Macroeconomic models often invoke consumption “habits” to explain the substantial persistence of aggregate consumption growth. But a large literature has found no evidence of habits in microeconomic datasets that measure the behavior of individual households. We show that the apparent...

We estimate the degree of amp;apos;stickinessamp;apos; in aggregate consumption growth (sometimes interpreted as reflecting consumption habits) for thirteen advanced economies. We find that, after controlling for measurement error, consumption growth has a high degree of autocorrelation, with a...

This paper argues that the versions of both permanent income and life-cycle theories which have recently become fashionable are inconsistent with the grossest features of cross-country and cross-section data on consumption and income. There is clear evidence that consumption and income growth...

This paper compares the dynamics of two general equilibrium models of endogenous growth in which agents have comparison utility.' In the inward-looking' economy, individuals care about how their consumption in the current period compares to their own consumption in the past (one way to describe...

"Buffer-stock" versions of the dynamic stochastic optimizing model of saving are now standard in the consumption literature. This paper builds theoretical foundations for rigorous understanding of the main characteristics of buffer stock models, including the existence of a target level of...

This paper examines the relationship between household balance sheets, consumer purchases, and expectations. We find few robust empirical relationships between balance sheet measures and spending, but we do find that unemployment expectations are robustly correlated with spending. We then...

Because efforts to explain international saving differentials using traditional economic variables have not been very successful (Bosworth, 1993), some economists have proposed that national saving differences reflect cultural differences. We attempt to test that hypothesis by using data from...
