The historic focus of new products research has been on the ability of new products to enhance the profitability and competitive position of the innovating firm. In this article, Timothy Devinney shows that there exists an overlooked and potentially significant side effect associated with new product innovations: financial risk changes. He reports that significant financial risk changes occurred in approximately 50% of the new product announcements he examined. The magnitude of these financial risk changes translates into overestimates or underestimates of the firm's cost of capital by 17% to 18% and is strongly and positively related to the size of the firm and the firm's new product innovation activity.  相似文献

A growing awareness of workplace hazards and identification of airborne contaminants, coupled with a changing safety and health regulatory environment, created an unexpected demand for new and innovative respirators in the early 1980s. 3M's Occupational Health and Environmental Safety Division broke new ground by taking the team concept further than ever before in the company. The division's Action Teams successfully designed, built and introduced products in less than half the time it would have taken previously. Robert Hershock, Charles Cowman and Douglas Peters describe how 3M learned important lessons about team selection, training, performance and motivation, the importance of project sponsors, and the role of middle management.  相似文献

Summary In The Netherlands public debt management is in the hands of the budgetary policy-maker, whose recourse to the capital market can exceed or fall short of the total borrowing requirement in order to absorb or create liquidity. The conduct of that policy since the early 1960's is analyzed in this paper, emphasizing the importance of medium-term control over the public finances as a prerequisite for the ability of debt management to make a flexible contribution to monetary policy. During the 1960's this condition was satisfied and debt management followed a stable countercyclical pattern which, however, was abandoned after the early 1970's as the public finances swung into substantial disequilibrium.The author thanks J. Boughton, L. Bovenberg, D. Hendry, P. Masson, J. Muellbauer, and the referees for comments on earlier versions. However, the views expressed are his alone and do not necessarily represent those of the International Monetary Fund.  相似文献

A subclass of monotonic transferable utility (T.U.) games is studied: average monotonic games. These games are totally balanced. We prove that the core coincides with both the bargaining set à la Davis and Maschler and the bargaining set à la Mas-Colell. To obtain this result a technique based on reduced games is used.
