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...

We develop an Arbitrage Pricing Theory framework extension to study the pricing of squared returns/volatilities. We analyze the interplay between factors at the return level and those in idiosyncratic variances. We confirm the presence of a common idiosyncratic variance factor, but do not find...

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...

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...
