In this paper we model the evolution ofincome risk and consumption growth.We decompose the time series innovation of the income process intoits common and cohort-specific components. From these we compute conditional variances which are used as separate risk terms in a consumptiongrowthequation. U singalongtimeseriesofB ritishhouseholddatawe ndstrongevidenceofprecautionarysaving. Specically, afterallowing fordemographicand labourmarketstatus, there is an independent role for income risk in explaining consumption growth.
