Many studies examine firm private knowledge, but purport to be generalizable to the totality of firm knowledge, both public and private. This study demonstrates that public and private firm knowledge are empirically separable constructs that have significant and yet different influences on innovative outcomes. The example of product development effectiveness within this study shows that both public and private knowledge are significantly related to product development quality; however, public knowledge is negatively related to quality lapses while private knowledge is positively related to quality lapses.

美国钢铁贸易保护争端及其对世界经济贸易的影响 总被引:3,自引:0,他引:3
美国钢铁保障措施的出台是经济衰退期外贸政策保护主义倾向进一步加强的具体表现。作为WTO成员,美国按国内法201条款实施的钢铁保障措施必须符合WTO保障措施规则。但美国钢铁保障措施即使符合WTO规则,也是通过损害其钢铁贸易伙伴正当利益来追求本国利益最大化。因此,在全球贸易体制约束下,美国的行为必然引起各相关方与美国之间运用全球贸易规则的利益博弈,并由此对世界经济贸易产生重大影响。 相似文献

In this paper, we provide a model for diffusion of products, which are available in limited quantity until a known expiration date, after which the unsold products have no value. We consider the case of a performing arts company. The model development is built on the foundation of classical product diffusion model by Bass (1969) and the psychological effect known as the scarcity principle (Cialdini, 1985). Our empirical analysis results show that the proposed model can provide significant improvement in prediction of the products characterized by the scarcity effect. 相似文献

This paper looks at real exchange rate behavior by focusing on three OECD economies (Australia, Canada, and New Zealand) where primary commodities constitute a significant share of their exports. For Australia and New Zealand especially, we find that the US dollar price of their commodity exports (generally exogenous to these small economies) has a strong and stable influence on their floating real rates, with the magnitude of the effects consistent with predictions of standard theoretical models. However, after controlling for commodity price shocks, there is still a purchasing power parity puzzle in the residual. The results here are relevant to developing commodity-exporting countries as they liberalize their capital markets and move towards floating exchange rates. 相似文献

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.

We use a vertical product differentiation model under partial market coverage to study the social welfare optimum and duopoly equilibrium when convex costs of quality provision are either fixed or variable in terms of production. We show the following new results. First, under fixed costs, the social planner charges a uniform price for the single variant that just covers costs of quality provision. Like the duopoly equilibrium, this socially optimal pricing entails a partially uncovered market, but a smaller share of the market is served compared with the duopoly equilibrium. Second, for the variable cost case, it is socially optimal to provide both high‐ and low‐quality variants, but market shares need not be equal. This differs from the result in fully covered markets. Third, in the duopoly equilibrium, the quality spread is too wide under variable costs relative to the social optimum. Under fixed costs, the duopoly produces two variants, but quality is too low relative to the social optimum, which has only one variant. 相似文献

林产品市场模型文献综述 总被引:1,自引:0,他引:1
关于林产品市场的数量研究开始于上个世纪50年代。早期的研究主要以时间序列数据为主。近几十年来,由于经济理论在林产品市场模型中的应用,模型估计方法的改进,以及详细数据的获得,林产品市场模型越来越完善。文章对近几十年来出现的主要建模方法,及其应用作一回顾,并对这些方法的优缺点作简单的比较。 相似文献
