wiley Periodicals, Inc.
