A stage-dependent model of resource utilization,strategic flexibility,and implications for performance over time: Empirical evidence from a transitional environment

It has long been recognized that there is a tradeoff between exploration and exploitation. How organizations utilize resources across time and space will affect firm survival and growth. In this paper, we examine resource utilization and performance implications over time in an environment undergoing fundamental institutional transformation. Based on a large archive of Chinese government data from 1988, 1992, and 1996, the study finds that (1) the impact of resource utilization is contingent on the degree to which different resources are committed to factors of production, (2) the impact is curvilinear and only valid within an “optimal” range, and (3) the performance implications change over time. As firms enter later stages of the transitional process, efficiency becomes less important as they shift their strategic focus from exploitation to exploration, which requires more flexibility. These findings have significant bearing on the issue of upgrading technological competitiveness in China as the country becomes increasingly integrated in the global economy. Such insights may also have implications for other emerging economies in Asia.

Do ongoing networks block out new friends? Reconciling the embeddedness constraint dilemma on new alliance partner addition

Research Summary: This study addresses a theoretical dilemma regarding how alliance network constraint (reflected by network cohesion) affects a firm’s alliance formation with new partners. Using a network pluralism approach, we separate a firm’s ego alliance network into two activity‐based networks—an exploratory network and an exploitative network—based on the primary value chain activity involved in each alliance. We argue that the cohesion of exploratory or exploitative networks has an inverted U‐shaped effect on the addition of new partners in the same activity‐based network, and a positive effect on the addition of new partners in the other network. Results based on data from the biotechnology industry largely support our predictions with one exception. Our study contributes to both scholarly understanding of network embeddedness and alliance practice. Managerial Summary: The structure of firms’ ongoing alliance networks may have paradoxical implications for their efforts to search for and form alliance with new partners. That is, when a firm’s alliance partners are tightly connected with each other, the cohesive network tends to both encourage and impede the focal firm to add new partners. We resolve this dilemma by showing that when a firm is deeply entrenched in a cohesive alliance network conducting a certain type of activities (e.g., R&D activities), it may not easily add new R&D alliance partners. However, it may still be able to escape from the cohesive R&D alliance network by seeking new partners conducting other activities (e.g., manufacturing activities).     

团队氛围、董事会内部沟通与战略绩效

本文在理论分析的基础上提出研究假设,通过问卷调查的方式搜集数据,以47家企业董事会454份有效问卷为样本进行实证研究,结果表明,团队氛围中的团队信任对董事会内部沟通具有显著的正向影响;团队氛围中的情感冲突对董事会内部沟通具有显著的负向影响;董事会内部沟通对企业战略绩效中的团队学习力、决策有效性和战略一致性均具有显著的正向影响。研究不仅丰富了董事会团队过程理论,而且能够有效地指导公司治理实践。

Competition,Prices and Quality in the Market for Physician Consultations

Prices for consultations with General Practitioners (GP's) in Australia are unregulated, and patients pay the difference between the price set by the GP and a fixed reimbursement from the national tax‐funded Medicare insurance scheme. We construct a Vickrey‐Salop model of GP price and quality competition and test its predictions using individual GP‐level data on prices, the proportion of patients who are charged no out‐of‐pocket fee, average consultation length, and characteristics of the GP's, their practices and their local areas. We measure the competition to which the GP is exposed by the distance to other GP practices and allow for the endogeneity of GP location decisions with measures of area characteristics and area fixed‐effects. Within areas, GP's with more distant competitors charge higher prices and a smaller proportion of their patients make no out‐of‐pocket payment. GP's with more distant competitors also have shorter consultations, though the effect is small and statistically insignificant.
