Anchor fast decisions

The party with an information advantage, to eliminate asymmetry, must proactively send an expensive signal that low-quality parties cannot imitate. Signals are credible only if they are costly (in time, money, or risk), because high-quality senders have lower marginal costs or higher benefits, while low-quality imitators would find it not worth the cost. Essentially, it uses cost to screen types.
