This paper analyzes the effect of public R&D subsidies on firms' private R&D investment per employee and new product sales in German manufacturing. Parametric and semiparametric two‐step selection models are applied to this evaluation problem. The results show that the average treatment effect on the treated firms' R&D intensity is positive. The estimated effects are robust with respect to the different selection models. Further results show that publicly induced R&D spending is as productive as private R&D investment in generating new product sales. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

The findings of a survey of 22 prominent US futures studies published between 1967 and 1982 are presented. Common themes and divergences among the studies are delineated, and the underlying reasons for these are discussed, in order to throw some light on the strengths and limitations of futures studies as a whole.  相似文献

Changes in content and presentation styles of TV news are an indicator of the way the public today perceives the political process. ?Tabloidization‘, i. e. an adoption of presentation styles used by tabloid newspapers and magazines, has been introduced as an operational concept to measure these changes. In order to assess whether a long-term process of tabloidization occurred in German TV news, we content-analyzed the political coverage in the main news broadcasts of the four major TV channels four weeks before the German general elections in 1983, 1990, and 1998. The empirical basis of this analysis is 1,241 reports. We found strong tendencies towards tabloidization. They have occurred on all dimensions we investigated, i. e. in content (decrease of policy coverage), form (e. g. more personalization), and style (e. g. shorter sequences). As could be expected, indicators of tabloidization are generally stronger for the commercial than the public TV stations. However, one of the public stations (ZDF) has also shown a sharp increase of tabloidization features, in some cases even surpassing its two commercial competitors.  相似文献

The design of written promotional material and branding strategies in insurance companies — an exploratory study As a result of numerous changes the insurance market is facing — the realisation of the single European market and modified legal regulations to name but a few - the branding of insurance products is gaining relative importance. The objective of this paper was to examine the branding strategies employed by selected Austrian insurance companies on the one hand as well as to give an overview of the design of written promotion material on the other hand. This was achieved by using content analysis as the method of choice as well as by testing four hypotheses. In total, six single-line and ten multi-line insurance companies were analyzed. The analysis was limited to enterprises operating in Austria.  相似文献

Several authors have recently interpreted the European Central Bank's (ECB's) two-pillar framework as separate approaches to forecast and analyse inflation at different time horizons or frequency bands. The ECB has publicly supported this understanding of the framework. This paper presents further evidence on the behaviour of euro area inflation using band spectrum regressions, which allow for a natural definition of the short and long run in terms of specific frequency bands, and causality tests in the frequency domain. The main finding is that variations in inflation are well explained by low-frequency movements of money and real output growth and high-frequency fluctuations of the output gap.  相似文献

Although the Common Agricultural Policy of the European Union has broadened its objectives to integrate social issues, several hard-to-reach groups of farmers and workers continue to be ignored by advisory services and associated policies. Connecting with these groups has a strong potential to increase the economic and social cohesion of European agricultures. We interviewed over 1,000 farmers across Europe and identified features of these groups that are often overlooked by advisory services. We critically reflected on the social cohorts omitted from advisory services and how they could be better reached; they include farm labourers, new entrants or ‘career changers’, and later adopters. We clarify the different types of advisors in the advisory landscape, distinguishing between those who are linked to or independent from sales of inputs or technologies. We make concrete recommendations about how to engage advisors with hard-to-reach groups, with approaches suited to different national contexts of Agricultural Knowledge and Innovation Systems (AKIS); thus contributing to the ‘AKIS dimension of National Strategic Plans of the next Common Agricultural Policy, 2023–2027. We argue for the more effective use of advances in the social sciences through a better understanding of advice as social interaction which can bolster the inclusiveness of public policies.  相似文献

Global virtual teams are faced with the challenge of developing trust in a technology‐mediated context to overcome anxiety and uncertainty in their interactions. Research shows that adjustment is a function of an individual's ability to manage his or her anxiety and uncertainty in an unknown context (Gudykunst, 1995). We propose that the type of cross‐cultural training (CCT) received can influence cognitive adjustment in global virtual teams. Building on phenomenology and sense‐making theory, we argue that training needs to develop global virtual team members' capabilities in dealing with the unknown rather than providing ready‐made concepts of cultures. Managerial implications of our theoretical discussion of cognitive adjustment and how CCT influences it are discussed, as are directions for future research. © 2009 Wiley Periodicals, Inc.  相似文献
