Agreeing Now to Agree Later

Résumé du livre

We view a contract as a list of outcomes. Ex ante, the parties commit not to consider outcomes not on the list, i.e., these are ruled out'. Ex post, they freely bargain over outcomes on the list, i.e., the contract specifies no mechanism to structure their choice; in this sense outcomes on the list are not ruled in'. A loose' contract (long list) maximizes flexibility but may interfere with ex ante investment incentives. When these incentives are important enough, the parties may write a tight' contract (short list), even though this leads to ex post inefficiency.
