Egalitarian-equivalent Groves mechanisms in the allocation of heterogenous objects

We study the problem of allocating objects when monetary transfers are possible. We are interested in mechanisms that allocate the objects in an e cient way and induce the agents to report their true preferences. Within the class of such mechanisms, rst we characterize egalitarian-equivalent mechanisms. Then, we add a bounded-de cit condition and characterize the corresponding class. Finally, we investigate the relations between egalitarianequivalence and other fairness notions such as no-envy. JEL Classi cations: C79, D61, D63.
