Abstract

This paper deals with the role of public research in Italian agriculture during the period 1960--1995. A short-run Generalised Leontief cost function capable of accommodating quasi-fixed factors and variable returns is used. Temporary equilibrium and scale economies are investigated with special emphasis on the methodological implications of R&D stock and the consistency of the estimated model with microeconomic theory. Comparing the relevant shadow and rental price provides evidence on under- (over)-investment and the rationale driving public research expenditure in agriculture. A formal test of the induced innovation hypothesis and the calculation of the internal rate of returns are also presented. Copyright 2003, Oxford University Press.
