We study the question of which social choice functions from an abstract type space to a set of outcomes are truthful, i.e., implementable by truthful mechanisms, when utilities are quasi-linear. For convex domains, our main theorem characterizes truthful social choice functions as those...

We consider the joint pricing and inventory problem of a capacity constrained service facility with several classes of customers. The customers are differentiated with their sensitivity for waiting and their willingness to pay for the service. We model the problem using an M/M/1 queueing system...

This paper studies optimal education policies under endogenous borrowing constraints in a standard life-cycle model. In a closed economy, a policy that appropriately bundles an education subsidy with an old-age pension can restore the complete market allocation. Such a policy also removes...

We characterize the efficiency space of deterministic, dominant-strategy incentive compatible, individually rational and Pareto-optimal combinatorial auctions in a model with two players and k nonidentical items. We examine a model with multidimensional types, private values and quasilinear...
