Leader-member exchange as a linking pin in the idiosyncratic deals - Performance relationship in workgroups

In the current investigation, idiosyncratic deals (i-deals; individualized work arrangements) are modeled as differentiated resources that shape leader-member exchange (LMX) relationships in workgroups. We integrate literature on leader-member exchange (LMX) with research on i-deals to argue that employee evaluations of i-deals received from the grantor –typically the leader- enhance employee perceptions of LMX, which in turn become instrumental in generating positive performance outcomes. Furthermore, because workgroup characteristics have potential implications on the relationship between a deal grantor and the deal recipient, drawing upon social identity theory of leadership, we reason that the i-deals-LMX relationship is affected by the overall value congruence among the group members. Cross-level moderated mediation analyses on multi source data obtained from 289 employees nested in 60 workgroups showed that the mediational role of LMX in the i-deals to performance outcomes relationship was weaker in high value congruence groups.     

Inferences for a Partially Varying Coefficient Model With Endogenous Regressors

In this article, we propose a new class of semiparametric instrumental variable models with partially varying coefficients, in which the structural function has a partially linear form and the impact of endogenous structural variables can vary over different levels of some exogenous variables. We propose a three-step estimation procedure to estimate both functional and constant coefficients. The consistency and asymptotic normality of these proposed estimators are established. Moreover, a generalized F-test is developed to test whether the functional coefficients are of particular parametric forms with some underlying economic intuitions, and furthermore, the limiting distribution of the proposed generalized F-test statistic under the null hypothesis is established. Finally, we illustrate the finite sample performance of our approach with simulations and two real data examples in economics.     

电子商务环境下税收中的法律问题分析

电子商务的发展使传统税收理论概念模糊不清,从而造成税负不公、税源监控和税收稽查困难以及国际避税增多等现状,而中国的电子商务征税除了以上问题外,大陆与港澳台地区税法及税收管辖权冲突也日益凸显。因此,中国应完善现有税法体系,积极研究制定有关电子商务税收的法律法规:确立科学的税收征管模式,强化税务稽查及确立税收评估制度等。同时采取加强国际税务协助特别是与港澳台地区的合作等措施,以有效解决电子商务环境下的税收问题。

弱势群体的心理困境及消解策略

弱势群体的心理,多呈消极负面等特点。弱势群体具有较为严重的相对剥夺感、较为强烈的受挫情绪,并表现出一定程度的反社会倾向。这无论是对社会的稳定,还是对他们自身的发展都极为不利。弱势群体心理困境的消解,主要通过认知重建策略和合理归因策略来实现。

在地贸易统计还是属权贸易统计？——FDI对传统贸易统计的颠覆及其对策

一、传统贸易统计平衡对全球化条件下国际交易当事方利得的背离(一)现行国际贸易统计制度的基石和特征现行国际贸易统计制度定型于二战后初期。以联合国《国民核算体系》(SNA)、国际货币基金组织(IMF)制订的《国际收支手册》①和《国际贸易统计的概念与定义》为其基石。前两者都采用“在地”(residence)原则,将参与交易的个人和机构区分为一个经济体的居民(residents)和非居民(non residents),只有居民与非居民之间的交易才记入国际收支而后者规定贸易的跨境标准,其内涵是一致的,都是把跨境贸易(cross bordertrade)等同于国际贸易。对于…
