A sender designs a signal about the state of world to persuade receiver. Under standard assumptions, an optimal censors states on one side cutoff and reveals all other states. This result holds in continuous discrete environments with general monotone partitional signals. The optimally more information if she is biased, certain receiver's preferences, receiver easier persuade. We apply our resu...

Recent works in artificial intelligence fairness attempt to mitigate discrimination by proposing constrained optimization programs that achieve parity for some statistic. Most assume availability of the class label, which is impractical many real-world applications such as precision medicine, actuarial analysis and recidivism prediction. Here we consider longitudinal right-censored environments...

The legal, regulatory, administrative and policing structures of censorship and related forms of information suppression are well known and widely discussed. The much more insidious phenomenon of self-censorship is paid less attention, but it arguably prevents greater volumes of information, argument and comment from being openly expressed. Self-censorship by private individuals might only have...
