Abstract
This study aims to analyze the technological differences in agricultural production between the municipalities in the semiarid and non-semiarid Northeast Brazil. It uses the technological meta-frontier model proposed by Battese, Rao e O’Donnell (2004), and O’Donnell, Rao e Battese (2008), for responding to what extent these regional differences influence the efficiency of production. It was observed that the hypothesis that the municipalities belonging to the semiarid and non-semiarid face with different production opportunities. The results indicated, that comparing both regions, the non-semiarid region has the highest average technical efficiency with reference to meta-frontier.
