Subjective Cash Flow and Discount Rate Expectations [June 2021] [ Journal of Finance] [Working paper version](with Sean Myers) Data
Why do stock prices vary? Using survey forecasts, we find that cash flow growth expectations explain most movements in the S&P 500 price-dividend and price-earnings ratios, accounting for at least 93% and 63% of their variation. These expectations comove strongly with price ratios, even when price ratios do not predict future cash flow growth. In comparison, return expectations have low volatility and small comovement with price ratios. Short-term, rather than long-term, expectations account for most price ratio variation. We propose an asset pricing model with beliefs about earnings growth reversal that accurately replicates these cash flow growth expectations and dynamics.
Survey expectations of dividend growth (blue) vary substantially over time and strongly comove with the S&P 500 price-dividend ratio (red). Survey expectations of returns (green) are relatively flat over time and have low comovement with the price-dividend ratio.
Are stock valuation ratios mainly informative about future earnings growth or future returns? Using a variance decomposition, we find that over 70% of cross-sectional variation in price-earnings ratios is reflected in cross-sectional differences in future returns, while less than 30% is reflected in differences in future earnings growth. The lack of predictable earnings growth implies returns are much more predictable than previously estimated. This is because, empirically, valuation ratios primarily predict future returns and only modestly predict future earnings growth. Additionally, changes in predicted returns are more important than changes in predicted earnings growth for explaining innovations in price-earnings ratios and current realized returns. We reconcile these results with previous literature which has found a strong relation between prices and future profitability. Our results support models in which the cross-section of stock valuation ratios is driven mainly by discount rates or mispricing rather than future earnings growth.
Cross-sectional differences in stock P/E ratios are mainly explained by expensive stocks having lower future returns and higher future P/E ratios rather than higher future earnings growth. As the horizon increases, the importance of the future P/E ratio declines and is largely replaced by a bigger role for future returns.
The Effect of Buybacks on Capital Allocation [March 2022]
This paper studies the macroeconomic effects of a 1982 SEC rule that made share buybacks a viable alternative to dividends for paying out funds to shareholders. I propose a quantitative model of heterogeneous firms with dividend adjustment costs and a manager-shareholder conflict, matched to micro data on US corporations’ cash flow statements. The flexibility of buybacks reduces capital misallocation. This is not only because investors can more easily shift resources to more productive firms, but also because stock prices become more responsive to productivity and thus help align incentives of managers and shareholders. This "stock price channel" allows the model to not only account for a decline in investment and increase in productivity, but also the increase in corporate cash holdings over the last decades.
When Do Subjective Expectations Explain Asset Prices? [January 2022] [R&R at RFS] (with Sean Myers)
We present a method for determining whether errors in expectations explain asset pricing puzzles without imposing assumptions about the mechanism of the error. Using accounting identities and survey forecasts, we find that errors in expected long-term inflation and short-term nominal earnings growth explain price variation, return predictability, and the rejection of the expectations hypothesis for aggregate stock and bond markets. Errors in expected short-term inflation and long-term nominal earnings growth play no role. The relevant errors are consistent with mistakes about both the persistence of forecasted variables and the response to surprises. A fundamental extrapolation model successfully replicates these findings.
Survey expectations of long-term inflation are volatile, moving almost 1-1 with expectations of short-term inflation. In contrast, for survey expectations of S&P 500 nominal earning growth, almost of all of the movements occur in short-term expectations.
Employment Dynamics and Monetary Policy for Emerging Economies under Informality [October 2019] (with Stephen McKnight)
This paper investigates the role of labor informality in the propagation of transitory shocks and its implications for interest rate policy in preventing self-fulfilling inflation expectations. We develop a dynamic New Keynesian model where the size of the informal sector reacts to search and matching frictions in the formal sector, which can account for the observed behavior of formal and informal employment in Mexico. We show that informality reduces the volatility of aggregate consumption and employment, but investment volatility increases. While informality amplifies the propagation of demand shocks on inflation, it dampens the response of output, weakening the transmission mechanism of monetary policy to output. For interest-rate feedback rules that react to formal measures of inflation, we find that informality significantly restricts the ability of the Taylor principle to ensure determinacy. However, we show that determinacy can be restored when policy also responds to formal output.
