This paper investigates the link between firms' geographic configuration and market power in imperfect markets. We consider two related setups. The first illustrates the relevant characteristics of the pricing equilibrium. A main implication is that the equilibrium price vector changes in accordance with the firms' spatial configuration. The second, where firms operate as downstream retailers affiliated to rival upstream wholesalers, shows that upstream market power is strongly affected by an index of geographic concentration which reflects the spatial configuration of retailers. Finally, our analysis provides several insights for market delineation as well as merger evaluation and remedies.  相似文献

The great financial crisis widened the role of financial intermediation in financial stability. This study develops a new financial intermediation variable, credit cash flow (CCF), which enables measurement of the net financial flow resulting from loan activity. An analysis provides evidence that CCF affects the capital buffer via credit gap behaviour, thus indicating the existence of a channel between the CCF and the capital buffer. Such a link offers the policy-maker the possibility to monitor the behaviour of financial intermediation carried out by banks, in order to avoid the outbreak of financial instability events.  相似文献

The objective of this study is to identify the weighted importance of intrinsic and extrinsic attributes. Intrinsic attributes are defined as the specific features of products. Extrinsic attributes refer to other characteristics that are also important for price composition, such as brand, store layout and services, and purchasing experiences. In a survey with 1,923 collected responses, it was possible to identify and quantify intrinsic and extrinsic influencing factors beyond price strategy in the Brazilian fashion market for blue jeans. The statistical analysis was based on the hedonic price method. The idea of expressing the price based on a series of intrinsic and extrinsic variables avoids the problem of using the regression technique. In this research, multiple linear regression and quantile regression were applied. The results show that extrinsic attributes have greater influence than intrinsic features on explaining the final market prices using log-linear and quantile regression statistical methods.  相似文献

In contemporary business and academia, design has been increasingly viewed as an important strategic asset such that several scholars and executives have recently investigated the links among design, innovation and competitive advantage. Indeed, recent and emerging literature streams are exploring the potential contribution design can provide in valorising and differently adopting new or existing technologies [Dell’Era, Marchesi, and Verganti 2010. “Mastering Technologies in Design-Driven Innovation – How Two Italian Companies Made Design a Central Part of their Innovation Process.” Research Technology Management 53 (2): 12–23 Buganza et al. 2015. “Unveiling the Potentialities Provided by New Technologies: A Process to Pursue Technology Epiphanies in the Smartphone App Industry.” Creativity and Innovation Management 24 (3): 391–414]. This paper aims to investigate the design managerial practices able to support Technology Epiphanies, which are defined as the discovery of quiescent meanings in new or existing technologies [Verganti 2009. Design-Driven Innovation. Changing the Rules of Competition by Radically Innovating What Things Mean. Boston: Harvard Business Press]. The paper relies on four in-depth case studies developed by both primary and secondary sources: Nintendo, Kartell, Technogym and KUKA Robotics. The paper identifies three design management practices that can guide managers in the development of Technology Epiphanies: interpreting technology as an enabling platform, building double-sided network and accessing new knowledge domains.  相似文献

Today many companies in many industries put a lot of efforts into monitoring and investigating emerging drivers of change in their business environment, particularly in relation to new technologies and events in the social, economic, political and ecological landscapes which surround their industry. So far scholars in the literature on foresight and future studies focused on the techniques and practices for analysing the “state” uncertainty about the likely path of evolution of emerging drivers of change. Anyway, less attention was devoted to the “effect” uncertainty about the impact of drivers of change on the competitive position of the firm and to the “response” uncertainty about how to take advantage of these drivers. These are the main issues we take into account, through a field research on firms that, notwithstanding they were able to properly assess the likely evolution (state uncertainty) of relevant drivers of change in their industry, either were successful or dramatically failed in handling the effect and response uncertainty of these drivers. Moreover, we carried out multiple case studies of some large companies that have established an organizational unit dedicated to strategic foresight. Overall, the results of our research may contribute to improve the effectiveness of strategic foresight and to increase its value added to the planning process of corporate firms, while providing helpful insight to public organizations that promote foresight exercises for enhancing the competitiveness of local firms.  相似文献

Computing value at risk with high frequency data   总被引:2,自引:0,他引:2  
We compare the computation of value at risk with daily and with high frequency data for the Deutsche mark–US dollar exchange rate. Among the main points considered in the paper are: (a) the comparison of measures of value at risk on the basis of multi-step volatility forecasts; (b) the computation of the degree of fractional differencing for high frequency data in the context of a Fractionally Integrated Generalized Autoregressive Conditional Heteroskedasticity (FIGARCH) model; and (c) the comparison between deterministic and stochastic models for the filtering of high frequency returns.  相似文献

This paper analyzes games with imperfectly enforceable agreements. It develops a dynamical model in which players are randomly paired into single shot games at each moment. Initially players decide whether to honor an agreement, and then they choose whether to complain to an enforcement agency. The probability of success of a complaint is endogenous; it depends upon whether the defendant breached and upon the aggregate behavior of all players. In the most interesting equilibria of the dynamical system some individuals honor and some individuals complain while others do not, and the net effect of the existence of an enforcement agency is positive.Journal of Economic LiteratureClassification Number: C72.  相似文献

商业银行反周期资本缓冲的方法选择   总被引:2,自引:0,他引:2  
本文提供了设计反周期资本缓冲的一些经验教训和方法选择,主要贡献在于分析了用于指引资本缓冲建立和释放的条件变量。不同反周期资本措施的主要区别在于条件变量是银行特定的还是系统性的,前种方法对特定构成要素的数量要求巨大,相比之下系统性的方法更具优势。作为资本缓冲增加进度和规模信号的最佳变量未必是指引资本缓冲释放时机和程度的最佳变量。信贷/GDP比率是指引建立阶段开始的最好变量,总损失的某种衡量,与信贷条件指标一起,可以很好地发出释放资本的信号。不过,现阶段设计完全以规则为基础的机制不太可能,不同程度的主观判断不可避免。此外,本文还认为,减少最低资本要求的敏感性是可靠的反周期缓冲措施的重要组成部分。在本次金融危机发生之后,反周期资本管理正逐渐引起国内银行业及相关部门的重视,本刊征得作者同意,翻译并发表此文,以期为相关部门资本监管和风险管理提供借鉴。作者及所在机构对译文免责。  相似文献

Foodborne diseases are a major public health problem. Improper storage and food preparation at home can favour microbial contamination of food. Consumers play a crucial role in controlling this risk. To reduce exposure to risk, it is essential to provide information and guidance on contamination management in the home. The aim of this study was to pilot a method of participatory communication addressed to young consumers and designed to reduce the microbiological risks associated with the consumption of meat products. The methodology was based on application of the ‘consensus conference’ model on food safety issues. The consensus conference served not only as a participatory strategy to share knowledge but also as a method for sharing in the development of risk communication content (guidelines) to be disseminated to the reference target. Young people’s perceptions, habits and behaviour in the kitchen were explored in the preparatory stage of the consensus conference by means of a survey and a focus group. Three consensus conferences were held in Italy attended by 60 university students (19 and 22 years old). Application of the consensus conference model as a communication process proved to be an effective opportunity to engage young consumers and experts on the topic of food safety. This discursive participation approach was broadly welcomed by the participants. Specifically, direct interaction with the experts was considered to be an important part of the communication process. The findings of the project were used to select concise communication content based on the perceptions, behaviours and fact-finding needs of the selected target. Publication of this content in the form of guidelines on microbiological risk management at home has enabled the results of the consensus conferences to be extended and the targeted communication material on risk reduction in daily food handling practices to be disseminated.  相似文献
