Standard models of liquidity argue that the higher price for a liquid security reflects the future benefits that long investors expect to receive. We show that short-sellers can also pay a net liquidity premium if their cost to borrow the security is higher than the price premium they collect from selling it. We provide a model-free decomposition of the price premium for liquid securities into the net premiums paid by both long investors and short-sellers. Empirically, we find that short-sellers were responsible for a substantial fraction of the liquidity premium for on-the-run Treasuries from November 1995 through July 2009. GIVEN TWO SECURITIES WITH similar cash flows, the more liquid security often trades at a higher price than its less liquid counterpart. This price premium is usually thought to reflect the future benefits that long investors attribute to securities that can be sold quickly and with little price impact (e.g., Amihud and Mendelson (1986)). The more liquid security also frequently costs more to borrow, or trades on special, in financing markets. Previous literature argues that this financing premium is a natural counterpart to the price premium: short-sellers readily pay more to borrow securities that can be sold at a premium (e.g., Duffie (1996), Krishnamurthy (2002)).However, short-sellers themselves may also value a liquid security over and above the higher sale price they receive. When closing out a position, shortsellers are required to deliver the specific security that they initially borrowed and sold short. As such, they naturally prefer to use liquid securities that can be bought back easily. Indeed, short-sellers can pay a net premium for these future liquidity benefits if it costs them more to borrow the liquid security than they expect to recoup from selling it at a higher price. As the following example illustrates, we use this insight to decompose the price premium for a liquid security into the net premiums paid by long investors and short-sellers.EXAMPLE: Suppose that a liquid security trades for $100,000, and an otherwise equivalent but less liquid security costs $99,850. Prices are expected to converge at the end of the period so that the price premium for the liquid security is * Snehal Banerjee is with Northwestern University and Jeremy J.

Short-sellers pay $200 more to borrow it but recoup $150 by selling it at the higher price. As a whole, long investors in the liquid security ...
