Using experimental data, we show that the characteristics of the joint production process have a notable impact on the distribution of bargaining agreements. The setting in which the jointly produced surplus is expressed to be proportional to individual inputs leads to significantly more proportional bargaining agreements. This is in contrast to the setting in which the surplus is expressed as an additive constant, where bargaining agreements are more in line with the Nash bargaining solution.
