给定一个具有不确定收益的博弈,信息设计分析了仅提供信息就能影响参与者行为的程度。信息设计有一种字面上的解释,在这种解释下,有一个真实的信息设计师,他可以致力于为游戏中的一组参与者选择最佳的信息结构(从她的角度来看)。我们强调一个隐喻的解释,根据信息设计的问题是由分析师在许多不同的信息结构下的游戏的特点。我们提供了一个介绍信息设计中快速增长的文献的基本问题和见解。我们展示了信息设计的字面和隐喻解释如何统一了大量现有的工作,包括游戏中的沟通(Myerson 1991),贝叶斯说服(Kamenica和Gentzkow 2011),以及我们自己最近在不完全信息游戏中的鲁棒预测方面的一些工作。(JEL C70、D82、D83)
Given a game with uncertain payoffs, information design analyzes the extent to which the provision of information alone can influence the behavior of the players. Information design has a literal interpretation, under which there is a real information designer who can commit to the choice of the best information structure (from her perspective) for a set of participants in a game. We emphasize a metaphorical interpretation, under which the information design problem is used by the analyst to characterize play in the game under many different information structures. We provide an introduction to the basic issues and insights of a rapidly growing literature in information design. We show how the literal and metaphorical interpretations of information design unify a large body of existing work, including that on communication in games (Myerson 1991), Bayesian persuasion (Kamenica and Gentzkow 2011), and some of our own recent work on robust predictions in games of incomplete information.
