IMPORTÂNCIA DAS ATITUDES DOS AGRICULTORES AO RISCO DE DECI· SÕES DE PRODUÇÃO
Elmar Rodrigues da Cruz
Resumo
O tema principal deste trabalho é mostrar que risco não deve ser tomado como o único fator que explica as discrepâncias entre os níveis economicamente ótimos de insumos e os níveis realmente usados. Após a apresentação do modelo conceituai, é introduzido o conceito de função de resposta esperada, estimada através de uma abord_agem subjetiva, a qual permite estimar-se para cada agricultor da amostra os níveis economicamente ótimos de fertilizantes, que são então comparados com os níveis realmente usados. Conclui-se que as discrepâncias resultantes destas comparações não são adequadamente explicadas pelo fator risco, e sugere-se então a possibilidade de outros fatores estarem presentes nas tomadas de decisões dos agricultores.
