This paper describes empirical research into the privacy preferences and behaviors of individuals regarding personalization in music recommender systems. These phenomena concern music recommendations based on two different types of user information: preferences for music genres and personality traits. Our results indicate similar disclosure behavior by users for both types of personal informati...

This paper presents a study of obfuscation practices in location-sharing systems. The study shows that users have relatively complex preferences that depend on the recipient of the location, the time of the request and location. The preferences also require multiple levels of obfuscation (ranging from disclosing no location information to disclosing the exact location) to accurately capture. Fo...

Predicting survival and disclosing the prediction to patients with advanced disease, particularly cancer, is among the most difficult tasks that physicians face. With the de-emphasis of prognosis in favor of diagnosis and therapeutics in the medical literature, physicians may have difficulty finding the survival information they need to make appropriate estimates of survival for patients who de...

Recently, researchers have proposed decision support tool for generating suggestions for bids in combinatorial reverse auction based on disclosure of bids. An interesting issue is to design an effective mechanism to guide the bidders to collectively minimize the overall cost without explicitly disclosing the bids. We consider a winner determination problem for combinatorial reverse auction and ...

We study the joint delegation of operating and disclosure choices in a multiprincipal agent setting. We find that joint delegation alters both the incentives to deviate from profit– maximizing operating choices and disclosure policy adoption choices. Incentive weights on revenues are greater for the firm with greater ex ante cost uncertainty, greater expected market size and greater expected pr...
