We study jump variance risk by jointly examining both stock and option markets. We develop a GARCH option pricing model with jump variance dynamics and a non-monotonic pricing kernel featuring jump variance risk premium. The model yields a closed-form option pricing formula and improves in...

A firm's patent-to-market (PTM) ratio refers to the percentage of a firm's market value that is attributable to its patent market value. A hedging portfolio based on PTM ratio generates a monthly return of 71 basis points. The CAPM cannot be rejected for firms with low PTM ratios, but is...

We provide plausibly identified evidence for the role of investor disagreement in asset pricing. Our natural experiment exploits the staggered implementation of EDGAR, which induces a reduction in investor disagreement with no accompanying changes in company fundamentals, disclosure quality, or...
