The effect of liquidity on non-marketable securities

We generalize the prevailing theoretical models that estimate the discount on securities for lack of marketability, by considering the discrete trading frequency of the securities. The generalization shows that accounting for the illiquidity of securities may significantly reduce their non-marketability discount. Further, the method reconciles the approaches of Longstaff (1995) and Finnerty (2012a), which are special solutions of our method.
