Abstract
This paper aims to measure and compare technical efficiencies in the England and Wales dairy sector from stochastic production functions in the immediate post‐quota period. Milk Marketing Board data for a stratified random sample of dairy farms for 1984/85, 1985/86 and 1986/87 are used. The results show that average levels of efficiency have initially fallen and then stabilized over this period. Moreover, there is a high degree of correlation between the rankings of the efficiency measures.
