An empirical examination of vacillation theory

Research summary : Since Nickerson and Zenger (2002) proposed how vacillation may lead to organizational ambidexterity, large‐sample empirical tests of their theory have been missing. In this paper, we empirically examine the performance implications of vacillation. Building upon vacillation theory, we predict that the frequency and scale of vacillation will have inverted U‐shaped relationships with firm performance. We test our hypotheses using patent‐based measures of exploration and exploitation in the context of technological innovation and knowledge search. Managerial summary : Firms often shift their focus on technological innovation and knowledge search from seeking new and novel knowledge (i.e., exploration) to extending and refining existing knowledge (i.e., exploitation) or vice versa. We examine how the frequency and scale of firms vacillating between exploration and exploitation may affect their performance. We find that both too infrequent or too frequent changes and a too small or too large scale of changes are not desirable. Copyright © 2016 John Wiley & Sons, Ltd.     

突发性地质灾害的防治与应对

随着人类对自然的深入开发,破坏自然生态平衡的行为越演越烈。自然生态平衡遭到严重破坏,人为诱发的地质灾害发生越来越频繁。山体崩塌、滑坡、泥石流等突发性地质灾害造成的人员伤亡和经济损失逐年增长。探讨如何防止与应对突发性地质灾害具有很强的现实意义。

Measuring total factor productivity,technical change and the rate of returns to research and development

This paper examines the relationship between research and development expenditures and total factor productivity using establishment level (or micro) data. The confidential data are taken from the U.S. Bureau of the Census Annual Survey of Manufacturers and other Census surveys. Several measures of total factor productivity are considered as are several variables that proxy for technical knowledge. The latter include research and development expenditures by the firm, the accumulated research expenditures of the industry, and new equipment purchases. We find that there is a statistically significant relationship among above measures of technical expertise and a broad measure of total factor productivity.The refereeing process of this paper was handled through N.R.

Corporate social responsibility and strategic trade policy: An endogenous timing game and its policy implications

This study incorporates the corporate social responsibility (CSR) initiatives of a domestic firm and analyses strategic trade policy towards a foreign firm in a different market structure. We show that the tariff rate under a foreign (domestic) firm's leadership is lowest when the degree of CSR is large (small). We also show that the foreign firm's leadership yields the highest welfare when the degree of CSR is intermediate, while the domestic firm's leadership yields the highest welfare otherwise. In an endogenous‐timing game, we show that a simultaneous‐move outcome is the unique equilibrium when the degree of CSR is small; thus, it is never socially desirable. We also show that the domestic firm's leadership can be an equilibrium, which results in the highest welfare when the degree of CSR is large. Finally, when the degree of CSR is large, collusive behaviours between the domestic and foreign firms can increase welfare.
