We study the long-run evolution of brand preferences, using new data on consumers' life histories and purchases of consumer packaged goods. Variation in where consumers have lived in the past allows us to isolate the causal effect of past experiences on current purchases, holding constant...

We formulate a test of the fungibility of money based on parallel shifts in the prices of different quality grades of a commodity. We embed the test in a discrete-choice model of product quality choice and estimate the model using panel microdata on gasoline purchases. We find that when gasoline...

We propose a new approach to studying the pass-through of credit expansion policies that focuses on frictions, such as asymmetric information, that arise in the interaction between banks and borrowers. We decompose the effect of changes in banks' cost of funds on aggregate borrowing into the...

Agents with more experience make better choices. We measure learning dynamics using a panel with four million monthly credit card statements. We study add-on fees, specifically cash advance, late payment, and overlimit fees. New credit card accounts generate fee payments of $15 per month....

Strong bequest motives can explain low retirement spending, but so equally can strong precautionary motives. Given this identification problem, the recent tradition has been largely to ignore bequest motives. We develop a rich model of spending in retirement that allows for both motives, and...

Previous research has used survey and diary data to carefully document that Food Stamp recipients decrease their expenditures and consumption of food throughout the benefit month, the beginning of which is defined by the date on which benefits are distributed. The reliance on survey and diary...

We use responses to a survey and experiment with participants in Mexico's privatized social security system to examine how financial literacy impacts workers' choice behavior and how simplifying information on management fees may increase measures of price elasticity sensitivity among the...

We use detailed data from a large retail panel to study the effect of participation in the Supplemental Nutrition Assistance Program (SNAP) on the composition and nutrient content of foods purchased for at-home consumption. We find that the effect of SNAP participation is small relative to the...

We estimate the effect of information and expertise on consumers' willingness to pay for national brands in physically homogeneous product categories. In a detailed case study of headache remedies we find that more informed or expert consumers are less likely to pay extra to buy national brands,...

We explore the effects of mandatory third-party review of mortgage contracts on consumer choice--including the terms and demand for mortgage credit. Our study is based on a legislative pilot carried out by the State of Illinois in a selected set of zip codes in 2006. Mortgage applicants with low...
