Intra-firm bargaining under non-binding contracts

We present a new methodology for studying the problem of intra-firm bargaining, based on the notion that contracts cannot commit the firm and its agents to wages and employment. We develop and analyse a general non-cooperative multilateral bargaining framework between the firm and its employees and consider outcomes which are immune to renegotiations by any party. Equilibrium firm profits are characterizable as both a weighted average of a neo-classical (non-bargaining) firm's profits and a generalization of Shapley value for a corresponding cooperative game. Furthermore, the resulting payoffs induce economically significant distortions in the firm's input and organizational-design decisions.
