This course mainly surveys the recent developments in Bayesian persuasion and information design. We will begin by briefly covering some classic results of information theory (e.g., Blackwell's "Comparisons of experiments"). We then cover the canonical persuasion model of Kamenica and Gentzkow, and extensions to dynamic and multi-player settings. We might as well cover some behavioral models of persuasion if time permits. Finally we look at certain applications in political economy, consumer markets, matching markets, etc.
