Economic theory predicts that earnings uncertainty increases precautionary saving and causes households to include relatively liquid assets in their portfolios. Risk avoidance and the demand for liquidity cause these portfolio choices. Studies investigating United States evidence of...

Significant departures from log normality are observed in income data, in violation of Gibrat's law. We identify a new empirical regularity, which is that the distribution of consumption expenditures across households is, within cohorts, closer to log normal than the distribution of income. We...

Do individuals use all information at their disposal when forming expectations about future events? In this paper we present an econometric framework to answer this question. We show how individual information sets can be characterized by simple nonparametric exclusion restrictions and provide a...

While it is common to use income uncertainty to explain household saving decisions, there is much disagreement about the importance of precautionary saving. This paper suggests that income uncertainty is not an important motive for saving, although households do have other precautionary reasons...

Do households use savings to buffer against income fluctuations? Despite its common use to understand household savings decisions, the evidence for the buffer-stock model is surprisingly weak and inconsistent. This paper develops new testable implications based on a property of the model that...

What financial services matter for growth? This paper examines the effects national banks had on growth in the United States from 1870-1900. These banks were commercial not investment banks: they made short term loans and could not take land as collateral. I use the discontinuity in entry caused...

Although many view financial access as a means of reducing poverty or increasing growth, empirical studies have produced contradictory results. One problem is that most studies cover only a short time frame and do not consider dynamic effects. I show that introducing credit creates a boom in...

This paper estimates a dynamic model of durable and non-durable consumption choice and default behavior in an economy where risky borrowing is allowed and bankruptcy protection is regulated by law. I exploit the substantial difference in the generosity of bankruptcy exemptions across the U.S....

The paper examines the evolution of consumption patterns in Organization for Economic Co-operation and Development (OECD) countries from 1985 to 1999. Estimation of demand function parameters uncovered consistent evidence that differences in consumption patterns have recently diminished between...

Consumption is partly a social activity, yet most studies of consumer behavior treat households in isolation. We investigate familial relationships in consumption patterns using a sample of parents and their children from the Panel Study of Income Dynamics. We find a positive and statistically...
