In an intensively discussed paper, Andreoni and Sprenger (2012) , henceforth A&S, present an experiment where subjects can allocate money between two different points of time under the condition of risk. A&S claim that their results refute discounted expected utility (DEU) as well as prospect...

Banks should evaluate whether a borrower is likely to default. The author applies several techniques in the extensive mathematical literature of stochastic optimal control/dynamic programming to derive an optimal debt in an environment where there are risks on both the asset and liabilities...

Germany'’s social security system is surveyed, its benefits and contributions are discussed. The expansion of this system in the last decades is described, its impact on employment and growth is studied and proposals for the reform of the system are discussed.

In order to face the aging of their populations governments of developed countries reformed their retirement systems during the last two decades, by discouraging early retirement and increasing incentives to work for older workers. Senior participation rates to the labor force not only differ...

This paper develops a simple analytical framework in which optimal health and retirement policies amid population aging can be discussed. To be efficient, these policies must recognize and exploit the dynamic complementarities between the timing of retirement, the size of lifecycle labour income...

This paper examines the role of the health gradient ; the positive correlation between household income and health – in individual retirement behavior, using data from the German Socio-economic Panel (GSOEP). We first estimate agegroup-specific health gradients and find their slope increases...

This paper studies the evolution of early retirement due to disease and injury in the German labor force between 1988 and 2004. Using data from the German Federation of Public Pension Providers, the IMS Health Drug Launches database and the WHO Mortality Database, we show that new drug launches...

In this paper we analyze theoretically and empirically the impact of an increase in income inequality on the current account balance. We develop a model with consumption externalities and heterogeneous agents which explains how an increase in income inequality can affect negatively or positively...

Aphorisms that "Rising tides raise all boats" or that material advances of the rich eventually "Trickle Down" to the poor are really maxims regarding the nature of stochastic processes that underlay the income/wellbeing paths of groups of individuals. This paper looks at the implications for the...

We construct a Blanchard-style overlapping generations model consisting of long-lived individuals who have uninsurable idiosyncratic risk resulting from uncertain retirement periods and medical costs in retirement. Without social insurance, such individuals must save for these eventualities. We...
