摘要：Since 2003 crop insurance programs became the focus of agricultural policy in Brazil. Given the increasing interest in insurance, accurate calculation of premium values is of great importance. We address the issue of the revenue distribution at the farm-level and its implication to the Brazilian crop insurance contract. We estimate the probability of loss by using the Skew-normal distribution of revenue in the West of Parana (South of Brazil). Results show that insurers (empirical) rates tend to underestimate the risk in the lower coverage levels (50% and 60%). At the level of 70% of coverage the Empirical Rate and the Skew-Normal Rate are similar on average.
