Adjustment mechanisms and intergenerational actuarial neutrality in pension reforms
In the context of the reform of defined benefit pension systems under population ageing, we focus on the introduction of automatic adjustment mechanisms linked to life expectancy. Our goal is to establish a relationship between changes in the key parameters of the pension system and changes in life expectancy, applying the principle of intergenerational actuarial neutrality. For a defined benefit pension scheme, we first obtain the fundamental adjustment equation and then, for particular cases, we derive different designs of automatic adjustment mechanisms depending on the involved parameter. We include a numerical application only for illustrative purposes.
Pensions, Economic Growth and Welfare in Advanced Economies
In this chapter, we analyse the effects of PAYG and funded pension systems on welfare. The debate on the choice between alternative systems focuses on their effects on savings, capital accumulation, labour supply, economic growth and inequality and the potential benefits of mixed systems in which a PAYG system with notional accounts is complemented by a funded pensions system. The main findings are as follows. Firstly, the redistribution of income among individuals makes the PAYG system an important part of any mixed system. Secondly, the design of the pension system should efficiently balance incentives and distortions with equality and insurance against individual idiosyncratic risks. Thi…
The Sustainability Factor: How Much Do Pension Expenditures Improve in Spain?
The reform of 2013 represented a qualitative leap in the reform of the Spanish pension system. Unlike its predecessors, it introduced two automatic resetting mechanisms similar to those of other European countries. The first is the sustainability factor, scheduled to come into effect in 2019 but delayed until 2023, and its ultimate reversal cannot be ruled out. The objective of this study was to quantify the savings, or the lowest expenditure, that can be achieved in the Spanish public contributory pension system by applying it. These savings are measured in terms of cash&mdash
