The present paper aims to quantify efficiency properties of real world social security systems of various institutional designs in order to identify an optimal pension design. Starting from a benchmark economy without social security, we introduce alternative pension systems and compare the...

The present paper studies the efficiency properties of means-tested pay-as-you-go financed social security systems. Starting from a benchmark economy without social security, we introduce pension systems of various institutional designs and compare the costs arising from liquidity constraints as...

The present paper aims to quantify efficiency properties of flat and earnings-related pay-as-you-go financed social security systems of various institutional designs in order to identify an optimal pension design. Starting from a benchmark economy without social security, we introduce...

We construct a dynamic stochastic general equilibrium model with overlapping generations in order to analyze the optimality of means-testing pension benefits in the UK. While previous studies only consider the long-run welfare effects of alternative policy reforms, we compute the full transition...
