Principles of Construction and Mathematical Models of the Formation of a Solidarity Fund in an Alternative Old-Age Pension System
The basic principles of the formation of a solidary fund in the suggested old-age pension system are to establish the minimum length of service according to which a citizen has the right to an old-age pension, the implementation into the pension calculation system of the indicator "share deducted to a solidary fund" from each transfer to the personal account of the employee, so that by retirement at the age of 60 and working experience of 38 years, the pension amount was exactly equal to the amount of wages used in calculations. With a decrease in the length of service, the pension amount is reduced according to a certain rule. To implement these principles, appropriate mathematical models have been built that allow to calculate the amount of accumulated pension capital, own pension, accumulated amounts in the solidary fund, the total amount in the pension fund, etc., with any work experience, the amount of wages. Complex calculations were performed using the parameters that have developed in the practice of today. The results of the calculations are presented in tables with the corresponding comments.
