Recent reforms that aim at reducing the upcoming burdens of population ageing might seriously harm low income individuals. An increase in old-age poverty and disability will be the result. Under this prospect, the present paper quantitatively characterizes the optimal progressivity of unfunded...

Like in many other OECD countries, the population will age rapidly in Germany during the next decades. This undermines the future sustainability of the current unfunded public pension system and motivates the search for reform options. The present paper aimes to evaluate some currently discussed...

This study uses Fehr, Jokisch, and Kotlikoff's (2004a) dynamic general equilibrium model to analyze the effects of changes in fertility and mortality on the developed world's demographic transition. The model features three regions - the U.S., Japan, and the EU-15 - and incorporates age- and...

Recent reforms that aim at reducing the upcoming burdens of population ageing might seriously harm low income individuals. An increase in old-age poverty and disability will be the result. Under this prospect, the present paper quantitatively characterizes the optimal progressivity of unfunded...

This chapter examines the micro- and macroeconomic effects of generational policies using closed and open general equilibrium dynamic life-cycle models. The models illustrate the broad array of demographic, economic, and policy issues that can be simultaneously incorporated within todays...

In 2007 Germany has introduced a pension reform which increases the normal retirement age from currently age 65 to 67. The present study aims to quantify the macroeconomic, welfare and efficiency consequences of this reform by means of a computable general equilibrium model with overlapping...

The present paper studies the role of social security in an economy populated by overlapping generations of individuals that have time-consistent or time-inconsistent preferences, face mortality and individual income risk, borrowing constraints as well as progressive income taxes. Our...

In order to stimulate labor market participation and improve the financial viability of the social security systems, many recent reform proposals in various OECD economies suggest to scale down the non-actuarial parts of the pension systems. These reforms have a flavour of increased efficiency...

This paper studies the role of pensions and income taxes in determining homeownership and household wealth. It provides a cross-country analysis, using tax and pension policy designs in Germany, the US and Australia. These developed nations have similar incomes per capita but very different...
