This chapter focuses on assessing avocado production index insurances and investigates insurance pricing utilizing credibility theory on a heterogeneous data set. The paper presents a methodology for analyzing and designing insurances, specifically addressing the challenges that arise when dealing with a data sets with varying characteristics. To enhance the reliability of the results, the analysis modifies Bühlmann’s credibility theory to refine parameter distributions. Considering data sets from different countries on avocado production, this chapter provides global and local premium rates for each country, revealing rates based on historical trends. The study also proposes a two-layer policy for insurances that covers production return risks, incorporating both a standard deduction and a preventive measure to mitigate moral hazard risks.
