The first pillars of social security systems differ widely across European countries both in the contribution rate and intra-generational redistribution. What would the impact of these differences be if EU citizens had free access to all systems? This paper aims to highlight some basic features...

We explore the implications of monetary unification for real interest rates and (relative) public debt levels. The adoption of a common monetary policy renders the risk-return characteristics of the participating countries more similar, so that the substitutability of their public debt increases...

The aging of the populations in the OECD countries has prompted various calls for reforming the existing pay-as-you-go (PAYG) pension systems. Currently, there is renewed discussion in the United States about partial privatization where a fraction of the social security payroll tax would be...

The compromise enhancing effect of lobbying on public policy has been established in two typical settings. In the first, lobbies are assumed to act as 'principals' and the setters of the policy (the candidates in a Downsian electoral competition or the elected policy maker in a citizen-...

We show that, when school quality is measured by the educational standard and attaining the standard requires costly effort, secondary education needs not be a hierarchy with private schools offering better quality than public schools, as in Epple and Romano, 1998. An alternative configuration,...

We analyze optimal compensation schedules for the directors of two plants belonging to the same owner and producing the same good but serving geographically differentiated markets. Since the outcome of each director depends on his own effort and on a random variable representing market...

This paper studies the determinants of immigration policy in an economy with entrepreneurs and workers where a trade union has monopoly power over wages. The presence of the union leads a benevolent government to implement a high level of immigration and induces a welfare loss not only from an...

Many public goods are characterized by rivalry and/or excludability. This paper introduces both non-excludable and excludable public inputs into a simple endogenous growth model. We derive the equilibrium growth rate and design the optimal tax and user-cost structure. Our results emphasize the...

Paternalism, merit goods and specific egalitarianism are concepts we sometimes meet in the literature. The thing in common is that the policy maker does not fully respect the consumer sovereignty principle and designs policies according to some other criterion than individuals? preferences....

We develop a simple model of the exchange rate in which agents optimize their portfolio and use different forecasting rules. They check the profitability of these rules ex post and select the more profitable one. This model produces two kinds of equilibria, a fundamental and a bubble one. In a...
