In game theory, cheap talk is communication between players that does not directly affect the payoffs of the game. Providing and receiving information is free. This is in contrast to signalling, in which sending certain messages may be costly for the sender depending on the state of the world.
12 giu 2007 · A credible neologism relative to a xed equilibrium exists if there exists a set of types, T, such that precisely types in T prefer R's optimal response to T than the equilibrium payo . If NITS fails, then there is a credible neologism containing t = 0.

1 giu 2002 · The sender's message may be costless (cheap talk) or costly or both. A cheap talk message is defined to be any message that does not affect the sender's (or indeed the receiver's) de facto payoff from any action-type pair (a,t)∈ R ×[0,1].

Costly Signaling: Communication can succeed if talk isn’t cheap. If signals carry costs, then they can credibly reveal information. Examples. I. Sinking costs: Moving an army into position to attack takes resources and is costly. This can reveal a state’s resolve. I. Tying hands: Leader promises citizens that she will not back down to a ...
21 dic 2016 · Cheap-talk models address the question of how much information can be credibly transmitted when communication is direct and costless. When a single informed expert, who is biased, gives advice to a decision maker, only noisy information can be credibly transmitted.
