The assessment of exclusionary abuses by dominant firms is byno means an easy task. This is particularly true for pricingabuses, as there is no clear-cut way of distinguishing a pricecut that is abusive from one that instead is pro-competitive.We argue that there are several shortcomings in the way theEuropean Commission as assessed exclusionary pricing abusesin two important decisions concerning Internet access servicemarkets: Deutsche Telekom AG and Wanadoo Interactive. Firstof all, in computing downstream costs to apply the price squeezetest the incumbent's economies of scale and unavoidable costsshould be factored in, as the test is only meant to establishwhether an as-efficient competitor has been unlawfully foreclosed.Secondly, since the price squeeze test provides only for a necessarycondition for predation to occur, it is also necessary to provethat the recoupment of initial losses is a plausible scenarioso that the conduct under examination may indeed turn out tobe harmful to consumers. This is all but a trivial task, asthere are some sources of endogeneity that may cause a radicalchange in the underlying market structure. Particularly, inmarkets at early stage of development, entry barriers that mayfacilitate the recoupment of initial losses ex-ante may causea change such that market structure no longer supports recoupmentex-post. 相似文献

This paper introduces the articles in the symposium which address the issue of democratic accountability and economic voting in polities on the European periphery. The economic crisis that hit the world economy in 2008 has severely challenged the capacity of governments to steer the national economy and has had a strong impact on their electoral support. The papers discuss whether economic voting and democratic accountability are increasing or, on the other hand, they could be depressed by globalisation and by shifts of ruling competence from the national to the supranational European arena. 相似文献

This article looks at performance information use by legislators at the central level in a budgetary context. The multi‐method approach (interviews, quantitative and qualitative analysis of plenary speeches given during budget readings) allows us to draw a broader picture of the use of performance information. The findings provide new insights into different purposes of performance information use. We identify four general use types, that is, de‐legitimizing, legitimizing, improving and understanding, and deflecting, which together with the subjects addressed blend into different use purposes. Second, the study sheds light onto different factors affecting performance information use, that is, the attributes of users of performance information, the properties of performance, and the role of institutional support. 相似文献

This paper analyses the economic value of foreign languages in Turkey using data on some 6000 adult male wage-earners in 2007. We find positive earnings returns to proficiency in English and Russian, which increase with the level of competence. French and German skills are also positively rewarded, although their return seems mostly linked to the likelihood to hold specific occupations. In contrast, knowing Arabic does not generate an earnings premium. Focusing on English, we check for heterogeneous returns along the conditional earnings distribution. The results are qualitatively invariant when we account for misclassification errors in self-reported English skills. 相似文献

The body of a 30‐year‐old woman was found in Como lake at a depth of about 120 meters in her own car after 3 years of immersion. The aim of this study was to evaluate psychoactive drugs as well as alcohol biomarkers in biological matrices. The following analyses were initially performed: GC‐MS systematic toxicological analysis on biological fluids and tissues; GC‐MS analysis of drugs of abuse on pubic hair; direct ethanol metabolite determination in pubic hair by LC‐MS/MS. After 7 years, the samples, that had been stored at ?20°C, were re‐analyzed and submitted to an LC‐MS/MS targeted screening method, using multiple reaction monitoring mode. These analyses detected citalopram (150–3000 ng/mL), desmethylcitalopram (50–2300 ng/mL), clotiapine (20–65 ng/mL), and ethyl glucuronide (97 pg/mg). The methods showed an acceptable reproducibility, and the concentrations of citalopram and desmethylcitalopram calculated through the two analytical techniques did not significantly differ in biological fluids. 相似文献

In the context of the increasing securitisation of cultural heritage, France, Italy, and the United Kingdom have reacted differently to the recent wave of iconoclasm perpetrated by the Islamic State of Iraq and Syria (ISIS) and similar radical groups and terrorist organisations. With cultural heritage now discursively identified as a security concern, the three states enacted security practices to deal with the newly emerged security threats. All three cases show a tight association between the protection of cultural heritage, development and security policies. State-driven cultural heritage protection policies continue to be designed around the notion of multilateral cooperation, although innovative forms of public-private multilateralism and civil-military cooperation are increasingly being introduced. 相似文献
