Transaction Costs and Asset Valuation Available to Purchase

We suggest the method of evaluation of illiquid assets on the market in the presence of proportional transaction costs by using two consumption/investment models. We study an investor's implicit evaluation of an illiquid asset whose trading incurs a proportional transaction cost. We show that the investor assigns an implicit value between the bid and ask price and uses it for his investment and/or consumption decisions. We also show that the implicit value is an increasing function of the investor's liquidity ratio, which is a measure of liquidity of the investor's asset holdings.
