• Dynamic Privacy Choices

  Staff Working Paper 2022-8 Shota Ichihashi

  Consumers often express concerns about lack of privacy, but they still give up a lot of data to digital platforms. This paper builds a dynamic game-theoretic model of data collection and privacy protection, which potentially explains consumers’ behaviour.

• Online Privacy and Information Disclosure by Consumers

  Staff Working Paper 2019-22 Shota Ichihashi

  A consumer discloses information to a multi-product seller, which learns about the consumer’s preferences, sets prices, and makes product recommendations. While the consumer benefits from accurate product recommendations, the seller may use the information to price discriminate.

• Limiting Sender’s Information in Bayesian Persuasion

  Staff Working Paper 2019-10 Shota Ichihashi

  This paper studies how the outcome of Bayesian persuasion depends on a sender’s information. I study a game in which, prior to the sender’s information disclosure, the designer can restrict the most informative signal that the sender can generate.
