Choosing Between Hail Insurance and Anti-Hail Nets: A Simple Model and a Simulation among Apples Producers in South Tyrol

There is a growing interest in analysing the diusion of agricultural insurance, seen as an eective tool for managing farm risks. Much atten- tion has been dedicated to understanding the scarce adoption rate despite high levels of subsidization and policy support. In this paper, we anal- yse an aspect that seems to have been partially overlooked: the potential competing nature between insurance and other risk management tools. We consider hail as a single source weather shock and analyse the po- tential competing eect of anti-hail nets over insurance as instruments to cope with this shock by presenting a simple theoretical model that is rooted into expected utility theory. After describing the basic model, we perform some comparative static analysis to identify the role of individual elements that are shaping farmers' decisions. From this exercise it results that the worth of anti-hail nets compared to insurance is an increasing function of the overall risk of hail damages, of the farmers' level of risk aversion and of the worth of the agricultural output. Finally, we develop a simulation model using data related to apple pro- duction in South Tyrol, a Northern-Italian province with a relatively high risk of hail. The model generally conrms the results of the comparative static analysis and it shows that, in this region, anti-hail nets are often superior than insurance in expected utility terms.
