Moral preferences in bargaining

We analyze the equilibrium of a bilateral bargaining game (Nash, 1953, Econometrica, 21: 128–140). where at least one of the individuals has a preference for morality ( homo moralis ). We show that the equilibrium set crucially depends on these moral preferences. Furthermore, our comparative static analyses provide insights into the distributional implications of individuals’ moral concerns and the composition of society. A comparison of the set of equilibria in our model with those under selfish preferences, Kantian equilibrium, fairness preferences, altruistic preferences, and inequality averse preferences reveals important differences.
