Dynamic factor models of consumption,hours and income

This paper addresses two questions in the economics of intertemporal choice. First, what are the key factors that drive fluctuations in income and what are the time paths of their effects? Second, how do consumers respond to these factors? We answer these questions by estimating dynamic factor models of consumption, hours, wages, unemployment, and income that account for measurement error and the fact that variables used in the study are measured at different time intervals and/or are aggregates for the calendar year. We pay special attention to a dynamic factor representation of a joint life cycle model of consumption and labour supply, which permits us to quantify the effect of wages, unemployment, and other factors on the marginal utility of income as well as to estimate the substitution effects of wage changes on labour supply and consumption.
