      abstract = {This study analyses the regional convergence of the levels  of
labor productivity in the agricultural sector of the  state of Rio Grande
do Sul, through a Markov matrix. It  also examines the variables that
explain this convergence,  through the statistical technique of principal
components  followed by statistical regression. The study is based on  the
data from Agricultural Censuses of the Instituto  Brasileiro de Geografia
e Estatística (IBGE) referring to  the years of 1975 and 1995/96.
The study considers four  classes of levels of labor productivity. The regions
in the  upper class, containing the large cattle raising farms,  show
a tendency to migrate, in the long run, to the lower  classes. The reason
seems to be the reduction in the area  of land available per unit of labor.
The lower class tends  to maintain, in the long run, approximately the
same  percentage of the total regions, which will not evolve in  the level
of labor productivity, maybe because the farms  are too small to get
mechanized, or do not change the  production system to products that
aggregate more value, or  do not adopt technological innovations.},
