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...

We provide new evidence of forward-looking labor supply responses to changes in pension wealth. We exploit a 2014 German reform that increased pension wealth for mothers by an average of 4.4% per child born before January 1, 1992. Using administrative data on the universe of working histories,...

Social security programs generally seek to provide insurance and to reduce poverty and inequality. Providing insurance requires little redistribution. But reducing inequality and alleviating poverty do require redistribution. To reduce inequality, programs must redistribute income, but...

We study retirement incentives with augmented option value model à la Stock and Wise (1990). We propose methodological extensions to better reflect the respective incentives faced by singles and couples. Our results show that a more comprehensive modelling of couples' incentives leads to very...

There exists a wide variety of tax treatments of pensions across the world. And the reasons for such a range of regimes are not clear. This note reviews the general principles of pension taxes and analyses the theoretical foundations of why pension incomes ought to be taxed specifically. To do...
