This paper incorporates quasi-hyperbolic discounting into a Mirrlees taxation model to study the design of retirement policies for present-biased agents. I show that the government can improve the screening of productivity by exploiting time inconsistency. This is done by providing commitment to...

The natural interest rate is the level of the real interest rate compatible with potential output and stable prices. We develop a life-cycle model and calibrate it to the US economy to quantify the role of the public pension scheme for the past and future evolution of the natural interest rate....

Many countries, in an effort to address the problem that too many retirees have too little saved up, impose mandatory contributions into retirement accounts, that too, in an age-independent manner. This is puzzling because such funded pension schemes effectively mandate the young, who wish to...

Der vorliegende Referentenentwurf zum Rentenpaket II sieht neben einer Verlängerung der Haltelinie zur Stabilisierung des Rentenniveaus die Errichtung einer Stiftung "Generationenkapital" vor. Der Entwurf strebt dabei den Aufbau eines Stiftungsvermögens von 200 Mrd. Euro und jährliche...

In this paper, we develop a dynamic politico-economic theory of social security to address two questions. First, how is social security sustained? Second, how does inequality affect the size of social security, and can the theoretical predictions be consistent with the observed puzzling...

Since the 2008 global financial crisis, those East European countries that had partly privatized their pension systems in the 1990s or early 2000s increasingly scaled back their mandatory private retirement accounts and restored the role of public provision. What explains this wave of reversals...

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 revisits the role played by myopia in generating a theoretical rationale for pay-as-you-go social security in dynamically efficient economies. Contrary to received wisdom, if the real interest rate is exogenously fixed, enough myopia may justify public pensions but never alongside...

We consider a two-period overlapping generations model in which individual voters differ by age and by productivity. In such a setting, a redistributive Pay-As-You-Go system is politically sustainable, even when the interest rate is larger than the rate of population growth. The workers with...

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...
