Os empregados da agricultura brasileira: diferenciais e determinantes salariais

This work studies the wage differentials and determinants ofthe employees in Brazilian agriculture, in period 1981-2005, on the basisof the information of the National Research for Sample of Domicilesof the IBGE. The methodology of Heckman is used to correct bias ofselection, common in wage equations gotten by Least Ordinary Square,besides the decomposition of Oaxaca-Blinder, to analyze the wagedifferentials between 1981 and 2005. Between wage determinants, hadbeen analyzed: education, experience, region, weekly working time andformal work, besides some macroeconomic determinants. The resultsof the work suggest a reduction of the wage differentials, mainly inthe end of the studied period, and that the variable education, age andformal work had contributed to reduce the wage differentials between1981 and 2005; and on the other hand, the variable geographic regionand weekly working time, had contributed to increase them. Moreover,the macroeconomic variables included in the analysis were statisticalsignificant in the explanation of the agricultural differentials.
