few lags have trouble detecting predictability of log dividend growth because predictability is spread over many periods. Unfortunately, predictability of log dividend growth is not robust to subsamples,and it seems unwise to rely too much on the estimates given that the entire sample includes only five non-overlapping observations.

That Is Not My Dog: Why Doesn't the Log Dividend-Price Ratio Seem to Predict Future Log Returns or Log Dividend Growths?
Abstract
Campbell and Shiller’s “accounting identity” implies that changes in the log dividend-price ratio must predict either future returns or future log dividend growth. However, neither quantity seems to be predictable — a well-known puzzle in the literature. We examine this puzzle step-by-step from theoretical derivation through empirical testing. Stationarity of the log dividend-price ratio is an important assumption behind the accounting identity, but Campbell and Shiller’s test justifying this assumption does not make sense, and a corrected test does not reject non-stationarity. Nonetheless, a truncated accounting identity works reasonably well in the existing sample, and we find that the log dividend-price ratio predicts log dividend growth, not returns. Traditional tests using one or afew lags have trouble detecting predictability of log dividend growth because predictability is spread over many periods. Unfortunately, predictability of log dividend growth is not robust to subsamples,and it seems unwise to rely too much on the estimates given that the entire sample includes only five non-overlapping observations.
Expected Stock Returns and the Correlation Risk Premium
Abstract
We document that information about the comovement of individual stocks, jointly extracted from index options and individual stock options, can be used to predict future market excess returns for horizons of up to 1 year, both in-sample and out-of-sample. The predictive power is incremental to that of risk measures exclusively based on the marginal distribution of the market, including (semi)variances and their risk premiums.~We attribute this predictability to the ability of expected correlation to capture expected variations in idiosyncratic risk and in the cross-sectional dispersion in systematic risk. A novel extension of the contemporaneous-beta approach significantly improves out-of-sample predictability.Discussant(s)
