This article attempts to bring coherence to the diversity that characterizes organizational learning research. It argues that
organizational learning is embedded in four schools of thought: an economic school, a managerial school, a developmental school,
and a process school. The article provides a comprehensive analysis of the schools, describes how they differ from each other,
and outlines how each of them can be employed effectively. To demonstrate the benefits of theoretical plurality, the four
schools are applied to the key marketing topics of market orientation and new product development. Implications for future
research in marketing are provided.

The integration of marketing and R&D is a major concern for companies that want to improve their new product performance (NPP). For this integration, companies are using mechanisms such as physical proximity, cross-functional teams, and job rotation. This study examines the effectiveness of these mechanisms by developing a model that distinguishes between indirect effects of mechanisms on NPP (i.e., through a higher level of integration) and direct effects. The model is tested with data collected from 148 pharmaceutical companies. We were able to measure and compare the effectiveness of seven different integration mechanisms, which produced insights that are interesting and relevant for theory as well as practice.
We found that housing marketing and R&D closer to each other and using an influential cross-functional phase review board are the most effective mechanisms to foster integration. Equal remuneration and career opportunities for marketing and R&D and cross-functional teams are somewhat less effective, whereas personnel movement and informal social group events contribute little. ICT appears to be a very effective tool for enhancing NPP. ICT not only fosters integration between marketing and R&D, but it also has an independent direct positive effect on NPP. Through ICT the day-to-day communication between the different parties in the companies becomes much easier, and we think that this fosters the knowledge creation process within marketing and R&D. For cross-functional phase review boards we found a negative direct effect on NPP. Notwithstanding its strong positive effect on integration, a price is paid in terms of NPP. This may be related to the amount of formalization and complexity accompanying this mechanism. 相似文献

This article describes a repeated game of multimarket contact, designed to be played throughout an entire term. Besides enjoying reciprocal advantages in their home markets, firms are perfectly informed after every round about each other's decisions. For most of the game, it appears there is always a future in which to punish deviations, and (with the game's parameters) zero-cost punishments can always be implemented. Thus the game provides all the elements for an escape from the prisoner's dilemma. Theoretical foundations, predictions, and some results are also discussed. 相似文献

Between 1974 and 1988, executives of DuPont, the world's largest producer of CFCs, were confronted with emerging evidence that CFCs were destroying the stratospheric ozone layer. The difficulty that executives face in such cases is that scientific knowledge develops over time and does not necessarily proceed in a straight line toward true conclusions. At the beginning of a new field of research, there is much uncertainty and disagreement among the experts. The solution of the ozone problem required a remarkable cooperation among science, business, and international governments. After looking at the role of DuPont executives in this drama, and the difficulties facing any executive dealing with uncertain science, the paper turns to an evaluation of the field of Business Ethics to see what light it might throw on this and analogous problems. Finally, the paper offers specific suggestions in terms of principles in dealing with uncertain science, and concludes that the course of action that DuPont followed, including some mistakes, can serve as a model for analogous crises. 相似文献

This article considers a linear regression model with some missing observations on the response variable and presents two
estimators of regression coefficients employing the approach of minimum risk estimation. Small disturbance asymptotic properties
of these estimators along with the traditional unbiased estimator are analyzed and conditions, that are easy to check in practice,
for the superiority of one estimator over the other are derived.

Initial margin requirements represent: (1) a cost impediment to the wealth constrained investor and (2) a potential way of mitigating excessive volatility. However, prior empirical research finds that margins are not an effective tool in reducing volatility. We consider the possibility that margins primarily affect certain stocks and investors. Specifically, we test whether margins affect individuals who, as a group, we believe to be the investors most affected when margin requirements change. Our initial empirical tests, however, do not support this contention. 相似文献

Concepts and Indicators of Local Authority Performance: An Evaluation of the Statutory Frameworks in England and Wales 总被引:1,自引:0,他引:1
George A. Boyne 《公共资金与管理》2002,22(2):17-24
A conceptual framework for evaluating statutory performance indicators for local authorities is developed. The framework, which contains 14 dimensions of organizational performance, is then applied to the indicators set for local government from 1993/94 to 2001/02. The results show that the validity and comparability of the indicators has improved substantially over time. However, a critical weakness that remains is the absence of indicators that link spending with service outcomes. Such indicators are essential if judgements about value for money and Best Value are to be made. 相似文献

Finance theory proposes that firms' cost of capital increases when market makers set wider spreads due to perceived higher information asymmetry across traders. Using a sample of UK investment property firms and controlling for firms' non-random selection of external monitors, we find evidence that market makers perceive information asymmetry across traders to be lower for firms employing external appraisers versus those employing internal appraisers. This evidence is consistent with liquidity-motivated traders being unable to overcome such reliability differences using asset value information from sources other than accounting. We fail to find a similar difference for firms employing Big 6 versus non-Big 6 auditors. Our findings contribute to the debate over the recognition of fair value estimates for long-lived tangible assets by documenting that reliability differences attributable to differential monitoring by appraisers can affect information asymmetry, and therefore firms' cost of capital. 相似文献

This paper examines Britain's long run growth and productivity performance since the late nineteenth century, taking an international comparative perspective and disaggregating by sector. Britain was richer than the United States and Germany in 1870 largely because of high levels of labour productivity in services and agriculture rather than in industry, together with a highly favourable structure, particularly a small share of the labour force in agriculture. By 1990, the productivity gap in manufacturing had not grown bigger. Rather, the deterioration in Britain's overall comparative labour productivity position has been concentrated in services and agriculture, together with the effects of structural change, particularly the later shift of labour out of agriculture in the United States and Germany. 相似文献
