Fiscal Policy and MPC Heterogeneity

Abstract

We use responses to survey questions in the 2010 Italian Survey of Household Income and Wealth that ask consumers how much of an unexpected transitory income change they would consume. The marginal propensity to consume (MPC) is 48 percent on average. We also find substantial heterogeneity in the distribution, as households with low cash-on-hand exhibit a much higher MPC than affluent households, which is in agreement with models with precautionary savings, where income risk plays an important role. The results have important implications for predicting household responses to tax reforms and redistributive policies. (JEL D12, D14, E21, E62, H23, H24)
