身份“差序格局”的测量及其效应研究

文章以文献研究和深度访谈为基础,结合问卷调查所获的数据资料,编制了员工身份“差序格局”问卷。274份有效问卷的探索性因子分析表明,身份“差序格局”包括经济剥夺感、差序对待感和权力偏移感3个维度。为了进一步验证身份“差序格局”的构想效度,并考察问卷的信度与校标效度,对74家企事业单位进行了调查,获得了519份有效问卷。验证性因子分析结果支持身份“差序格局”问卷的结构,信度和多元回归分析的结果显示,身份“差序格局”问卷具有较好的信度和效度。最后,结合本土文化情境,围绕身份“差序格局”对组织不公正、组织负向认同、伤感度和反生产行为的差异化效应及其诱因进行分类梳理,强化了身份“差序格局”结构的说服力和解释力。

Interpoint Distance Test of Homogeneity for Multivariate Mixture Models

Finite mixtures offer a rich class of distributions for modelling of a variety of random phenomena in numerous fields of study. Using the sample interpoint distances (IPDs), we propose the IPD‐test statistic for testing the hypothesis of homogeneity of mixture of multivariate power series distribution or multivariate normal distribution. We derive the distribution of the IPDs that are drawn from a finite mixture of the multivariate power series distribution and multivariate normal distribution. Based on the empirical distribution of the IPDs, we construct a bootstrap test of homogeneity for other multivariate finite mixture models. The IPD test is applied to mixture models for matrix‐valued distributions and a test of homogeneity for Wishart mixture is presented. Numerical comparisons show that IPD test has accurate type I errors and is more powerful in most multivariate cases than the expectation–maximization (EM) test and modified likelihood ratio test.     

Vertical separation of transmission control and market efficiency in the wholesale electricity market

This study examines how vertical separation of transmission control affects the wholesale market efficiency in the electric power industry. We analyze a unique regional electricity wholesale market in the U.S. where initially restructuring only occurred in the transmission sector. Following a commonly-used best dispatch model (Wolfram, 1999; Borenstein et al., 2002), we simulate competitive benchmark prices and compare with the best estimates available for actual prices to measure price-cost markups of the wholesale market. Empirical results demonstrate that the vertical separation of transmission control led to a significant increase in market markups in peak-load hours, documenting evidence of enhanced market power. Although we also find a reduction in the price-cost margin in low-demand hours, we reserve caution for this finding.     

Effect of CEO power and board strength on bank performance in China

Given that a powerful CEO is more likely to overcome problems and control performance in a firm, this study first focuses on exploring whether CEO power positively affects certain measures of bank performance and which sources of CEO power have these positive impacts. Next, this study further analyzes whether the positive impact of CEO power on performance is negatively mediated by board strength. Our sample includes data on the three main types of Chinese banks for 2006 to –2016.Our results show that CEO structural power significantly improves a bank’s overall profitability, risk-taking ability and lending quality, CEO ownership power significantly raises a bank’s lending quality, and CEO expert power significantly increases a bank’s overall and shareholder profitability. As considering the endogeneity, CEO prestige power significantly improves a bank’s overall profitability. Next, we use the proportion of independent directors as our measure of board strength and find that a stronger board reduces the beneficial effects of CEO structural power on a bank’s lending quality, of CEO ownership power on shareholder profitability, and of CEO expert power on lending quality. There are similar harmful mediating effects when we use the proportion of foreign investors and board size as measures of board strength. Our results can help Chinese bank authorities develop policies to appropriately raise bank CEOs’ power and reduce board supervision of CEO power.     

Market power in CEE banking sectors and the impact of the global financial crisis

The aim of this study is to undertake an up-to-date assessment of market power in Central and Eastern European banking markets and explore how the global financial crisis has affected market power and what has been the impact of foreign ownership. Three main results emerge. First, while there is some convergence in country-level market power during the pre-crisis period, the onset of the global crisis has put an end to this process. Second, bank-level market power appears to vary significantly with respect to ownership characteristics. Third, asset quality and capitalization affect differently the margins in the pre-crisis and the crisis periods. While in the pre-crisis period the impacts are similar for all banks regardless of ownership status, in the crisis period non-performing loans have a negative effect and capitalization a positive effect only for domestically-owned banks.
