Incentive effects of pension systems are usually estimated under the assumption that the institutional environment provides a single optimal 'pathway' for retirement. However, many countries provide competing pathways which may include several early retirement options in addition to normal...

In order to quantify these effects, we develop a computational general equilibrium model. We feed this multi-country overlapping generations model with detailed long-term demographic projections for seven world regions. Our simulations indicate that capital flows from fast-aging regions to the...
