This paper proposes a new method for welfare analysis of unfunded social security systems. Based on an overlapping generations model with endogenous labor supply, we derive a formula for the evaluation of existing pay-as-you-go social security systems that depends on impulse response functions...

This paper proposes a method for the welfare analysis of pay-as-you-go social security systems. We derive a formula for the welfare consequences of a permanent marginal change in the payroll tax rate that is valid under weak assumptions about the deep structure of the economy. Our approach...

The macroeconomic implications of firms' lumpy investment behavior are subject to ongoing research. Lumpy investment results from fixed capital adjustment costs which give firms an incentive to reduce the frequency of capital adjustments. However, previous studies have underestimated the...

This paper analyzes estimators based on the instrumental variable quantile regression (IVQR) model (Chernozhukov and Hansen, 2004, 2005, 2006) under the local quantile treatment effects (LQTE) framework (Abadie et al., 2002). I show that the quantile treatment effect (QTE) estimators in the IVQR...

This paper studies estimation of conditional and unconditional quantile treatment effects based on the instrumental variable quantile regression (IVQR) model (Chernozhukov and Hansen, 2004, 2005, 2006). I introduce a class of semiparametric plug-in estimators based on closed form solutions...

The extent to which exchange rate fluctuations are passed through to domestic prices is of high relevance for open economies and for monetary authorities targeting price stability. Existing empirical studies estimating the exchange rate pass-through for Switzerland are based on either single...

Sudden stops in capital inflows were a main characteristic of the emerging market crisis during the 1990's. Concerns about them have recurred in the light of recently increased global stability risk and the quantitative easing that led to substantial capital inflows in emerging economies. We add...

We estimate the impact of external financial support on the labor supply of students during their tertiary education. Using dynamic labor supply models and accounting for the endogeneity of transfer income and academic performance, we find a significantly smaller likelihood of working for...

Die Grünen wollen das Klima und die Umwelt schützen. Was tun sie, wenn sie Regierungsverantwortung innehaben? Anhand der ersten grün-geführten Landesregierung in Baden-Württemberg wird untersucht, wie eine grün-geführte Regierung Umweltziele, wie CO2-Emissionen, und andere Zielgrößen,...
