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...

Why funding is not a solution to the "social security crisis"
Breyer, Friedrich - 2001
It is now a commonplace that the unfunded public pension systems of many OECD countries will run into severe financing problems in the coming decades due to a dramatically increasing pensioner/worker ratio. While this diagnosis is completely undisputed, there is still a vigorous debate on the...

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...
