At the end of 1982 South Korea had foreign debts of US $ 38 billion, the third highest total for a developing country after those of Mexico and Brazil. In contrast to these countries, however, South Korea has avoided debt crises so far. In view of the 20 or more rescheduling operations carried...

We suggest a political economy explanation for the stylized fact that intragenerationally more redistributive social security systems are smaller. Our key insight is that linking benefits to past earnings (less redistributiveness) reduces the efficiency cost of social security (due to endogenous...

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...

This paper analyzes the sustainability of intergenerational transfers in politico-economic equilibrium. Embedding electoral competition for the votes of old and young households in the standard Diamond (1965) OLG model, we find that intergenerational transfers naturally arise in a Markov perfect...

I argue that the offsetting effect of social security contributions on household retirement saving depends on how closely the social security programme imitates a private retirement saving plan (i.e. the ?actuarial? component of the social security programme) – the closer the design of the...

We develop a general equilibrium stochastic OLG model with heterogenous households. Households differ with respect to their productivity. Productivity depends stochastically on parents' unobservable investment in their child's human capital and an aggregate productivity shock. We introduce a...

This paper analyzes simultaneous voting on the wage tax rate and investment in public education with three overlapping generations and productivity differences inside each cohort. Wage tax revenue finances public education and social security benefits. The presence of productivity differences...

Using data from the first eleven waves of the German Socio-Economic Panel this study investigates the dynamic effects of health shocks on employment and economic wellbeing of older workers. A health shock trebles the probability of leaving the labor force and almost doubles the unemployment...

We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium...
