In this paper we first investigate if U.S. corporations’ demand for liquidity is influenced by (i) the degree of uncertainty faced by a firm, and (ii) the quality of corporate governance.

    As uncertainty within which a firm operates increases, entrenched managers are better positioned to use the resources of the firm for their personal interests. In those times, it is more difficult for investors to monitor their actions or estimate the true value of their investment decisions.
