Abstract: The boom in the subprime mortgage market yielded many loans with high LTV ratios. From a large proprietary database on subprime mortgages, we find that choice of mortgage rate type is not linear in loan sizes. A fixed rate mortgage contract is a popular choice when loan size, measured by LTV ratio, is small. As LTV ratio increases, borrowers become more likely to choose adjustable rate mortgage contracts. However, when LTV reaches a certain level, borrowers start to switch back to fixed rate contracts. For these high LTV loans, fixed rate mortgages dominate borrowers' choices.

This project examines how employer-provided financial education for newly hired workers affects participation in retirement savings plans. The investigators partnered with six large employers to explore what financial education is currently offered to new hires. Each employer provided individual data on workers hired in 2008 and 2009. This report assesses the impact of information and delivery methods on participation and contribution rates. Several findings emerge. There is strong evidence that employees respond to match incentives.

Abstract: We propose a novel approach to estimate household income uncertainty at various future horizons and characterize how the estimated uncertainty evolves over the life cycle. We measure income uncertainty as the variance of linear forecast errors conditional on information available to households prior to observing the realized income. This approach is semiparametric because we impose essentially no restrictions on the statistical properties of the forecast errors.

Prior research has demonstrated that defaults have a powerful influence on economic outcomes in a wide range of settings because individuals often passively accept default options. This paper examines the degree to which defaults become less powerful as they become more extreme. We study a firm with a defined contribution retirement savings plan in which employees are automatically enrolled at a 12% contribution rate, a rate that is considerably higher than those studied in previous work.

Merchant fees and reward programs generate an implicit monetary transfer to credit card users from non-card (or “cash”) users because merchants generally do not set differential prices for card users to recoup the costs of fees and rewards. On average, each cash-using household pays $149 to card-using households and each card-using household receives $1,133 from cash users every year. Because credit card spending and rewards are positively correlated with household income, the payment instrument transfer also induces a regressive transfer from low-income to high-income households in general.

Abstract: Recent fiscal policies have aimed to stimulate household spending. In 2008, most households received one-time economic stimulus payments. In 2009, most working households received the Making Work Pay tax credit in the form of reduced withholding; other households, mainly retirees, received one-time payments. This paper quantifies the spending response to these different policies and examines whether the spending response differed according to whether the stimulus was delivered as a one-time payment or as a flow of payments in the form of reduced withholding.

The Community Development Department of the Federal Reserve Bank of San Francisco (FRBSF) commissioned this study to explore the feasibility of passing a financial education mandate in California. Specifically, we sought to understand the key barriers related to passing a mandate in California and to identify strategies to implement financial education in the current environment, despite the absence of a state mandate.

The exact cause of the massive defaults and foreclosures in the U.S. subprime mortgage market is still unclear. This paper investigates whether a particular aspect of borrowers' financial literacy—their numerical ability—may have played a role. We measure several aspects of financial literacy and cognitive ability in a survey of subprime mortgage borrowers who took out mortgages in 2006 or 2007 and match these measures to objective data on mortgage characteristics and repayment performance.

Abstract: This paper reviews the behavioral literature on inter-temporal choice and decision making under uncertainty and assesses the evidence on behavioral influences affecting consumers' credit decisions. The evidence reviewed suggests that consumers often do not consider all information available in the market nor deliberately evaluate each alternative. Consumers simplify, take shortcuts, and use heuristics, which may not always be optimal but nevertheless may be an economical means for achieving desired goals.

Abstract: This paper demonstrates the important role of job displacement in the household bankruptcy decision. I develop a dynamic, forward-looking model of unemployment and bankruptcy where persistent negative income shocks increase a household's likelihood of filing for bankruptcy both immediately and in the future. Consistent with the model's predictions, I find that households in the NLSY are 2.5 times more likely to file for bankruptcy in the year immediately following a job loss, at a rate of an additional 10 bankruptcies per 1000 job losses.
