Using the Panel Study of Income Dynamics, we document that controlling for observable characteristics, household investors' likelihood of entering the stock market within the ensuing five years is about 20% to 30% higher if their parents or children had entered the stock market during the previous five years. By eliminating competing hypotheses such as preference similarity and herding, we argue that these findings highlight the significance of information sharing regarding household financial decisions.

The maturity date of a mortgage loan marks the end of monthly mortgage payments for homeowners. In the period after the last payment, homeowners experience an increase in their disposable income. Our study interprets this event as an anticipated increase in income, and tests whether households smooth consumption over the transition period as predicted by the rational-expectation life-cycle–permanent-income hypothesis. We find households do not alter nondurable-goods consumption in the period following the last mortgage payment. Instead, they increase both financial savings and savings in durable goods such as house furnishings and entertainment equipment in the year of the last mortgage payment.

Theoretical models have long recognized the role of investor disagreements in the marketplace, but little evidence is documented regarding how belief dispersion affects trading activities in the broad equity market. Using over three decades of data from a survey of US households, we introduced a novel measure of household macroeconomic belief dispersion and document its positive relationship with market-wide stock trading volume, even after controlling for an array of professional analysts’ belief dispersion. Results are more pronounced for the belief dispersion among households who are more likely to own stocks. Furthermore, we show that the household belief dispersion is priced in the cross-section of stock returns, whereas that among professional analysts is not.

This paper explores the dynamics of unsecured credit supply over the recent credit cycle and around the passage of the CARD Act. We examine a unique data set of over 200,000 credit card mail solicitations to a representative sample of households and introduce credit card offers as a direct, informative measure of supply of such credit. Contrasting personal credit card offer dynamics before and after the passage of the CARD Act with those of personal loans, auto loans, and corporate credit cards, we find that lenders reduced credit supply of personal credit cards to nonprime borrowers in response to the CARD Act. Our analysis highlights the importance of separately examining supply and demand responses to assess the unintended consequences of regulation.

The CARD Act restricts consumer credit card issuers’ ability to raise interest rates. We examine whether the Act influences the degree to which an issuer adjusts offered interest rates in response to changes in interest rates offered by other lenders in credit card solicitations—the price responsiveness. Using small business card offers as a control group, we find a significant decline in the price responsiveness after the Act. The decline is concentrated among other lenders’ rate reductions rather than rate increases and is more pronounced in areas with more subprime borrowers. The results underscore an unintended consequence of regulating the consumer credit market.

A large literature shows that the self-employed underreport their income to tax authorities. In this paper, we quantify the extent to which the self-employed also systematically underreport their income in U.S. household surveys. We use the Engel curve describing the relationship between income and expenditures of wage and salary workers to infer the actual income, and thus the reporting gap, of the self-employed based on their reported expenditures. On average, the self-employed underreport their income by about 25%. We show that failing to account for such income underreporting leads to biased conclusions in a variety of settings.

Comprehensive data on consumption expenditures have historically not been collected in US longitudinal household surveys. The Panel Study of Income Dynamics (PSID) expanded its expenditure data collection in 1999 and 2005. We examine these new expenditure data, highlighting several unique features of the PSID data. We then compare the PSID expenditure data with those in the Consumer Expenditure Survey (CE). We document that the PSID data cover nearly the entire scope of the CE data, and the mean statistics of total expenditures compare favorably between the two surveys. However, significant differences remain for certain expenditure categories.

Using data recently collected by the Panel Study of Income Dynamics, we find that the intergenerational correlation in expenditures is no larger than that in income, suggesting limited intra-family risk-sharing. On the other hand, even after controlling for the intergenerational correlation in income, the expenditures correlation remains significant. This suggests that other factors such as preferences, access to credit, and non-pecuniary inter vivos transfers potentially played a role in consumption smoothing across generations within a family. We also find that the correlation coefficients estimated using food and imputed total expenditures are smaller than that estimated using the measured total expenditures.
