This paper uses the consumption Euler equation to derive a decomposition of consumption growth into four sources. These are new information and three sources of predictable consumption growth: intertemporal substitution, changes in the preferences for consumption, and incomplete markets for consumption insurance. Using data on the expenditures of households, we implement the decomposition for t...

This paper examines how aversion to risk and aversion to intertemporal substitution determine the strength of the precautionary saving motive in a two-period model with Selden/Kreps-Porteus preferences. For small risks, we derive a measure of the strength of the precautionary saving motive which generalizes the concept of “prudence” introduced by Kimball [12]. For large risks, we show that decr...

The U.S. national saving rate has been declining since the 1960s while the share of consumption in output has been increasing. We explore if a standard growth model can explain the secular movements observed in this time period. Our quantitative findings indicate that the standard neoclassical growth model is able to generate saving rates and consumption that are remarkably similar to the data ...

in this paper, the behavior of saving and consumption has been considered in ramsey – cass- koopmans model’s framework. our purpose was investigation of dynamics of these variables and analysis of their response to other parameter and variable variations. so, we made lagrangian function subject to some restrictions and euler equations and other steady state path equations. and then, we have cal...
