    Abstract: Even though insufficient participation in physical activity is shown to be one of the major contributors to chronic diseases, and poor health, participation in physical activity still remains to be substantially low in developed countries including Canada. In this paper, we examine the long-run health effects of participation in sports and exercise among inactive Canadian adults. Based on informative Canadian panel data and semiparametric matching estimation, we show that participation in sports and exercise generally improves physical health and mental well-being of individuals. While this effect is statistically significant and persistent for men, we do not find a similar effect for women. Our results also indicate that positive health effects are only achieved with a level of physical activity that is larger than the current national and international health organizations' guidelines for the minimum level of activity.

  2. By: Emara, Noha; Owens, David; Smith, John; Wilmer, Lisa
    Abstract: We investigate the strategic behavior of highly informed agents playing zero-sum games under highly incentivized conditions. We examine data from 3455 National Football League (NFL) games from the 2000 season through the 2012 season, and categorize each play as "rush" or a "pass." We find that the pass-rush mix exhibits negative serial correlation: play types alternate more frequently than an independent stochastic process. This is an exploitable strategy, and we find that this serial correlation negatively affects play efficacy. Our analysis suggests that teams could profit from more clustered play selections, which switch play type less frequently. Our results are consistent with the explanation that teams excessively switch play types in an effort to be perceived as unpredictable.
