Close relationship with the supervisor may impede employee creativity by suppressing vertical task conflict

Leader‐member exchange as a form of supportive leadership is expected to foster employee creativity. However, empirical evidence suggested this relationship is complex. This study attempts to address this complexity by proposing and testing a curvilinear mechanism, which attenuates the overall positive effect of LMX on creativity by transmitting a curvilinear indirect effect via vertical task conflict. Results drawn from a sample of 276 supervisor–subordinate dyads provided support for the hypothesized curvilinear indirect effect. Specifically, LMX was found to negatively influence employee creativity by suppressing vertical task conflict for subordinates in high‐quality LMX relationships, while the indirect effect was not significant for subordinates in low‐quality LMX relationships.     

Asymmetric effects of industrial production,money supply and exchange rate changes on stock returns in Turkey

The aim of this article is twofold: First, it examines the asymmetric effects of industrial production, money supply and RER on stock returns in Turkey by using the non-linear autoregressive distributed lag (NARDL) model over the periods of 1994:01–2017:05 and 2002:01–2017:05. Second, it tries to determine whether there is a change of these macroeconomic variables’ effects on stock returns after the 2001 financial crisis since after 2002 period represents a structural break from the past in terms of economic, political and macroeconomic policy approaches. The study finds that the effects of the changes in industrial production, money supply and RER on stock returns are asymmetric, and the asymmetries are larger after the 2002 subsample compared to the full sample period. The empirical results further suggest that tight monetary policies appear to retard the stock returns more than easy monetary policies that stimulate them.     

Farsighted strategies in the formation of a communication network

I examine the formation of a specific communication network, a variant of the two-way flow model, in which agents have farsighted strategies. I show that the likelihood to form efficient networks tends to zero for sufficiently large network sizes.

浙江省南部山区生态系统服务价值评估

选择浙江省南部山区泰顺县作为研究区域,对全县各类生态系统服务价值进行了定量评估,并在此基础上进行了生态系统服务重要性及其区域分异规律的综合评价。结果表明:2012年全县生态系统服务总价值为334.1×108元,是当年该县GDP的6.40倍,其中以水源涵养、气候调节、土壤保持服务价值为主,三者分别占总价值的62.35%、21.8%、7.16%,生态系统有着巨大的间接服务价值。生态系统服务重要性分析结果显示,极重要、很重要、重要区、一般重要区域分别占全县总面积的31.43%、34.57%、20.35%、13.64%,评估结果可为生态系统的科学管理、生态保护关键区的确定以及生态保护和建设政策的制订提供理论依据。     

Are you really doing good things in your boss's eyes? Interactive effects of employee innovative work behavior and leader–member exchange on supervisory performance ratings

Organizations increasingly depend on employee efforts to innovate. However, the quality of relationships between leaders and employees may affect the recognition that employees receive for their innovative work behaviors. Drawing from a social cognition perspective, we tested a model in which leader–member exchange (LMX) moderates the impact of employee innovative work behavior on supervisory ratings of employee performance. Results from two multisource studies combining self, colleague, and supervisor ratings consistently showed that employees receive more favorable performance ratings by engaging in innovative work behavior when they have high‐quality LMX relationships. Moreover, we found that this interactive relationship was mediated by leader perceptions of innovative employee efforts, providing support for a moderated mediation model. Implications for the literatures on performance appraisal, LMX, and innovation are discussed.

Total Factor Productivity Growth in U.S. Commercial Banking for 1935–1991: A Latent Variable Approach Using the Kalman Filter

This paper studies total factor productivity (TFP) in U.S. commercial banking for 1935–1991. TFP can contain a procyclical bias when some input factors are not freely variable, causing their shadow and market prices to differ. We correct this bias in TFP by decomposing it into its latent stochastic trend and cyclical components by employing the Kalman filter. Using the FDIC's annual aggregate data on U.S. insured commercial banks, we report that the stochastic trend has been positive during 1935–1991, with an average annual growth rate of 2.27%, and that it exhibits a decaying time path. We attribute the positive TFP growth to technical change.     

产权、金融稳定政策与中央银行独立性

This paper builds a micro-behavior model of central bank and financial institutions from the perspective of property-rights. By analyzing the theoretical model and the practice, we conclude that, in the framework of the present financial stabilization policies in China, the central bank’s functions of monetary policy and financial stabilization are enslaved to financial institutions. Thus, central bank independence has been damaged because of the actual property-right relation between the central bank and the financial institutions. The policy implication is to cut off the property-right relation between the central bank and the financial institutions. __________ Translated from Caijing wenti yanjiu 财经问题研究 (Research on Finanical and Economic Issues), 2007, (6): 3–9
