Descripción
This study aims to characterise the
evolution of vineyard production, to measure the levels
of technical efficiency, and to relate these with farmers
and farms attributes. The sample used is composed of a
panel of vineyard farms, for the period 2000-2005,
belonging to Portuguese Alentejo region. The
methodology used to estimate technical efficiency, was
the stochastic production frontier.
The results showed that there are room to improve
the levels of technical efficiency in input use and that
efficiency is variant with time. It was observed that
technical efficiency increases with economic size and net
farm income, as well as with family entrepreneurship.
