In the arbitration literature there is no common agreement about the nature of the relationship between the size of the contract zone and agreement rates. The results from our experiment show that, when the size of the contract zone increases there are two prevailing effects: one effect is attributed to changes in the range of possible outcomes, and the other to coordination issues. While more room for negotiation leads to higher agreement rates, coordination problems largely impede agreement among rational subjects. The overall effect of an increase in the contract zone depends on the relative magnitude of these opposing effects.
