Knowledge that Transforms

We use the practice of employee option repricing to investigate how shareholder involvement in firm compensation policies affects the quality of firm governance. We find that a 2003 reform that empowered shareholders to approve or reject repricing proposals led to value increases in previous repricers. The likelihood of repricing becomes less sensitive to poor manager performance, but remains similarly sensitive to bad luck, after the reform. Average post-repricing changes in firm performance are positive only after the reform. Overall, our results suggest that shareholder empowerment improves the governance of repricing and can transform repricing into a value-creating tool.

We show that the cross-sectional dispersion of conditional foreign exchange (FX) correlation is countercyclical and that currencies that perform badly (well) during periods of high dispersion yield high (low) average excess returns. We also find a negative cross-sectional association between average FX correlations and average option-implied FX correlation risk premiums. Our findings show that while investors in spot currency markets require a positive risk premium for exposure to high dispersion states, FX option prices are consistent with investors being compensated for the risk of low dispersion states. To address our empirical findings, we propose a no-arbitrage model that features unspanned FX correlation risk.

We provide new empirical evidence that world currency and U.S. stock variance risk premiums have nonredundant and significant predictive power for the appreciation rates of 22 with respect to the U.S. dollar, especially at the four-month and one-month horizons, respectively. The heterogeneous exposures of currencies to the currency variance risk premium are systematically rising along the line of inflation risk. We rationalize these findings in a consumption-based asset pricing model, with local consumption uncertainty and global inflation uncertainty characterized, respectively, by the stock and currency variance risk premiums.

We construct a text-based measure of uncertainty starting in 1890 using front-page articles of the Wall Street Journal. News implied volatility (NVIX) peaks during stock market crashes, times of policy-related uncertainty, world wars, and financial crises. In US postwar data, periods when NVIX is high are followed by periods of above average stock returns, even after controlling for contemporaneous and forward-looking measures of stock market volatility. News coverage related to wars and government policy explains most of the time variation in risk premia our measure identifies. Over the longer 1890–2009 sample that includes the Great Depression and two world wars, high NVIX predicts high future returns in normal times and rises just before transitions into economic disasters. The evidence is consistent with recent theories emphasizing time variation in rare disaster risk as a source of aggregate asset prices fluctuations.

We explore the link between credit and equity markets by considering the informational content of the term structure of credit spreads. A shallower credit term structure predicts decreases in default risk and increases in future profitability, as well as favorable earnings surprises. Further, the slope of the credit term structure negatively predicts future stock returns. While systematic slope risk is priced, information diffusion from the credit market to equities, particularly in less visible stocks, plays an additional role in accounting for return predictability from credit slopes. That is, such predictability is less evident in stocks with high institutional ownership, analyst coverage, and liquidity, and vice versa.

Capital utilization and market power crucially affect asset prices in an economy exposed to shocks that improve real investment opportunities through capital-embodied technological innovations. We embed these two mechanisms in a standard general equilibrium model and show that (i) the price of risk for investment shocks is negative under fixed capital utilization, but positive under sufficiently flexible capital utilization, and (ii) the equity return exposure to investment shocks is negative under perfect competition, but positive under high market power. We further show that, high market power, persistent components in technology growth, and a strong preference for early resolution of uncertainty are jointly important to quantitatively match the observed equity risk premium.

Independent technological glitches forced two separate trading halts on different U.S. exchanges during the week of July 6, 2015. During each halt, all other exchanges remained open. We exploit exogenous variation provided by this unprecedented coincidence, in conjunction with a proprietary data set, to identify the causal impact of Designated Market Maker (DMM) participation on liquidity. When the voluntary liquidity providers on one exchange were removed, liquidity remained unchanged; when DMMs were removed, liquidity decreased market-wide. We find evidence consistent with the idea that these DMMs, despite facing only mild formal obligations, significantly improve liquidity in the modern electronic marketplace.
