This paper explains and extends my 2002 paper. It presents a return factor of illiquid-minus-liquid stocks, called IML, which provides a time series of the illiquidity premium. The risk-adjusted predicted return on IML is lower in the period that follows my 2002 paper but it is still...

This paper reviews research on the effects of different measures of liquidity on asset prices. The foundation is the pricing of liquidity as an asset characteristic that began with the theoretical model and empirical evidence of Amihud and Mendelson (1986). The positive relation between expected...

We test the pricing of the conditional systematic risk (β) of IML, a traded liquidity factor of the return premium on illiquid-minus-liquid stocks, with its risk premium varying over time. We find a positive and significant risk premium on conditional IML β, which rises in times of financial...

This paper presents a liquidity factor IML, the return on illiquid-minus-liquid stock portfolios. The IML, adjusted for the common risk factors, measures the illiquidity premium whose annual alpha is about 4% over the period 1950-2012. I then test whether the systematic risk (β) of IML is...
