英文文献：Illiquidity Premia in the Equity Options Market
英文文献作者：Peter Christoffersen,Ruslan Goyenko,Kris Jacobs,Mehdi Karoui
英文文献摘要：
Illiquidity is well-known to be a signi?cant determinant of stock and bond returns. We report on illiquidity premia in equity option markets. An increase in option illiquidity decreases the current option price and predicts higher expected option returns. This effect is statistically and economically signi?cant. It is robust across different empirical approaches and when including various control variables. The illiquidity of the underlying stock affects the option return negatively, consistent with a hedging argument: When stock market illiquidity increases, the cost of replicating the option goes up, which increases the option price and reduces its expected return.
