This paper proposes a pure-exchange economy with three key ingredients: habit formation, stochastic moments of aggregate consumption, and a small degree of heterogeneity in risk aversion consistent with empirical data. We obtain closed formulas for many equilibrium quantities, including the moments of stock returns and individual portfolios. The proposed framework explains simultaneously the main features of stock returns – like cyclicality, persistence and predictability – as well as the counter-cyclical dynamics of the trading volume and its correlation with stock returns. In addition, we provide new testable implications concerning the dynamic behavior of the cross-sectional consumption/portfolio distribution over the business cycle.
