Abstract
Despite a specific law obligation to insure at least 50% of the areas, only about 11% of the farmers
insure crop. Such a low percentage of insurance raises the question of the reality of the stabilizing effect of
crop insurance on income. In order to answer this question in the study the impact of crop insurance on the
variance of gross value added in the farm was investigated. Based on a sample of 590 households, it was
found that, such an effect exist only in the case of holdings specializing in crop production. Additionally, the
importance of an adequate regression model, depending on the response variable distribution and sampling
methods was shown.
