A multilevel perspective on the relationship between interpersonal justice and negative feedback‐seeking behaviour

Drawing on social information processing theory, this study uses a multilevel design to integrate the literature on organizational justice with the literature on feedback‐seeking behaviour. Results from a laboratory study with data involving 690 employees showed that individual‐level interpersonal justice was related to employee negative feedback‐seeking behaviour (NFSB) via the mediation of trust in the supervisor. Multilevel analysis of the follow‐up field study with data involving 390 employees from 46 teams confirmed the findings of the laboratory study and indicated that team‐level interpersonal justice was associated with NFSB through a supportive climate. Also, team‐level supervisor support climate was positively related to individual‐level trust in the supervisor. The paper discusses managerial implications of these findings and suggests directions for future research. Copyright © 2014 ASAC. Published by John Wiley & Sons, Ltd.     

管理者认知、开放式创新与企业成长——两职合一的调节作用

基于认知评价理论，通过173家企业中高层管理者有效问卷调查，采用层次回归分析、结构方程模型探讨管理者认知如何影响企业开放式创新与企业成长。结果表明：①管理者对开放式创新的易用性与合法性认知评价，有助于促进企业开放式创新，进而推动企业成长；②管理者感知有用性与感知易用性对企业开放式创新存在替代效应，而管理者感知有用性及易用性与感知合法性存在互补效应，且管理者感知有用性、易用性与合法性对企业开放式创新存在三阶交互效应；③两职合一能够增强管理者感知合法性与企业开放式创新的正相关关系。

A methodology to position nations’ efforts in a technology domain with a patent network analysis: case of the electric vehicle domain

When a nation is making strategies in a technology domain, it makes sense to know where the nation is currently in the domain and to know where other nations are as well. This paper presents a method to position nations’ efforts in a technology domain. The method builds a network of International Patent Classifications (IPCs) based on their co-occurrence in patent applications and applies an index called the Revealed Patent Application Advantage (RPAA), which reflects where nations’ efforts have been spent in a technology domain denoted as the IPC network. We applied the proposed method to position the efforts that have been spent in the electric vehicle (EV) technology domain by mainland China, Germany, Japan, and the United States.

ESTIMATION OF CENSORED PANEL‐DATA MODELS WITH SLOPE HETEROGENEITY

This paper considers estimation of censored panel‐data models with individual‐specific slope heterogeneity. The slope heterogeneity may be random (random slopes model) or related to covariates (correlated random slopes model). Maximum likelihood and censored least‐absolute deviations estimators are proposed for both models. The estimators are simple to implement and, in the case of maximum likelihood, lead to straightforward estimation of partial effects. The rescaled bootstrap suggested by Andrews (Econometrica 2000; 68 : 399–405) is used to deal with the possibility of variance parameters being equal to zero. The methodology is applied to an empirical study of Dutch household portfolio choice, where the outcome variable (portfolio share in safe assets) has corner solutions at zero and one. As predicted by economic theory, there is strong evidence of correlated random slopes for the age profiles, indicating a heterogeneous age profile of portfolio adjustment that varies significantly with other household characteristics.

Inflation Targeting in ASEAN‐10

The paper addresses the empirical question of whether economies that do not systematically target inflation (non‐inflation targeters) experience higher exchange rate volatility as compared with inflation targeters in 10 countries of the Association of Southeast Asian Nation (ASEAN) from 1990 to 2010. The paper examines the role of real exchange rate, exchange rate volatility and the reaction functions of central banks using dynamic panel estimation techniques. The results indicate that the output gap offers more useful information than the inflation gap in setting interest rates for inflation targeters, implying that the real term is more important than the nominal term. In turn, this suggests that an increase in interest rate can be wielded swiftly to reduce real gross domestic product and suppress inflation. The real exchange rate appears as a weaker determinant in setting interest rates for non‐inflation targeters. Inflation targeters experienced lower exchange rate volatility compared with non‐targeters in the ASEAN, which implies that implementation costs to their domestic economies may be marginally lower. Meanwhile, the non‐targeters follow a mixed strategy as both the inflation and real exchange rate are used as instruments to set the interest rates.
