Available in PDF, EPUB and Kindle. Book excerpt: This dissertation examines the effect of health and its associated variables on households' consumption and portfolio choices over life cycle. The first two essays constitute my job market paper, which explains why the risky portfolio share rises in wealth from two health mechanisms: endogenous health investment and medical expenditure risk. The third chapter explores the effect of health and health risk on households' optimal consumption and portfolio decisions over life cycle. Chapter 1 titled ``PORTFOLIO CHOICE AND HEALTH ACROSS WEALTH: EMPIRICAL EVIDENCE" illustrates the empirical relationship between the portfolio puzzle and the heterogeneity of health variables across wealth. Classic financial theory suggests that under the assumption of no borrowing constraints and no mean-reverting stock returns, households should hold a constant risky portfolio in spite of their wealth, ages and life horizons (Samuelson (1969) and Merton (1969, 1971)). Yet data from the Survey of Consumers Finances (SCF) show that the risky portfolio share of financial assets increases in wealth. In the literature, this is called the ``portfolio puzzle". Meanwhile, various sources of data indicate that, compared with the non-wealthy households, the wealthy people have better health, longer life horizon, higher out of pocket medical spending with lower uncertainty, and more health care time. All these facts suggest a novel correlation between the portfolio puzzle and the heterogeneity of health variables across wealth and provide a robust empirical foundation to explain the portfolio puzzle from a health perspective. In Chapter 2 titled ``A LIFE CYCLE MODEL OF PORTFOLIO CHOICE AND HEALTH", a life cycle model with endogenous health investment and medical expenditure risk is proposed to capture the key empirical features in the first chapter. This calibrated model remarkably matches the U.S. data. I find that endogenous health investment is essential to explain the portfolio puzzle: if health is exogenous without investment, the model can only could deliver 7.2% of the risky share gap across wealth. Medical expenditure risk is less important and has a larger effect on the non-wealthy group. If I abstract from medical expenditure risk, the risky shares increase for both groups: 24% for the low wealth group and 5% for the wealthy group. This life cycle model provides new insights into how health affects households' financial behavior. Chapter 3 titled ``OPTIMAL CONSUMPTION AND PORTFOLIO CHOICE WITH HEALTH RISK" investigates the effect of health and health risk on households' optimal consumption and portfolio allocations over the life cycle. The simulation results show that consumption, savings in bonds, and savings in stocks all increase with health. The risky portfolio share, which is the ratio of savings in stocks to the total financial assets, demonstrates the same tendency for both health states over the life cycle: at the very young age, the risky portfolio share is relatively high. Starting from the middle age, this share falls significantly and keeps steady until the end of life. For most of the lifetime, the risky portfolio share is positively related with health. These results emphasize the importance of health and its associated risk in consumption and portfolio decisions.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation considers household portfolio choice at the end of life-cycle. Three essays examine the importance of uncertainty about medical expenditure risk, cognitive aging, and subjective life horizon, and their role in explaining late-life savings decisions and portfolio allocation. Chapter 2 of the dissertation, entitled "Medical expenditure risk and precautionary saving: Evidence from Medicare Part D", tests the presence of precautionary saving motive to cope with medical expenditure risk. By examining Medicare Part D and it's association with household saving, I demonstrate that social insurance programs discourage private saving by reducing health-related uncertainty. Chapter 3 of the dissertation, entitled "Econometric analysis of cognitive abilities and portfolio choice", explores the role of cognitive aging in explaining a portfolio rebalancing towards safer assets at the end of life-cycle. In this essay, I argue that a gradual decrease in risky asset ownership at the end of life-cycle is in part driven by losing cognitive capabilities. I pay particular attention to testing whether such association is observed only on the extensive margin - that is, changes in ownership, or both risky asset ownership and reallocation across the intensive margin are affected. Causality is tested by exploiting exogenous variation in cognitive health, created by the introduction of Medicare Part D in 2006. Chapter 4 of the dissertation, entitled "Subjective life expectancy and portfolio choice: A household bargaining approach", examines collective decision-making when spouses have an incentive to bargain over portfolio allocation. This article starts with two well-known facts: (a) difference in life expectancy between husband and wife; and (b) age disparity in marriage. These two facts imply that females, on average, face 5 or 6 years longer retirement period to finance, and thus have more incentive to hold risky assets to achieve higher expected capital gains in the long-term. A difference in life expectancy then creates an incentive to bargain over how to allocate savings to risky and non-risky assets. The estimation results indeed show that more financial wealth is allocated to risky assets when a spouse with longer life expectancy has the "final say."

Download or read book Asset Market Participation and Portfolio Choice Over the Life Cycle written by Andreas Fagereng and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the life cycle of portfolio allocation following for 15 years a large random sample of Norwegian households using error-free data on all components of households' investments drawn from the Tax Registry. Both, participation in the stock market and the portfolio share in stocks, have important life cycle patterns. Participation is limited at all ages but follows a hump-shaped profile which peaks around retirement; the share invested in stocks among the participants is high and flat for the young but investors start reducing it as retirement comes into sight. Our data suggest a double adjustment as people age: a rebalancing of the portfolio away from stocks as they approach retirement, and stock market exit after retirement. Existing calibrated life cycle models can account for the first behavior but not the second. We show that incorporating in these models a reasonable per period participation cost can generate limited participation among the young but not enough exit from the stock market among the elderly. Adding also a small probability of a large loss when investing in stocks, produces a joint pattern of participation and of the risky asset share that is similar to the one observed in the data. A structural estimation of the relevant parameters of the model reveals that the parameter combination that fits the data best is one with a relatively large risk aversion, small participation cost and a yearly large loss probability of around 1.3 percent.
Download or read book Portfolio Choice Over the Life cycle in the Presence of trickle Down Labor Income written by Luca Benzoni and published by . This book was released on 2005 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Empirical evidence shows that changes in aggregate labor income and stock market returns exhibit only weak correlation at short horizons. As we document below, however, this correlation increases substantially at longer horizons, which provides at least suggestive evidence that stock returns and labor income are cointegrated. In this paper, we investigate the implications of such a cointegrated relation for life-cycle optimal portfolio and consumption decisions of an agent whose non-tradable labor income faces permanent and temporary idiosyncratic shocks. We find that, under economically plausible calibrations, the optimal portfolio choice for the young investor is to take a substantial ¿Xem short} position in the risky portfolio, in spite of the large risk premium associated with it. Intuitively, this occurs because the cointegration effect makes the present value of future labor income flows stock-like' for the young agent. However, for older agents who have shorter times-to-retirement, the cointegration effect does not have sufficient time to act, and the remaining human capital becomes more bond-like.' Together, these effects create a hump-shaped optimal portfolio decision for the agent over the life cycle, consistent with empirical observation
Download or read book Portfolio Allocation with Medical Expenditure Risk A Life Cycle Model and Machine Learning Analysis written by You Du and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper explores how the medical expenditure risk affects the households' portfolio choice across health status theoretically in a life cycle model and empirically using machine learning methods. Medical expenditure risk, as a background risk, can relocate households' financial decisions. A higher medical expenditure risk leads to a larger fluctuation and more uncertainty in households' consumption and therefore, utility. As a result, risk-free assets become more preferable. Our machine learning analysis shows evidence consistent with the theoretical life cycle model predictions. In particular, households with better health status tend to hold more stocks and conditional on being in good health status, households are willing to invest more in safe assets if they face a higher medical expenditure risk.

Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, quantitative models that have studied households' portfolio choices have focused exclusively on the different risk properties of alternative financial assets. We introduce differences in liquidity across assets in the standard life-cycle model of portfolio choice. More precisely, in our model, stocks are subject to transaction costs, as considered in recent macro literature. We show that, when these costs are calibrated to match the observed infrequency of households' trading, the model is able to generate patterns of portfolio stock allocation over age and wealth that are constant or moderately increasing, thus more in line with the existing empirical evidence.
Download or read book Simple Allocation Rules and Optimal Portfolio Choice Over the Lifecycle written by Victor Duarte and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We develop a machine-learning solution algorithm to solve for optimal portfolio choice in a detailed and quantitatively-accurate lifecycle model that includes many features of reality modelled only separately in previous work. We use the quantitative model to evaluate the consumption-equivalent welfare losses from using simple rules for portfolio allocation across stocks, bonds, and liquid accounts instead of the optimal portfolio choices. We find that the consumption-equivalent losses from using an age-dependent rule as embedded in current target-date/lifecycle funds (TDFs) are substantial, around 2 to 3 percent of consumption, despite the fact that TDF rules mimic average optimal behavior by age closely until shortly before retirement. Our model recommends higher average equity shares in the second half of life than the portfolio of the typical TDF, so that the typical TDF portfolio does not improve on investing an age-independent 2/3 share in equity. Finally, optimal equity shares have substantial heterogeneity, particularly by wealth level, state of the business cycle, and dividend-price ratio, implying substantial gains to further customization of advice or TDFs in these dimensions.
Download or read book Portfolio Choice in Retirement written by Motohiro Yogo and published by . This book was released on 2016 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a life-cycle model, a retiree faces stochastic health depreciation and chooses consumption, health expenditure, and the allocation of wealth between bonds, stocks, and housing. The model explains key facts about asset allocation and health expenditure across health status and age. The portfolio share in stocks is low overall and is positively related to health, especially for younger retirees. The portfolio share in housing is negatively related to health for younger retirees and falls significantly in age. Finally, out-of-pocket health expenditure as a share of income is negatively related to health and rises in age.
Download or read book Portfolio Choice and Health Status written by Harvey S. Rosen and published by . This book was released on 2003 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper analyzes the role that health status plays in household portfolio decisions using data from the Health and Retirement Study. The results indicate that health is a significant predictor of both the probability of owning different types of financial assets and the share of financial wealth held in each asset category. Households in poor health are less likely to hold risky financial assets, other things (including the level of total wealth) being the same. Poor health is associated with a smaller share of financial wealth held in risky assets and a larger share in safe assets. We find no evidence that the relationship between health status and portfolio allocation is driven by third variables' that simultaneously affect health and financial decisions. Further, the relationship between health status and portfolio choice does not appear to operate through the effect of poor health on individuals' attitudes toward risk, their planning horizons, or their health insurance status
Download or read book Portfolio Choice Over the Life Cycle when the Stock and Labor Markets are Cointegrated written by Luca Benzoni and published by . This book was released on 2011 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study portfolio choice when labor income and dividends are cointegrated. Economically plausible calibrations suggest young investors should take substantial short positions in the stock market. Because of cointegration the young agent's human capital electively becomes stock-like. However, for older agents with shorter times - to - retirement, cointegration does not have sufficient time to act, and thus their human capital becomes more bond-like. Together, these exects create hump - shaped life - cycle portfolio holdings, consistent with empirical observation. These results hold even when asset return predictability is accounted for.

Download or read book Life Cycle Portfolio Choice with Additive Habit Formation Preferences and Uninsurable Labor Income Risk written by Valery Polkovnichenko and published by . This book was released on 2005 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper explores the implications of the additive and endogenous habit formation preferences in the context of a life-cycle model of an investor who has stochastic uninsurable labor income. To solve the model, I analytically derive the habit - wealth feasibility constraints and show that they depend on the worst possible path of future labor income and on the habit strength, but not on the probability of the worst income. When there is only a slim chance of a severe income shock, the model implies much more conservative portfolios. The model also predicts that for some low to moderately wealthy households, the portfolio share allocated to stocks increases with wealth. Because of this feature, the model can generate more conservative portfolios for younger than for middle-aged households. One controversial finding is that for high values of the habit strength parameter, usually required for the resolution of asset pricing puzzles in general equilibrium, the life-cycle model predicts counterfactually high wealth accumulation.
