Many people do not understand the concepts of life expectancy and longevity risk, potentially leading them to under-save for retirement or to not purchase longevity insurance, which in turn could reduce wellbeing at older ages. We investigate alternative ways to increase the salience of both...

We propose a new framework for studying the evolution of heterogeneous beliefs in a dynamic feedback setting. Beliefs distributions are defined on a beliefs space representing a continuum of possible strategies agents can choose from. Agents base their choices on past performances, re-evaluating...

Quantal response equilibrium (QRE) of McKelvey and Palfrey (1995) relaxes the rationality requirement of Nash equilibrium by allowing for probabilistic mistakes or “noise in actions” while maintaining that beliefs are correct. QRE is well-studied, and much is known about the falsifiable...

This chapter provides a survey of the recent work on learning in the context of macroeconomics. Learning has several roles. First, it provides a boundedly rational model of how rational expectations can be achieved. Secondly, learning acts as a selection device in models with multiple REE...

I study the long-run behavior of an economy with two types of agents who differ in their beliefs and are endowed with homothetic recursive preferences of the Duffie-Epstein-Zin type. Contrary to models with separable preferences in which the wealth of agents with incorrect beliefs vanishes in...

In this paper, I survey the previous literature on the saving behavior of the aged in Japan and then present some survey data on the saving behavior of the aged in Japan that became available recently. To summarize the main findings of this paper, all previous studies as well as the newly...

How much retirement income is needed in order to maintain one's living standard at old age? As it is difficult to find a firm basis for an empirical treatment of this question, we employ a novel approach to assessing an adequate replacement rate vis- a-vis income in the pre-retirement period. We...
