The high cost of capital for firms conducting medical research and development (R&D) has been partly attributed to the government risk facing investors in medical innovation. This risk slows down medical innovation because investors must be compensated for it. We propose new and simple financial...

We examine stock return predictability of "Out-of-The-Money (OTM) put-to-OTM call trading volume ratio" (OTMPC). Our numerical analysis predicts that informed investors hardly write OTM options because the leverage effect is not sufficient to compensate for transaction costs. OTMPC, thus,...

Although the environmental, social, and governance (ESG) has gained increasing attention among investors, the extent to which ESG is compensated systematically in the market remains to be investigated. On the outperformance of responsible investing (RI) which incorporates ESG into investment...

We show that the presence of high frequency trading (HFT) has significantly mitigated the frequency and severity of end-of-day price dislocation, counter to recent concerns expressed in the media. The effect of HFT is more pronounced on days when end of day price dislocation is more likely to be...

American call and put options on the S&P 500 index futures that violate the stochastic dominance bounds of Constantinides and Perrakis (2007) over 1983-2006 are identified as potentially profitable investment opportunities. Call bid prices more frequently violate their upper bound than put bid...

Understanding volatility transmissions amongst commodity futures and the stock market is integral for risk management. In this study, we investigate the time-varying volatility spillovers amongst nine major commodity futures and the US S\&P 500 index across three decades. We also analyse the...

Using a semi-supervised topic model on 7,000,000 New York Times articles spanning 160 years, we test whether topics of media discourse predict future stock and bond market returns to test rational and behavioral hypotheses about market valuation of disaster risk. Focusing on media discourse...

We explore the term structures of claims to a variety of cash flows: U.S. government bonds (claims to dollars), foreign government bonds (claims to foreign currency), inflation-adjusted bonds (claims to the price index), and equity (claims to future equity indexes or dividends). Average term...

This paper presents empirical evidence that the corporate bond market is forward looking with respect to volatility. I use the Merton (1974) model to calculate a measure of implied volatility from corporate bond yield spreads. I find that corporate bond transaction prices contain substantial...

Suppose a fund manager uses predictors in changing port-folio allocations over time. How does predictability translate into portfolio decisions? To answer this question we derive a new model within the Bayesian framework, where managers are assumed to modulate the systematic risk in part by...
