Abstract

We quantitatively evaluate the effectiveness of a consumption tax and transfer pro- gram as insurance against idiosyncratic earnings risk. Our framework is a heterogeneous- agent, incomplete-market model with idiosyncratic wage risk and indivisible labor. The model is calibrated to the U.S. economy. We find a weak insurance effect of the transfer program. Extending the transfer system from the current scale raises consumption un- certainty, which increases aggregate savings and reduces the interest rate. Furthermore, consumption inequality shows a small decrease.
