Recently, compulsory insurance of damage to a third party as a result of accidents caused by vehicles regulations, or in short, third party insurance regulations have been amended by Central Insurance.
Objective: This study compares two new and old third party insurance regulations based on the actuary criterion. First, this article highlights the major differences between the two new and old regulations.
Finding: To achieve this goal, the mathematical form of third-party insurance is rewritten in the form of a bonus-malus system, the steady-state distribution of the bonus-malus system is obtained and in the following, the relativity premium of the new bonus-malus system is calculated by the linear method.
Method: Two third party insurance systems are compared using the steady-state likelihood of systems, the main criterion as Loimaranta efficiency and the relative stability level average.
Conclusion: Based on these comparisons, it can be concluded the following three results:
After examining the timing of the arrival of two new and old bonus-malus systems, it can be concluded that the old system reaches its steady state after 8 years while the new system does not reach its steady state even after 50 years. In other words, the old system has the advantage of achieving steady-state earlier
The premiums provided by the estimated values of the present study are fairer than the premiums offered by the Central Insurance.
Generally, in the new system, the premiums provided by the estimated values of the present study are more efficient than the premiums provided by the central insurance.
All of contents are provided as: In the second part of this study, we compare the old and new third party insurance regulations.Then, in third section, a brief description of the bonus-malus systems and its basic concepts is given, in the following, the mathematical form of the new third party insurance regulations rewritten as a bonus-malus system, then the system's steady-state distribution is calculated and Based on that, the relative premium of the new bonus-malus system is calculated from the linear method. Finally, the two old and new bonus-malus systems are compared using steady-state duration, the loimaranta performance measures, and the mean relative stability level in the fourth section.
