Credibility, Efficiency and the Structure of Authority

Résumé

In many economic settings it is optimal to endow individuals with high abilities, rather than those with low abilities, with decision-making power. Yet there is rich empirical evidence showing that many of those in charge of decisions are not necessarily the most talented. We offer a novel rationale for why choosing a decision maker with low ability might be welfare-optimal. In a setting with two-sided information acquisition where the players disagree only when uninformed, we show that a high-ability principal optimally delegates authority toa low-ability agent because the latter not only exerts higher effort than under centralized decision-making, but also follows the principal’s advice when uninformed himself. joint with Dimitri Migrow .
