内容摘要：This study provides a supply-side model of options markets to illustrate how options pricing uncertainty affects moment risk premia. The model is based on a microstructure such that a representative market maker dynamically replicates option prices, hedges risky positions, and seeks the minimum variance in duplicating errors. Unlike previous studies exogenously applying the underlying asset’s pricing kernel, our model starts with options’ hedging uncertainty, the pricing kernel that distinguishes options from ordinary equities, and can explain more than 45% of the variation in market risk-neutral moments. We also provide insights into the effects of market friction and nonnormality on moment risk premia and implied volatility curves.
