Science policy is being challenged. Conceptions of innovation and the nature of research are rapidly being forced beyond traditional views which see innovation as a linear process and science policy in terms of funding issues. Indeed, the policy challenge is being defined by the tension between trying to conduct or encourage research that is at or near an expanding research frontier, while simultaneously functioning within 'steady state' fiscal environments. One key manifestation of this challenge—which is underpinned by a new social contract between the scientific and government communities—is being expressed in terms of the changing role that research instrumentation is playing with regard to research management, research policy and research planning. This paper examines several Candian example f the changing nature of research, with particular reference to the role of instrumentation; it also outlines the particular challenges that small open econmies must face with respect to instrument-intensive research and offers a possible taxonomy for analyzing innovation and policy options.  相似文献

Utterback and Abernathy (1975) developed a dynamic innovation model to explain the patterns of product and process innovation and to show which types of innovation would be most strategically appropriate for firms with particular objectives. In this paper the relation-ships between type and/or source of innovation and a number of firm-characteristic variables are examined. Loglinear regression is employed to determine the extent of the postulated relationships in a set of actual industry data on product innovation. The loglinear model provided results which were highly consistent with predictions made on the basis of previous research into product and process innovation.  相似文献

The Hawaiian archipelago was the last major land area on the planet to be settled, with Polynesians making the long voyage just under a millennium ago. Building on new archaeological and historical research, the lecture provides an overview of the economic and political history of Hawai‘i from the first Polynesian settlements in the thirteen century through U.S. colonisation and statehood. The analysis considers how the political and economic institutions that emerged and evolved in Hawai‘i during its centuries of global isolation changed in response to Hawai‘i's post-1778 integration into a new world of global markets and colonial politics.  相似文献

The purpose of the paper is to propose an original proprietary proxy of a firm's litigation risk. We extend the scope of litigation risk outside of the conflicts with shareholders and the domain of security litigation. We demonstrate that the source of the risk of litigation can be found in the firm's policies and in its management's operational or strategic decisions, even if a sector conditioning effect exists. Based on a sample of 465 US M&A transactions between 2000 and 2014, we provide evidence that the level of litigation risk, at the acquirer's level, has a positive and significant impact on the takeover premium. We also provide evidence that a significant relationship exists between the acquirer's litigation risk and the means of payment. An extension of the sample to international transactions is used as a robustness check; it confirms the previous results.  相似文献

We review some first‐order and higher‐order asymptotic techniques for M‐estimators, and we study their stability in the presence of data contaminations. We show that the estimating function (ψ) and its derivative with respect to the parameter play a central role. We discuss in detail the first‐order Gaussian density approximation, saddlepoint density approximation, saddlepoint test, tail area approximation via the Lugannani–Rice formula and empirical saddlepoint density approximation (a technique related to the empirical likelihood method). For all these asymptotics, we show that a bounded ψ (in the Euclidean norm) and a bounded (e.g. in the Frobenius norm) yield stable inference in the presence of data contamination. We motivate and illustrate our findings by theoretical and numerical examples about the benchmark case of one‐dimensional location model.  相似文献

Corporate Ownership Around the World   总被引:230,自引:0,他引:230  
We use data on ownership structures of large corporations in 27 wealthy economies to identify the ultimate controlling shareholders of these firms. We find that, except in economies with very good shareholder protection, relatively few of these firms are widely held, in contrast to Berle and Means's image of ownership of the modern corporation. Rather, these firms are typically controlled by families or the State. Equity control by financial institutions is far less common. The controlling shareholders typically have power over firms significantly in excess of their cash flow rights, primarily through the use of pyramids and participation in management.  相似文献

The quality of government   总被引:44,自引:0,他引:44  
We investigate empirically the determinants of the quality ofgovernments in a large cross-section of countries. We assessgovernment performance using measures of government intervention,public sector efficiency, public good provision, size of government,and political freedom. We find that countries that are poor,close to the equator, ethnolinguistically heterogeneous, useFrench or socialist laws, or have high proportions of Catholicsof Muslims exhibit inferior government performance. We alsofind that the larger governments tend to be the better performingones. The importance of (reasonably) exogenous historical factorsin explaining the variation in government performance acrosscountries sheds light on the economic, political, and culturaltheories of institutions.  相似文献
