This paper reviews three approaches to measuring technical efficiency and presents empirical results using various data sets on Philippine rice farms over the period 1970‐84. First, a production function is estimated using covariance analysis for panel data; second, cross‐section data are used to estimate a stochastic production frontier; and third, a stochastic production frontier is estimated again using panel data. Large ranges of efficiency from the first two methods and a much narrower range from the third are observed. Thus, efficiency measurement is sensitive to methodology, the data period and sample.
