Using subjective income expectations to test for excess sensitivity of consumption to predicted income growth

We test for precautionary saving and excess sensitivity of consumption to predicted income growth using a 1989-1993 panel survey of Italian households that has measures of subjective income and inflation expectations. These expectations provide a powerful instrument for predicting income growth. The empirical specification controls for predictable changes in labor supply and allows a fairly general specification for the stochastic structure of the forecast error. We find that consumption growth is positively correlated with the expected variance of income and uncorrelated with predicted income growth. Overall, the results support the precautionary saving model. (C) 2000 Elsevier Science B.V. All rights reserved. JEL classification: E21.
