Definition
An unfunded pension system, also known as a pay-as-you-go (PAYG) pension system, is a retirement scheme where current workers’ contributions are used to pay the pensions of current retirees. Unlike funded pension systems, there are no accumulated reserves to cover future pension liabilities.
Historical Context
The pay-as-you-go system dates back to ancient times but was formally introduced in modern economies during the 20th century. One of the most well-known implementations is the United States Social Security system, which was established in 1935 during the Great Depression to provide financial security to elderly citizens.
Types/Categories
- Public PAYG Systems: Managed by the government and usually mandatory for all working citizens.
- Private PAYG Systems: Administered by private sector entities; less common and typically used in conjunction with public systems.
- Hybrid Systems: Combine elements of both PAYG and funded pension systems.
Key Events
- 1935: Introduction of the Social Security Act in the United States.
- 1950s-1960s: Expansion of PAYG pension systems across Europe.
- 1990s: Reforms in several countries due to demographic shifts and financial sustainability concerns.
Detailed Explanation
In a PAYG system, there are no pre-saved funds set aside. Instead, the contributions collected from current employees are immediately used to pay the pensions of current retirees. The effectiveness of such a system relies on a stable or growing population and workforce.
Mathematical Formulas/Models
The sustainability of a PAYG system can be analyzed using a basic demographic and economic model:
Where:
- \( P \) = Pension benefits
- \( C \) = Contribution rate
- \( w \) = Average wage
- \( n \) = Number of workers
- \( r \) = Number of retirees

Importance and Applicability
PAYG systems are essential for providing a safety net for retirees, especially in countries with limited access to other retirement savings options. They are particularly important in stabilizing the financial well-being of older populations.
Examples
- Social Security (USA): One of the largest PAYG systems globally.
- National Insurance (UK): A PAYG scheme that contributes to the state pension.
Considerations
- Demographic Changes: Declining birth rates and increasing life expectancy can strain the system.
- Economic Growth: Slower economic growth can reduce the inflow of contributions.
- Policy Adjustments: Regular policy reviews are necessary to maintain financial sustainability.
Related Terms with Definitions
- Funded Pension System: A system where contributions are invested to generate returns for future pension payments.
- Social Security: Government programs that provide economic assistance to people with an inadequate or no income.
Comparisons
- PAYG vs. Funded Systems: Funded systems accumulate assets over time, providing greater security against demographic changes, whereas PAYG systems rely on current workers’ contributions.
- Public vs. Private PAYG Systems: Public systems are state-managed, usually mandatory, while private systems offer more flexibility but less universality.
Interesting Facts
- The earliest forms of PAYG systems can be traced to Bismarck’s Germany in the late 19th century.
- PAYG systems can adapt more quickly to economic changes compared to funded systems.
