The judicial fear of vertical market foreclosure has been criticized severely in the academic literature. The focus of this criticism isnot that foreclosure is impossible; rather, it is that foreclosure is not a profitable business strategy. In this note, we show that this criticism is not valid under conditions of partial ownership. If effective vertical control can be achieved with partial ownership, vertical market foreclosure can be used to increase the partial owner's profits. We use theduPont (GM) litigation as a vehicle to explore this point. 相似文献

Out of the ongoing debate on what constitutes predatory behavior has surfaced the idea that it must entail a sacrifice of profits. The notion is that behavior which sacrifices profits must have an ulterior motive, namely an attempt to induce exit by rivals. This note makes the point that when incumbents must make choices before the resolution of uncertain events, a policy which sacrifices expected profits could be motivated by risk reduction. The issues surrounding the identification of predatory behavior in the presence of uncertainty are discussed, and a definition of predation which allows for uncertainty is presented. 相似文献

Learning, Teamwork and Appropriability: Managing Technological Change in the Department of Social Security 总被引:1,自引:0,他引:1
Drawing on an extensive case study, we argue that management has to actively manage information flows, both within the organization and between the organization and its environment. Three tasks of knowledge management are, in our view, important in building technological capability: appropriation, teamworking and learning. 'Appropriation' includes the retention and effective utilization of internal knowledge. 'Teamworking' refers to the integration of diverse knowledge bases. 'Learning' embraces the acquisition and exploitation of externally held knowledge 相似文献

The banking/investment sector must deal with a new variable, Operational Risk, for explaining various recent crises and bankruptcies. Operational Risk, which can be defined briefly as the risk generated by possible failures of a entity's Information Systems (IS), must be measured, covered, mitigated and managed by applying a series of methodologies, each of which assumes that the IS of the bank operates at a certain Stage of Sophistication. The present study proposes a scheme of evolution that details the stages of enhancement in the sophistication of their IS that banking entities may implement, so as to be capable of capturing, mitigating and managing Operational Risk. Using econometric methods, we create a proxy variable to capture the IS Sophistication of each entity. Then, the factor of entity size has been analyzed, and the country effect is explored. Additionally, the importance of intangible assets is weighted, among others entity aspects. The entity size has been revealed as the variable with most influence on the plans formulated in this respect by European entities, against other variables also considered in the present study, such as the country effect or the importance of intangible assets. The work shows how IS decisions referring to Operational Risk management are very influenced by size. It could introduce competition differences in the European banking system. 相似文献

The Core of Consistency in AHP-Group Decision Making 总被引:2,自引:1,他引:1
This paper presents a new tool, the Consistency Consensus Matrix, designed to encourage the search for consensus in group
decision making when using the Analytic Hierarchy Process (AHP). The procedure exploits one of the characteristics of AHP:
the possibility of measuring consistency in judgement elicitation. Using two other tools, Preference Structures and Stability
Intervals, we derive the Consistency Consensus Matrix that corresponds to the actor’s core of consistency. The performance
analysis of the preference structure obtained from this matrix provides us with valuable information in search for knowledge.
The new tool is illustrated by means of a case study adapted from a real-life experiment in e-democracy developed for the
City Council of Zaragoza (Spain). 相似文献

In an incomplete market framework, contingent claims are of particular interest since they improve the market efficiency. This paper addresses the problem of market completeness when trading in contingent claims is allowed. We extend recent results by Bajeux and Rochet (1996) in a stochastic volatility model to the case where the asset price and its volatility variations are correlated. We also relate the ability of a given contingent claim to complete the market to the convexity of its price function in the current asset price. This allows us to state our results for general contingent claims by examining the convexity of their "admissible arbitrage prices." 相似文献

International Business (IB) theories encompass economic approaches, where firms use objective criteria to select foreign markets, and behavioral approaches, where firms use psychic distance. This study proposes new objective criteria to measure psychic distance and adopts multiple linear regressions with a foreign-trade econometric model adapted to address psychic distance and market size and their relationships with Brazilian exports over 10 years. Psychic distance showed a close relationship to exports from smaller firms, while the market size of the destination country was always significant. This brought original empirical evidence to the validity of IB theories as well as to the exports behavior of firms from emerging economies. 相似文献

Market failure can be corrected using different regulatory approaches ranging from high to low intervention. Recently, classic regulations have been criticized as costly and economically irrational, and thus, policy makers are giving more consideration to soft regulatory techniques such as information remedies. However, despite the plethora of food information conveyed by different media there appears to be a lack of studies exploring how consumers evaluate this information and how trust towards publishers influence their choices for food information. In order to fill such a gap, this study investigates questions related to topics that are more relevant to consumers, who should disseminate trustful food information, and how communication should be conveyed and segmented. Primary data were collected both through qualitative (in‐depth interviews and focus groups) and quantitative research (web and mail surveys). Attitudes, willingness to pay (WTP) for food information and trust towards public and private sources conveying information through a new food magazine were assessed using both multivariate statistical methods and econometric analysis. The study shows that consumer attitudes towards food information topics can be summarized along three cognitive‐affective dimensions: the agro‐food system, enjoyment and wellness. Information related to health risks caused by nutritional disorders and food safety issues caused by bacteria and chemical substances is the most important for about 90% of respondents. Food information related to regulations and traditions is also considered important for more than two‐thirds of respondents, whereas information about food production and processing techniques, lifestyle and food fads are considered less important by the majority of respondents. Trust towards food information disseminated by public bodies is higher than that observed for private bodies. This behaviour directly affects WTP for food information provided by public and private publishers when markets are shocked by a food safety incident. WTP for consumer association (€1.80) and the European Food Safety Authority (€1.30) are higher than WTP for the independent and food industry publishers that cluster around zero euro. Furthermore, trust towards the type of publisher also plays a key role in food information market segmentation together with socio‐demographic and economic variables such as gender, age, presence of children and income. These findings invite policy makers to reflect on the possibility of using information remedies conveyed using trusted sources of information to specific segments of consumers as an interesting soft alternative to the classic way of regulating modern food markets.

We provide a competitive equilibrium theory of urban segregation in a linear city. Households demand consumption and housing along the city and are exposed to neighborhood externalities. We show that equilibria that are robust to small coalitional deviations are segregated. Our results explain urban segregation in a standard neoclassical framework and shed new light on the difficulties faced by authorities to integrate cities. 相似文献
