Zusammenfassung (übersetzt):
This study sought to quantify the impact of demographics on the expense of the public pensions as a share (%) of the Gross Domestic Product GDP, by 2060 and 2100, based upon a simplified forecasting model. The results show a strong expansion in expenditures due to the fast and intense process of population ageing, an increase which can be alleviated by raising the retirement age, increasing the level of employment and limiting the transmission of the active workers productivity gains to retirees and pensioners and other adjustment possibilities. In any case, the government should conduct reforms in order to correct distortions and minimize risks for the financial and actuarial sustainability of the Brazilian social insurance schemes.
