In a large sample of European firms we analyze the value discount associated with disproportional ownership structures first documented by Claessens et al. (2002). Consistent with a theoretical model of incentive and entrenchment effects, we find higher value discount in family firms, in firms with low cash flow concentration, and in industries with higher amenity value. Furthermore, the discount is higher in countries with good investor protection and higher for dual class shares than for pyramids. We find no impact on operating performance, likelihood of bankruptcy, dividend policy, or growth. Finally, we discuss policy implications of these findings.  相似文献

A taxonomy of segmentation bases is presented which builds a multi-disciplinary approach to the categorization of suppliers. Supplier segmentation, from a purchasing perspective, still appears to be in the early stages of providing a coherent strategic intent behind supplier assessment. Whilst fragmentary in nature, current portfolio models are grouped into two principal taxonomic constructs of power and dependence and relational factors. In particular, the prevalent use of transaction cost economics (TCE) in portfolio modelling provides a foundation for purchasers to appraise risks from supplier opportunism. We augment existing approaches with reference to inter-organisational theory and the resource-based view to show different modes of inter-firm value creation that act as constituents of a strategic intent for segmentation. Our resulting taxonomy draws together a holistic view of supplier segmentation covering supply market conditions, product/service characteristics, supplier characteristics, buyer characteristics, and buyer-supplier relational factors.  相似文献

The paper is concerned with PPP in the telecommunications area and more specifically with the combination of public and private investments in upgrading broadband infrastructures. Following the liberalization of the telecommunications area, investments were primarily left to the private sector – though public investments have continued to take place in specific areas such as research and education networks and rural and otherwise underserved areas. Lately, however, governments have upgraded their public investment plans in broadband infrastructures. The question is whether we are witnessing a simple quantitative change or whether this quantitative change includes a qualitative evolvement in the view on the role of the public sector in expanding broadband infrastructures. At the present time, the most likely answer is that increasing public investments in broadband infrastructures signal a combination of concerns raised by the economic crisis and the growing awareness of the social and economic importance of efficient broadband infrastructures.  相似文献

We suggest improved tests for cointegration rank in the vector autoregressive (VAR) model and develop asymptotic distribution theory and local power results. The tests are (quasi-)likelihood ratio tests based on a Gaussian likelihood, but as usual the asymptotic results do not require normally distributed innovations. Our tests differ from existing tests in two respects. First, instead of basing our tests on the conditional (with respect to the initial observations) likelihood, we follow the recent unit root literature and base our tests on the full likelihood as in, e.g., Elliott et al. (1996). Second, our tests incorporate a “sign” restriction which generalizes the one-sided unit root test. We show that the asymptotic local power of the proposed tests dominates that of existing cointegration rank tests.  相似文献

Europe has been the first region to intervene on the market for international roaming services. The first regulation was introduced in 2007 and has since then been revised several times. The latest revision took place in the summer 2012. This paper discusses the new legislation in view of recent market developments from a technological, economic and a regulatory perspective. The paper concludes that roaming charges have been reduced substantially since the introduction of prices caps, but still the charges are far above a level, which can be justified by the production costs. A number of alternatives to tradition roaming have been developed, but so far their impact on competition have been limited, and it will take some years before the present regulation can be lifted.  相似文献

We conduct an empirical evaluation of a static super-replicating hedge of barrier options. The hedge is robust to uncertainty about the future skew. Using almost seven years of current data on the DAX, we evaluate the performance of the hedge and compare it with those of both a dynamic and a static replicating hedge. The main result is that the robustness of the static super-replicating portfolio is also empirically confirmed in practice such that the hedge sets an upper bound for the price of skew risk for barrier options.  相似文献

This paper focuses on behavioural reasons underlying stated attribute non-attendance in choice experiments. In order to identify and incorporate procedures for dealing with heterogeneous attribute processing strategies, we ask respondents follow-up questions regarding their reasons for ignoring attributes. Based on these statements, we conclude that the standard way of assigning a zero impact of ignored attributes on the likelihood is inappropriate. We find that some respondents act in accordance with the passive bounded rationality assumption since they ignore an attribute simply because it does not affect their utility. Excluding these genuine zero preferences, as the standard approach essentially does, might bias results. Other respondents claim to have ignored attributes to simplify choices. However, we find that these respondents have actually not completely ignored attributes. We argue along the rationally adaptive behavioural model that valid preference information may indeed be elicited in these cases, and we illustrate how recoding of non-attendance statements conditional on stated reasons may be a more appropriate solution than the current standard way of taking stated non-attendance into account.  相似文献

This paper explores the possibility that utilizing the firm's knowledge resources to complete important tasks can backfire and undermine competitive performance. Drawing on organizational capabilities and knowledge‐sharing research, we develop a situated performance view that holds that the value of obtaining and using knowledge within a firm depends on the task situation. Using a data set of 182 sales proposals for client work in a management consulting company, we show that sales teams that had varying needs to learn and differentiate themselves from competitors derived different levels of value from obtaining and using electronic documents and advice from colleagues. Highly experienced teams were more likely than inexperienced teams to lose the sales bids if they utilized such knowledge. Teams that had a high need to differentiate themselves from competitors also had a lower chance of winning if they utilized electronic documents. There were situations, however, where teams performed better if they utilized the firm's knowledge resources. These results suggest that competitive performance depends not on how much firms know but on how they use what they know. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

We estimate individual risk attitudes using controlled experiments in the field in Denmark. The experiments were carried out across Denmark using a representative sample of 253 people between 19 and 75 years of age. Risk attitudes are estimated for various individuals differentiated by socio‐demographic characteristics. Our results indicate that the average Dane is risk averse, and that risk neutrality is an inappropriate assumption to apply. We also find that risk attitudes vary significantly with respect to several important socio‐demographic variables such as age and education. However, we do not find any effect of sex on risk attitudes.  相似文献

How does the implementation of SCM strategies affect the organisation of procurement? Based on case study material of 15 Danish companies, this article develops a set of statements concerning the organisational role and job assignments of procurement in the light of SCM practice. For this purpose, we use an analytical technique known as the degree-of-freedom analysis. It is suggested that new organisational practices, such as key supply management, team-based management and changing skill requirements of purchasing personnel, may be an outcome of implementing SCM practices towards suppliers. Implications for theory and practice.  相似文献
