Recent work by Engle and Lee (1999) shows that allowing for long-run and short-run components greatly enhances a GARCH model’s ability fit daily equity return dynamics. Using the risk-neutralization in Duan (1995), we assess the option valuation performance of the Engle-Lee model and compare...

This paper presents a new model for the valuation of European options, in which the volatility of returns consists of two components. One of these components is a long-run component, and it can be modeled as fully persistent. The other component is short-run and has a zero mean. Our model can be...

Based on a rational option pricing framework that incorporates short-selling and margin-trading constraints in the stock market, we present evidence that Chinese warrant prices, which are regarded as bubbles in the previous literature, can be explained by a new option pricing model. Based on the...

This paper conducts a first look into the regulated Bitcoin options market in the United States. We find bitcoin options to be ten times more illiquid than stock options, as measured by bid-ask spreads. The illiquidity significantly affects bitcoin options pricing: Given that investors are on...

This paper studies Chinese warrant price deviation. By observing “asymmetric price error” phenomena, we propose that the rational hedging and speculation motivation is one important cause for warrant price deviations. Investors do not speculate irrationally under the resale motivation all...
