Habits, Sentiment and Predictable Income in

This paper explores whether habit formation in the representative agent's preferences can explain two failures of the standard permanent income model: the sensitivity to lagged consumer sentiment, and to predictable changes in income. I show that in a habit formation model, the sensitivity of consumption to predicted income can be largely reinterpreted as a sluggish response to news. Moreover, the sensitivity of consumption to sentiment reflects the serial correlation in consumption growth generated by habits. The estimated model predicts an immediate (first-quarter) MPC out of a permanent tax cut of only about 30%
