Visibility bias in the transmission of consumption beliefs and undersaving

Authors: Han, Hirshleifer, Walden

Abstract

We model visibility bias in the social transmission of consumption behavior. When consumption is more salient than non-consumption, people perceive that others are consuming heavily, and infer that future prospects are favorable. This increases aggregate consumption in a positive feedback loop. A distinctive implication is that disclosure policy interventions can ameliorate undersaving. In contrast with wealth-signaling models, information asymmetry about wealth reduces overconsumption. The model predicts that saving is influenced by social connectedness, observation biases, and demographic structure; and provides a novel explanation for the dramatic drop in savings rates in the US and several other countries in recent decades.
