Abstract

Objective: Presenting a model for catastrophe swap pricing based on stochastic models and numerical solution of the model.
Methodology: Descriptive, its design is retrospective, the direction of applied research and the method of collecting information is library. In this research, the "use of available information and documents" tool was used and Varans and Pilke (2009) database was used. In determining the changes in the swap price, Ito's order was followed, and Black and Schulz's generalization of the modeling method was used to reach the catastrophe swap model. A partial integral differential equation was extracted and converted to ordinary differential equations using semi-discretization and finite difference method and Euler method were used to solve the catastrophe swap pricing model. The parameters were estimated and implemented numerically based on Björk's (2009) statistical inference method, and finally, the model was implemented using MATLAB software.
Findings: A new two-factor model for damage has been presented. In other words, instead of C in Anger's model, 〖"Ce"〗^"λ" is used and Landa is considered to change randomly every moment. Therefore, from the point of view of the mathematics of probability, the intensity does not have a fixed value and follows a random geometric Brownian process, which is correlated with the damage. Also, a new model for catastrophe swap pricing has been presented, which has two integral and differential parts.




Conclusion: The catastrophe swap price has an inverse relationship with the growth of damage and the growth of damage severity. Also, the trend of the price for damage less than the threshold has a regular trend, and these changes are proportional to the changes in damage and severity.
