We model demand-pressure effects on option prices. The model shows that demand pressure in one option contract increases its price by an amount proportional to the variance of the unhedgeable part of the option. Similarly, the demand pressure increases the price of any other option by an amount...

This paper investigates informed trading on stock volatility in the option market. Using a unique data set from the Chicago Board Options Exchange, we construct non-market maker net demand for stock volatility from the trading volume of individual equity options. We find that this volatility...

We find strong evidence of information transmission from the options market to underlying stock prices. Taking advantage of a unique dataset from the Chicago Board Options Exchange, we construct put to call volume ratios for underlying stocks, using only volume initiated by buyers to open new...

The question of whether and to what extent option trading impacts underlying stock prices has been a focus of intense interest since options began exchange-based trading in 1973. Despite considerable effort, no convincing evidence for a pervasive impact has been produced. A recent strand of...

We model the demand-pressure effect on prices when options cannot be perfectly hedged. The model shows that demand pressure in one option contract increases its price by an amount proportional to the variance of the unhedgeable part of the option. Similarly, the demand pressure increases the...

There are a number of circumstances in finance where it is useful to estimate diffusion processes conditional on some event. In this paper, we develop the theoretical and numerical tools necessary to perform conditional estimation of diffusion processes within a generalized method of moments...

This paper examines optimal capital structure choice using a dynamic capital structure model that is calibrated to reflect actual firm characteristics. The model uses contingent-claim methods to value interest tax shields, allows for reorganization in bankruptcy, and maintains a long-run target...
