With a study of three Dutch newspaper organisations, we identify four dimensions along which incumbent response to discontinuous change may differ: response timing (early or late), size of commitment to the new business (big or small), progression of commitment to the new business (continuous or intermittent), and approaches to bridging the capability gap (internal development, strategic alliance, or acquisition). These response strategies are neither mutually exclusive nor static, and their relative focus differs over time as well as across incumbents. Such inter-temporal and cross-sectional variations in response strategies are influenced by various incumbent-specific characteristics and shaped by interrelated contingencies internal or external to incumbents.  相似文献

This paper investigates to what extent the substantial increase in exposures of local European equity market returns to global shocks is mainly due to a convergence in cash flows (“economic integration”), to a convergence in discount rates (“financial integration”), or to both. We find that this increased exposure is nearly entirely due to increasing discount-rate betas. This finding is robust to alternative ways of calculating discount-rate and cash-flow shocks.  相似文献

Convergence in a Two-Sector Nonscale Growth Model   总被引:2,自引:0,他引:2  
Much of the convergence debate has focused solely on output. Recent empirical evidence suggests that crucial inputs, such as technology and capital, may exhibit markedly distinct convergence patterns. We examine the convergence characteristics of a two-sector nonscale model of growth that features population growth and endogenous technology. The model replicates key economic ratios and speeds of convergence with relative ease. Most important, however, is that capital and technology differ strikingly in their convergence paths and speeds. The nonconstancy of the convergence rates and the nonproportionality of the endogenous variables during transition suggests further refinements for the empirical tests of convergence.  相似文献

In the contemporary ICT environment, we are confronted with a growing number of failing innovations. New technological innovations often fail because too much attention is still given to (technical) product-related features without taking into account the most important parameters of user acceptance. In addition, suppliers of ICT products often lack accurate insight into the distinguished profiles of their (potential) target audience. In this article theoretical considerations and empirical results on this matter are highlighted. First of all, an approach is proposed in which more traditional and often scattered vision(s) on adoption determinants are broadened into an integrated framework. The approach provides a stronger base for better targeting of (new) users of technologies. Secondly, the authors elaborate on this by rethinking these determinants with regard to later adopters. Later adopters (or even non-adopters/users) are often ignored in technology acceptance research. However, especially for policy purposes, the understanding of why people do not adopt or do not use ICT is strongly relevant in the light of the development of an inclusive information society. Both approaches are illustrated by case studies starting from a common list of nineteen ICT appropriation determinants. This framework enables to better profile both earlier and later adopters as well as it allows to formulate recommendations how to bring innovations in the market. Summarizing, this contribution offers an integrated approach on technology acceptance research by bridging the gap between a market and a policy-oriented point of view.  相似文献

This special issue includes five of the best papers presented at the 20th IPSERA conference. This conference was organized by Maastricht University and took place in Maastricht, The Netherlands. The conference theme was: ‘Vision 20/20: Preparing today for tomorrow's challenges’. In this editorial we discuss the future challenges in Purchasing and Supply Management and how one can prepare for these today. We make use of the concept of weak signals to detect a number of emerging future trends. All abstracts of the 110 conference papers were analysed using text mining and tag clouds. Also we introduce the five papers that were selected by the conference reviewers and track chairs as the best papers of the conference.  相似文献

Professional development plans (PDPs) have recently been introduced in Dutch schools to support teachers' professional development. However, teachers' beliefs regarding the use of PDPs have not been systematically researched, whereas research on the use of PDPs indicates that the implementation is not always successful and depends on how use is perceived by users. Some teachers may doubt the usefulness and purpose of a PDP, and this might influence their reactions to its introduction. Using Fishbein and Ajzen's theory of planned behaviour, the current study explored teachers' characteristics (such as age and years of experience in education) and their beliefs about intention to use a PDP. Clusters of teachers with similar characteristics and beliefs were identified to permit the design of interventions specific to each cluster. Semi‐structured interviews were conducted to reveal these beliefs and characteristics for a sample of 41 teachers working in schools where using a PDP was mandatory. The results showed that most teachers had a positive attitude towards using a PDP. However, because using a PDP was mandatory, they felt pressured to produce one. Moreover, it was not a priority. This was because of their high workload. The present study contributes to the literature by adding knowledge of teachers' beliefs about the use of PDPs. This knowledge may help the PDP to become a more effective device in promoting teachers' professional development.  相似文献

This article focuses on similarities and differences in the perception of companies in the United States (7 cases in New York State) and Europe (5 cases from Belgium) on global purchasing opportunities and on how they react to these. It addresses two questions. First, what forces drive companies to engage in international purchasing? Seemingly basic issues such as price, quality and availability appear to be the three most important elements in this respect. Second, how do organisations organise for international purchasing in terms of configuration of actors and activities and their use of intermediaries such as brokers or agents? Findings indicate that the ways companies are organised run parallel on both sides of the Atlantic. However, we find that the New York State cases rely much more on intermediaries for their international purchasing activities than Belgian companies do.  相似文献

Bekaert et al. (2005) define contagion as “correlation over and above what one would expect from economic fundamentals”. Based on a two-factor asset pricing specification to model fundamentally-driven linkages between markets, they define contagion as correlation among the model residuals, and develop a corresponding test procedure. In this paper, we investigate to what extent conclusions from this contagion test depend upon the specification of the time-varying factor exposures. We develop a two-factor model with global and regional market shocks as factors. We make the global and regional market exposures conditional upon both a latent regime variable and three structural instruments, and find that, for a set of 14 European countries, this model outperforms more restricted versions. The structurally-driven increase in global (regional) market exposures and correlations suggest that market integration has increased substantially over the last three decades. Using our optimal model, we do not find evidence that further integration has come at the cost of contagion. We do find evidence for contagion, however, when more restricted versions of the factor specifications are used. We conclude that the specification of the global and regional market exposures is an important issue in any test for contagion.  相似文献
