Dispersion in firm‐level growth rates rises during recessions. To date, this has been explained through mechanisms on the firms' side of the economy. In this paper, I show that countercyclical dispersion can arise from changes on the demand side of the economy. Using retail data I find that during recessions demand elasticity rises, the dispersion of firms' growth rates increases, and this increase is larger in markets where the change in consumer behavior is the strongest. I develop a business cycle model with heterogeneous firms and frictions in product markets that highlights the relationship between consumer behavior and firm volatility.
