Recent empirical evidence based on a linear framework tends to suggest that a Markovswitching version of the consumption-aggregate wealth ratio (cay MS ), developed to account for structural breaks, is a better predictor of stock returns than the conventional measure (cay) -a finding we confirm as well. Using quarterly data over 1952:Q1-2013:Q3, we however provide statistical evidence that the relationship between stock returns and cay or cay MS is in fact nonlinear. Then, given this evidence of nonlinearity, using a nonparametric Granger causality test, we show that it is in fact cay and not cay MS which is a stronger predictor of not only stock returns, but also volatility.JEL Codes: C32, C58, G10, G17
