Computer program calculating our non-dictatorship index for the respective voting rules.

The data are provided by the Recommendation Team at Microsoft Research and include information on historical purchases of applications from the Microsoft store. The training set includes a random sample of 1000 users. For each user, data include variables indicating whether she has or has not bought an item in a specific game category (e.g., 'role-playing' or 'music')..

Theories of decision-making are routinely based on the notion that decision-makers choose alternatives which align with their underlying preferences – and hence that their preferences can be inferred from their choices. In some situations, however, a decision-maker may wish to hide his or her preferences from an onlooker. This dataset contains the results of an obfuscation game that was designed to explore whether decision-makers, when properly incentivized, would be able to obfuscate effectively, and which heuristics they employ to do so.
