Joint Implied Willow Tree: An Approach for Joint S&P 500/VIX Calibration
ABSTRACT Since the inception of Volatility Index (VIX) options trading, academic literature has persistently sought accurate methods for jointly calibrating the prices of the S&P 500 index (SPX) and VIX options. This study introduces a novel nonparametric approach, called the joint implied willow tree (JIWT) method, aimed at resolving this joint ...

The Term Structure of Credit Default Swap Spreads and the Cross Section of Options Returns
ABSTRACT This paper, using the natural logarithmic form credit default swap (log CDS) slope, examines the variation in cross‐sectional 1‐month ATM delta‐hedged straddle returns. Our analysis reveals that the log CDS slope significantly and positively predicts these returns, even when accounting for several key volatility mispricing factors.

Abstract Operating flexibility supports a firm's resilience strategy during challenging times by enabling them to promptly cut down operating costs associated with unproductive resources. We employ a real options model to formalize this insight. Our empirically grounding analytics motivate a firm‐level proxy for downscale operating flexibility (FLEX ...
