This paper reviews and extends recent research on liquidity and asset pricing. We start by asking how can intrinsically-worthless fiat money be valued in equilibrium? The literature on which we build formalizes how money is valued for its liquidity when exchange is hindered by various frictions. Once one sees how money can be priced above its fundamental value, it is clear that many other assets can be, too, if they also convey liquidity. We study under which conditions money can be valued if assets have fundamental value, how the liquidity values of money and assets interact, and how they are affected by changes in parameters such as acceptability, pledgeability, or the type of the asset.
