Signalling games involve one player (the sender) possessing private information that the other player (the receiver) does not have. The sender can then send a signal to the receiver before they both make their decisions. Examples of signalling games include screening games, where the receiver has some power or authority over the sender and they can signal their type or quality to influence the receiver's choice; signalling games, where the sender has some power or influence over the receiver and they can signal their intentions or preferences to affect the receiver's beliefs or actions; and cheap talk games, where the sender can send any signal without cost or consequence, and the receiver can choose whether to believe or ignore it. Examples of these types of games include job interviews, loan applications, product reviews, threats, promises, bluffs, political speeches, sales pitches, and compliments.
