Risk Aversion and Network Exchange: Experimantal Evidence on Nash-Bargaining with Heterogeneous Risk Preferences
4 May 2017, 15.15 - 16.45
IWF A 34 (Haldeneggsteig 4)

Exchange theories often explain exchange outcomes as the result of bilateral bargaining on the distribution of a perfectly divisible surplus. Howeiver, they neglect interindividual heterogeneity in favor of the effects the given network structure has for exchange outcomes.
We propose a model of proft splits in bilateral bargaining which combines the generalized Nash bargaining solution from cooperative game theory with the assumption that network positions affect the individual bargaining powers in a specific way. To address the aspect of interindividual heterogeneity, we relax the assumption that the structure alone explains negotiation outcomes to also allow - in a first step - for the influence of individual risk preferences. Experimental empirical evidence shows that risk aversion may not influence the negatiation outcomes but the development of offers and counteroffers in the course of bargaining.
