Retirement Planning: Portfolio Choice for Long-Term Investors
(2008) Erlandzon, Karl
Retirement Planning: Portfolio Choice for Long-Term Investors Abstract This thesis consists of four papers. Common to the first three papers is the framework for analysis; a life-cycle model of a borrowing-constrained individual's consumption- and portfolio choices in the presence of uncertain labour income. The income process, taxes and pension systems are also realistically calibrated. The first paper investigates some welfare effects of forced saving through a mandatory pension scheme. Pension benefits stem from both a defined benefit and a notionally defined contribution part, the latter indexed to stochastic aggregate labour income. It is shown that, early in life, individuals attribute little value to their pension savings. Furthermore, for individuals in mid-life, the welfare loss associated with the dependency between pension returns and labour income growth is estimated to 1.2% of annual consumption. The second paper investigates the diversification demand of an individual faced with the alternative, through an individual account in a mandatory pension scheme, of exchanging aggregate labour income risk for equity exposure. It is shown that, depending on age and exchange premium, individuals will be either buyers or sellers of such swaps, and that inter-generational risk sharing can therefore be achieved. The third paper explores the recent transition from defined benefit to defined contribution for white-collar workers in Sweden. The main result is that individuals with the characteristic of a low expected pre-retirement income relative to average income during working life and high variance in earnings are winners (typically, men with university degree in the private sector), and that those with the opposite characteristic (typically, women with university degree in the public sector) would be losers. The aim of the fourth and final paper is to determine whether there is a home bias among the newly established Swedish National Pension Funds. Estimation errors in historical estimates of return moments make traditional analysis of the home bias puzzle work poorly. Therefore, this paper takes another approach by using the information available to the fund. The results demonstrate a significant bias towards domestic equities that cannot be explained by informational advantage or any other risk and return based explanation. Key words: Life-cycle, portfolio choice, pensions, Shiller-swap, defined contribution, defined benefit JEL: D31, D91, G11, G23, H24, J31 ISBN: 91-85169-33-1 (978-91-85169-33-7) Contact information: Karl Erlandzon, Department of Economics, School of Business, Economics and Law, University of Gothenburg, Box 640, SE-405 30 Göteborg; karl.erlandzon@lifeplan.se

The Bright Side of Shiller-Swaps: a solution to inter-generational risk sharing
(2006) Erlandzon, Karl; Carlsson, Evert; Department of Economics
This paper investigates the diversification demand of an agent, who is faced with the alternative to swap aggregate labour-income risk for equity-exposure, through her individual account in a mandatory-pension scheme. The framework for the analysis is a life-cycle model of a borrowing-constrained individual´s consumption- and portfolio-choice in the presence of uncertain labour-income and realistically calibrated tax- and pension systems. Pension benefits stem from both defined benefit and notionally defined contributions part, the latter being indexed to stochastic aggregate labour-income. We show that agents, depending on age and swap premium, agents will be either buyers or sellers of such a swap, and that inter-generational risk sharing can therefore be achieved.
The Dark Side of Wage Indexed Pensions
(2005) Erlandzon, Karl; Carlsson, Evert; Department of Economics
This paper investigates some welfare effects of forced saving through a mandatory pension scheme. The framework for the analysis is a life-cycle model of a borrowing constrained individual´s consumption and portfolio choice in the presence of uncertain labour income and realistically calibrated tax and pension systems. Pension benefits stem from both a defined benefit and a notionally defined contribution part, the latter being indexed to stochastic aggregate labour income. We show that agents attribute little value to their pension savings in early life. Furthermore, we estimate the welfare loss for individuals in mid-life associated with the dependency between pension returns and labour income growth to 1.2% in annual consumption.
