Short-run and long-run technical and allocative efficiencies were computed for 395 New York dairy farms using data envelopment or nonparametric procedures on 1990 Dairy Farm Business Summary data. The farms were, on average, more allocatively efficient in the short run than in the long run, but were more technically efficient in the long run than in the short run. Stanchion barns were as effici...

New types of characterization of Pareto efficiency based on data envelopment analysis are extended here in several new directions involving allocative efficiency and stochastic filtering methods.

When building a cross-border transmission line (a so-called interconnector) as a for-profit (merchant) project, where the regulator has required that capacity allocation be done non-discriminatorily by explicit auction, the identity of the investor can affect the profitability of the interconnector project and, once operational, the resulting allocation of its capacity. Specifically, when the i...

The paper gives a brief review of the nonparametric approach to efficiency measurement or Data Envelopment Analysis as it is known in the operations research literature. Inequalities are derived between the efficiency measures when different assumptions are made on the technology sets or on the behavior of managers. Of particular interest is the derivation of a Le Chatelier Principle for measur...

X.efficiency theory challenges the maximization postulate of standard economic theory. This paper shows that X-inefficiency is. at times, as much as 30 times greater than allocative inefficiency and suggests reasons for the existence of X-inefficiency—-i.e., (a) incomplete employment contracts, (b) discretionary effort, and (c) nonmaximization of profits.

We study the effects of allocative and informational externalities in (multi-object) auctions and related mechanisms. Such externalities naturally arise in models that embed auctions in larger economic contexts. In particular, they appear when there is downstream interaction among bidders after the auction has closed. The endogeneity of valuations is the main driving force behind many new, spec...

This paper develops an index of allocative effi ciency that depends upon the distribution of mark-ups across goods and is separable from an index of standard Ricardian gains from trade. It determines how changes in trade frictions affect allocative efficiency in an oligopoly model of international trade, decomposing the effect into the cost-change channel and the price-change channel. Formulas ...

This paper specifies an empirical framework for estimating both technical and allocative efficiency, which is applied to a large panel of European banks over the years 1996 2003. Our methodology allows self-consistent measurement inefficiency, in effort address issue known literature as Greene problem. The results suggest that, on average, exhibit constant returns scale, that efficiency are clo...
