In this paper we present a methodology to analyse input use in the agricultural
sector. The novelty of the
theoretical model explained is that it has been developed considering a multi-criteria
environment. Thus, the
optimal input use condition is determined by the assessment of "multi-attribute utility"
and "multi-attribute
marginal utility". We show how the approach adopted in this paper is a generalization
of the single-attribute
expected utility theory. The theoretical model developed is further implemented in
an empirical application
that studies water for irrigation use as a particular case. Results show how multi-attribute
utility functions
elicited for a sample of 52 irrigators explain differences on irrigation
water use in relative homogenous
agricultural systems, albeit exhibiting similar water partial utility functions.
We conclude that these
differences come from the dissimilar weights that farmers attached to each attribute
in the aggregate utility
function. The irrigated area considered as case study is located in North-western
Spain.
