We develop a tractable dynamic model of an index option market maker with limited capital and characterize how option prices depend on inventory risk and market maker wealth. The risk averse market maker absorbs positive demand by end users and requires a more negative variance risk premium when...

Consistent with models in which intermediaries absorb net demand pressure from end-users and respond by changing prices, net option demand is positively related to option prices in the market for VIX puts and VIX calls. These findings are consistent with existing results for S&P 500 index (SPX)...

Standard option valuation models leave no room for option illiquidity premia. Yet we find the risk-adjusted return spread for illiquid over liquid equity options is 3.4 percent per day for at-the-money calls and 2.5 percent for at-the-money puts. These premia are computed using option...

Options on crude oil futures are the most actively traded commodity options. We develop a class of computationally efficient discrete-time jump models that allow for closed-form option valuation, and we use crude oil futures and options data to investigate the economic importance of jumps and...

The cross-section of options holds great promise for identifying return distributions and risk premia, but estimating dynamic option valuation models with latent state variables is challenging when using large option panels. We propose a particle MCMC framework with a novel filtering approach...
