Discrete-time option pricing with stochastic liquidity

M Leippold, S Schärer - Journal of Banking & Finance, 2017 - Elsevier
Classical option pricing theories are usually built on the law of one price, neglecting the
impact of market liquidity that may contribute to significant bid-ask spreads. Within the …
