PEREIRA, Marcelo Farid; SILVEIRA, João Serafim Tusi da; LANZER, Edgar Augusto  e  SAMOHYL, Robert Wayne. Productivity growth and technological progress in the Brazilian agricultural sector. Pesqui. Oper. [online]. 2002, vol.22, n.2, pp.133-146. ISSN 0101-7438.

Starting in the 1970's, the Brazilian agricultural sector has experienced an important process of modernization, whose principal effects include advances in technological progress and gains in productivity. The primary objective of this paper is to analyze technological progress and total productivity growth in the Brazilian agricultural sector during the period from 1970 to 1996. The methodology used here is based on the Malmquist productivity index and techniques in mathematical programming called Data Envelopment Analysis. The results show that significant progress was made in this sector of the economy but concentrated in only some regions of the country.

Palavras-chave : total factor productivity; Malmquist index; Brazilian agricultural sector.
