Mandatory pension systems only partially replace old-age income, therefore the government also operates a voluntary pension system, where savings are matched by government grants. Accounting for the resulting tax expenditure, our models describe the income flow from shortsighted to farsighted...

In his seminal model (Feldstein, 1985), the government operates a social security system to counter the representative worker's myopia. (i) For a complete myope, he determined a sizable optimal tax rate (and the corresponding benefit level). (ii) For a partially shortsighted worker, he...

The dependence of benefit on the retirement age (the schedule) is an important feature in any public pension system. The nonfinancial defined contribution (NDC) pension system has recently become popular mainly because of its allegedly actuarial fairness. Using the framework of mechanism design...

Initial public pensions are indexed to the economy-wide average wages, but pensions in progress are indexed to prices, average wages or their combinations - varying across countries and periods. We create a simple overlapping cohorts framework to study the properties of indexing pensions in...

In this paper, we analyze Hungarian pension policies between 1998 and 2017, comparing the pre- and post-2010 periods. Before 2010, Hungary was a liberal democracy dominated by populist economic policies. We call this the period of democratic populism. After 2010, with center-right but illiberal...

To defend myopic workers against themselves, the government introduces a mandatory system but to help savers, it adds tax-favored retirement accounts. In a very simple model, where benefits are proportional to contributions, we compare three extreme systems: (i) the pure mandatory system, (ii)...

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)...

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...

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...

In our model, the government operates a mandatory proportional pension system to substitute for the low life-cycle savings of the lower-paid myopes, while maintaining the incentives of the higher-paid, far-sighted in contributing to the system. The introduction of an appropriate cap on pension...
