We model the optimal reaction of a public PAYG pension system to demographic shocks. We compare the ex-ante first best and second best solution of a Ramsey planner with full commitment to the outcome under simple third best rules that mimic the pension systems observed in the real world. The...

In this paper, I estimate the fiscal impact of immigrants on the German pension insurance (PI) and unemployment insurance (UI) systems when return migration is an endogenous choice. For this purpose, I develop a dynamic stochastic model of joint return migration and saving decisions that...

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,...

Conventional pension systems suffer from a design defect which makes them financially unsustainable, and a source of inefficiency for the economy as a whole. The paper outlines a second-best policy which includes a public pension system made up of two parallel schemes, a Bismarckian one allowing...

In Germany, there is an ongoing debate about how to increase the efficiency of the social security system and especially its financing. The aim of this paper is to simulate different financing systems for Germany. The introduction of a Liberal British or the Southern Greek financing system...

This paper analyzes the effectiveness of occupational training programs for the unemployed before and after the substantial amendments in German labor market legislation known as Hartz reforms. Based on the official evaluation of the reforms, we show that program impacts vary much across...

The German government provides discretionary investment grants to structurally weak regions to reduce regional disparities. We use a regression discontinuity design that exploits an exogenous discrete jump in the probability of receiving investment grants, to identify the causal effects of the...

Populous communities often prefer more government involvement than less populous communities, but does community size per se affect citizens' preferences for government? Endogeneity commonly prevents testing for causal effects because (i) people can select into communities while (ii) government...

Measures of subjective well-being have gained substantial attention in economics as quantitative approximations of individual welfare. They allow researchers to study relevant determinants of welfare on an individual as well as on a societal level. These determinants might not to be easily...

Tradable black (CO2) and green (renewables) quotas gain in popularity and stringency within climate policies of many OECD countries. The overlapping regulation through both instruments, however, may have important adverse economic implications. Based on stylized theoretical analysis and...
