    Abstract: We report an experiment to consider the emotional correlates of prudent decision making. In the experiment, we present subjects with lotteries and measure their emotional response with facial recognition software. They then make binary choices between risky lotteries that distinguish prudent from imprudent individuals. They also perform tasks to measure their cognitive ability and a number of personality characteristics. We find that a more negative emotional state correlates with greater prudence. Higher cognitive ability and less conscientiousness is also associated with greater prudence.

    Abstract: This paper investigates the time series properties of fighting and scoring in the National Hockey League from 1957-2013. The empirical analysis focuses on identifying structural breaks in the various time series and correlating these breaks with rule changes in the NHL, especially those that focus on fighting. We find that player behavior in the areas of fighting and scoring changed structurally before rule changes in the NHL that reduced the benefits and increased the costs of fighting. The data and empirical results suggest that the rise and fall of the enforcer was a function of changes in social norms within the NHL rather than legal changes by the league itself. The example suggests that other sports might also experience changes in social norms that lead to reduced violence and increased offense before formal rule changes are made by league officials. Key Words: Social Norms, Cultural Change, Rule Changes, Structural Breaks

  3. By: Boris Gershman; Diego Rivera
    Abstract: This paper compares two approaches to measuring subnational ethnolinguistic diversity in Sub-Saharan Africa, one based on censuses and large-scale population surveys and the other relying on the use of geographic information systems (GIS). The two approaches yield sets of regional fractionalization indices that are moderately positively correlated, with a stronger association across rural areas. These differences matter for empirical analysis: in a common sample of regions, survey-based indices of deep-rooted diversity are much more strongly negatively associated with a range of development indicators relative to their highest-quality GIS-based counterparts.
