  text: In January 2021, the GameStop stock was the epicenter of the first case of
    predatory trading initiated by retail investors. We use brokerage accounts to
    study who participated in this GameStop frenzy and how they performed. We investigate
    the extent to which investors’ personal and trading characteristics differ from
    the general population of retail investors. GameStop traders had a history of
    investing in speculative instruments, including stocks with lottery-like features.
    They were also more likely to close their positions before the peak of the bubble.
    At the onset of the frenzy, numerous retail investors also shorted GameStop. Overall,
    our results indicate that the GameStop frenzy was not a pure digital protest against
    Wall Street but speculative trading by a group of retail investors, in line with
    their prior high-risk trading behavior.

  text: The containment of COVID-19 critically hinges on individuals’ behavior. We
    investigate how individuals react to variations in COVID-19 reporting. Using a
    survey, we elicit individuals' perceived infection risk given various COVID-19
    metrics (e.g., confirmed cases, reproduction rate, or case-fatality ratio). We
    proxy individuals' risk perception with their willingness to pay for the participation
    in everyday life and amusements events. We find that participants react to different
    COVID-19 metrics with varying sensitivity. We observe a saturation of sensitivity
    for several measures at critical limits used in the political discussion, making
    our results highly relevant for policy makers in their efforts to direct individuals
    to adhere to hygienic etiquette and social distancing guidelines.

  text: We study the relationship between risk managers' dark triad personality traits
    (Machiavellianism, narcissism, and psychopathy) and their selective hedging activities.
    Using a primary survey of 412 professional risk managers, we find that managers
    with dark personality traits are more likely to engage in selective hedging than
    those without. This effect is particularly pronounced for older, male, and less
    experienced risk managers. The effect is also stronger in smaller firms, less
    centralized risk management departments, and family-owned firms.
