Abstract

This research analyzes a public compulsory crop-credit public insurance program, Proagro Mais, which is one of the largest agricultural risk management programs in Brazil and is also focused on smallholder producers. In particular, this study assesses the influence of the program on the amount of credit obtained per hectare by smallholder corn producers in the state of Paraná, Brazil. The primary dataset is a comprehensive database of agricultural credit borrowers comprising 93.303 individuals. The methodology incorporates the propensity score matching (PSM) at the endline year, employing three distinct matching algorithms, and PSM at the baseline, coupled with the difference-in-differences method. The results indicate that the treatment had ambiguous effect on the treated, with reduced impacts when compared with the outcome variable means. This suggests that the control group may have employed agricultural risk management tools other than Proagro Mais to mitigate the effects of low production on the average credit per hectare. It should be noted that this research represents one of the few impact evaluation studies on crop insurance in Latin America.

Resumo

Resumo: Esta pesquisa analisa o programa público compulsório (com crédito) de seguro agrícola Proagro Mais, que é um dos maiores programas de gestão de risco rural no Brasil, que também é focado nos produtores de pequena escala. Especificamente, foi avaliado o impacto deste programa no valor do crédito obtido por hectare pelos pequenos produtores de milho no Estado do Paraná. O principal componente da informação é um grande banco de dados de mutuários de crédito agrícola composto por 93.303 indivíduos. A metodologia inclui pareamento por escore de propensão (PSM) no ano final (usando três algoritmos de pareamento diferentes) e PSM (na linha de base) juntamente com diferenças em diferenças. Os resultados mostram efeitos ambíguos do tratamento nos indivíduos tratados, porém todos eles com impactos reduzidos quando comparados com as médias da variável de resultado. Isso sugere que o grupo de controle pode ter utilizado outras ferramentas de gestão de risco agrícola além do Proagro Mais para mitigar os efeitos da baixa produção no crédito médio por hectare. Cabe ressaltar que, esta pesquisa é um dos poucos estudos de avaliação de impacto sobre seguro agrícola na América Latina.
