Social objectives in general equilibrium

Shiran Rachmilevitch

Economics Letters, 2016, vol. 148, issue C, 99-102

Abstract: I consider an exchange economy in which each agent’s preferences are given by Ui=ui+θF, where ui is a standard utility function, F is a social objective function and θ is the weight F receives. Both F and θ are common to all individuals. I show that F’s equilibrium value may be a decreasing function of θ. I also show that if F is a social welfare function whose arguments are the ui’s, then the economy’s equilibria are independent of θ.
