Evaluating the effects of population ageing on long-term growth and pension system sustainability in Bulgaria through an overlapping generations model

The article provides an overview of the simulations with a general equilibrium overlapping generations model, which is based on the theoretical setups, developed by Gertler and Grafenhofer et al. The model (BG-OLG) is calibrated for Bulgaria and evaluates the long-term effects of ageing on economic growth and public finance sustainability under different scenarios for the retirement age. On the basis of the model-based simulations, policy recommendations aimed at minimizing the macro-fiscal costs of population ageing are drawn.
