CORE DEFINITION

Under information asymmetry, the party with information advantage pays a certain cost (such as peacock's tail, prestigious diploma) to convey a reliable signal about their 'hidden quality' to the party with information disadvantage. Scaffolding role: interpretation of information behind behavior. Explains why advertisements hire celebrities (I have money), job seekers wear formal attire (I am serious). Many seemingly 'irrational' behaviors are actually sending credible signals.

Interpretation of information behind behavior. Explains why advertisements hire celebrities (I have money), job seekers wear formal attire (I am serious). Many seemingly 'irrational' behaviors are actually sending credible signals.

Anchor fast decisions

Same root as signaling: the party with information advantage pays observable costs to convey credible signals about hidden quality to the disadvantaged party. The core of the theory is 'separating equilibrium' - the signal cost must be lower (or the benefit higher) for high-quality types, making it unattractive for low-quality types to imitate. Many seemingly irrational 'burning money' behaviors are actually effective signals.
