An Index of Competitiveness and Cooperativeness for Normal-Form Games†

An Index of Competitiveness and Cooperativeness for Normal-Form Games† AbstractWe develop an index of competitiveness and cooperativeness that is based on the primitives of a normal-form game, i.e., players, strategies and payoffs. The index relies on the unique decomposition of a given game into a zero-sum game and a common interest game. The index decreases in the distance to its zero-sum part and increases in common interest part. The comparative statics of our index coincide with economic intuition. The index also supports experimental findings in well-known classes of games in the sense that more cooperative and less competitive behavior correlates with lower values of the index.
