Is there an economic rationale for pronatalist policies? In this paper we propose and analyze a particular market failure that may lead to inefficiently low equilibrium fertility and therefore to a need for government intervention. The friction we investigate is related to the ownership of...

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...

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 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...

Recent empirical studies criticize the sluggish financial integration in the euro area and find that only interbank money markets are fully integrated so far. This paper studies the optimal regional and/or sectoral integration of financial systems given that integration is restricted to the...

This paper studies the implications of cross-border financial integration for financial stability when banks' loan portfolios adjust endogenously. Banks can be subject to sectoral and aggregate domestic shocks. After integration they can share these risks in a complete interbank market. When...

We analyse the impact of micro-founded political institutions on environmental policy and economic growth. We model an overlapping-generations economy, where individuals differ in preferences over the environment (as well as in age). Labour taxation and capital taxation is used to finance a...

In many countries pension systems involve some form of earnings test; i.e., an individual’s benefits are reduced if he has labour income. This paper examines whether or not such earning tests emerge when pension system and income tax are optimally designed. We use a simple model with...

This paper studies the determination through majority voting of a pension scheme when society consists of far-sighted and myopic individuals. All individuals have the same basic preferences but myopics tend to adopt a short term view (instant gratification) when dealing with retirement saving....

In this Paper, we study the role of subsidies to fertility in ensuring the political viability of unfunded social security (SS). In our model, agents are heterogeneous in age and income. Young generations confront promises made previously by older generations, and in turn choose current levels...
