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...

This paper explores a rational economic explanation for the much discussed credit card debt puzzle. We set-up and simulate a generalization of the buffer-stock consumption model with longterm revolving debt contracts. In line with US credit card law, lenders can always deny households access to...

This paper studies consumption and savings decisions of Danish households before and during the financial crisis as well as in the more recent years characterized by negative policy rates. While all household groups decreased their consumption ratios immediately in response to the financial...

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...
