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...

This paper examines the effect of the introduction of permanent benefit reductions for early retirees (i) on the duration until retirement entry and (ii) on the duration until exit from gainful employment. I estimate discrete time duration models using different error term specifications....

This study identifies the causal effect of pension generosity on women's fertility behavior. It capitalizes on Brazil's expansion of the pension system to rural workers, whose pension wealth subsequently more than tripled. Event study, difference-in-differences and instrumental variable methods...

We investigate the responsiveness of individual retirement decisions to changes in financial incentives. The causal effect is identified based on the natural experiment generated by an institutional reform. The results of a binary retirement model are robust to alternative model specifications,...

The present paper aims to quantify the macroeconomic and welfare effects of taxfavored retirement accounts. Starting from an equilibrium without saving incentives, we introduce such accounts and compute the new transition path and the resulting long-run equilibrium. Since our...

We use reforms in the Swiss public retirement system to identify the responsiveness of retirement timing to financial incentives. A permanent reduction of retirement benefits by 3.4 percent induces more than 70 percent of females to postpone their retirement. The responsiveness of male workers,...

We study causal effects of two early retirement reforms. Reform 1 (NRA) increased normal retirement age stepwise from 60 to 63. Simultaneously, it became possible to use early retirement with benefit discounts. Reform 2 (ERA) increased the age of early retirement stepwise from 60 to 63. We...

We propose exible models for multivariate realized volatility dynamics which involve generalizations of the Box-Cox transform to the matrix case. The matrix Box-Cox model of realized covariances (MBC-RCov) is based on transformations of the covariance matrix eigenvalues, while for the Box-Cox...

Many European countries are currently transferring their pay-as-you-go public pension system to a three-pillar-system of public, occupational, and private pensions. In Germany, economists expect a pension gap for future retiree cohorts as public pensions will decrease and private old age...
