In this paper, innovation activities of a firm are observed as its R&D spending and participation in three categories of innovation systems. The various factors that can influence a firm's innovation efforts are divided into, (i) firm location reflecting the regional milieu and (ii) firm attributes such as corporate structure, nature of the knowledge production, type of industry and a set of specific firm characteristics. The study is based on information about 2094 individual firms, which may be non-affiliated or belong to a group (multi-firm enterprise). The empirical analysis applies a novel data set to examine the influence of location versus a vector of firm attributes. Among innovative firms, the location of a firm does not influence neither the R&D intensity nor the frequency of interaction in horizontal and vertical innovation systems, when controlling the skill composition, physical capital intensity, industry, firm size and market extension. The paper contributes to the literature by observing that innovative firms have similar characteristics irrespective of where they are located, although the share of innovative firms differs between regions. 相似文献

This paper explores the patterns of citations among patents taken out by inventors in the U.S., the U.K., Francc. Germany and Japan. We find (I) patents assigned to the same firm are more likely to cite each other, and come sooncr than other citations; (2) patents in the same patent class are approxinlatcly 100 titlles as likely to cite each other as ydtents froin different patent classes, but there is not a strong time pattern to this effect; (3) patents whose inventors reside in the same country are typically 30 to 80% more likely to cite each other than inventors from othcr countrics, and these citations come sooner; and (4) there are clear country-specific citation tendencies, e.g., Japanese citations typically come sooner than those of othcr countries. 相似文献

The author argues that the recent controversy over the effect of the minimum wage on employment offers an opportunity for teaching introductory economics. Research findings on the minimum wage could be used to motivate alternative models of the labor market, such as monopsony and search models, and to teach students how economists test hypotheses with data. 相似文献

Textbook authors, in their presentations of aggregate demand–aggregate supply, are admonished to set their houses in order. The writers suggest the continued usefulness of the traditional “Keynesian cross” model as a pedagogical device and present a version that they allege to be superior to the popular AD–AS models found in many contemporary texts. 相似文献

This paper advances a capabilities conception of the individual, and considers some of the problems involved in developing such a conception. It also makes claims about the nature of the capability space as a whole, frames personal development in terms of the idea of moving though the capability space, and argues that people are alike in being increasingly heterogeneous. A key problem for a capabilities conception of the individual is that some capabilities, such as belonging to social groups and having social identities, can undermine individuality. The paper discusses an example in which people can have social identities but can nonetheless be relatively independent when seen as self-organizing. Brief comments on one goal of social economic policy as being identity-promoting conclude the paper. 相似文献
