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 estimate the portfolio effect of changes in social security wealth exploiting a decade of Italian pension reforms as a source of exogenous variation. The Italian Survey of Household Income and Wealth records detailed portfolio data and elicits expectations of retirement outcomes, thus...

Intergenerational inequality and old-age poverty are salient issues in contemporary China. China's aging population threatens the fiscal sustainability of its pension system, a key vehicle for intergenerational redistribution. We analyze the positive and normative effects of alternative pension...

This paper explores the optimal risk sharing arrangement between generations in an overlapping generations model with endogenous growth. We allow for nonseparable preferences, paying particular attention to the risk aversion of the old as well as overall 'life-cycle' risk aversion. We provide a...

We estimate the effect of pension reforms on households’ expectations of retirement outcomes and private wealth accumulation decisions exploiting a decade of Italian pension reforms as a source of exogenous variation in expected pension wealth. Two parameters are crucial to estimate pension...

Private pension provision faces the challenging task of providing stable income streams during retirement. The challenge has increased markedly in the last decades due to volatile financial markets, falling interest rates and the withdrawal of employers and external insurers as risk bearers of...

We introduce tax contracts and examine how they affect government formation and welfare of voters in a democracy with proportional elections. A tax contract specifies a range of tax rates a party is committed to if in government. We develop a new model of party competition in which parties...

This paper investigates how a mandatory activation program in Denmark affects the job finding rate of unemployed workers. The activation program was introduced in an experimental setting where about half of the workers who became unemployed in the period from November 2005 to March 2006 were...

The aim of this paper is to better understand the impact of unemployment on the design of Pay-As-You-Go pension systems, in the context of population aging. We consider a model in which people differ according to age and face in every period a given probability of becoming unemployed. We first...

This paper analyses the changes to the tax and social security systems that have occurred since Czechoslovakia's `velvet revolution' in 1989. It shows how the tax system is moving to meet the requirements of a market economy. It suggests that a particularly high priority has to be given to...
