Resumo: Several studies argue that agricultural mechanization has reduced employment and wages. However, there is a lack of studies analyzing employment and income over time, especially comparing the agricultural activities. Our major argument is the structural change in the employment - from un-skilled to skilled workers which has to be understood because of the overall decrease in the number of jobs. This study aims to analyze the labor market evolution in sugarcane farming and other agricultural activities, from 1992 to 2015. Using the National Household Sample Survey (PNAD/IBGE), we compared sugarcane and other Brazilian crops using econometrics techniques. We analyzed the Heckman's procedure and models with fixed effects panel data, controlling the unobservable characteristics of workers. Methodologically, our equations show convergence, since the Heckman procedure and pooled regression present similar estimates. We showed that fixed- effect regression captures the same trends of Ordinary Least Square (OLS) technique, using the Heckman method. Our main findings suggest that the wage of sugarcane workers is higher than wages in other crops, even after we control the observable and regional characteristics. This finding is important because the sugarcane sector has faced criticism regarding the low level of employment and income due to the mechanization process. Finally, we pointed out the decrease in unskilled jobs in sugarcane, which demands for policy intervention to improve the human capital in the sugarcane sector.

No entanto, faltam estudos que analisem o emprego e a renda ao longo do tempo, principalmente comparando as atividades agrícolas. O argumento apresentado por este artigo é que a mudança estrutural no emprego - de trabalhadores não qualificados para qualificados, deve ser entendida por causa da diminuição geral do número de empregos. Este estudo tem como objetivo analisar a evolução do mercado de trabalho na lavoura canavieira e demais atividades agrícolas, de 1992 a 2015. Por meio da Pesquisa Nacional por Amostra de Domicílios (PNAD / IBGE), este artigo compara a cultura da cana-de-açúcar com outras lavouras brasileiras por meio de técnicas econométricas. Analisamos o procedimento e os modelos de Heckman com dados de painel de efeitos fixos, controlando as características não observáveis dos trabalhadores. Metodologicamente, nossas equações mostram convergência, uma vez que o procedimento de Heckman e a regressão combinada apresentam estimativas semelhantes. Note que a regressão de efeito fixo captura as mesmas tendências da técnica de Mínimos Quadrados Ordinários (MQO), usando o método de Heckman. Os principais resultados sugerem que o salário dos trabalhadores da cana-de-açúcar é maior do que o salário de outras safras, mesmo depois de controlar as características observáveis e regionais. Essa constatação é importante porque o setor sucroalcooleiro tem enfrentado críticas quanto ao baixo nível de emprego e renda devido ao processo de mecanização. Por fim, destacamos a diminuição do número de empregos não qualificados na cana-de-açúcar, o que exige intervenção de políticas para a melhora do capital humano no setor sucroalcooleiro.2022-06-13T20:26:22Z2022-06-13T20:26:22Z2021info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfFERRAZ, D. et al.
