Transition metal oxynitride perovskites [AB(O,N)3] are an emerging class of inorganic materials with superior light harvesting ability (narrow band-gap energy) and moderate photostability. They can be utilized as visible-light-active photocatalysts for efficient solar water splitting. The...

Recently, zinc oxide (ZnO) has attracted much interest, owing to its efficient photocatalytic applications. Herein, we report the synthesis of pristine and Mn-doped ZnO photocatalyst with different nanostructures. The samples were synthesized via simple and low cost co-precipitation method. The...

A simple decision theoretic model shows the doping incentives for a member of a professional sports team. Depending on the detection probability and the punishment, a sportsman dopes not at all, at a medium or at the maximal level. The whole team has a higher incentive than an individual team...

Financial regulation in sports is usually discussed in the context of representing an instrument against "financial doping". Notwithstanding the merits of this discussion, this paper takes the opposite perspective and analyses how market-internal financial regulation itself may anticompetitively...

Die Entdeckungsquote identifizierter Dopingkonsumenten ist über die Zeit relativ stabil, wenn man die Aufklärungsquote von Welt-Anti-Doping-Agentur (WADA) bzw. Nationaler-Anti-Doping-Agentur (NADA) in Deutschland betrachtet. Wie immer, wenn sich soziale Verhaltensweisen und institutionelle...

An authority delegates a monitoring task to an agent. It can only observe the number of detected offenders, but neither the monitoring intensity chosen by the agent nor the resulting level of misbehavior. We provide a necessary and sufficient condition for the implementability of monitoring...

Unethical behavior within organizations is not rare. We investigate experimentally the role of status-seeking behavior in sabotage and cheating activities aiming at improving one’s performance ranking in a flat-wage environment. We find that average effort is higher when individuals are...

There is little evidence in support of the main economic rationale for regulating athletic doping: that doping reduces fan interest. The introduction of random testing for performance-enhancing drugs (PED) by Major League Baseball (MLB) offers unique data to investigate the issue. The...

Corruption in general and doping in particular are ubiquitous in both amateur and professional sports and have taken the character of a systemic threat. In creating unfair advantages, doping distorts the level playing field in sporting competition. With higher stakes involved, such distortions...

We analyze the doping behavior of heterogeneous athletes in an environment of private information. In a n-player strategic game, modeled as an all-pay auction, each athlete has private information about his actual physical ability and choses the amount of performance-enhancing drugs. The use of...

This paper studies the long-term impact of societal socialization on values using the example of doping behavior in sports. We apply the German Reunification Approach to the microcosm of Berlin and exploit its 40-year long division into a capitalist and a communist sector. We deliberately chose...

To which extent high performances in professional sports are based on the use of illicit substances or other doping practices is extremely difficult to measure empirically. Game-theoretical approaches predict strong incentives to dope based on the interaction among athletes (prisoner's dilemma)...

Referentinnen und Referenten, die in Fragen der Olympischen Spiele, der Olympischen Idee, aber auch in Olympischen Problemen sachkundig und ausgewiesen sind, haben sich in einer Ringvorlesung an der Universität des Saarlandes einer Frage gewidmet: Sind Olympische Spiele noch zeitgemäß? Dabei...

Neben der Bewahrung der olympischen Idee und der Organisation der Olympischen Spiele liegt die Vermarktung des Wettbewerbs im Aufgabenbereich des IOC. Hierbei wird jedoch nicht nur die sportliche Leistung im Wettkampf vermarktet, sondern ein komplementäres Gut, bestehend aus der sportlichen...

Der Zusammenhang zwischen Populationsgröße und Bruttoinlandprodukt und der Zahl der olympischen Medaillen eines Landes wurde mehrfach in der Literatur nachgewiesen. Wir zeigen, dass dieser Zusammenhang in der DDR systematisch durchbrochen wurde. Die SEDFührung hat seit etwa 1970 mittels...

We apply ideas put forward in the literature on the international coordination of macroeconomic and trade policies to study the merits of an international coordination of antidoping policies. Without international coordination of antidoping policies, sports associations and national anti-doping...
