Assets in tax-deferred retirement accounts (TDA) and housing are two major components of household portfolios. In this paper, we develop a life-cycle model to examine the interaction between households' use of TDA and their housing decisions. The model generates life-cycle patterns of home...

In this paper we generalize the following result of Yaari (1965) on annuitization with an agent's optimal retirement: it is optimal for individuals to annuitize all of their wealth in the absence of bequest motive. We have other results that refine or extend the result of Yaari (1965). Full...

The global shift towards defined-contribution pension schemes has been accompanied by asymmetric risks and new responsibilities for households to plan and fund effectively their own retirement over the years. In this study, expressing and combining preferences for consumption, investment,...

In private pre-funded retirement savings systems, workers can be compelled by regulation to make minimum contributions to retirement accounts. We examine the impact of compulsory contributions into retirement savings (superannuation) accounts on individuals' lifetime consumption and wealth using...

In the aftermath of the financial crisis of 2008, there is increased concern about the potentially catastrophic pension default risk, which results in significant decreases in pension benefits. In order to address the challenge of annuity income uncertainty, I propose a dynamic annuitization...

We develop a retirement model with long-run income risk in which the wealth threshold for retirement is shown to be a function of the extent of the long-run income risk. By devising a new numerical algorithm, we solve the two-dimensional retirement problem. The two-dimensional retirement...

I study optimal consumption and investment for retirement in an economic environment where an individual has retirement flexibility and borrowing constraints. I show that Friedman's (1957) permanent income hypothesis (PIH) is generalized with retirement and constrained borrowing against future...

We explore how members of a collective pension scheme can share inflation risks in the absence of suitable financial market instruments. Using intergenerational risk sharing arrangements, risks can be allocated better across the various participants of a collective pension scheme than would be...

We analyze the impact of population aging on Japan’s household saving rate and on its public pension system and the impact of that system on Japan’s household saving rate and obtain the following results: first, the age structure of Japan’s population can explain the level of, and past and...

Feldstein [1985] posed the questions of what would be the optimal level of retirement benefit, and what would be the optimal mix between the pay-as-you-go system and the funded pension system under the assumption of an exogenous interest rate. We reconsider the problem with the addition of a...
