Another Look at the American Electrical Utility Data
The American electric utility data, which are frequently analyzed in the context of frontier models, can be explained by a linear model without inefficiencies. the observed maximum likelihood for this linear model is very mildly smaller than the maximum likelihood for more flexible stochastic frontier models and the log-likelihood-ratio statistic for an approxImate [chi. exp2] test of the simple least squares model against normal exponential and normal-gamma stochastic frontier models is far from significant.
