Abstract:
The Internet may significantly reduce search costs by enabling price comparisons on-line. This paper provides empirical evidence on how Internet comparison shopping sites affected the prices of life insurance in the 1990s. Using micro data on individual insurance policies and controlling for individual and policy characteristics, it shows that increases in Internet use significantly reduced the price of term life insurance. Further evidence shows that prices did not fall with rising Internet usage in the period before the sites began, nor for insurance types that were not covered on the sites. The results suggest that growth of the Internet has reduced term life prices by 8-15 percent. The results also show that the initial introduction of the Internet search sites is initially associated with an increase in price dispersion within demographic groups, but as use spreads, the dispersion falls.

Abstract:
The Internet has the potential to significantly reduce search costs by allowing consumers to engage in low-cost price comparisons online. This paper provides empirical evidence on the impact that the rise of Internet comparison shopping sites has had for the prices of life insurance in the 1990s. Using micro data on individual life insurance policies, the results indicate that, controlling for individual and policy characteristics, a 10 percent increase in the share of individuals in a group using the Internet reduces average insurance prices for the group by as much as 5 percent. Further evidence indicates that prices did not fall with rising Internet usage for insurance types that were not covered by the comparison websites, nor did they in the period before the insurance sites came online. The results suggest that growth of the Internet has reduced term life prices by 8 to 15 percent and increased consumer surplus by $115-215 million per year and perhaps more. The results also show that the initial introduction of the Internet search sites is initially associated with an increase in price dispersion within demographic groups, but as the share of people using the technology rises further, dispersion falls.

Abstract:
We test whether executive stock ownership affects firm payouts using the 2003 dividend tax cut to identify an exogenous change in the after-tax value of dividends. We find that executives with higher stock ownership were more likely to increase dividends after the tax cut in 2003, whereas no relation is found in previous periods when the dividend tax rate was higher. Relative to previous years, firms that initiated dividends in 2003 were more likely to reduce repurchases. The stock price reaction to the tax cut suggests that the substitution of dividends for repurchases may have been anticipated, consistent with agency conflicts.

Abstract:
Using the 2003 reduction in dividend tax rates to identify an exogenous change in the after-tax value of dividends to shareholders, we test whether stock holdings among company executives is an important determinant of payout policy. We have three primary findings. First, we find that when top executives have greater stock ownership, and thus an incentive to increase dividends for personal liquidity reasons, there is a significantly greater likelihood of a dividend increase following the 2003 dividend tax cut, whereas no such relation existed in the prior decade when the dividend tax rate was much higher. This finding is strongest for dividend initiations, and is robust to a rich set of firm and shareholder characteristics. Second, we provide evidence that approximately one-third of the firms that initiated dividends in 2003, a higher share than in previous years, scaled back share repurchases by an amount sufficient to reduce their total payouts. This offset potentially raised the total tax burden on shareholders at these firms because share repurchases are still tax-advantaged relative to dividends. Third, we find that while dividend-paying firms with a larger fraction of individual shareholders had greater stock price gains in response to the tax cut, the market appears to have at least partially anticipated that executives with high stock ownership might raise dividends at the expense of share repurchases and increase the average tax burden for individuals, which is consistent with the presence of agency conflicts within the firm.

Abstract:
This paper advances the theory of annuity demand. First, we derive sufficient conditions under which complete annuitization is optimal, showing that this well-known result holds true in a more general setting than in Yaari (1965). Specifically, when markets are complete, sufficient conditions need not impose exponential discounting, intertemporal separability or the expected utility axioms; nor need annuities be actuarially fair, nor longevity risk be the only source of consumption uncertainty. All that is required is that consumers have no bequest motive and that annuities pay a rate of return for survivors greater than those of otherwise matching conventional assets, net of administrative costs. Second, we show that full annuitization may not be optimal when markets are incomplete. Some annuitization is optimal as long as conventional asset markets are complete. The incompleteness of markets can lead to zero annuitization but the conditions on both annuity and bond markets are stringent. Third, we extend the simulation literature that calculates the utility gains from annuitization by considering consumers whose utility depends both on present consumption and a "standard-of-living" to which they have become accustomed. The value of annuitization hinges critically on the size of the initial standard-of-living relative to wealth.

Abstract:
Advancing annuity demand theory, we present sufficient 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.

Abstract:
This paper examines how the menu of investment options made available to workers in defined contribution plans influences portfolio choice. Using unique panel data of 401(k) plans in the U.S., we present three principle findings. First, we show that the share of investment options in a particular asset class (i.e., company stock, equities, fixed income, and balanced funds) has a significant effect on aggregate participant portfolio allocations across these asset classes. Second, we document that the vast majority of the new funds added to 401(k) plans are high-cost actively managed equity funds, as opposed to lower-cost equity index funds. Third, because the average share of assets invested in low-cost equity index funds declines with an increase in the number of options, average portfolio expenses increase and average portfolio performance is thus depressed. All of these findings are obtained from a panel data set, enabling us to control for heterogeneity in the investment preferences of workers across firms and across time.

Abstract:
This paper examines how the menu of investment options made available to workers influences portfolio choice. Using a unique panel data set of 401(k) plans, we examine four aspects of investment behavior. First, we show that the share of investment options in a particular asset class (i.e., company stock, equities, fixed income, and balanced funds) has a significant effect on participant portfolio allocations across these asset classes. For example, our estimates suggest that by increasing the share of equity funds from 1/3 to 1/2 (such as by adding an additional equity fund option to a plan that already offers company stock, one equity fund, and one fixed income fund), overall participant allocations to equity funds increase by nearly 6 percentage points. Second, we show that investment restrictions - such as requiring a match in company stock or placing a ceiling on the fraction of assets that can be held in a particular asset - can change the overall risk/return profile of the portfolio much more than would be expected in a standard portfolio model. For example, restricting investment in company stock is associated with an overall reduction in all equities, not just company stock. This finding is consistent with a view that participants view such restrictions as a form of implicit investment advice. Third, we find that investors respond to past asset returns, such as by allocating a higher fraction of contributions to equities when past 5-year returns on equities have been high. Finally, we provide strong evidence of inertia in investment behavior, as it takes several years for participant contributions to fully adjust to the addition of a new fund. Each of these findings has important implications for the design of any individual account based investment program, including one that would be part of Social Security.

Abstract:
This paper examines the role of the federal government in the market for terrorism reinsurance. We investigate the stock price response of affected industries to a sequence of thirteen events culminating in the enactment of the Terrorism Risk Insurance Act (TRIA) of 2002. In the industries most likely to be affected by TRIA - banking, construction, insurance, real estate investment trusts, transportation, and public utilities - the stock price effect was primarily negative. The Act was at best value-neutral for property-casualty insurers because it eliminated the option not to offer terrorism insurance. The negative response of the other industries may be attributable to the Act's impeding more efficient private market solutions, failing to address nuclear, chemical, and biological hazards, and reducing market expectations of federal assistance following future terrorist attacks.

Abstract:
Between 1990 and 2000, total sales of variable annuities in the U.S. grew from just over $5 billion to nearly $140 billion. These products now account for approximately half of all private market annuity sales. Variable annuities resemble mutual funds, but they qualify for special tax treatment as insurance products because they provide an option to convert to a life annuity. This paper describes the tax treatment of variable annuities and presents summary information on the ownership patterns for variable annuities. It also explores the relative importance of several distinct motives for household purchase of variable annuities. We use household data from the 1998 and 2001 waves of the Survey of Consumer Finances to examine ownership patterns and to test for the importance of tax and insurance considerations in variable annuity demand. We find that variable annuity ownership is highly concentrated among high income and high net wealth sub-groups of the population, although the concentration is lower than for several other categories of financial assets. We find mixed support for the role of tax considerations in generating variable annuity demand, and we outline a set of research issues that focus on household annuity purchases.

Abstract:
We show that the provision of even incomplete public insurance can substantially crowd out private insurance demand. We examine the interaction of the public Medicaid program with the private market for long-term care insurance and estimate that Medicaid can explain the lack of private insurance purchases for at least two-thirds and as much as 90 percent of the wealth distribution, even if comprehensive, actuarially fair private policies were available. Medicaid's large crowd out effect stems from the very large implicit tax (on the order of 60 to 75 percent for a median wealth individual) that Medicaid imposes on the benefits paid from private insurance policies. Importantly, Medicaid itself provides an inadequate mechanism for smoothing consumption for most individuals, so that its crowd out effect has important implications for overall risk exposure. An implication of our findings is that public policies designed to stimulate private insurance demand will be of limited efficacy as long as Medicaid continues to impose this large implicit tax.

Abstract:
This paper is the first to investigate the importance of geography in explaining equity market participation. We provide evidence to support two distinct local area effects. The first is a community ownership effect, that is, individuals are influenced by the investment behavior of members of their community. Specifically, a ten percentage-point increase in equity market participation of the members of one's community makes it two percentage points more likely that the individual will invest in stocks. We find further evidence that the influence of community members is strongest for less financially sophisticated households and strongest within 'peer groups' as defined by age and income categories. The second is that proximity to publicly-traded firms also increases equity market participation. In particular, the presence of publicly-traded firms within 50 miles and the share of U.S. market value headquartered within the community are significantly correlated with equity ownership of individuals. These results are quite robust, holding up in the presence of a wide range of individual and community controls, instrumental variables estimation, the inclusion of individual fixed effects, and specification checks to rule out that the relations are driven solely by ownership of the stock of one's employer.

Abstract:
This paper examines why some employers provide matching contributions to 401(k) plans in company stock and explores the implications of match policy for employee retirement wealth. Unlike stock option grants to non-executives, a firm's decision to match in company stock does not appear to be strongly correlated with cash flow or with measures of the benefits of aligning incentives of employees and employers. Rather, we find evidence that firms are more likely to provide the match in company stock if firm risk is low (i.e. lower stock price volatility and lower bankruptcy risk) and employees are also covered by a defined benefit plan. These findings suggest that firms consider the retirement security of their workers in making the match decision, either because firms want to minimize the risk of violating their fiduciary responsibility or because employees more fully value company stock at companies with lower firm-specific risk. Evidence also indicates that firms may want to match in company stock to boost employee ownership, perhaps to help deter takeovers, or because of the tax advantages for dividends on the company stock match. Simulation results suggest that sufficiently risk-tolerant individuals actually prefer a 401(k) plan at a company with a company stock match to a plan at a company with an unrestricted match, unless the equity premium is reduced substantially.

Abstract:
This paper examines the extent of redistribution that would occur under various annuity and bequest options as part of an individual accounts retirement program. I first estimate mortality differentials by gender, race, ethnicity and level of education using the National Longitudinal Mortality Study and document substantial differences. I then use these estimates to examine the expected transfers' that would take place between socioeconomic groups under different assumptions about the structure of an annuity program. Using an expected present discounted value or money's worth' calculation as the basis for comparison, I find that the size of transfers in an individual accounts program is highly sensitive to the benefit structure. For example, mandating a single-life, real annuity can result in expected transfers of as high as 20% of the account balance, often from economically disadvantaged groups toward groups that are better off. These transfers can be substantially reduced through the use of joint life annuities, survivor provisions and bequest options. For example, the largest expected negative transfer under a joint and full survivor annuity with a fully valued 20-year guarantee option is only 2% of the account balance. However, efforts to reduce the extent of redistribution generally do so at the cost of significantly lower annuity benefits paid to the individuals who contribute to the system.

Abstract:
This paper establishes a causal relation between an individual's decision of whether to own stocks and average stock market participation decision of the individual's community. We instrument for the average ownership of an individual's community with lagged average ownership of the states in which one's non-native neighbors were born. Combining this instrumental variables approach with controls for individual and community fixed effects, a broad set of time-varying individual and community controls, and state-by-year effects, rules out alternative explanations. To further establish that word-of-mouth communication drives this causal effect, we show that the results are stronger in more sociable communities.

Abstract:
As growing numbers of retirees reach retirement age with substantial balances in self-directed retirement plans, annuities are likely to become increasingly important instruments for drawing down retirement savings. This study explores recent trends in the pricing of single-premium annuity products in the United States. Virtually all of the annuity products currently available in the United States offer fixed nominal payouts, rather than an inflation-linked payout stream. After describing the money's worth' of the various types of nominal annuity products, this study considers the extent to which existing U.S. private annuity markets provide retirees with inflation-protected retirement income flows. Although there is effectively no market yet for inflation-indexed annuities in the United States, such products are available in other countries. The paper concludes by summarizing recent data on the pricing of both nominal and inflation-linked annuities in the United Kingdom and several other nations.

This paper explains four methods of "price indexing" initial Social Security retirement benefits, and discusses the effect of each method on the fiscal sustainability of Social Security, benefit levels and replacement rates, redistribution, and sensitivity of system finances to demographic and economic shocks. Of these methods, PIA Factor Indexing would generate the largest cost savings while reducing benefit growth at approximately an equal rate for all income levels. Methods that index the AIME, the formula "bend points", or both, would reduce benefit growth at a slower rate and would have different effects on benefit distribution and system sustainability.

Abstract:
This paper discusses the role of annuities in retirement planning. It begins by explaining the basic theory underlying the individual welfare gains available from annuitizing resources in retirement. It then contrasts these findings with the empirical findings that so few consumers behave in a manner that is consistent with them placing a high value on annuities. After reviewing the strengths and weaknesses of the large literature that seeks to reconcile these findings through richer extensions of the basic model, this paper turns to a somewhat more speculative discussion of potential behavioral stories that may be limiting demand. Overall, the paper argues that while further extensions to the rational consumer model of annuity demand are useful for helping to clarify under what conditions annuitization is welfare-enhancing, at least part of the answer to why consumers are so reluctant to annuitize will likely be found through a more rigorous study of the various psychological biases that individuals bring to the annuity decision.

Abstract:
This paper provides direct evidence of a causal link between the stock market participation of individuals and that of the other members of the community in which they reside. We first establish the presence of a robust positive correlation between the probability that an individual owns stock and the level of stock market participation of one's community, as measured by reporting dividend income on tax returns. We also show that conditional on owning stock, an individual is likely to own more (relative to income) when community ownership is higher. These results are robust to a wide range of individual and community controls, including measures of the importance of local firms (which have large independent effects), and specification checks to ensure that the relation is not driven solely by ownership of stock of one's employer. We then provide evidence that this community effect is at least partially driven by word of mouth by showing that the effect is stronger in more sociable communities. To demonstrate causality, we employ a novel instrumental variables strategy that uses the stock ownership rates of the non-local parents of one's local peers to instrument for community ownership. Further, we also control for heterogeneity in risk preferences by including individual-level fixed effects. We conclude that a ten percentage-point increase in equity market participation of the members of one's community makes it four to five percentage points more like the individual will invest in stocks. We also provide estimates of a direct parental effect, as well as suggestive evidence that one's home state may have lasting effects on one's stock market participation.

Abstract:
This paper explores the extent to which retirees can and do insure themselves against longevity risk in private pension plans. We first review the theoretical and empirical results on the value of annuities, and discuss reasons why households may choose not to further insure themselves against longevity risk. We then analyze current trends in the private pension market, and find that the shift from defined benefit plans to defined contribution plans is likely to reduce annuitization rates among future retirees. This is driven primarily by the fact that the majority of DC plans, such as 401(k) plans, do not even offer participants a life annuity option at retirement. Thus, individuals who wish to annuitize generally must do so in the individual market where payouts are lower due to a healthier mortality pool. Hence, we can forecast that in the coming decades, absent institutional and regulatory changes, overall annuitization rates may fall and households may be increasingly exposed to the risk of outliving their financial resources, while the currently small private individual annuity market may witness significant growth. Finally, we discuss several policy options designed to increase annuitization of retirement resources.

Abstract:
This paper uses the receipt of an inheritance to measure the effect of wealth shocks on retirement. Using the Health and Retirement Study (HRS), we first document that inheritance receipt is common among older workers - one in five households receives an inheritance over an eight-year period, with a median value of about $30,000. We find that inheritance receipt is associated with a significant increase in the probability of retirement. In particular, we find that receiving an inheritance increases the probability of retiring earlier than expected by 4.4 percentage points, or 12 percent relative to the baseline retirement rate, over an eight-year period. Importantly, this effect is stronger when the inheritance is unexpected and thus more likely to represent an exogenous shock to wealth.

Abstract:
Long-term care represents one of the largest uninsured financial risks facing the elderly in the United States. Whether the small size of this market is driven primarily by supply side market imperfections or by limitations to demand, however, is unresolved, largely due to the paucity of data about the structure of the private market. We provide what is to our knowledge the first empirical evidence on the pricing and benefit structure of long-term care insurance policies. We estimate that the typical policy purchased by a 65-year old has an average pricing load of about 18 percent and has a very limited benefit structure, covering only one-third of the expected present discounted value of long-term care expenditures. These findings are consistent with the presence of supply side market imperfections. However, we also find enormous gender differences in pricing -- typical loads are 44 cents on the dollar for men but better than actuarially fair for women -- that do not translate into differences in coverage. And, although purchased policies provide limited benefits, we demonstrate that more comprehensive policies are widely-available at similar loads, but are rarely purchased. These findings suggest that while supply-side market imperfections exist, they are not the primary cause of the small size of the private long-term care insurance market.

Abstract:
Building on the existing literature that examines the extent of redistribution in the Social Security system as a whole, this paper focuses more specifically on how Social Security affects the poor. This question is important because a Social Security program that reduces overall inequality by redistributing from high income individuals to middle income individuals may do nothing to help the poor; conversely, a program that redistributes to the poor may nonetheless be regressive according to broader measures if it also redistributes from middle to upper income households. We have four major findings. First, as we expand the definition of income to use more comprehensive measures of well-being, we find that Social Security becomes less progressive. Indeed, when we use an "endowment" defined by potential labor earnings at the household level, rather than actual earnings at the individual level, we find that Social Security has virtually no effect on overall inequality. Second, we find that this result is driven largely by the lack of redistribution across the middle and upper part of the income distribution, so it masks some small positive net transfers to those at the bottom of the lifetime income distribution. Third, in cases where redistribution does occur, we find it is not efficiently targeted: many high income households receive positive net transfers, while many low income households pay net taxes. Finally, the redistributive effects of Social Security change over time, and these changes depend on the income concept used to classify someone as "poor".

Abstract:
We explore four issues concerning annuitization options that retirees might use in the decumulation phase of an individual accounts' retirement saving system. First, we investigate the operation of both real and nominal annuity individual annuity markets in the United Kingdom. The widespread availability of real annuities in the U.K. dispels the argument that private insurance markets could not, or would not, provide real annuities to retirees. Second, we consider the current structure of two inflation-linked insurance products available in the United States, only one of which proves to be a real annuity. Third, we evaluate the potential of assets such as stocks, bonds, and bills, to provide retiree protection from inflation. Because equity real returns have been high over the last seven decades, a retiree who received income linked to equity returns would have fared very well on average. Nevertheless we cast doubt on the inflation insurance' aspect of equity, since this is mainly due to stocks' high average return, and not because stock returns move in tandem with inflation. Finally, we use a simulation model to assess potential retiree willingness to pay for real, nominal, and variable payout equity-linked annuities. For plausible degrees of risk aversion, inflation protection appears to have only modest value. People would be expected to value a variable payout equity-linked annuity more highly than a real annuity because the additional real returns associated with common stocks more than compensate for the volatility of prospective payouts. These finding are germane to concerns raised in connection with Social Security reform plans that include individual accounts.

Abstract:
This paper explores the value of purchasing joint life annuities for married couples. It describes the existing market for joint life annuities, and summarizes the range of annuity products that are currently available to couples. It then considers the value that married couples would place on access to an actuarially fair annuity market, and defines a measure of willingness-to-pay for annuities. This calculation differs from the analogous one for a single individual for two reasons. First, joint-and-survivor life tables differ from individual life tables. The life expectancy of the second-to-die in a married couple is substantially greater than that for a single individual. Second, joint life annuities provide time-varying payouts, because survivor benefit options permit the payout when both members of a couple are alive to differ from that when one member has died. The paper develops a new annuity valuation model and applies it to evaluate a married couple's utility gain from annuitization. The findings suggest that previous estimates of the utility gain from annuitization, which applied to individuals, overstate the benefits of annuitization for married couples. Since most potential annuity buyers are married, these findings may help to explain the limited size of the private market for single premium annuities.

Abstract:
This paper examines the economic rationale for, historical experience of, and current pressures facing the Pension Benefit Guaranty Corporation (PBGC). The PBGC is the government entity which partially insures participants in private - sector defined benefit pension plans against the loss of pension benefits in the event that the plan sponsor experiences financial distress and has an under - funded pension plan. The paper discusses three major flaws of the PBGC, namely, that the PBGC has: 1) failed to properly price insurance and thus encouraged excessive risk - taking by plan sponsors; 2) failed to promote adequate funding of pension obligations; and 3) failed to promote sufficient information disclosure to market participants. The paper then discusses potential ways to reform the PBGC so that it operates more in concert with basic economic principles.

Abstract:
In the aftermath of terrorist attacks of September 11, 2001, an important public policy question arose as to whether, and how, the federal government should intervene to provide a temporary backstop for property/casualty terrorism insurance. This paper examines several economic justifications for intervention and the rationale behind the Administration's proposal for a temporary and limited government program.

Abstract:
The terrorist attacks of September 11, 2001 represented a loss for commercial property & casualty insurers that was both unprecedented and unanticipated. After sustaining this record capital loss, the availability of adequate private insurance coverage against future terrorist attacks came into question. Concern over the potential adverse consequences of the lack of availability of insurance against terrorist incidents led to calls for federal intervention in insurance markets. This paper discusses the economic rationale for and against federal intervention in the market, and concludes that the benefits from establishing a temporary transition program, during which the private sector can build capacity and adapt to a dramatically changed environment for terrorism risk, may provide benefits to the economy that exceed the direct and indirect costs.

This paper examines household decisions about whether or not to annuitize retirement resources. A life-cycle model of consumption, implemented with the use of dynamic programming techniques, is used to construct a utility-based measure of annuity value for individuals and couples in the Health and Retirement Survey. Variation in the calculated 'annuity equivalent wealth' arises from differences in mortality risk, marital status, risk aversion, and the presence of pre-existing annuities such as Social Security. I find that a one-percentage point increase in the annuity equivalent wealth leads to nearly a one-percentage point increase in the ex ante probability of annuitizing balances in defined contribution pension plans. However, because much of the variation in the expected annuity decision is left unexplained by the life-cycle model, other factors are also analyzed. Health status and an individual's time horizon for financial decision making are significant determinants of the decision. There is no evidence that bequest motives are an important factor in making marginal annuity decisions.

Abstract:
Variable annuities have been one of the most rapidly growing financial products of the last two decades. Between 1996 and 2004, nominal sales of variable annuities in the U.S. more than doubled, from $51 billion to $130 billion. Variable annuities now account for approximately nearly two thirds of annuity sales. The investment returns associated with variable annuities resemble those from mutual funds, and variable annuity buyers can select among a range of asset allocation options. Variable annuities are considered insurance products under the tax law, so buyers are not taxed on their investment returns until they make withdrawals from their variable annuity accounts. This paper describes the tax treatment of variable annuities, presents summary information on their ownership patterns, and explores the importance of several distinct motives for household purchase of variable annuities. The discussion of tax treatment examines the impact of the 2001 and 2003 tax bills on the relative tax treatment of variable annuities and other financial products. Household data from the 1998 and 2001 Survey of Consumer Finances shows that variable annuity ownership is highly concentrated among high income and high net wealth sub-groups of the population. Variable annuity ownership is less concentrated, however, than ownership of several other types of financial assets. Evidence on the role of tax incentives in encouraging ownership of variable annuities is mixed. The probability of owning a variable annuity rises with the marginal tax rate throughout most of the income distribution, but it is lower for households in the top tax bracket than for those with slightly lower tax rates.

Abstract:
Rational models of risk-averse consumers have difficulty explaining limited annuity demand. We posit that consumers evaluate annuity products using a narrow investment frame that focuses on risk and return, rather than a consumption frame that considers the consequences for lifelong consumption. Under an investment frame, annuities are quite unattractive, exhibiting high risk without high returns. Survey evidence supports this hypothesis: whereas 72 percent of respondents prefer a life annuity over a savings account when the choice is framed in terms of consumption, only 21 percent of respondents prefer it when the choice is framed in terms of investment features.

Abstract:
This paper explores the current tax treatment of non-qualified immediate annuities and distributions from tax-qualified retirement plans in the United States. First, we describe how immediate annuities held outside retirement accounts are taxed. We conclude that the current income tax treatment of annuities does not substantially alter the incentive to purchase an annuity rather than a taxable bond. We nevertheless find differences across different individuals in the effective tax burden on annuity contracts. Second, we examine an alternative method of taxing annuities that would avoid changing the fraction of the annuity payment that is included in taxable income as the annuitant ages, but would still raise the same expected present discounted value of revenues as the current income tax rule. We find that a shift to a constant inclusion ratio increases the utility of annuitants, and that this increase is greater for more risk averse individuals. Third, we examine how payouts from qualified accounts are taxed, focusing on both annuity payouts and minimum distribution requirements that constrain the feasible time path of nonannuitized payouts. We describe briefly the origins and workings of the minimum distribution rules and we also provide evidence on the fraction of retirement assets potentially affected by these rules.

Abstract:
This paper provides evidence against the hypothesis that elderly individuals with strong bequest motives purchase term life insurance to offset mandatory annuitization by the existing Social Security system. Using new data on elderly households, this study is able to examine ownership of pure term life insurance separately from whole life, or cash-value, policies. This is an important distinction in the Annuity Offset Model' because the central implication is that term insurance is purchased in order to undo' excessive government annuitization in the form of Social Security, while whole life policies among the elderly primarily consist of tax deferred savings. Evidence is presented that many households simultaneously choose to hold privately purchased annuities and term life insurance, a choice that is inconsistent with the notion that these individuals are over-annuitized. Results also indicate that the hypothesized positive relationship between term insurance ownership and Social Security benefits does not hold once one analyzes term separately from cash value policies. Previous empirical results appear to have been overly favorable to the Annuity Offset Model due to the inability to adequately account for the strong correlation between whole life insurance ownership and Social Security benefits, a correlation that can be attributed to tax-deferred savings and attempts to protect human capital during one's younger working life. Because these findings suggest that households are not seeking to undo' Social Security for bequest reasons, these results have implications for the current debate over annuitization options in an individual accounts retirement system.

Abstract:
We examine individuals' self-reported willingness to exchange part of their Social Security inflation-indexed annuity benefit for an immediate lump-sum payment, using an experimental module in the 2004 Health and Retirement Study. Our first finding is that nearly three out of five respondents favor the lump-sum payment if it were approximately actuarially fair, a finding that casts doubt on several leading explanations for why more people do not annuitize. Second, there is some modest price sensitivity and evidence consistent with adverse selection; in particular, people in better health and having more optimistic longevity expectations are more likely to choose the annuity. Third, after controlling on education, more financially literate individuals prefer the annuity. Fourth, people anticipating future Social Security benefit reductions are more likely to choose the lump-sum, suggesting that political risk matters. Other factors such as sex, marital status, income, wealth, or the presence of children are not associated with respondents' relative preferences for the annuity versus the lump-sum.

Abstract:
This paper provides new evidence on what types of individuals are most likely to choose a defined contribution (DC) plan over a defined benefit (DB) plan. Making use of administrative data from the State Universities Retirement System (SURS) of Illinois, we study the decisions of nearly 50,000 new employees who make a one-time, irrevocable choice between a traditional DB plan, a portable DB plan, and an entirely self-managed DC plan. Because the SURS-covered earnings of these employees are not covered under the Social Security system, their choices provides insight into the DB vs. DC preferences of individuals with regard to a primary source of their retirement income. We find that a majority of participants fail to make an active decision and are thus defaulted into the traditional DB plan after 6 months. We also find that those individuals who are most likely to be financially sophisticated are most likely to choose the self-managed DC plan, despite the fact that, given plan parameters, the DC plan is inferior to the portable DB plan under reasonable assumptions about future financial market returns. We discuss both rational and behavioral reasons that might explain this finding.

Abstract:
This paper provides empirical evidence of Medicaid crowd out of demand for private long-term care insurance. Using data on the near- and young-elderly in the Health and Retirement Survey, our central estimate suggests that a $10,000 decrease in the level of assets an individual can keep while qualifying for Medicaid would increase private long-term care insurance coverage by 1.1 percentage points. These estimates imply that if every state in the country moved from their current Medicaid asset eligibility requirements to the most stringent Medicaid eligibility requirements allowed by federal law - a change that would decrease average household assets protected by Medicaid by about $25,000 - demand for private long-term care insurance would rise by 2.7 percentage points. While this represents a 30 percent increase in insurance coverage relative to the baseline ownership rate of 9.1 percent, it also indicates that the vast majority of households would still find it unattractive to purchase private insurance. We discuss reasons why, even with extremely stringent eligibility requirements, Medicaid may still exert a large crowd-out effect on demand for private insurance.

Abstract:
This paper provides new evidence on the decomposition of aggregate household wealth into life-cycle and transfer wealth. Using the 1998 Survey of Consumer Finances, it finds that transfer wealth accounts for approximately one-fifth to one-quarter of aggregate wealth, suggesting a larger role for life-cycle savings than some previous estimates. Despite the smaller aggregate size of transfer wealth, its concentration among a small number of households suggests that it can still have an important effect on the savings decisions of recipients. Estimates suggest that past receipts of transfer wealth reduce life-cycle savings by as much as dollar-for-dollar, while expected future transfers do not produce such a crowd-out effect.

Abstract:
This paper establishes a causal relation between an individual's decision of whether to own stocks and average stock market participation decision of the individual's community. We instrument for the average ownership of an individual's community with lagged average ownership of the states in which one's non-native neighbors were born. Combining this instrumental variables approach with controls for individual and community fixed effects, a broad set of time-varying individual and community controls, and state-by-year effects, rules out alternative explanations. To further establish that word-of-mouth communication drives this causal effect, we show that the results are stronger in more sociable communities.

Abstract:
This article explores the trade-offs associated with government issuance of longevity bonds as a way of stimulating private annuity supply in the presence of aggregate mortality risk. We provide new calculations suggesting a 5 percent chance that aggregate mortality risk could ex post raise annuity costs for private insurers by as much as 5-10 percentage points, with the most likely effect based on historical patterns toward the lower end of that range. While we suspect that aggregate mortality risk does exert some upward pressure on annuity prices, evidence from private market pricing suggests that, to the extent that private insurers are accurately pricing this risk, the effect is less than 5 percentage points. We discuss ways that the private market can spread this risk, while emphasizing that the government has the unique ability to spread aggregate risk across generations. We note factors that might hamper such an efficient allocation of risk, including potential political incentives for the government to shift more than the optimal amount of risk onto future generations, and the possibility that government fiscal policy might allocate risk less efficiently within each generation than would private markets. We also discuss how large-scale longevity bond issuance might affect government borrowing costs, as well as political economy aspects of how the proceeds from such a bond issuance might be used.

Abstract:
This article examines the distributional implications of mandatory longevity insurance when mortality heterogeneity exists in the population. Previous research has demonstrated the significant financial redistribution that occurs under alternative annuity programs in the presence of differential mortality across groups. This article embeds that analysis into a life-cycle framework that allows for an examination of distributional effects on a utility-adjusted basis. It finds that the degree of redistribution that occurs from the introduction of a mandatory annuity program is substantially lower on a utility adjusted basis than when evaluated on a purely financial basis. In a simple life-cycle model with no bequests, complete annuitization is welfare enhancing even for those with higher-than-average expected mortality rates, so long as administrative costs are sufficiently low. These findings have implications for policy toward annuitization, particularly as part of a reformed Social Security system.

Abstract:
Building on the existing literature that examines the extent of redistribution in the Social Security system as a whole, this paper focuses more specifically on how Social Security affects the poor. This question is important because a Social Security program that reduces overall inequality by redistributing from high income individuals to middle income individuals may do nothing to help the poor; conversely, a program that redistributes to the poor may nonetheless be regressive according to broader measures if it also redistributes from middle to upper income households.

We have four major findings. First, as we expand the definition of income to use more comprehensive measures of well-being, we find that Social Security becomes less progressive. Indeed, when we use an endowment defined by potential labor earnings at the household level, rather than actual earnings at the individual level, we find that Social Security has virtually no effect on overall inequality. Second, we find that this result is driven largely by the lack of redistribution across the middle and upper part of the income distribution, so it masks some small positive net transfers to those at the bottom of the lifetime income distribution. Third, in cases where redistribution does occur, we find it is not efficiently targeted: many high income households receive positive net transfers, while many low income households pay net taxes. Finally, the redistributive effects of Social Security change over time, and these changes depend on the income concept used to classify someone as poor.
