A basic function of public pension systems is to guarantee a satisfactory old-age income for short-sighted low earners. In proportional (i.e., earnings-related) systems, this requires a sufficiently high contribution rate. At the same time, there should be a cap on the pension contribution base...

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...

This paper analyzes the effect of public pension system on lifespan and happiness level using optimal longevity model. This paper found the following. Public pension system can make life expectancy longer, however, the extension of lifespan caused by the public pension, not by own decision,...

This paper analyzes the effects of an unfunded pension system on economic growth using an extended overlapping generations model to include the informal sector. Emerging countries usually have a more significant informal sector than advanced ones. The findings based on the Thai economy data...

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)...

A Beveridgean pension scheme invariably introduces a wedge between the wage rate and the marginal take-home pay. A Bismarckian one can do so only if it is not actuarially fair, or in the presence of credit rationing. Interestingly, if the two possible sources of distortion are present at the...

Conventional pension systems suffer from a design defect which makes them financially unsustainable, and a source of inefficiency for the economy as a whole. The paper outlines a second-best policy which includes a public pension system made up of two parallel schemes, a Bismarckian one allowing...

As evidence is accumulating that subjective expectations influence behavior and that these expectations are sometimes biased, it becomes policy-relevant to know how to influence individuals' expectations. Information in the media is likely to affect how people picture the future. This paper...

Pension benefit rules depend on individual history far more than taxes do, and age plays a much larger role in pension determination than in tax determination. Apart from some simulation studies, theoretical studies of optimal tax design typically contain neither a mandatory pension system nor...

This paper examines a static voting model for public pensions. The key premise is that families can internalize the cost and benefits of pay-as-you-go programs. A family realizes a net gain if its members collectively receive more in benefits in the current period than they pay in payroll taxes....
