Welfare and Spending Effects of Consumption Stimulus Policies
Using a heterogeneous agent model calibrated to match measured spending dynamics over four years following an income shock (Fagereng, Holm, and Natvik (2021)), we assess the effectiveness of three fiscal stimulus policies employed during recent recessions. Unemployment insurance (UI) extensions are the clear “bang for the buck” winner, especially when effectiveness is measured in utility terms. Stimulus checks are second best and have the advantage (over UI) of being scalable to any desired size. A temporary (two-year) cut in the rate of wage taxation is considerably less effective than ...

Consumption Heterogeneity: Micro Drivers and Macro Implications
This paper explores the microfoundations of consumption models and quantifies the macro implications of consumption heterogeneity. We propose a new empirical method to estimate the response of consumption to permanent and transitory income shocks for different groups of households. We then apply this method to administrative data from Denmark. The large sample size, along with detailed household balance sheet information, allows us to finely divide the population along relevant dimensions. We find that households that stand to lose from an interest rate hike are significantly more responsive ...

Income Shocks and Their Transmission into Consumption
This paper reviews the economics literature of, primarily, the past 20 years that studies the link between income shocks and consumption fluctuations at the household level. We identify three broad approaches through which researchers estimate the consumption response to income shocks: (1) structural methods in which a fully or partially specified model helps identify the consumption response to income shocks from the data, (2) natural experiments in which the consumption response of one group that receives an income shock is compared with another group that does not, and (3) elicitation ...
