Substitution and expansion effects in greek agriculture: analysis with a non-parametric approach

Abstract

The substitution and expansion effects in Greek Agriculture, for the period 1970-93 are
analyzed with a recently developed non-parametric approach. The results indicate that the
intermediate inputs are substitutes for land and labor and complements to capital. Labor is
substitute for capital, land is complement to labor and substitute for capital. The substitution
effects outweigh the expansion effects for all inputs but land. The expansion effects work
towards raising the use of labor and land at the expense of capital and intermediate inputs.
