Public pensions in transition: an optimal policy path.

Area of Science:

• Economics
• Demography
• Public Finance

Background:

• Declining birth rates and fluctuating fertility present significant challenges for the financial sustainability of public pension systems.
• Aging populations worldwide necessitate innovative approaches to old-age insurance financing.

Purpose of the Study:

• To analyze the financial viability of old-age insurance under conditions of low fertility and population decline.
• To investigate the optimal balance between private savings and public pension schemes for long-term welfare.
• To determine optimal steady states and transition policies for public pension systems.

Main Methods:

• Development of a theoretical economic model.
• Analysis of a pay-as-you-go (PAYG) public pension system combined with private savings.
• Examination of both long-run economic effects and short-run implications.

Main Results:

• Determination of the economic properties of an optimal steady state for pension financing.
• Specification of an optimal transition path, representing the best feasible conversion policy.
• Identification of welfare-optimal combinations of private and public savings.

Conclusions:

• The study provides a framework for optimizing old-age insurance financing in the face of demographic shifts.
• Findings offer insights into designing sustainable public pension systems and effective conversion policies.
• The research highlights the importance of integrating private savings with public pension schemes for long-term financial security.
