We propose a structural model for durations between events and (a vector of) associated marks, using a multivariate Brownian motion. Successive passage times of one latent Brownian component relative to random boundaries define durations. The other, correlated, Brownian components generate the...

Risk-neutral traders executing derivative trades on behalf of portfolio managers maximize their expected profit compared to trading at pre-determined times by timing trades, using the quickly changing risk exposures of derivative baskets. The optimal order submission strategy is a sequence of...

Stock and options markets can disagree about a stock's value because of informed trading in options and/or price pressure in the stock. The predictability of stock returns based on this cross- market discrepancy in values is especially strong when accompanied by stock price pressure, and it does...

Estimation of risk-neutral (RN) moments is of great interest to both academics and practitioners. We study 1) the model-free measure of RN moments by Bakshi, Kapadia and Madan (2003); 2) RN moments that are used in the VIX and SKEW index by the Chicago Board Options Exchange; 3) nonparametric RN...

Time-varying leverage driven by common shocks to firm asset returns introduces a factor structure in idiosyncratic equity return volatilities (IVOL). In a standard dynamic capital structure model in which the CAPM holds for asset returns, we show that three factors explain the IVOL...
