This paper analyzes the interconnections of underreported earnings, savings and oldage pension with the help of a most simple, elementary model. The workers can be divided into three groups: 1) well-paid who report their full earnings, 2) well-paid who report only the minimum earnings (evaders)...

In our model, the government operates a mandatory proportional (contributive) pension system to substitute for the low life-cycle savings of the low-paid myopes. The socially optimal contribution rate is high (equalizing young- and old-age consumption for them), while an appropriate cap on...

Pension systems fight myopia and reduce old-age poverty. Our simple model introduces heterogeneous wages, flexible labor supply, progressive personal income tax and pension credit. The socially optimal transfer system is close to the means-tested one proposed by Feldstein (1987). -- myopia ;...

Nonfinancial defined contribution (NDC) pension systems have recently become popular because they provide the strong incentives of the private funded systems without requiring a difficult transition period. Using the framework of mechanism design, these systems have theoretically been criticized...

The strong and increasing positive correlation between lifetime income and life expectancy (the longevity gap) has recently been widely studied. In this paper we employ the simplest, minimal model to demonstrate the impact of this long-neglected fact on the various types of public pension...
