Housework and Fiscal Expansions

Available as: PDF

We build an otherwise-standard business cycle model with housework, calibrated consistently with data on time use, in order to discipline consumption-hours complementarity and relate its strength to the size of fiscal multipliers. We show that if substitutability between home and market goods is calibrated on the empirically relevant range, consumption-hours complementarity is large and the model generates fiscal multipliers that agree with the evidence. Hence, our analysis supports the relevance of consumption-hours complementarity for fiscal multipliers. However, we also find that explicitly modeling the home sector is more appealing than restricting to the consumption-leisure margin and/or to the preferences proposed by Greenwood, Hercowitz and Huffman (1988). A housework model can imply substantial complementarity, without low wealth effects contradicting the microeconomic evidence.
