Good disclosure, bad disclosure

Journal of Financial Economics 2019 131(1), 118-138 open access
We study real-efficiency implications of disclosing public information in a model with multiple dimensions of uncertainty where market prices convey information to a real decision maker. Paradoxically, when disclosure concerns a variable that the real decision maker cares to learn about, disclosure negatively affects price informativeness, and in markets that are effective in aggregating private information, this negative price-informativeness effect can dominate so that better disclosure negatively impacts real efficiency. When disclosure concerns a variable that the real decision maker already knows much about, disclosure always improves price informativeness and real efficiency. Our analysis has important empirical and policy implications for different contexts such as disclosure of stress test information and regulation of credit ratings.

Patent trolls and startup employment

Journal of Financial Economics 2019 133(3), 708-725
We analyze how frivolous patent infringement claims made by nonpracticing entities (NPEs, or “patent trolls”) affect startups’ ability to grow and create jobs, innovate, and raise capital. Our identification strategy exploits the staggered adoption of anti-troll laws in 32 US states. The laws lead to a 4.4% increase in employment at high-tech startups—an increase driven by IT firms, a frequent target of NPEs. Increased access to financing, both venture capital and patent-backed lending, is a key channel driving our findings. Measures aimed at curbing the threat posed by NPEs can thus help reduce the real and financing frictions faced by startups.

In search of preference shock risks: Evidence from longevity risks and momentum profits

Journal of Financial Economics 2019 133(1), 225-249
Time-preference shocks affect agents’ preferences for assets with different durations. We consider longevity risk as a source of time-preference shocks and model it in the recursive preferences setting. This implies a consumption-based three-factor model, including longevity risk, consumption growth rate, and the market portfolio, where longevity has a negative price of risk. Empirically, this model explains many well-known cross-sectional portfolios. Notably, we find that longevity risk and the momentum factor share a common business cycle component, i.e., short-run consumption risks. Prior winners (losers) provide hedging against mortality (longevity) risk and thus have higher (lower) expected returns, because winners have higher dividend growth and shorter equity durations than losers. Time-varying longevity risk captures most momentum profits over time, including the large momentum crashes observed in the data.

Firms’ innovation strategy under the shadow of analyst coverage

Journal of Financial Economics 2019 131(2), 456-483
We study the effect of analyst coverage on firms’ innovation strategy and outcome. Using data of US firms from 1990 to 2012, we find evidence that an increase in financial analysts leads firms to cut research and development expenses, acquire more innovative firms, and invest in corporate venture capital. We attribute the first result to the effect of analyst pressure and the others to the informational role of analysts. We also find that financial analysts encourage firms to make more efficient investments related to innovation, which increases their future patents and citations and influences the novelty of their innovations.

Liquidity windfalls: The consequences of repo rehypothecation

Journal of Financial Economics 2019 133(1), 42-63
This paper presents a model of repo intermediation in which dealers intermediate secured financing between lenders and borrowers using the same collateral. Lenders are insulated from dealers through their repo’s collateral, but borrowers are exposed to dealers through the loss of their collateral. This makes lenders’ repo terms insensitive to dealers’ default, while borrowers’ repo terms are not. The model shows that when repos serve to intermediate collateral, haircuts are negative. This paper explains the difference in haircuts between the bilateral and tri-party repo market and the different run dynamics observed across these markets during the financial crisis.

Are lemons sold first? Dynamic signaling in the mortgage market

Journal of Financial Economics 2019 132(1), 1-25
A central result in the theory of adverse selection in asset markets is that informed sellers can signal quality and obtain higher prices by delaying trade. This paper provides some of the first evidence of a signaling mechanism through trade delays using the residential mortgage market as a laboratory. We find a strong relationship between mortgage performance and time to sale for privately securitized mortgages. Additionally, deals made up of more seasoned mortgages are sold at lower yields. These effects are strongest in the “Alt-A” segment of the market, where mortgages are often sold with incomplete hard information, and in cases where the originator and the issuer of mortgage-backed securities are not affiliated.

Inferring volatility dynamics and risk premia from the S&P 500 and VIX markets

Journal of Financial Economics 2019 131(3), 593-618 open access
We estimate a flexible affine model using an unbalanced panel containing S&P 500 and VIX index returns and option prices and analyze the contribution of VIX options to the model’s in- and out-of-sample performance. We find that they contain valuable information on the risk-neutral conditional distributions of volatility at different time horizons, which is not spanned by the S&P 500 market. This information allows enhanced estimation of the variance risk premium. We gain new insights on the term structure of the variance risk premium, present a trading strategy exploiting these insights, and show how to improve S&P 500 return forecasts.

Expectation and duration at the effective lower bound

Journal of Financial Economics 2019 134(3), 736-760 open access
With risk-averse arbitrageurs and an effective lower bound (ELB) on nominal rates, nonlinear interactions among short-rate expectations, bond supply, and term premia emerge in equilibrium. These interactions, which are absent from affine models, help explain the observed behavior of the yield curve near the ELB, including evidence about unconventional monetary policy. The impact of both short-rate expectations and bond supply are attenuated at the ELB. However, in simulations of the post-crisis experience in the U.S., shocks to investors’ duration-risk exposures have much smaller effects than shocks to the anticipated path of short rates. The latter shocks matter, in part, because of the reduction in interest-rate volatility associated with a longer expected stay at the ELB—a novel channel of unconventional policy.

Manager sentiment and stock returns

Journal of Financial Economics 2019 132(1), 126-149
This paper constructs a manager sentiment index based on the aggregated textual tone of corporate financial disclosures. We find that manager sentiment is a strong negative predictor of future aggregate stock market returns, with monthly in-sample and out-of-sample R2s of 9.75% and 8.38%, respectively, which is far greater than the predictive power of other previously studied macroeconomic variables. Its predictive power is economically comparable and is informationally complementary to existing measures of investor sentiment. Higher manager sentiment precedes lower aggregate earnings surprises and greater aggregate investment growth. Moreover, manager sentiment negatively predicts cross-sectional stock returns, particularly for firms that are difficult to value and costly to arbitrage.

Do firms issue more equity when markets become more liquid?

Journal of Financial Economics 2019 133(1), 64-82 open access
Using quarterly data on initial public offerings (IPOs) and seasoned equity offerings (SEOs) for 37 countries from 1995 to 2014, we show that changes in equity issuance are positively related to lagged changes in aggregate local stock market liquidity. This relation is as economically significant as the well-known relation between equity issuance and lagged stock returns. It survives the inclusion of proxies for market timing, capital market conditions, growth prospects, asymmetric information, and investor sentiment. Changes in liquidity are less relevant for issuance by firms with greater financial pressures and by firms in less financially developed countries.
