Measuring scale efficiency from a translog production function

In parametric analysis based on a frontier production function, usually the scale elasticity rather than scale efficiency level is reported. In this p aper we show how one can use an estimated translog production function to o btain output- and input-oriented measures of scale efficiency at an observe d input bundle. We also show how the estimated model can be used to determi ne the optimal quantity of labor input for an exogenously fixed quantity of capital.
