Transformational leadership and job performance: A social identity perspective

Drawing on social identity theory, this study provides a model explaining the underlying process through which transformational leadership influences creative behavior and organizational citizenship behaviors. Individual differentiation and group identification are proposed as social identity mechanisms reflecting the characteristics of personal and collective identity orientations that underpin the differential effects of transformational leadership behaviors on performance outcomes. The model is tested with data from a sample of 250 front-line employees and their immediate managers working in five banks in the People's Republic of China. Results of hierarchical linear modeling provide support for the model whereby group-focused and individual-focused transformational leadership behaviors exert differential impacts on individual differentiation and group identification. Furthermore, individual differentiation mediates the relationship between individual-focused transformational leadership and creative behavior, whereas group identification mediates the relationships between group-focused transformational leadership and OCBs toward individuals and groups. Implications for theory and practice are discussed and future research directions are outlined.     

异地审计与审计定价——基于静态与动态视角的检验

地域特征是影响中国上市公司审计定价的重要因素。利用2004~2009年339家非金融行业上市公司组成的平衡面板样本,从静态和动态两个视角考察上市公司所在地与会计师事务所所在地的异同对审计定价的影响。研究发现,异地审计与审计定价显著负相关,中国证券市场确实存在"低价揽客"的现状。同时还发现,调整成本也是影响审计定价的重要因素。     

Risk aversion with state-dependent preferences in the rank-dependent expected utility theory

We extend the analysis of risk aversion with state-dependent preferences to the rank-dependent expected utility theory. We find that in this extended theory, for two preference relations to be comparable in risk aversion not only do their reference sets need to coincide (a condition first introduced by Karni [1983, 1985] in the original expected utility framework), but they must also rank the prospective state-dependent outcomes in the same manner. We formalize this additional condition by introducing the concept of certainty sets. Under our condition of comparability, various results and characterizations of interpersonal comparison of risk aversion are obtained. The implications for a specific insurance problem are also discussed.     

Ethical Judgment and Whistleblowing Intention: Examining the Moderating Role of Locus of Control

The growing body of whistleblowing literature includes many studies that have attempted to identify the individual level antecedents of whistleblowing behavior. However, cross-cultural differences in perceptions of the ethicality of whistleblowing affect the judgment of whistleblowing intention. This study ascertains how Chinese managers/professionals decide to blow the whistle in terms of their locus of control and subjective judgment regarding the intention of whistleblowing. Hypotheses that are derived from these speculations are tested with data on Chinese managers and professionals (n = 306). Statistical analysis largely supports the hypotheses, which suggests that an individual's locus of control does moderate the relationship between ethical judgment and whistleblowing.     

On the Feasibility of Unpopular Policies under Re-Election Concerns

A common concern about political decision making is that re-election concerns compel incumbent politicians to select policies that, although popular among the electorate, are inferior to available, less popular alternatives. Through studying a series of models, 1 find that, as long as politicians differ solely in the utility derived from holding office, there always exists an equilibrium where incumbents with strong re-election concerns still make efficient policy choices. However, when other aspects of heterogeneity among politicians are present, incumbents with strong re-election concerns may have the incentive to condition their decisions according to policy popularity. Suppose, for instance, some politicians are dumb in the sense that they are even more ignorant about policy efficacy than the public. To avoid being viewed as dumb, nondumb politicians (especially those with strong reelection concerns) may accept popular but inefficient policies or reject unpopular but efficient policies.     

Tradeoff on corporate cash holdings: a theoretical and empirical analysis

In this study, we propose an optimal cash holding model which examines the tradeoff between illiquidity and opportunity cost concerns as the benchmark to determine corporate excess cash. Through an optimization process, the optimal cash holdings suggested by our illiquidity–opportunity tradeoff model (IOT model) are endogenously determined. Different from many prior studies, the IOT model not only contains the value of cash, through market-based conception, but also adopts the modified Black–Scholes–Merton default probability of illiquidity. We then compare the IOT model with the Opler et al. (J Financ Econ 52(1):3–46, 1999) model (the OPSW model), which is a widely-used benchmark to determine excess cash, by using data for U.S. public firms from 1984 to 2014. The empirical results show that with regard to financial management the IOT model could be a better alternative to determine excess cash, even in light of different corporate characteristics and performance measures. Our conclusion suggests that while exploiting the value of marginal cash has attracted the attention of many recent studies, exploring the issue of optimal cash holdings is still important in the literature.     

Is the realized volatility good for option pricing during the recent financial crisis?

The contributions of this paper are threefold. The first contribution is the proposed logarithmic HAR (log-HAR) option-pricing model, which is more convenient compared with other option pricing models associated with realized volatility in terms of simpler estimation procedure. The second contribution is the test of the empirical implications of heterogeneous autoregressive model of the realized volatility (HAR)-type models in the S&P 500 index options market with comparison of the non-linear asymmetric GARCH option-pricing model, which is the best model in pricing options among generalized autoregressive conditional heteroskedastic-type models. The third contribution is the empirical analysis based on options traded from July 3, 2007 to December 31, 2008, a period covering a recent financial crisis. Overall, the HAR-type models successfully predict out-of-sample option prices because they are based on realized volatilities, which are closer to the expected volatility in financial markets. However, mixed results exist between the log-HAR and the heterogeneous auto-regressive gamma models in pricing options because the former is better than the latter in times of turmoil, whereas it is worse during the rather stable periods.     

Health and Income Variation – A Panel Data Study on the Developed and Less Developed Economies

In this paper, human capital in the form of ‘health status’ is introduced into a neoclassical economic growth model as one of the main factors differentiating rich and poor countries. Various panel data models are used to examine how health and other growth factors affect average income in different countries. Our main empirical finding indicates that a one-year increase in life expectancy (the health status measure) raises GDP per capita by 0.5–0.9%. Based on this result, a baseline health status can be established to help poor countries achieve a targeted economic growth rate.     

Efficiency and credit rating in Taiwan banking: data envelopment analysis estimation

In this article, we use the data envelopment analysis to measure the efficiency of banks before and after credit rating is taken into consideration and we also employ the Malmquist Productivity Index to measure the total factor productivity changes from 2001 to 2003. The results are as follows: (1) There is a positive relationship between the efficiency scores and credit rating, and thus, the credit rating can be a representative to evaluate the performance and quality of a bank; (2) We use the Wilconxon two-sample test of nonparametric statistic to test the influences of credit rating. The empirical result shows that the credit rating is proven to influence the efficiency of banks; (3) The efficiency scores improve in both investment grade (above tw BBB?) and speculation grade (under tw BBB?), when credit rating is taken into consideration. The empirical results show that the efficiency scores of banks with a high credit rating improved relatively more when compared to banks with a lower credit rating; (4) In this research we also adopt the Malmquist index to observe the productivity and efficiency changes from year to year. We obtain results whereby the improvement of efficiency may be influenced greatly both from pure technical and scale efficiency changes.
