Why do firms offer risky defined benefit pension plans?
Even risky pension sponsors could offer essentially riskless pension promises by contributing a sufficient level of resources to their pension trust funds and by investing those resources in fixed-income securities designed to deliver their payoffs just as pension obligations are coming due. However, almost no firm has chosen to fund its plan in this manner. We study the optimal funding choice for plan sponsors by developing a simple model of pension financing in which the total compensation offered to workers must clear the labor market. We find that if workers understand the implications of ...

The geography of stock market participation: the influence of communities and local firms
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 other members of one's community makes it two percentage points more likely that the individual will invest in stocks, conditional on a rich set of controls. We find further evidence that the influence of ...

A new look at the wealth adequacy of older U.S. households
We construct two measures of the current wealth adequacy of older U.S. households using the 1998--2006 waves of the Health and Retirement Study (HRS). The first is the ratio of "comprehensive wealth"--defined as net worth plus the expected value of future income streams--to the wealth that would be needed to generate expected poverty-line income in future years. By this measure, we find that the median older U.S. household is reasonably well situated, with a "poverty ratio" of about 3.9 in 2006. However, we find that about 18 percent of households have less wealth than would be needed to ...

Measuring Aggregate Housing Wealth : New Insights from an Automated Valuation Model
We construct a new measure of aggregate U.S. housing wealth based on Zillow's Automated Valuation Model (AVM). AVMs offer advantages over other methods because they are based on recent market transaction prices, utilize large datasets which include property characteristics and local geographic variables, and are updated frequently with little lag. However, using Zillow's AVM to measure aggregate housing wealth requires overcoming several challenges related to the representativeness of the Zillow sample. We propose methods that address these challenges and generate a new estimate of aggregate ...

The current state of U.S. household balance sheets
The Board of Governors of the Federal Reserve System is responsible for two of the most widely used datasets containing information about U.S. household balance sheets: the quarterly macro-level Financial Accounts of the United States (FA, formerly known as the Flow of Funds Accounts) and the triennial microlevel Survey of Consumer Finances (SCF). The FA is very timely, but the data can be used only to describe the household sector as a whole. The SCF provides the micro-level detail needed to capture heterogeneity in household finances, but the data are available only with a long lag. The ...

New evidence on 401(k) borrowing and household balance sheets
Despite news reports suggesting a rise in 401(k) borrowing in recent years, we find that the share of eligible households with 401(k) loans in the 2007 Survey of Consumer Finances was about 15 percent, roughly what it has been since 1995. We find that the best predictors of 401(k) borrowing appear to be the presence of liquidity or borrowing constraints and the size of 401(k) balances relative to income. Since the ongoing financial crisis has likely caused these factors to move in opposite directions, the predicted effect of the crisis on 401(k) borrowing is ambiguous. More fundamentally, we ...

Does health affect portfolio choice?
Previous studies find a strong and positive empirical connection between health status and the share of risky assets held in household portfolios. But is this relationship truly causal, in the sense that households respond to changes in health by altering their portfolio allocation, or does it simply reflect unobserved differences across households? We find that most of the variation by health is on the extensive margin of stock ownership (rather than the marginal allocation conditional on ownership), which more plausibly points to non-causal explanations. Moreover, we find that any link ...

Borrowing from yourself: 401(k) loans and household balance sheets
We examine 401(k) borrowing since 1992 and identify a puzzle: despite potential gains from borrowing against 401(k) assets instead of from other sources, most eligible households eschew 401(k) loans, including many who carry relatively expensive balances on credit cards and auto loans. We estimate that households with access to 401(k) loans could have saved about $3.3 billion in 2004--about $200 per household--by shifting debt to 401(k) loans. We find that liquidity constrained households are most likely to borrow against their accounts; however, the fastest growth has been among higher ...

Should risky firms offer risk-free DB pensions?
We develop a simple model of pension financing to study the effects of pension risk on shareholder value. In the model, firms minimize costs, total compensation must clear the labor market, and a government pension insurer guarantees a portion of promised benefits. We find that in the absence of mispriced pension insurance, the optimal pension strategy under most specifications is to immunize all sources of market risk. Mispriced pension insurance, however, gives firms the incentive to introduce risk into their pension promises, offering an explanation for some of the observed prevalence of ...

Do households have enough wealth for retirement?
Dramatic structural changes in the U.S. pension system, along with the impending wave of retiring baby boomers, have given rise to a broad policy discussion of the adequacy of household retirement wealth. We construct a uniquely comprehensive measure of wealth for households aged 51 and older in 2004 that includes expected wealth from Social Security, defined benefit pensions, life insurance, annuities, welfare payments, and future labor earnings. Abstracting from the uncertainty surrounding asset returns, length of life and medical expenses, we assess the adequacy of wealth using two ...
