Modelling Accounting Populations for Ratio Estimation in Audit Sampling

The classical ratio estimator is one of the auxiliary information estimators frequently discussed in the audit sampling literature. The major weakness of this estimator is its unreliability when accounting populations have only one-sided errors or when the error rate is low. Efforts have been made to improve the classical estimator by using techniques such as the Jackknifed ratio discussed by Frost and Tamura (1982). This paper proposes a new method to estimate the population total error based on the ratio of error over book value, i.e., taintings.

The special features of the proposed procedure are that (1) it specifically models the special characteristics of the typical accounting populations, and (2) it is the first study we know of in the audit sampling literature that uses simulation to capture the characteristics of the specific distribution of the estimator each time a confidence interval is constructed. This new approach became possible because of the recent publication of several studies on the empirical characteristics of accounting errors. Results of empirical tests indicate that the proposed method can significantly improve the reliability of the classical ratio under circumstances where the classical ratio needs improvements. Empirical comparisons are also made with a third ratio estimator under dollar-unit sampling. Again, the proposed method provides better reliability.     

Cointegration and causal relationships among steel prices of Mainland China, Taiwan, and USA in the presence of multiple structural changes

Variation in the price of steel is an important factor to take into consideration when discussing cost control and management decisions in the construction industry. We employ various conventional and advanced econometrics methods to examine the interrelationships of steel prices in three related markets during the time period June 2002 to May 2010: Mainland China (CH), Taiwan (TW), and the United States (US). We adopt the Gregory and Hansen (GH) test and regime-switching (RS) model for cointegration, both of which accommodate endogenous structural break(s), to produce a more accurate analysis of a period in the presence of structural change(s). The empirical result of the RS cointegration test with respect to multiple structural breaks suggests a long-run equilibrium relationship among the three variables considered. This finding differs from the result of the GH test but confirms the result of the conventional Johansen test. Furthermore, the results of the Granger causality test indicate that both CH and US steel prices have great influence on the TW steel price; the Taiwanese steel market is closely linked with China and US steel markets in the long run.     

Government ownership,corporate governance and tax aggressiveness: evidence from China

This study investigates how government ownership and corporate governance influence a firm's tax aggressiveness. Using Chinese listed companies during 2003–2009, we find that compared with government‐controlled firms, non‐government‐controlled firms pursue a more aggressive tax strategy. In particular, non‐government‐controlled firms with a higher percentage of the board shareholdings and with a CEO who also serves as the board chairman are more aggressive. For government‐controlled firms, we find that board shareholding has an impact on tax aggressiveness and it does not differ between local and central government‐controlled firms. However, local government‐controlled firms in less developed regions where the implementation of corporate governance measures is generally less effective are more tax aggressive than those in other regions.     

Why Celebrity Sells: A Dual Entertainment Path Model of Brand Endorsement

This article introduces a dual entertainment path model that integrates insights from media entertainment and transportation theory to show how links between entertainment motives (aspirational and playful) and experiences (celebrity fantasy and emotional investment) influence endorsed brand attitude. Results of two studies validate the salience of two paths. Fans, who hold parasocial bond with the celebrity, are driven by both aspirational and playful motives to engage in celebrity-induced entertainment experiences. Nonfans lack aspirational motive and are driven predominantly by playful motive. In either situation, celebrity-induced entertainment experiences enhance endorsed brand attitude. This model complements the existing celebrity endorsement literature by positing entertainment as a salient dimension of brand endorser effects. Its findings provide new insights on how advertisers promote their brands.     

A Note on Allen’s Arc Elasticity with Arithmetic, Geometric and Harmonic Means

Discussion and debate on the application of Allen??s arc elasticity has continued into the 21st century. This note demonstrates three points. First, perceived differences between Allen??s geometric mean elasticity and a constant demand elasticity based on an assumed isoelastic demand curve are negligible for small changes in price and quantity, which comprise the vast majority of such changes. Second, in some cases of rapid security or commodity price movements, the harmonic mean may provide the most accurate elasticity estimates across measures of central tendency. Third, because the arithmetic and harmonic means serve as bounds for the geometric mean, an elasticity based on the geometric mean may be considered a prudent choice among these three on this basis alone.     

Australian consumer attitudes to health claim – food product compatibility for functional foods

This study with Australian consumers investigated how appealing different health claims combined with particular food carriers were to Australian consumers, and compared the results of a similar study with Dutch consumers. 149 shoppers considered up to 30 different food concepts, rating how ‘attractive’, ‘believable’, and ‘new and different’ they found each concept and their ‘intention to try’. Each variable was significantly related to intention to try (p < 0.001) and together explained 56% of the intention score. Claims and carriers independently had a significant effect on ratings of attractiveness and intention to try but, unlike the Dutch study, the carrier was a more important predictor of intention to purchase than the claim. Implications for regulation of health claims for food are discussed.     

Social capital and creativity in R&D project teams

The existing research contributes to our understanding about the value of social capital in a wide range of social science disciplines; however, it does not well address the role of social capital in creativity for research and development (R&D) project teams in a given context. Using a sample of 54 R&D project teams in high-technology firms of Taiwan, we examined the impacts of social capital on creativity of R&D project teams from an intra-team perspective. Results of factor analysis revealed four factors extracted from the concept of social capital, namely social interaction, network ties, mutual trust, and shared goals. Findings suggested that social interaction and network ties had significant and positive impacts on creativity of R&D project teams, but mutual trust and shared goals did not. Managerial implications for managing social capital in R&D project teams are discussed.     

An International Asset Pricing Model with Time-Varying Hedging Risk

This paper employs a two-factor international equilibrium asset pricing model to examine the pricing relationships among the world's five largest equity markets. In addition to the traditional market factor premium, a hedging factor premium is included as the second factor to explain the relationship between risks and returns in the international stock markets. Moreover, a GARCH parameterization is adopted to characterize the general dynamics of the conditional second moments. The results suggest that the additional hedging risk premium is needed to explain rates of return on international equities. Furthermore, the restriction that the coefficient on the hedge-portfolio covariance is one smaller than the coefficient on the market-portfolio covariance can not be rejected. This suggests that the intertemporal asset pricing model proposed by Campbell (1993) can be used to explain the returns on the five largest stock market indices.     

Investigating the factors influencing small online vendors’ intention to continue engaging in social commerce

ABSTRACT

This study investigates the variables that determine small online vendors’ intentions to continue engaging in social commerce. Based on the theory of planned behavior (TPB) and social exchange theory (SET), eight hypotheses were developed to (1) identify the antecedents that influence small online vendors’ attitudes toward social commerce, subjective norms, and perceived behavioral control; and (2) examine the causal relationships among the variables with respect for continuous usage intention. A questionnaire survey was used to collect data on a sample of 166 small online vendor managers and employees. Partial least squares (PLS) was used to validate the proposed model. The findings show that social exchange factors (perceived benefits and commitment) significantly affect small vendors’ attitudes toward social commerce. The results further confirm the validity of TPB, i.e., attitude and perceived behavioral control have significant impacts on continuous usage intention in relation to social commerce. The findings of this study provide important insights into the antecedents of attitude for academics and practitioners, application of social computing in commerce for engaging in service innovation, and have the potential to contribute to the development of effective online marketing strategies.
