Working Paper n°2018-13 – What’s gone wrong in the design of PAYG systems? – Riccardo Magnani (CEPN)

In order to face the population ageing problem, most countries with PAYG systems introduced pension reforms during the last twenty years. However, in many cases these reforms are considered as insufficient to guarantee the pension sustainability; in other cases, the pension sustainability is achieved through the introduction of drastic reforms and, thus, at the expense of a dramatic reduction in the well-being of current and future generations.

This analysis has been criticized for two main complementary reasons: firstly, it does not duly consider the aggregate pro-cyclicallity of profits; secondly, due to an overly aggregate analysis, some inferences about the relation between aggregate leverage and systemic fragility are potentially misleading. In this paper, we take these criticisms into account by building an …[Lire la suite]
