  1. By: Jaume Garcia Villar; María José Suárez
    Abstract: There is a widespread economics literature on the determinants of sports participation and frequency, but the empirical evidence on the robustness of results to changes in the specification assumptions is still scarce. The goal of this paper is to contribute to fill this gap. To this end, we discuss and estimate different models - most of them previously applied in the literature - to check whether the econometric model, the functional form and the definition of physical activity (participation, time, frequency or intensity) condition the results. In particular, we study the probability of exercising, the frequency of participation in the previous week (days of practice), the number of minutes allocated and the intensity of exercise, with different econometric models and functional forms, using a data set from Mexico, where information about these four dimensions of practice of physical activity is available.
    Keywords: sports participation, frequency, time, intensity, econometric modelling

  2. By: Rossi, Martin; Munyo, Ignacio
    Abstract: We exploit a series of natural experiments that use real crime data to investigate the effect of a violation of expectancies on violent crime. We study two types of violation of expectancies that generate the emotions of frustration and euphoria. Our empirical designs exploit differential expectations (as measured by the odds of soccer games in the betting market) while maintaining the outcome unchanged (a loss in a soccer game for frustration, a win in a soccer game for euphoria). We find that frustration is followed by a spike in violent crime whereas euphoria is followed by a reduction in violent crime. The two effects are concentrated in a narrow time window after the end of the game: one hour.
