Optimal Investigation Strategy for Loss Assessment in Korean Crop Insurance using Mixed Strategy Nash Equilibrium

This study was performed to find out the possibility of compassionate loss assessment and the optimal investigation strategy in Korean crop insurance. For the study, we adopted an approach of Mixed Strategy Nash Equilibrium, one of the equilibrium concept of game theory. Data were obtained from Nonghyup Property & Casualty Insurance in 2012. Results showed that no studies was done to investigate compassionate loss assessment and the insurance company only arbitrarily set a five percentage of investigation among loss assessments. This study analyzed that the optimal investigation rate was about ten to fifty six percent of total loss assessment. Sensitivity analysis showed that the possibility of compassionate loss assessment would be lower as the penalty or compensation suggested by the insurance company were getting larger. These results implied that more strict rules for punishment and efficient investigation process were needed for the sound operation of crop insurance in Korea.
