We investigate power abuse of a single punisher in a public-goods-game subject to variations in punishment power and contribution transparency. We nd a high amount of abuse across all conditions. More power led to more abuse over time, while transparency could only curb abuse in the high power conditions. These ndings highlight the dangers of power centralization, but suggest a more complex relation of power and transparency.
