Hand-to-Mouth Consumers and Asset Prices

Abstract : Many consumers seem to lead a hand-to-mouth existence: they simply consume their current income. This may be the result of unsophisticated behavior (non-optimizing, or ‘rule-of-thumb’ consumers), or the reflection of an inability to trade in asset markets due to infinite transactions costs. The objective of this paper is to explore, in a very simple model, the implications for equilibrium asset prices of the presence of hand-to-mouth consumers. I will establish that allowing for the existence of hand-to-mouth consumers contributes, under plausible assumptions, to the resolution of the equity premium puzzle’ and of the riskfree rate puzzle. As a consequence, the same phenomenon - hand-to-mouth consumption - which Campbell and Mankiw (1989) have shown to be crucial to the description of the time-series behavior of aggregate consumption has the potential of explaining asset market data (...).
