Abstract: Monte-Carlo simulation of nonparametric efficiency shows that even when the number of firms is large, defining ten or more inputs results in most firms being measured as efficient. Comparison of the simulated results with any empirical results may suggest that the dimension of the problem, rather than actual efficiencies, determines computed efficiencies.
