Agricultural insurance is one of the appropriate ways to overcome the risk in agricultural production and to increase farmers’ income security. In this study, the influence of wheat insurance, as personal-free insurance, and sugar beet insurance, as group-forcible insurance, on farmers’ risk attitudes in Fars Province were investigated as a case study. Data were collected using stratified multi...
The main objective of the present study is to analyze the effects of agricultural crop insurance on farmers’ technical efficiency and risk attitude. Required data came from questionnaires that were completed by the Institute for Planning and Agricultural Economics of the Ministry of Agriculture. Farmers’ technical efficiency and attitude toward risk were estimated using stochastic frontier prod...

This paper generalizes the notion of risk aversion for functions which are not necessarily differentiable nor strictly concave. Using an approach based on superdifferentials, we define the notion of a risk aversion measure, from which the classical absolute as well as relative risk aversion follows as a RadonNikodym derivative if it exists. Using this notion, we are able to compare risk aversio...

In a preceding paper (Montesano, 1999b) a systematic set of definitions on risk and uncertainty aversion was introduced with regard to unidimensional lotteries and acts. Taking into account only the preference preordering over the set of all possible lotteries and acts represented by the certainty equivalent function, many propositions were introduced and demostrated on global and local risk an...
In this paper we reply to Binmore and Shaked’s criticism of the Fehr-Schmidt model of inequity aversion. We put the theory and their arguments into perspective and show that their criticism is not substantiated. Finally, we briefly comment on the main challenges for future research on social preferences.
