We explore voluntary participation in pension arrangements. Individuals only participate when participation is more attractive than autarky. The benefit of participation is that risks can be shared with future generations. We apply our analysis to a pay-as-you-go system, a funded system without...

We investigate intergenerational risk sharing in two-pillar pension systems with a pay-as-you-go pillar and a funded pillar. We consider shocks in productivity, depreciation of capital and inflation. The funded pension pillar can be either defined contribution or defined benefit, with benefits...

We explore intergenerational and international risk sharing in a general equilibrium multiple-country model with two-tier pensions systems. The exact design of the funded tier is key for the way in which risks are shared over the various generations. The laissez-faire market solution fails to...

We explore the feasibility of a funded pension system with intergenerational risk sharing when participation in the system is voluntary. Typically, the willingness of the young to participate depends on their belief about the future young's willingness to do so. We characterise equilibria with...

Based on well-known evidence on labor supply elasticities, several authors have concluded that women should be taxed at lower rates than men. We evaluate the quantitative implications of taxing women at a lower rate than men. Relative to the current system of taxation, setting a proportional tax...

Using real-time data from Europe's Stability and Convergence Programs, we explore how fiscal plans and their implementation in the EU are determined. We find that (1) implemented budgetary adjustment falls systematically short of planned adjustment and this shortfall increases with the...

We evaluate reforms to the U.S. tax system in a dynamic setup with heterogeneous married and single households, and with an operative extensive margin in labor supply. We restrict our model with observations on gender and skill premia, labor force participation of married females across skill...

The paper presents evidence of an upward ratchet in transfers and taxes in the U.S. around World-War II. This finding is explained within a political-economy framework involving an executive who sets defense spending and the median voter in the population who interacts with a (richer) agenda...

It is widely argued that Europe's unified monetary policy calls for international coordination at the fiscal level. We survey the issues involved with such coordination of fiscal policy as a demand management tool and we use a simple model to investigate the circumstances under which...

The paper explores the case for monetary and fiscal unification. Monetary policy suffers from an inflation bias because the monetary authorities are not able to commit. With international risk-sharing in a fiscal union, fiscal discipline suffers from moral hazard. An inflation target alleviates...
