For positive view, liquid assets are less costly to monitor and liquidate for bondholders and so higher asset liquidity
increases the amount of capital firms can borrow, as well as the optimal leverage (Williamson, 1988; Shleifer and
Vishny, 1992).
Also in trade-off theory, when choosing the appropriate
level of debt, investors trade off the expected costs of
default against potential improvements in the operating
policy of a firm. As asset liquidity increases, the costs of
default decrease, and investors are more likely to use
debt to obtain information about the company (Harris and
Raviv, 1992). In this paper, as a proxy for liquidity, we
measure liquidity as current asset minus total cash and
equivalent divided by total assets.
