Transfer restrictions have a long tradition in professional sports but came under heavy attack in recent years (e.g. Bosman
ruling, Monti system). Based on a bargaining model with stochastic player productivity, we show that less restrictive transfer
rules reallocate ex post bargaining power from players to clubs. This reallocation is efficient and in the ex ante self-interest
of players. The right to charge transfer fees enables clubs to insure their players. The players, in turn, benefit by converting
risky future income into riskless current income. Overall, player utility is higher under more than under less restrictive
transfer rules.

Illness is rarely considered a “risk factor” in adolescence. This study tests illness, suicidality and substance use as outcome
measures in a path analysis of 1028 Swiss adolescents in secondary prevention programs. The model showed that negative mood
(depression and anxiety) predicted two paths. One path led from negative mood to suicidality and from there to substance use.
The other path led directly from negative mood to illness. Traditional protective factors (good relationships, secure identity)
protected against the negative mood-suicide-substance path, but not against the negative mood-illness path.

Terminology like "evaluation research" and "policy analysis research" poses a fundamental conflict in talking about what constitutes legitimate inquiry activities. Using the two-part definition of disciplined inquiry developed by Cronbach and Suppes (1969). it is possible to characterize research, evaluation and policy analysis as three separate and distinct forms of disciplined inquiry. As distinct forms, each has its own unique definition, purpose(s), products, intended outcomes or effects, and audiences. Further, under the definitions proposed, emergent inquiry paradigms have as much utility as older, conventional models. 相似文献

Historically, European team sports leagues were run by their respective national and international associations and were legally independent from the professional clubs playing in these leagues. Recently, European leagues have adopted an organizational form similar to their North American counterparts who are organized since their beginning in a cooperative-like manner. Based on a comparative institutional analysis, we explain the advantages of the cooperative form of league organization over contractual governance. With our four-stage game-theoretic model, we show that contractual governance of sports leagues leads to larger investment distortions than cooperative league organization. 相似文献
