Dynamic portfolio choice with deferred annuities

We derive the optimal life-cycle portfolio choice and consumption pattern for households facing uncertain labor income, risky capital market, and mortality risk. In addition to stocks and bonds, the households have access to deferred annuities. Deferred payout life annuities are financial contracts providing life-long income to the annuitant after a specified period of time conditional on survival. We find that deferred annuities play an important role in household portfolios and generate significant welfare gains. Households with high benefits from state pensions, moderate risk aversion and moderate labor income risk purchase deferred annuities from age 40 and gradually increase their portfolio share. At retirement, deferred annuities account for 78% of total financial wealth. Households with low state pensions and high labor income risk purchase more annuities and earlier. Uncertainty with respect to future mortality rates has the same effect, i.e. household hedge against longevity risks using deferred annuities.     

Default, insurance, and debt over the life-cycle

The widespread use of debt and default suggests that unsecured credit markets play an important role in consumption smoothing. In this paper, I address two previously unanswered questions. First, how does policy towards debt default affect the evolution of consumption and net worth over the life-cycle? Second, how does debt default policy interact with social insurance over the life-cycle? The findings are as follows. First, US default policy appears “lax”, in the sense that it creates severe credit constraints, especially for the young. Second, eliminating default will lower consumption inequality among the young, but will increase it among the old. Third, social insurance alters default risk and, in turn, loan pricing, and therefore matters for purely intertemporal smoothing.     

The Determinants of Household Saving in China: A Dynamic Panel Analysis of Provincial Data

In this paper, we conduct a dynamic panel analysis of the determinants of the household saving rate in China using a life cycle model and panel data on Chinese provinces for the 1995–2004 period from China's household survey. We find that China's household saving rate has been high and rising and that the main determinants of variations over time and over space therein are the lagged saving rate, the income growth rate, (in many cases) the real interest rate, and (in some cases) the inflation rate. However, we find that the variables relating to the age structure of the population have the expected impact on the household saving rate in only one of the four samples. These results provide mixed support for the life cycle hypothesis as well as the permanent income hypothesis, are consistent with the existence of inertia or persistence, and imply that China's household saving rate will remain high for some time to come.     

Unsecured debt with public insurance: From bad to worse

In U.S. data, income interruptions, the receipt of public insurance, and the incidence of personal bankruptcy are all closely related. The central contribution of this paper is to evaluate bankruptcy protection and public insurance in a unified setting where each program alters incentives in the other. Our analysis delivers two striking conclusions. First, we find that U.S. personal bankruptcy law is an important barrier that prevents the public insurance system from improving welfare. Second, contrary to popular belief, we find that increases in the generosity of public insurance will lead to more, not less, bankruptcy.     

Asset allocation and location over the life cycle with investment-linked survival-contingent payouts

This paper shows how survival-contingent investment-linked payouts can enhance investor wellbeing in the context of a portfolio choice model which integrates uninsurable labor income and asymmetric mortality expectations. In exchange for illiquidity, these products provide the consumer with access to mutual-fund style portfolio choice, as well as the survival credit generated from pooling mortality risk. Our model generates optimal asset location patterns indicating how much to hold in liquid versus illiquid survival-contingent payouts over the lifetime, and also asset allocation paths, showing how to invest in stocks versus bonds. We show that the investor who moves her money out of liquid saving into survival-contingent assets gradually from middle age to retirement and beyond, will enhance her welfare by as much as 50%. The results are robust to the introduction of uninsurable consumption shocks in housing expenses, income flows during the worklife and retirement, sudden changes in health status, and medical expenses.     

Optimal life insurance purchase and consumption/investment under uncertain lifetime

In this paper, we consider optimal insurance and consumption rules for a wage earner whose lifetime is random. The wage earner is endowed with an initial wealth, and he also receives an income continuously, but this may be terminated by the wage earner’s premature death. We use dynamic programming to analyze this problem and derive the optimal insurance and consumption rules. Explicit solutions are found for the family of CRRA utilities, and the demand for life insurance is studied by examining our solutions and doing numerical experiments.     

Baby Boomer retirement security: The roles of planning, financial literacy, and housing wealth

We compare wealth holdings across two cohorts of the Health and Retirement Study: the early Baby Boomers in 2004, and individuals in the same age group in 1992. Levels and patterns of total net worth have changed relatively little over time, though Boomers rely more on housing equity than their predecessors. Most important, planners in both cohorts arrive close to retirement with much higher wealth levels and display higher financial literacy than non-planners. Instrumental variables estimates show that planning behavior can explain the differences in savings and why some people arrive close to retirement with very little or no wealth.     

Unsecured credit markets are not insurance markets

We study the extent to which unsecured credit markets have altered the transmission of increased income risk to consumption variability over the past several decades. We find that unsecured credit markets pass through increased income risk to consumption, irrespective of bankruptcy policy and the information possessed by lenders. If risk sharing has indeed improved over this period, the reasons do not therefore lie in the unsecured credit market.     

Mixing family with business: A study of Thai business groups and the families behind them

How does the structure of the families behind business groups affect the group's organization, governance, and performance? We construct a unique dataset of family trees and business groups for 93 of the largest business families in Thailand. We find a strong positive association between family size and family involvement in the ownership and control of the family businesses. The founders’ sons play a central role in both ownership and board membership, especially when the founder of the group is dead. Greater involvement by sons is also associated with lower firm-level performance, especially when the founder is dead. One hypothesis that emerges from our analysis is that part of the decay of family-run groups over time is due to the dilution of ownership and control across a set of equally powerful descendants of the founder, which creates a “race to the bottom” in tunneling resources out of the group firms.     

Heterogeneous life-cycle profiles, income risk and consumption inequality

Was the increase in income inequality in the US due to permanent shocks or merely to an increase in the variance of transitory shocks? The implications for consumption and welfare depend crucially on the answer to this question. We use Consumer Expenditure Survey (CEX) repeated cross-section data on consumption and income to decompose idiosyncratic changes in income into predictable life-cycle changes, transitory and permanent shocks and estimate the contribution of each to total inequality. Our model fits the joint evolution of consumption and income inequality well and delivers two main results. First, we find that permanent changes in income explain all of the increase in inequality in the 1980s and 1990s. Second, we reconcile this finding with the fact that consumption inequality did not increase much over this period. Our results support the view that many permanent changes in income are predictable for consumers, even if they look unpredictable to the econometrician, consistent with models of heterogeneous income profiles.     

Redistribution by insurance market regulation: Analyzing a ban on gender-based retirement annuities

We illustrate how equilibrium screening models can be used to evaluate the economic consequences of insurance market regulation. We calibrate and solve a model of the United Kingdom's compulsory annuity market and examine the impact of gender-based pricing restrictions. We find that the endogenous adjustment of annuity contract menus in response to such restrictions can undo up to half of the redistribution from men to women that would occur with exogenous Social Security-like annuity contracts. Our findings indicate the importance of endogenous contract responses and illustrate the feasibility of employing theoretical insurance market equilibrium models for quantitative policy analysis.     

Current consumption and future income growth: Synthetic panel evidence

Using group means computed from 20 years of high quality survey data, I show a strong and robust relation between households’ consumption growth and subsequent realizations of their income growth, including realizations as distant as six years later. The relation appears in multiple types of variation in income growth: in variation across cohort-education groups, in variation over the life cycle, and in variation over the business cycle. While other explanations are explored, the results are likely due to forward-looking households altering their current consumption in response to information they receive about their income years into the future, information that turns out to be accurate.     

The impact of consumer behavior on financial security of households in Poland

The paper applies the concept of identity to investigate whether consumer behavior matters for a household's financial security. It is assumed that considerable part of households may express their identity through status-oriented consumption. The research is carried out in two steps. First, the index of financial security is built and used to determine the level of financial security experienced by working-age families in Poland. Second, the simulation results based on an econometric model are employed to find the answer to the question: Does financial insecurity result more from the need to manifest consumption at the higher level than average in an income-group of which people are members, or people want to be distinguishable inside their own income-group but they do not identify with a group having consumption at visibly higher level, or from the need to improve self-image by bringing own consumption closer to the pattern of a group with higher wealth status of which they are not members? The source of data is the 2005-2009 Households Budget Surveys in Poland. The findings offer empirical evidence for the relevance of consumer behavior for financial security of households in Poland. Considerable part of households expresses identity through conspicuous consumption. Both groups of households, the insecurity rich and the insecurity poor, accept the same ranking of status goods: a car on the first position, next homes (housing and equipment) and clothes on the third place. Status-oriented consumption creates life beyond means and pushes even relatively rich households towards financial insecurity.     

Evaluating stock returns with time-varying risk aversion driven by trend deviations from the consumption-to-wealth ratio: An analysis conditional on income levels

Based on the cointegrating relationship between consumption and wealth, we estimate the long run consumption-to-wealth ratio for each of five consumer income quintiles as well as national data for benchmarking purposes. Short run deviations from the consumption-to-wealth ratio for each quintile are examined for their ability to forecast changes in future consumption, income, housing values, and especially stock returns. We demonstrate that these trend deviations when combined with consumption growth in a multifactor model, significantly improve the ability of the dividend-to-price ratio to forecast future market returns over short and intermediate horizons for consumers in the highest-income quintile. This paper contributes to the financial economic literature by showing that the highest-income consumers are forecasting future stock returns with the help of the persistence in the dividend-to-price ratio and are modifying their consumption accordingly.     

How Do People Cope with Natural Disasters? Evidence from the Great Hanshin-Awaji (Kobe) Earthquake in 1995

This paper investigates the coping strategies employed by victims of the Great Hanshin-Awaji (Kobe) earthquake in 1995. Using a unique household data set, we show that households that held a large amount of collateralizable assets before the catastrophe and were free from a binding borrowing constraint were able to maintain their consumption levels by borrowing. In contrast, households subject to a binding borrowing constraint before the disaster were unable to borrow to cope with the losses inflicted by the earthquake. On the other hand, both types of households relied on private transfers, depending on the extent of the damage.     

Interaction effects between dynamic hybrid products and traditional deferred annuities in the German life insurance market

Financial Markets and Portfolio Management - Dynamic hybrid products emerged in 2007 and are now well established in the German life insurance market. In this article, we study interaction effects...     

Volume,liquidity, and liquidity risk

Many classes of microstructure models, as well as intuition, suggest that it should be easier to trade when markets are more active. In the data, however, volume and liquidity seem unrelated over time. This paper offers an explanation for this fact based on a simple frictionless model in which liquidity reflects the average risk-bearing capacity of the economy and volume reflects the changing contribution of individuals to that average. Volume and liquidity are unrelated in the model, but volume is positively related to the variance of liquidity, or liquidity risk. Empirical evidence from the U.S. government bond and stock markets supports this new prediction.     

Efficient portfolios when housing needs change over the life cycle

We address the issue of the efficiency of household portfolios in the presence of housing risk. We treat housing stock as an asset and rents as a stochastic liability stream: over the life cycle, households can be short or long in their net-housing position. Efficient financial portfolios are the sum of a standard Markowitz portfolio and a housing risk hedge term that multiplies net housing wealth. Our empirical results show that net housing plays a key role in determining which household portfolios are inefficient. The largest proportion of inefficient portfolios obtains among those with positive net housing, who should invest more in stocks.
