This paper describes some of the spinoff benefits that can result from R&D projects, and categorizes them in terms of the dimensions of market and technical newness. These dimensions are discussed with reference to two types of spinoffs: 1) alternative market applications, when the results of an R&D project are subsequently applied to a market or use that differs from the originally intended application, and 2) second-generation technologies, when the technology that was the subject of an R&D project is significantly altered or enhanced in unanticipated ways through subsequent R&D. Examples from the Department of Energy's Energy-Related Inventions Program are integrated into the results of literature review to illustrate key concepts, including core technologies, degrees of market and technology newness, technology robustness, and the nature of connections linking spinoffs to prior R&D investments. The paper concludes by discussing spinoffs as a managerial strategy.  相似文献

The “tragedy of the commons” is the familiar problem that open access to a common property resource leads to overexploitation and to zero profits. A commons model is applied to an example of state sponsored private violence, the practice of privateering or licensed piracy. It is predicted that the presence of uncertainty about the value of the prey will reduce the amount of exploitation effort, and that industry profits may be positive due to both uncertainty and heterogeneous exploiters. Using data from England's wars with France and Spain between 1625 and 1630, the model suggests that the commons, represented by enemy merchant shipping, was not overexploited and that privateering profits were positive. The dynamic paths of privateering effort, ships seized, and individual firm profits were, however, consistent with the normal expectation that commons exploitation will peak and fall, as competition drives down returns through entry. “England was never richer than when at war with Spain.” Sir Edward Coke   相似文献

On 26 October 1992, a majority of Canadians in a majority ofprovinces rejected the Charlottetown Accord in a national referendum.The accord capped the "Canada round" of constitutional negotiationsand attempted to satisfy Quebec, while also addressing otherpan-Canadian issues. The accord was defeated for different reasonsin different parts of the country. In Quebec, the "No" sideargued that the agreement did not meet their demands for greaterjurisdictionalautonomy within the federation. In the rest of Canada, the "No"side was particularly successful in demonstrating that the agreementdeviated from the principle of equality in the treatment ofindividuals and provinces. These critiques, inspired by differentvisions of the federation, lead in different directions. Inlight of these divisions, many commentators have suggested thatintergovernmental elites ought to abandon efforts of wholesaleconstitutional change. However, political developments in Quebecmay force these questions back onto the agenda.  相似文献
