It is conventional wisdom that transparency in cartels– monitoring of competitors’ prices, sales, and profits– facilitates collusion. However, in several recent cases cartels have instead gone out of their way to preserve the privacy of their participants’actions and outcomes. Towards explaining this behavior, we show that cartels can sometimes sustain higher profits when actions and outcomes a...

Saving On-Line Privacy

With the increasing use of electronic media for our daily transactions, we widely distribute our personal information. Once released, controlling the dispersal of these information is virtually impossible. Privacy-enhancing technologies can help to minimize the amount of information that needs to be revealed in transactions, on the one hand, and to limit the dispersal, on the other hand. Unfort...

Maintaining Privacy During Psychosocial Research on the International Space Station

Preserving privacy whilst maintaining robust epidemiological predictions.

Mathematical models are invaluable tools for quantifying potential epidemics and devising optimal control strategies in case of an outbreak. State-of-the-art models increasingly require detailed individual farm-based and sensitive data, which may not be available due to either lack of capacity for data collection or privacy concerns. However, in many situations, aggregated data are available fo...

Maintaining Data Privacy in Association Rule Mining

We investigate here, with respect to mining association rules, whether users can be encouraged to provide correct information by ensuring that the mining process cannot, with any reasonable degree of certainty, violate their privacy. We p...
