what explains household stock holdings abstract this is an empirical study of the determinants of stock holdings using data from the us survey of consumer finances from 1992 to 2001 there is a great heterogeneity in the way households form their portfolios stock ownership is positively correlated with various measures of wealth age retirement savings and having sought financial advice it is negatively correlated with holdings of alternative risky investments such as investments in private businesses and with the willingness to undertake non financial investments in the future while we can predict reasonably well who holds stocks we have less predictive power about the share of stocks owned by those who hold positive amounts

time inconsistent preferences and the annuitization decision good news can involve difficult decisions for example winning a lottery jackpot can go along with the decision whether to have the jackpot paid out immediately as a lump sum or as periodic annual payments also when entering retirement most people face the decision whether they want their defined contribution account balance paid as a lump sum or to annuitize that amount the fact that people tend to choose the lump sum even if economic reasons suggest that they should choose the annuity is called the annuity paradox in a large online survey we find that people behave time inconsistent older people have a stronger tendency to choose the lump sum than younger people when they are asked to predict today what to choose when they retire this effect is considerably stronger for participants that answer simple time preference questions inconsistently our findings suggest to think about precommitment devices for the annuitization decision in the retirement case already at the time when the defined benefit plan is started

asset allocation and asset location household evidence from the survey of consumer finances abstract the rapid growth of assets in self directed tax deferred retirement accounts has generated a new set of financial decisions for many households in addition to deciding which assets to hold the traditional choice among bonds stocks and other investment classes households with substantial assets in both taxable and tax deferred accounts tda must now decide where to hold them this paper uses data from the survey of consumer finances to assess how many households have enough assets in both taxable and tax deferred accounts to face significant asset location choices it also investigates the asset location decisions these households make in 2001 49 of households had at least some assets in a tax deferred account and more than 11 million households had at least us 25 000 in both a taxable and a tax deferred account asset allocation inside and outside tax deferred accounts is quite similar with about 70 of assets in each location invested in equity securities roughly two thirds of households with financial assets in both taxable and tax deferred accounts hold portfolios that are tax efficient most of the other third could reduce their taxes by relocating heavily taxed fixed income assets to their tax deferred account for more than half of the households that hold apparently tax inefficient portfolios however a shift of less than us 10 000 in financial assets would eliminate tax inefficiency

individual risk in an investment based social security system this paper examines the risk aspects of an investment based defined contribution social security plan we focus on the risk after the plan is fully phased in individuals deposit a fraction of wages to a personal retirement account pra invest these funds in a 60 40 equity debt mix and in a similarly invested annuity at age 67 the value of the assets follows a random walk with mean and variance of a 60 40 equity debt portfolio over the period 1946 95 a mean log return of 5 5 percent net of administrative costs of 0 4 percent and a standard deviation of 12 5 percent we study he stochastic distributions of this process by doing 10 000 simulations of the 80 year experience of the cohort that reached age 21 in 1998 the resulting annuities are compared to the future defined benefits specified in current law the benchmark benefits with no uncertainty a 5 5 percent log return would permit the benchmark benefits to be purchased with pra deposits of 3 1 percent of payroll only one sixth of the pay as you go tax needed for the benchmark benefits saving a higher share of wages provides a cushion that protects the individual from the risk of an unacceptably low level of benefits for example pra deposits of 6 percent of wages reduces the probability that the benefits are less than the benchmark to 0 17 and the probability that they are less than 61 percent of the benchmark to 0 05 pra deposits of 9 percent of wages half of the tax rate required in a pay as you go system would substantially reduce these risks this pure investment based plan is an extreme case the investment risk can be reduced further by using a mixed system that combines pay as you go and investment based components or that makes intergenerational transfers conditional on the performance of stock and bond prices this abstract was borrowed from another version of this item

the determinants of household risky asset holdings australian evidence on background risk and other factors we study the portfolio allocation decisions of australian households using the relatively new household income and labour dynamics in australia hilda survey we focus on household allocations to risky financial assets our empirical analysis considers a range of hypothesised determinants of these allocations we find background risk factors posed by labor income uncertainty and health risk are important credit constraints and observed risk preferences play the expected role a positive age gradient is identified for risky asset holdings and home ownership is associated with greater risky asset holdings a unifying theme for many of our empirical findings is the important role played by financial awareness and knowledge in determining risky asset holdings many non stockholding households appear to lack the experience and financial literacy that might enable them to benefit from direct investment in stocks

cognitive constraints on valuing annuities this paper documents consumers difficulty valuing life annuities using a purpose built experiment in the american life panel we show that the prices at which people are willing to buy annuities are substantially below the prices at which they are willing to sell them we also find that buy values are negatively correlated with sell values and that the sell buy valuation spread is negatively correlated with cognition this spread is larger for those with less education weaker numerical abilities and lower levels of financial literacy our evidence contributes to the emerging literature on heterogeneity in financial decision making abilities particularly regarding retirement payouts jel d14 d91 g11 h55

the strategic bequest motive although recent research suggests that intergenerational transfers play an important role in aggregate capital accumulation our understanding of bequest motives remains incomplete we develop a simple model of strategic bequests in which a testator influences the decisions of his beneficiaries by holding wealth in bequeathable forms and by conditioning the division of bequests on the beneficiaries actions the model generates falsifiable empirical predictions that are inconsistent with other theories of intergenerational transfers we present econometric and other evidence that strongly suggests that bequests are often used as compensation for services rendered by beneficiaries

asset allocation and location over the life cycle with investment linked survival contingent payouts abstract 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 portfolio choice for long horizon investors with nontradable labor income this paper examines how risky labor income and retirement affect optimal portfolio choice with idiosyncratic labor income risk the optimal allocation to stocks is unambiguously larger for employed investors than for retired investors consistent with the typical recommendations of investment advisors increasing idiosyncratic labor income risk raises investors willingness to save and reduces their stock portfolio allocation towards the level of retired investors positive correlation between labor income and stock returns has a further negative effect and can actually reduce stockholdings below the level of retired investors financial advisors typically recommend that their customers invest more in stocks than in safe assets when they are working and to shift their investments towards safe assets when they retire jagannathan and kocherlakota 1996 malkiel 1996 by contrast the standard academic models of portfolio choice merton 1969 1971 samuelson 1969 show that retirement is irrelevant for portfolio decisions if investment opportunities are constant and human capital is tradable in this case the fraction of wealth optimally invested in risky assets should be constant over the lifetime of an individual recent research building on the pioneering work by merton 1971 shows that time varying investment opportunities result in portfolio rules with an intertemporal hedging component whose magnitude depends on the investment horizon of the investor kim and omberg 1996 balduzzi and lynch 1997 brennan schwartz and lagnado 1997 brandt 1999 campbell and viceira 1999 2001 barberis 2000 with time variation in investment opportunities retirement and death play an instrumental role as events that exogenously fix the individual s investment horizon more importantly retirement also marks the time at which individuals stop working and thereafter must live off their lifetime savings and possibly transfers from this perspective retirement matters for portfolio choice

cohort and target age effects on subjective survival probabilities implications for models of the retirement phase abstract subjective survival scaling factors are often estimated from one observation of life expectancy and treated as constant to any target age using new survey data on subjective survival probabilities we estimate a model incorporating cohort and target age varying beliefs in scaling factors both cohort age and target age matter respondents are pessimistic about overall life expectancy but optimistic about survival at advanced ages and older respondents are more optimistic than younger we propose a new theoretical model incorporating cohort and target age varying beliefs and illustrate their effects on the perceived value of annuities and on retirement phase consumption plans

portfolio choice and mortality contingent claims the general hara case abstract we solve a portfolio choice problem that includes mortality contingent claims and labor income under general hara preferences our contribution beyond existing literature is to i focus on the covariance between shocks to human capital and financial capital to ii model the utility of a family with basic needs and iii include life insurance and pension annuity claims in one unified life cycle model our solution employs a similarity reduction mapping which reduces the two dimensional hjb equation into one dimension this allows for the implementation of a quick numerical scheme and when shocks to human capital and financial capital are perfectly correlated a closed form expression is obtained as a special case

life cycle asset allocation with annuity markets abstract this paper derives the optimal consumption and portfolio choice pattern over the life cycle for households facing uninsurable labor income risk ruin risk stochastic capital markets and uncertain lifetime our model posits a dynamic utility maximizer with crra and epstein zin preferences who has access to liquid stocks bonds and illiquid life annuities we show that a considerable fraction of wealth is gradually annuitized until retirement and beyond to skim the mortality credit the remaining liquid wealth is mainly invested in stocks to compensate for riskless investment in life annuities the model allows us to assess the economic importance of common explanations for the empirically low annuity demand by analyzing participations rates annuitization fractions and welfare effects

annuities and individual welfare advancing annuity demand theory we present suffcient conditions for the optimality of full annuitization under market completeness that are substantially less restrictive than those used by yaari 1965 we examine demand with market incompleteness finding that positive annuitization remains optimal widely but complete annuitization does not how uninsured medical expenses affect demand for illiquid annuities depends critically on the timing of the risk a new set of calculations with optimal consumption trajectories very different from available annuity income streams still shows a preference for considerable annuitization suggesting that limited annuity purchases are plausibly due to psychological or behavioral biases

how elastic is the firm s demand for health insurance abstract we investigate the impact of tax subsidies on the firm s decision to offer insurance and on conditional firm spending on insurance we do so using the micro data underlying the employment cost index which has a major advantage for this exercise the matching of very high quality compensation data with information on a sample of workers in the firm we find that overall there is a moderately sized elasticity of insurance offering with respect to after tax prices 0 25 and a larger elasticity of insurance spending 0 7 we also find that the elasticities are driven primarily by small firms for whom the elasticity is larger and we find that there is significant value added to this employer based data replicating methods from standard micro data sources in our data lead to misleading estimates of these key parameters our simulation results suggest that major tax reform could lead to an enormous reduction in employer provided health insurance spending

the annuity puzzle remains a puzzle abstract we examine incomplete annuity menus background risk bequest motives and default risk as possible drivers of divergence from full annuitization contrary to what is often suggested in the literature we find that full annuitization remains optimal if saving is possible after retirement this holds irrespective of whether real or only nominal annuities are available whenever liquidity is desired individuals save sizeable amounts out of their annuity income to smooth consumption shocks similarly adding equity linked annuities to the menu does not increase welfare significantly since individuals can invest in stocks in order to get the desired equity exposure

labor supply flexibility and portfolio choice in a life cycle model abstract this paper examines the effect of the labor leisure choice on portfolio and consumption decisions over an individual s life cycle the model incorporates the fact that individuals may have considerable flexibility in varying their work effort including their choice of when to retire given this flexibility the individual simultaneously determines optimal levels of current consumption labor effort and an optimal financial investment strategy at each point in his life cycle we show that labor and investment choices are intimately related the ability to vary labor supply ex post induces the individual to assume greater risks in his investment portfolio ex ante

annuitization and asset allocation this paper examines the optimal annuitization investment and consumption strategies of a utility maximizing retiree facing a stochastic time of death under a variety of institutional restrictions we focus on the impact of aging on the optimal purchase of life annuities which form the basis of most defined benefit pension plans due to adverse selection acquiring a lifetime payout annuity is an irreversible transaction that creates an incentive to delay under the institutional all or nothing arrangement where annuitization must take place at one distinct point in time i e retirement we derive the optimal age at which to annuitize and develop a metric to capture the loss from annuitizing prematurely in contrast under an open market structure where individuals can annuitize any fraction of their wealth at anytime we locate a general optimal annuity purchasing policy in this case we find that an individual will initially annuitize a lump sum and then buy annuities to keep wealth to one side of a separating ray in wealth annuity space we believe our paper is the first to integrate life annuity products into the portfolio choice literature while taking into account realistic institutional restrictions which are unique to the market for mortality contingent claims

health status and portfolio choice causality or heterogeneity abstract this paper explores the role of unobserved individual characteristics in the health assets and health portfolio correlations we apply various econometrics models to a unique longitudinal dataset with rich information that allows for the exploitation of four different health indices our findings show strong cross sectional correlations between health and both financial and non financial assets but these correlations seem to be mainly driven by heterogeneity as the correlations largely disappear in the fixed effects model adverse health shocks however are found to motivate a safer portfolio choice even after individual fixed effects are controlled for a result consistent with the prediction made by the background risk theory our findings suggest that health shocks shift investment from risky assets toward other financial assets but keep the total financial assets unchanged

longevity risk retirement savings and financial innovation abstract over the last couple of decades unprecedented increases in life expectancy have raised important concerns for retirement savings we solve a life cycle model with longevity risk which can be hedged through endogenous saving and retirement decisions we investigate the benefits of financial assets designed to hedge the shocks to survival probabilities when longevity risk is calibrated to match forward looking projections those benefits are substantial this lends support to the idea that such hedging should be pursued by defined benefit pension plans on behalf of their beneficiaries finally we draw implications for optimal security design

new evidence on the money s worth of individual annuities this paper presents new information on the expected present discounted value of payouts on individual life annuities the annuity we examine is the single premium immediate life annuity an insurance product that pays out a nominal level sum as long as the covered person lives in exchange for an initial lump sum premium this annuity offers protection against the risk of someone outliving his saving given uncertainty about longevity for reasonable estimates of behavioral parameters we calculate that individual annuities are currently priced so that retirees without bequest motives should find these policies of substantial value in configuring their portfolios to smooth retirement consumption we also find that the expected present discounted value of payouts relative to the initial cost of the annuity has increased over the last decade these findings bear on the policy debate regarding the role of individual choice and self reliance in retirement planning this abstract was borrowed from another version of this item
