Durables and the Marginal Propensity to Spend

Durables represent a large share of households' marginal propensity to spend (MPX). We develop a quantitative model of spending that takes durables into account and matches a rich set of empirical regularities simultaneously. Scaling the response of nondurables provides a poor approximation of the MPX on durables when it comes to its distribution in the population, its persistence over time, and its cyclicality. As an application, we study how the MPX varies with the size of stimulus checks and find that it declines more slowly compared to a model of purely nondurable spending. (JEL D11, E21, E32, E62, G51)
