Social security and the interactions between aggregate and idiosyncratic risk
Harenberg, Daniel; Ludwig, Alexander - 2014 - This Version: July 9, 2014
We ask whether a PAYG-financed social security system is welfare improving in an economy with idiosyncratic and aggregate risk. We argue that interactions between the two risks are important for this question. One is a direct interaction in the form of a countercyclical variance of idiosyncratic...

Social security in an analytically tractable overlapping generations model with aggregate and idiosyncratic risk
Harenberg, Daniel; Ludwig, Alexander - 2014 - This Version: September 22, 2014
When markets are incomplete, social security can partially insure against idiosyncratic and aggregate risks. We incorporate both risks into an analytically tractable model with two overlapping generations and demonstrate that they interact over the life-cycle. The interactions appear even though...

Social security in an analytically tractable overlapping generations model with aggregate and idiosyncratic risk
Harenberg, Daniel; Ludwig, Alexander - 2015 - This Version: April 13, 2015
When markets are incomplete, social security can partially insure against idiosyncratic and aggregate risks. We incorporate both risks into an analytically tractable model with two overlapping generations. We derive the equilibrium dynamics in closed form and show that joint presence of both...

Endogenous retirement behavior of heterogeneous households under pension reforms
Börsch-Supan, Axel; Härtl, Klaus; Leite, Duarte; … - 2018 - This draft: 25 April 2018
We propose a unified framework to measure the effects of different reforms of the pension system on retirement ages and macroeconomic indicators in the face of demographic change. A rich overlapping generations (OLG) model is built and endogenous retirement decisions are explicitly modeled...

Fairness of public pensions and old-age poverty
Breyer, Friedrich; Hupfeld, Stefan - 2008
In several OECD countries, public pay-as-you-go financed pension systems have undergone major reforms in which future retirement benefit promises have been scaled down. A consequence of these reforms is that especially in countries with a tight tax-benefit linkage, the retirement benefit claims...
