This is a short survey on consumption theory. Consumption is important to both fluctuation and growth. In addition, consumption introduces some important issues involving financial markets and portfolio decisions. We will describe consumption decisions in a dynamic context. Uncertainty about...

In 1960, Working noted that time aggregation of a random walk induces serial correlation in the first difference that is not present in the original series. This important contribution has been overlooked in a recent literature analyzing income and consumption in panel data. I examine Blundell,...

Consumption growth is predictable, a basic violation of the permanent-income hypothesis. This paper examines three possible explanations: rule-of-thumb behavior, in which households allow consumption to track per-period income flows rather than permanent income; habit persistence; and...

In the quantitative macroeconomics literature, single agent models are widely used to explain ``per-adult equivalent'' data, which are obtained at the household level. In this paper we suggest a simple framework to understand the sources of bias when these models are used to make predictions for...

In the quantitative macro literature, single agent models are heavily used to explain "per-adult equivalent" household data. In this paper, we study differences between consumption predictions from a single agent model and "adult equivalent" consumption predictions from a model where household...

Although the link between household size and consumption has a strong empirical support, there is no consistent way in which demographics are dealt with in standard life-cycle models. We study the relationship between the predictions of the Single Agent model (the standard in the literature)...

How can public pension systems be reformed to ensure fiscal stability in the face of increasing life expectancy? To address this pressing open question in public finance, we use micro data to estimate a structural life-cycle model of individuals' employment, retirement and consumption decisions....

The downturn in economic activity in the U.S. that began in December 2007 (as determined by researchers with the National Bureau of Economic Research) has been noticeably deeper and has already lasted considerably longer than the prior two recessions - those beginning in July 1990 and in March...

We study the trend in household income uncertainty using a novel approach that measures income uncertainty as the variance of forecast errors at each future horizon separately without imposing parametric restrictions on the underlying income shocks. We find that household income uncertainty has...

We use repeated cross-sections of the Survey of Consumer Finances (SCF) to study the effect of self-reported transitory income shocks on household food spending. The self-reported shocks in the SCF are derived from survey questions about the gap between actual and "normal" income. This approach...
