Varying the Parameters of the Slovenian Pension System: an Analysis with an Overlapping-Generations General Equilibrium Model

This article presents an analysis of welfare effects in Slovenia, macroeconomic effects of the Slovenian pension reform and effects of the pension fund deficit on the sustainability of Slovenian public finances using a dynamic OLG general equilibrium model. Stress was laid upon varying two parameters of the current pension system: the age of retirement and the indexation rate of pensions. It was established that by tightening these parameters the elderly would lose, while the present and future generations would gain. The macroeconomic effects were in accordance with expectations; the employment level increased, while the effects of tightened parameters on real consumption were negative. Since the PAYG burden on incomes decreased, investment and thus the capital stock increased somewhat as well. Nevertheless, the long-term impact on real GDP appeared to be ambiguous. Without doubt the demographic slowdown of GDP growth has to be taken into account. Finally, tightening the parameters of the pension system substantially increased its long-term sustainability: while a lower indexation level of pensions considerably decreased the deficit of the public pension fund, increasing the retirement age was even able to delay the incidence of additional deficit.
