Abstract: This study presents an analysis of the impact of asset price bubbles on a liquidity risk measure, the liquidity risk option premium ('LROP'). We present a styled model of asset price bubbles in continuous time, and perform a simulation experiment of a stochastic differential equation ('SDE') system for the asset value through a constant elasticity of variance ('CEV') process. Comparing bubble to non-bubble economies, it is shown that asset price bubbles may cause an firm's traditional risk measures, such as value-at-risk ('VaR') to decline, due to an increase in the right skewness of the value distribution, which results in the LROP to decline and therefore an underpricing of liquidity risk.
