We discuss the strengths and weaknesses of five alternative innovation indicators: R&D, patent applications, total innovation expenditure and shares in sales taken by imitative and by innovative products as they were measured in the 1992 Community Innovation Survey (CIS) in the Netherlands. We conclude that the two most commonly used indicators (R&D and patent applications) have more (and more severe) weaknesses than is often assumed. Moreover, our factor analysis suggests that there is little correlation between the various indicators. This underlines the empirical relevance of various sources of bias of innovation indicators as discussed in this paper. 相似文献

Scholars in our field, Operations and Supply Chain Management (OSCM), are under high pressure to show research productivity. At most schools, this productivity is measured by the number of journal articles published. One possible response to such pressure is to improve research efficiency: publishing more journal articles from each data collection effort. In other words, using one dataset for multiple publications. As long as each publication makes a sufficient contribution, and authors ensure transparency in methods and consistency across publications, generating more than one publication from one data collection effort is possible. The aim of this Notes and Debates article, however, is to draw attention to inappropriate reuse of empirical data in OSCM research, to explain its implications and to suggest ways in which to promote research quality and integrity. Based on two cases of extensive data reuse in OSCM, eighteen problematic practices associated with the reuse of data across multiple journal articles are identified. Recommendations on this issue of data reuse are provided for authors, reviewers, editors and readers. 相似文献

Vertical specialization (VS) is quantified by the VS share, which measures the average import content per dollar of exports. A characteristic of China’s export trade is its strong dependence on assembly and processing activities. To take proper account of this, China’s VS shares should explicitly distinguish processing export production from other production. We estimate China’s annual VS shares from 2000 to 2012—the latest year for which a special input–output table is available that makes such an explicit distinction. We find that VS shares increased from 2000 to 2004 and subsequently started to decrease. To explore why it has declined, we introduce a new structural decomposition approach. We find that the decrease of the VS share appears to have been driven mainly by the substitution of imported intermediates by domestic products. This occurred in particular in the production of exports, which implies an upgrading of China’s position in global value chains. 相似文献

Many companies experience difficult situations as a result of their selected strategy. Strategic management theories implicitly assume that companies have a free choice in setting their strategy. Hence, when companies experience difficult situations this is because of management inadequacy. It is questionable whether companies always have a free choice. This research examines this issue by examining the new product strategies of the two main competitors in the commercial aircraft industry. The development of the A380 aircraft was selected to determine to what extent the companies had a choice in setting their product development strategies. The conclusion is that neither has the alleged freedom for setting its strategy. Implications of this finding are that the strategy theory needs to be adjusted for this choice issue, and that management should not always be held fully responsible for the developing events. 相似文献

This paper presents an overview of issues for future research. as identified by the papers appearing in the Special Issue on Innovation in Telecommunications. To this end. we elaborate upon the emergence of a new innovation regime in telecommunications, discuss the performance and sustainability of this new innovation regime, and reflect upon institutional choices for the regime and accompanying policy options. Further research on innovation in telecommunications is advocated, taking up a broad range of issues, including long-term industrial evolution and sustainability concerns in a wide sense. 相似文献

McMillan's (1995) ‘flexibility’ proposition suggests a testable hypothesis about beauty contests spectrum assignments. Such flexibility purportedly allows regulators to pursue social welfare (network deployment) goals. A separate argument is that more competitive beauty contests enhance the probability of assignment. The study concludes that regulators do indeed focus on societal (network deployment) welfare goals. Initially, consideration is given in the immediate term where licenses are awarded based on operator aftermarket commitments. Subsequently, spectrum package attributes and financial performance obligations, specified in the tender documents, come into play to support the networks spread more widely through the population in a timely manner. Finally, the econometric results suggest that more competitive beauty contests enhance the probability of assignment. 相似文献

Since the 1970s technology assessment by public bodies has become generally accepted as necessary. Modes of technology assessment differ from country to country, in terms of degree of institutionalization, acceptance by policy makers and level of public involvement, and these in turn depend on the goals, methods and organizational framework of the particular technology assessment. The varying social and political roles of technology assessment arise out of national political traditions and differing cultural views of technology. This article compares modes of biotechnology assessment in the USA, Japan and Denmark, focusing on the role of public discussion in the policy-making process. By analysing these three different contexts, the article seeks to uncover ways in which the cultural conditioning of technology policy takes place. 相似文献

In this article, we forecast employment growth for Germany with data for the period from November 2008 to November 2015. Hutter and Weber (2015) introduced an innovative unemployment indicator and evaluated the performance of several leading indicators, including the Ifo Employment Barometer (IEB), to predict unemployment changes. Since the IEB focuses on employment growth instead of unemployment developments, we mirror the study by Hutter and Weber (2015). It turns out that in our case, and in contrast to their article, the IEB outperforms their newly developed indicator. Additionally, consumers’ unemployment expectations and hard data such as new orders exhibit a high forecasting accuracy. 相似文献

In this article, we analyze the political choice of the extent and means of income redistribution between high and low-skilled
workers. Redistributive tools encompass both fiscal transfers (a negative income tax) and a minimum wage requirement. We assume
the use of fiscal instruments alone to be the first-best means of redistribution. We show that high-skilled workers may favor
a second-best, minimum wage requirement because it increases unemployment, hence raising the marginal cost of redistribution,
and creates a justification for them to moderate low-skilled workers’ claim for redistribution.
