The EU's evolving stance on the international dimension of competition policy: A critical commentary
In recent years there has been a rapid increase in both the numbers and the value of cross-border mergers and acquisitions.
As more and more competition cases fall within the jurisdiction of two or more competition authorities, the possibility of
divergent and unpredictab]le outcomes increases. This article explores the response of the European Union to international
competition concerns that impact on its, jurisdiction. 相似文献

This paper uses the existence of secondary markets for debt instruments with default risk (e.g. corporate bonds) to define default insurance along the lines of financial economics. It examines whether, in the case of several risk-neutral measures, characteristics of default can be uniquely determined by the prices of contracts involving default-prone securities. 相似文献

Abstract. This paper studies the effects of crises on human capital formation. Theoretically, a crisis undermines total factor productivity, which reduces the return to working and to accumulating physical capital. If the crisis is temporary, young agents will study now and work later. Human capital rises. To test our model we rely on inflation crises as our main empirical proxy. Using GMM panel procedures, our analysis for 86 countries in 1970–2000 confirms the positive effects of crises on human capital. Our main findings survive several robustness tests.

Developers usually presell new condominiums, requiring purchasers to make down payments on a contract that allows them to
purchase, at a fixed price, the finished condominiums on a later date. This presale contract is akin to a financial call option
sold by the builder to the purchaser of the condo. In this paper, we value the presale contract from both the purchaser’s
and the developer’s points of view. We examine the influence of various opt-out clauses, different interest rates and other
factors on the value of presale contracts. We discuss the extent of risk sharing between the purchasers and the developers
according to varying levels of down payments. We conclude that developers enjoy a reduction in risk without a corresponding
reduction in expected profits by holding a presale. 相似文献

We consider the class of law invariant convex risk measures with robust representation rh,p(X)=supfò01 [AV@Rs(X)f(s)-fp(s)h(s)] ds\rho_{h,p}(X)=\sup_{f}\int_{0}^{1} [AV@R_{s}(X)f(s)-f^{p}(s)h(s)]\,ds, where 1≤p<∞ and h is a positive and strictly decreasing function. The supremum is taken over the set of all Radon–Nikodym derivatives corresponding
to the set of all probability measures on (0,1] which are absolutely continuous with respect to Lebesgue measure. We provide
necessary and sufficient conditions for the position X such that ρ
h,p
(X) is real-valued and the supremum is attained. Using variational methods, an explicit formula for the maximizer is given.
We exhibit two examples of such risk measures and compare them to the average value at risk. 相似文献

Collusion seems to be a pervasive problem when regional monopoly rights are auctioned to private firms. This leads us to study whether firms may collude if the regulator uses yardstick competition to simulate competitive forces, and how collusion is affected when both schemes are used. Using an infinitely repeated game framework, we find that collusion is sustainable when firms are sufficiently patient under yardstick competition. An additional franchise bidding mechanism can even help firms sustain collusion when they are impatient. When temporary monopoly rights are assigned for sufficiently long periods of time, collusion may not be sustainable even when firms are patient. 相似文献

Organizations are increasingly relying on Internet searches and social networking websites to uncover detailed and private
information about job applicants. Such Internet screening techniques have the potential to provide additional information
beyond that found using traditional screening approaches. However, questions regarding the legality and appropriateness of
this practice, as well as issues regarding the standardization, reliability, and validity of the information obtained, need
to be addressed. The current work describes these issues associated with Internet screening and provides recommendations to
help ensure this practice is used appropriately in organizations. Suggestions for future research on Internet screening are
also discussed. 相似文献

This article describes how 2 forms of groupware - electronic Mail and Group Support Systems (GSS) were employed to support user requirements specification in a university department. The system being specified was a bibliographic information system, while the users were both qualified systems analysts and academic staff in the department. The background literatures to both requirements specification and GSS are introduced and linked. Groupware tools were used to support the group interaction and consensus formation. The article discusses the key stages in this process and discusses the appropriateness of the techniques used. The results are significant in that they identify techniques appropriate to supporting user groups in the clarification of system requirements before the involvement of development personnel. 相似文献

In the present contribution, we characterise law determined convex risk measures that have convex level sets at the level of distributions. By relaxing the assumptions in Weber (Math. Finance 16:419–441, 2006), we show that these risk measures can be identified with a class of generalised shortfall risk measures. As a direct consequence, we are able to extend the results in Ziegel (Math. Finance, 2014, http://onlinelibrary.wiley.com/doi/10.1111/mafi.12080/abstract) and Bellini and Bignozzi (Quant. Finance 15:725–733, 2014) on convex elicitable risk measures and confirm that expectiles are the only elicitable coherent risk measures. Further, we provide a simple characterisation of robustness for convex risk measures in terms of a weak notion of mixture continuity. 相似文献
