We test the Shleifer-Vishny hypothesis that asset liquidation values influence both firm leverage and the choice of debt maturity. Using panel data on REITs, we estimate a simultaneous equation model and find that firms specializing in the most (least) liquid assets use more (less) leverage and longer (shorter) maturities. The evidence also suggests that, for REITs, debt maturity and leverage are substitutes, consistent with the theory and predictions of Barclay, Marx and Smith.
