Technical change in general milk processing is estimated within a homothetic frontier production function allowing neutrally variable scale elasticity. The results show that technical progress is characterized by a rapid increase in optimal scale and a small capital saving bias, increasing the...

This paper is concerned with the measurement of productive efficiency. Farrell's measures of efficiency are generalized to nonhomogeneous production functions. Several new measures of efficiency have been introduced and applied to the Swedish milk processing industry. The empirical analysis is...

A dynamic analysis of structural change is reviewed based on a vintage model of substitutability between inputs including capital before investment, but no substitution possibilities after investment, and ex post production possibilities characterised by fixed input coefficients. Key elements in...
