Volatilidade dos retornos econômicos associados à integração lavoura-pecuária no estado do Paraná

In the Brazilian agriculture, there is a great diversity and heterogeneity ofproduction systems that are subject to wide number of factors of risks. Although theserisks cannot be completely eliminated, they can be minimized by adopting somestrategies, as the diversification with agricultural and cattle activities. Based on the research historical results of the Paraná’s agriculture e with the measurement of the value-at-risk, this work aimed to analyze the volatility of the economic returns of integrated crop-beef cattle systems compared to systems characterized by grain cultivation or beef cattle specialization. As results, we observed that, in the short-term, the integrated crop-livestock system is the alternative that trends to generate better economic results.
