An Experimental Study of Bargaining with Low or no Costs of Delay andConstant or Alternating Roles

In this paper we study the robustness of the deadline effect in bargaininggames using constant and slowly decreasing pies, different time horizons,and both constant and alternating role modes. With decreasing pies efficiency requires early agreements while constant pies allow for efficient late agreements. Our results indicate that decreasing pies and alternating roles increase initial generosity and lead to earlier agreements. In addition, conflicts decrease with experience.
