We develop a nonparametric test of productive efficiency that accounts for the
possibility of errors-in-variables. The test allows for statistical inference based on the
extreme value distribution of the L?? norm. In contrast to the test proposed by Varian,
H (1985): 'Nonparametric Analysis of Optimising Behaviour with Measurement
Error, Journal of Econometrics 30, 445-458, our test can be computed using simple
enumeration algorithms or linear programming. An empirical application for the
Dutch electricity sector illustrates the proposed test procedure
