An assessment of the equality of access and no-regulation approaches to next generation networks

The European Commission believes that for the regulation of next generation fixed telecommunications networks the continuity approach is preferable to the equality of access approach and the no-regulation approach. According to the European Commission, (i) functional separation eliminates discrimination and promotes competition, but should only be used as a measure of last resort because it involves various complex trade-offs, whereas (ii) the no-regulation approach fosters investment, at the cost of sacrificing competition. The article agrees that functional separation involves complex trade-offs but disputes the assertion that functional separation necessarily eliminates discrimination and promotes competition. In addition, the article also establishes conditions under which the no-regulation approach does not reduce competition.     

Universal Enterprise Adaptive Object Model: A Semantic Web-Based Implementation of Organizational Self-Awareness

In this paper we present a novel conceptual model that systematizes the integrated management and adaptation of: (1) enterprise models, (2) their representations, (3) their underlying meta-models (i.e. their abstract syntax) and (4) the representation rules (i.e. concrete syntax for the respective models). All this for different modelling languages and also different versions of these languages. Thanks to our original use of the adaptive object model and type square patterns—normally applied in the context of software engineering, but here applied for enterprise engineering—we manage to provide a strong conceptual foundation for the development of software tools that allow a precise and coherent specification of models and their evolution and also of meta-models and their evolution. We also present a prototype of such a tool currently being developed to enable collaborative enterprise ontology model management using the Semantic MediaWiki as a base framework. This solution is solidly grounded on the theoretical foundations of organizational self-awareness and Ψ-theory of enterprise ontology and is a valuable contribution to facilitate general and distributed enterprise model management and also concrete and abstract syntax specification (i.e. the specification of a language's meta-model). This allows flexibility and ease of use in creation and adaptation of organizational models and also the use of semantic queries to detect and inform users on any violation of meta-model rules.

Perceived Benefits and Challenges to Wine Tourism Involvement: An International Perspective

This study extends institutional theory as a lens through which to critically examine the perceived benefits and potential challenges of developing wine tourism. The study applies an international perspective, with 471 participating wineries predominantly located in Italy and Spain. Fundamentally, the promotion of the winery's wines, distantly followed by the potential to significantly increase wine sales emerge as the main benefits winery respondents perceive from wine tourism. However, realizing these outcomes is not assured because of barriers including airport security checks, anti‐drink‐drive laws and limited physical resources. The implications from the findings are discussed, and opportunities for future research identified. Copyright © 2013 John Wiley & Sons, Ltd.     

Reversal in the relative performance of state- and legal person-owned companies during the Chinese split share structure reform

The split share structure reform was started in 2005 with the object of re-designating state-related, nontradable shares into tradable shares. The article compares the two major forms of state ownership in China (direct or indirect ownership) showing that, close to the reform period, companies directly held by the state experience a significant increase in market performance relative to indirectly held companies. Results suggest that investors’ perception about the worth of these two forms of state ownership may have suffered a reversal, thus bringing to light value-related consequences ensuing from protective schemes usual in China and elsewhere. The article also addresses a recurrent pitfall relating to the use in empirical models of fractions of the same total and shows that U-shaped patterns found in the relationship between ownership and performance are transient rather than stable.     

Setting Upper Limits on Merger Related Efficiencies

The purpose of this paper is to show that a complementary entry analysis could be performed by the authorities when assessing the welfare impacts of a merger. In addition to analyzing the likelihood and impact of post-merger entry by other firms, the authorities could also study pre-merger alternatives for the insiders, that is, to study wether other concentration operations were available but not chosen by the merging or acquiring firms. This may be particularly useful when the authorities are faced with a concentration operation that raises anti-competitive concerns. Insiders will argue that cost reductions are likely to compensate these negative effects. However, if the cost reductions are not firm specific it is possible, in some circumstances, to establish an upper limit on the extent of cost reductions when there are other mergers available. If these mergers were admissible but were dominated by the present one, information is revealed about the extent of cost reductions. This information may lead to the authorities updating their beliefs on efficiencies. Such updates may lead to the modification of the decision to approve or reject the merger.     

Working with Corporate Social Responsibility in Brazilian Companies: The Role of Managers’ Values in the Maintenance of CSR Cultures

Corporate social responsibility (CSR) refers to the duty of management to consider and respond to issues beyond the organization’s economic and legal requirements in line with social and environmental values. However, ‘management’ is constituted by real people responsible for routine decisions and formulation and implementation of policies. It can be said therefore that the ethical ideals and beliefs of these individuals – in particular their personal values – play an important role in their decisions. It is contended in this article that the personal values of managers may contribute to the creation and maintenance of ‘CSR cultures’ in their organizations; that is, organizational cultures focused on ensuring environmental and social sustainability. Based on an exploratory study carried out in Brazil in 2008, this article explores the perceptions of five CSR managers in relation to the influence of their personal values on their work. The first part discusses the notion of CSR within the context of Brazilian society, the second provides a brief literature review on the link between values and organizational cultures and the third explores the perceptions of the participating managers, identifying the main thematic patterns that emerged in the study.     

Financial consequences of cross-compliance and flat-rate-per-ha subsidies: The case of olive farmers on sloping land

Under the past Common Agricultural Policy (CAP) olive oil subsidy regime, farmers were eligible for subsidies on the basis of amount of olive oil produced. This led to an intensification of production and negative environmental effects on sloping land, such as loss of biodiversity and more soil erosion. In 2004 the olive and olive oil regime changed, with integration of support to olive farmers in the Single Payment Scheme (SPS). From 2006 to 2013 farmers receive a constant amount of subsidies, based on the average amount they received in the 4-year reference period 1999–2002.     

Evaluating an Alternative Risk Preference in Affine Term Structure Models

Dai and Singleton (2002) and Duffee (2002) show that there isa tension in affine term structure models between matching themean and the volatility of interest rates. This article examineswhether this tension can be solved by an alternative parametrizationof the price of risk. The empirical evidence suggests that,first, the examined parametrization is not sufficient to solvethe mean-volatility tension. Second, the usual result in theestimation of affine models, indicating that some of the statevariables are extremely persistent, may have been caused bythe lack of flexibility in the parametrization of the priceof risk.     

Production Chains and Linkage Indicators

This paper uses a framework of production chains, which emerge from the vertical integration processes, in order to propose a general definition of linkage indicators. This definition is based on blocks of sectors and offers, among others, the following advantages. A reduction in the aggregation requirement, the resolution of the problems associated with the so-called distribution matrices, an easier analysis of the linkage components and, finally, the possibility to shed light on the links between Hypothetical Extraction Methods and sectoral analyses. Moreover, because of its general form, it helps to identify analogies between different types of indicators.     

Preemptive mergers under spatial competition

Mergers for market power generally benefit outsider firms more than participating firms. Hence, outsiders should welcome such mergers between their competitors but, frequently, this is not the case. Under spatial competition some outsiders gain more than the participating firms but others might benefit less. Thus, if the number of admissible mergers is limited, firms may decide to merge to preempt rival mergers. This paper studies the incentives for preemptive merger by firms engaged in spatial competition.
