摘要

结果不确定性(OU)和竞争平衡(CB)的分析在体育经济学中具有十分重要的意义。令人惊讶的是，几乎没有关于游戏结构对OU或CB的影响的研究。平衡和不平衡的时间表，分工发挥已被用来分析偏差的CB措施。并分析了不平衡调度的引入对OU的影响。但是不平衡赛程和赛区比赛的引入对OU的影响还没有被分析。在本文中，我们评估了在给定CB选择(OU/CB)的情况下，移动到分组游戏对OU的影响。这包括赛程不平衡、赛区强度、队伍数量和赛区数量的影响。我们还通过数值分析和回归估计了它们对OU/CB的边际影响。对于美国职业棒球大联盟引入分区比赛的情况，将结果与来自无偏估计的OU/CB进行比较。结果表明，该方法是有用的，并具有政策意义。

Division Play and Outcome Uncertainty in Sports Leagues

The analysis of outcome uncertainty (OU) and competitive balance (CB) has been of overwhelming importance in sports economics. Surprisingly, there is little work on the impact of the structure of play on either OU or CB. Balanced and unbalanced schedules, and division play have been used to analyze biasedness of CB measures. And the impact of the introduction of unbalanced schedules on OU has been analyzed. But the impact of the introduction of both unbalanced schedules and division play on OU has not been analyzed. In this paper, we assess the impacts on OU, for given choices of CB (OU/CB) of moving to division play. This includes the impact of schedule imbalance, division strength, the number of teams, and the number of divisions. We also obtain estimates of their marginal impacts on OU/CB via numerical analysis and regression. The results are compared to OU/CB from unbiased estimators, for the case of the introduction of division play in Major League Baseball. The results suggest that the approach is useful and there are policy implications.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
