- Abstract
- We study how sector-specific fiscal policy propagates in an economy with heterogeneous households and production networks. We develop a multisector New Keynesian model in which input-output linkages interact with differences in households’ marginal propensities to consume (MPCs). We show that fiscal multipliers depend on sectors’ positions in the production network, as network linkages reallocate income across households with heterogeneous consumption responses. We derive an intersectoral Keynesian cross and introduce an MPC-augmented network multiplier that jointly characterize the transmission of fiscal shocks. The interaction between heterogeneous consumption responses and production networks is non-additive: network linkages can either amplify or attenuate fiscal transmission depending on how income is redistributed across households. Fiscal policy is most effective when spending is directed toward labor-intensive, downstream sectors that employ a large share of high-MPC households. Using data from the Survey of Consumer Finances, we document substantial sectoral heterogeneity in household balance sheets and in the prevalence of hand-to-mouth households. Calibrating the model to the U.S. economy, we find sizable variation in sectoral fiscal multipliers and significant distributional effects of government spending.
