Culturally-Biased Voting in the Eurovision Song Contest: Do National Contests Differ?

The economic literature on the Eurovision Song Contest (ESC) establishes empirical evidence for culturally-biased voting, more precisely also biases based on geographical closeness, political relations, ethnical and linguistic affinity. The Bundesvision Song Contest (BSC), a similar contest with principally the same rules but organized on the national level in Germany, offers a unique opportunity to compare international voting bias patterns to national voting bias patterns. Thus, this paper presents an innovative analysis by comparatively analyzing the ESC's historical data from 1998 to 2013 and the BSC's data from its beginning in 2005 until 2013 with the same econometric methodology. Our results show that voting biases do not only matter in international contests but also occur in similarly-organized national contests with roughly similar magnitude and quality - despite the cultural background of participants and voters being much more homogenous

The (Monetary) Value of Competitive Balance for Sport Consumers: A Stated Preferences Approach to European Professional Football

Ever since the pioneering work of Rottenberg (1956) and Neale (1964), the uncertainty of outcome hypothesis (UOH) has played a major role in the economic analysis of professional sport leagues. However, decades f empirical research have not been successful in establishing clear evidence for the importance of competitive balance (CB) for attendance or TV viewers in European professional football. In order to find possible reasons for the gap between the UOH and (the lack of) its empirical validation, our paper adopts a stated preference approach focused on the fans' perception of CB and its relevance in three European professional football leagues. The results indicate that a tipping point/threshold value of CB exists and that crossing this threshold can lead to massive demand eactions. However, since the threshold has not been reached in the leagues included in the sample, the paper provides a possible explanation for the above mentioned gap

Are Restrictions of Competition by Sports Associations Horizontal or Vertical in Nature?

In this paper, we discuss from an economic perspective two alternative views of restrictions of competition by sports associations. The horizontal approach views such restrictions as an agreement among the participants of a sports league with the sports association merely representing an organization executing the horizontal cooperation. In contrast, the vertical approach views the sports association as being a dominant upstream firm enjoying a monopoly position on the market stage for competition organizing services, an important input for the actual product - the sports game. Taking the recent financial fair play (FFP) initiative by UEFA (the Union of European Football Associations) as an example, we demonstrate that the different views lead to different assessments of restrictive effects and, thus, matter for competition policy decisions. The economic story of the potential restrictive effect of FFP on players' and player agents' income may fit more plausibly to the horizontal approach, whereas the potentially anticompetitive foreclosure and deterrence effects of FFP may be economically more soundly reasoned by taking the vertical view

Lactate Produced by Glycogenolysis in Astrocytes Regulates Memory Processing

When administered either systemically or centrally, glucose is a potent enhancer of memory processes. Measures of glucose levels in extracellular fluid in the rat hippocampus during memory tests reveal that these levels are dynamic, decreasing in response to memory tasks and loads; exogenous glucose blocks these decreases and enhances memory. The present experiments test the hypothesis that glucose enhancement of memory is mediated by glycogen storage and then metabolism to lactate in astrocytes, which provide lactate to neurons as an energy substrate. Sensitive bioprobes were used to measure brain glucose and lactate levels in 1-sec samples. Extracellular glucose decreased and lactate increased while rats performed a spatial working memory task. Intrahippocampal infusions of lactate enhanced memory in this task. In addition, pharmacological inhibition of astrocytic glycogenolysis impaired memory and this impairment was reversed by administration of lactate or glucose, both of which can provide lactate to neurons in the absence of glycogenolysis. Pharmacological block of the monocarboxylate transporter responsible for lactate uptake into neurons also impaired memory and this impairment was not reversed by either glucose or lactate. These findings support the view that astrocytes regulate memory formation by controlling the provision of lactate to support neuronal functions
