A forma flexível de Fourier, a estimação de elasticidades e vieses tecnológicos para a agricultura brasileira
João Lopes de Albuquerque Montenegro; Geraldo da Silva e Souza
Resumo
Ajusta-se um sistema de dispêndios do tipo flexível de Fourier aos dados agregados da agricultura brasileira no período de 1950 a 1980. Estimam-se elasticidades de substituição, elasticidades de preços e vieses tecno16gicos. O modelo utilizado conduz à rejeição da hip6tese de uma tec- nologia de produção do tipo Translog. Todas as elasticidades variam signifi- cativamente no período, e a magnitude dos vieses tecnológicos indicam uma economia essencialmente neutra.em termos de trabalho e terra, e intensiva no uso de fertilizantes e máquinas.
