Program

Pension systems are designed to meet three main objectives: to allow people to smooth consumption in their life cycle; to prevent poverty in old age; to establish a compact among generations. These goals, in their turn, are meant to insure individual risk, to overcome individual planning limitations and to provide some sharing for aggregate risks. Within the first category of risks, longevity and earnings risks are predominant; within the second, myopia and time inconsistency have to be addressed; within the third, demographic, economic and political risks should be as much diversified as possible.

Starting from this framework, the course aims at placing European pension systems and reforms in the context of the economic theory of households' savings, where imperfect and incomplete (financial and insurance) markets make room for the state to play an insurer's role, besides its traditional redistributive tasks. The logic behind the "insurance perspective" does not imply giving up the traditional objective of solidarity, both within and between generations; indeed, this aim is strengthened by highlighting the key role of risk diversification. Furthermore, thanks to an analytical framework based on insurance, measures aimed at achieving a given distributional goal are easily designed; while, if the insurance framework is ignored, redistribution in practice ends up with unforeseen and undesirable features.
Covered topics are:

i. Microeconomic foundations of retirement savings • Basic deterministic saving models: the LCH and the PIH (intertemporal optimization models: assumptions and main results) • Introducing uncertainty • Certainty Equivalence • Permanent Income Hypothesis
• Euler Equation • Precautionary savings • Life uncertainty and its effects. • The introduction of (actuarially fair) life insurance and the dominance of annuities • Why is the market for annuities everywhere so thin? • Why are reverse mortgages almost ignored?

ii. An economic analysis of social security (micro and macroeconomic features of social security) • Financing mode: PAYG vs. Funding • Pension formulae (DB vs. DC) • Actuarial fairness and neutrality • Measures of financial sustainability • Measures of adequacy • Redistribution (both within and between generations) • Incentive structure • (Induced) retirement • The aggregate pension wealth (debt) iii. Theoretical and empirical models of retirement • Stylised facts about retirement • Determinants of retirement choice • The implicit tax on postponing retirement (and related measures)
iv. The economics of pension reforms and the importance of Economic-Financial Literacy
• A political economic approach to social security • Assessing the political sustainability of social security reforms • EFL: concept, measurement, stylized facts, consequences of illiteracy

The Course is organized with Lectures, followed by discussions, and possibly a small written composition at the end of the course.
