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

A generalization of an inequality on binomial coefficients solved by E. L. Johnson, D. Newman, K. Winston [1] is analyzed
and at the worst the problem is reduced into the choice between two alternatives for the solutions.

This paper examines how the nature of the technological regime governing innovative activities and the structure of demand interact in determining market structure, with specific reference to the pharmaceutical industry. The key question concerns the observation that—despite high degrees of R&D and marketing-intensity—concentration has been consistently low during the whole evolution of the industry. Standard explanations of this phenomenon refer to the random nature of the innovative process, the patterns of imitation, and the fragmented nature of the market into multiple, independent submarkets. We delve deeper into this issue by using an improved version of our previous “history-friendly” model of the evolution of pharmaceuticals. Thus, we explore the way in which changes in the technological regime and/or in the structure of demand may generate or not substantially higher degrees of concentration. The main results are that, while technological regimes remain fundamental determinants of the patterns of innovation, the demand structure plays a crucial role in preventing the emergence of concentration through a partially endogenous process of discovery of new submarkets. However, it is not simply market fragmentation as such that produces this result, but rather the entity of the “prize” that innovators can gain relative to the overall size of the market. Further, the model shows that emerging industry leaders are innovative early entrants in large submarkets. 相似文献

A key question about human societies is how social norms of cooperation are enforced. Subjects who violate norms are often
targeted by their peers for punishment. In an experiment with small teams we examine whether subjects treat punishment itself
as a second-order public good. Results do not support this view and rather suggest a hard-wired taste for punishment; subjects
are engaged in a cooperative task but ignore the public good characteristics of punishment. 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

The transport phase is one of the crucial stages that can be improved to reduce the environmental impact of the fresh fruit and vegetable supply chain. In this paper, we calculate the environmental impact of feasible logistic alternatives for the above-mentioned supply chain so as to identify the type of transportation that incurs the lowest environmental costs. Specifically, we consider the early potato supply chain as a case study, as it involves one of the main fresh vegetables exported from Italy. Consumers' willingness to pay for the environmental impact of different logistic chains was obtained through life cycle assessment. Our results show that rail transport could reduce environmental impact in terms of tons of oil equivalent, environmental loads, and fuel consumption while ensuring reasonable shipment times. Development of an efficient rail transport system would be positively considered by consumers, enhancing their preferences for Italian products. 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

The paper presents a new framework to assess firm level heterogeneity and to study the rate and direction of technical change. Building on the analysis of revealed short‐run production functions by Hildenbrand ( 1981 ), we propose the (normalized) volume of the zonotope composed by vectors‐firms as indicator of inter‐firm heterogeneity. Moreover, the angles that the zonotope's main diagonal form with the axes provide a measure of the rates and directions of productivity change. The proposed framework also accounts for n‐inputs and m‐outputs and, crucially, the measures of heterogeneity and technical change do not require many of the standard assumptions from production theory. 相似文献
