The last two decades have witnessed a revival in interest in the measurement of productive efficiency pioneered by … Farrell technical efficiency in terms of axiomatic production and index number theory in Fare and (1978). These papers have … inspired many others to apply these methods and to add to the debate on how best to define technical efficiency. …

Carlo evidence suggests that the quadratic specification more precisely represents technology. …
