Macroeconomic Expectations And State Dependent Factor Returns PDF Download

In this paper we study empirically the implications of macroeconomic disagreement for the time variation in bond market risk premia. If there is a source of heterogeneity in the belief structure of the economy then differences in beliefs can affect equilibrium asset prices, and the dynamics of disagreement may generate a source of predictable variation in excess bond returns. Using survey data on macroeconomic forecasts of fundamentals spanning interest rates, real aggregates and inflation variables at different horizons we propose a new empirically observable proxy to aggregate macroeconomic disagreement and find a number of novel results. Firstly, consistent with a general equilibrium model, heterogeneity affects the price of risk so that a single factor proxy for disagreement forecasts bond returns with R2 between 15%- 20%. Secondly, by allowing for a time-varying price of risk proportional to disagreement, we substantially improve the forecasting power of a standard affine model for expected returns. This result is carried over to Fama-Bliss regressions where we find that the information contained in the slope of the forward curve regarding expected returns versus expected changes in short rates is state-dependant. Thirdly, while the predictive content of the return forecasting factor (Cochrane and Piazzesi (2005)) is cut dramatically in the 2008 financial crisis, disagreement is largely unaffected. We interpret this result in terms of Fed interventions which may have distorted the shape of the forward curve, removing price based information on expected returns. Finally, we show that the information contained in agents' belief structure of the economy is different from that contained in macroeconomic aggregates, suggesting that a key determinant for bond returns is the joint subjective uncertainty surrounding the real economy, inflation, and monetary policy.
