Many assets derive their value not only from future cash flows but also from their ability to serve as collateral. In this paper, we investigate this collateral value and its impact on asset returns in an infinite-horizon general equilibrium model with heterogeneous agents facing collateral constraints for borrowing. We document that borrowing against collateral substantially increases the return volatility of long-lived assets. Moreover, otherwise identical assets with different degrees of collateralizability exhibit substantially different return dynamics because their prices contain a sizable collateral premium that varies over time. This premium can be positive even for assets that never pay dividends.
Assets with collateral properties are in fashion these days, for understandable reasons. Yet, the pricing of these assets has not been much studied. This paper fills this void starting, of course, from a Lucas tree with interesting results for the moments of excess returns.
