This paper defines a decomposition of technical efficiency for a series of nonparametric deterministic reference … efficiency decomposition are illustrated with several data sets and contrasted with results based on the traditional, convex Data …

the impact of free trade on welfare and efficiency. First, contrary to the constant elasticity case, in which all gains … illustrate that free trade raises efficiency by reducing the gap between the equilibrium utility and the optimal utility. …

A set of agents with possibly different waiting costs have to receive the same service one after the other. Efficiency … not know agents’ waiting costs, they may have no incentive to reveal them. We identify the only rule satisfying Pareto-efficiency … that even non-single-valued rules satisfy Pareto-efficiency of queues and strategy-proofness if and only if they select …

measures of productive efficiency. Although the methodology is illustrated in terms of technical efficiency measured by output … efficiency scores is assumed to result from variation in empirical approximations to the true boundary of the production set. The … bootstrap procedure also corrects for bias inherent in non parametric efficiency estimators. …

further describe some important features of efficiency by characterizing the efficient distribution (and number) of policies … chosen from the policy space when their cost is small. It turns out that efficiency is achieved when the distribution of …
