Evolutionary Stability in the Investment-Opportunism-Retaliation Game

Can economically efficient outcomes be obtained and sustained in the absence of externally enforced property rights? We study the evolutionary properties of a game that exhibits two well-defined Nash equilibria: one generates an inefficient outcome while the other set generates an efficient outcome supported by the potential for retaliation. Although standard forward-looking refinements eliminate the efficient equilibrium, neither equilibrium type satisfies strict evolutionary stability criteria. However, both types of equilibrium define strategies that are neutrally stable, which makes them vulnerable to drift in dynamic environments. We conduct computer simulation experiments in which players learn adaptively via a tournament selection mechanism called sophisticated experimentation. Our simulations demonstrate that while the system spends a disproportionately high proportion of time in the inefficient equilibrium set, the efficient equilibrium is pervasive as the system drifts back and forth between the equilibrium sets, never settling on one or the other.     

Learning across the life cycle: Experimentation and performance among the hollywood studio heads

Guided by notions from the literature on organizational learning, this paper investigates how product line experimentation and organizational performance change across the careers of top managers. Its subjects are the studio heads who ran all the major Hollywood film studios from 1936 to 1965. The study found first, that product line experimentation declines over the course of executive tenures; second, that there is an inverse U‐shaped relationship between top executive tenure and an organization's financial performance; and third, that product line experimentation is more likely to benefit financial performance late in top executives' tenures. These findings are consistent with a three‐stage ‘executive life cycle’. During the early years of their tenures, top managers experiment intensively with their product lines to learn about their business; later on their accumulated knowledge allows them to reduce experimentation and increase performance; finally, in their last years, executives reduce experimentation still further, and performance declines.

我国生物能源产业的发展前景与对策

生物能源产业是一个正在兴起并富有巨大前途的新型产业。发展生物能源产业有利于解决能源危机，有利于环境保护，有利于促进农村经济的发展。与国外相比，我国生物能源产业的发展还相对比较落后，为加快我国生物能源产业的发展，应尽快制定生物能源产业发展的产业政策，加大对生物质能产业的扶持力度，加强生物质能开发研究。     

企业生态群落和“大”动态能力战略观

战略管理的核心作用是把环境的机会和企业的力量相匹配，同时保护企业的弱点使之不受环境的威胁。目前的企业能力理论过多地把其战略目光放在了企业内部。然而，竞争日益全球化的今天，企业的竞争，其实质不再仅仅是单纯意义上的企业能力与企业能力的较量，而是企业所属的生态群落能力间的较量。为此，本文从全球化竞争的视角出发，阐释了企业生态群落中政府动态能力、企业动态能力、金融制度动态能力、教育制度动态能力的内涵，探讨了政府动态能力、企业动态能力、金融制度动态能力、教育制度动态能力间互动作用机理，在此基础上提出了“大”动态能力企业战略观。
