Idiosyncratic income risk and aggregate fluctuations

We study how the presence of idiosyncratic income risk affects aggregate fluctuations in the absence of binding borrowing constraints and/or cyclical income risk. Its impact is shown to be captured by the response of a consumption-weighted average of individual consumption risk to aggregate shocks....

Sumario:We study how the presence of idiosyncratic income risk affects aggregate fluctuations in the absence of binding borrowing constraints and/or cyclical income risk. Its impact is shown to be captured by the response of a consumption-weighted average of individual consumption risk to aggregate shocks. We analyze two example economies—an endowment economy and a New Keynesian economy—and show that, under plausible calibrations, the impact of idiosyncratic income risk on aggregate fluctuations is quantitatively small since most of the changes in consumption risk are concentrated among poorer (low-consumption) households.
