We build a life-cycle model with earnings risk, liquidity constraints, and portfolio choice over tax-deferred and taxable assets to evaluate how household consumption changes in response to shocks to transitory anticipated income, such as the 2001 income tax rebate. Households optimally invest in tax-deferred assets, which are encumbered by withdrawal penalties, and exchange taxable precautionary savings for higher after-tax returns. The model predicts a higher marginal propensity to consume out of a rebate than is predicted by a standard frictionless life-cycle model. Liquidity-constrained households—with few financial assets or portfolios expensive to reallocate—consume a higher fraction of the rebates. (JEL D91, E21, G11, H24)
