| Outline of Final Research Achievements |
We examine three tools that can enhance coordination success in a repeated multiple-choice coordination game. Gradualism means that the game starts as an easy coordination problem and moves gradually to a more difficult one. The Endogenous Ascending mechanism implies that a gradual increase in the upper bound of coordination occurs only if coordination with the Pareto superior equilibrium in a stage game is attained. The Endogenous Descending mechanism requires that when the game’s participants fail to coordinate, the level of the next coordination game be adjusted such that the game becomes simpler. Our laboratory experiment proves that a mechanism that combines these three tools, herein termed the “Gradualism-Endogenous Ascending-Endogenous Descending (GEAD)” mechanism, works well.
