This paper studies a model of mechanism design with transfers where agents' preferences need not be quasilinear. In such a model, (1) we characterize dominant strategy incentive compatible mechanisms using a monotonicity property; (2) we establish a revenue uniqueness result: for every dominant...

Let X be a connected metric space, let N be the set of natural numbers, and let be a preference order defined on a suitable subset of X^N. I characterize when has a Cesàro average utility representation. This means that there is a continuous function u from X into the real numbers, such that...
