Tournaments are well studied objects in economic theory. Copeland (1951) provides an intuitive way to select alternatives from a tournament, the Copeland set. As a tournament solution, the Copeland set possesses many desirable properties and has been widely studied. Rubinstein (1980) axiomatizes a method to rank alternatives from a tournament which is based on their Copeland scores. This paper analyzes the Copeland set from a revealed preference perspective. A choice procedure where a decision maker has a fixed underlying tournament and selects the Copeland set from every menu is behaviorally characterized.
