Explaining bargaining impasse: The role of self-serving biases

The authors review studies conducted by themselves and coauthors that document a 'self-serving' bias in judgments of fairness and demonstrate that the bias is an important cause of impasse in negotiations. They discuss experimental evidence showing that (1) the bias causes impasse; (2) it is possible to reduce impasses by debiasing bargainers; and (3) the bias results from selective evaluation of information. The authors also review results from a field study of negotiations between teachers' unions and school boards in Pennsylvania that both document the fairness bias in a naturalistic setting and demonstrates its impact on strikes.
