External Financing and Liquidity
解释企业市值与融资活动负相关的原因，认为企业为维持流动性而在预期低收益时融资，导致融资与市值反向变动。
ABSTRACT We explain the observed negative relation between market value of firms and their fund raising activities. Ours is not a signalling model. The firm's objective is to maximize the present value of its income. Considerations of cash availability (liquidity) and unfolding of uncertainty drive our model. Income from operations is an important source of liquidity. Low earnings are associated with low liquidity. Whether earnings are low or not is known to some extent in advance of the realization itself. External financing is pursued in anticipation of the earnings' realization in order to maintain a desired level of liquidity. Therefore, anticipated low earnings are associated with a high level of external financing. Of course, an anticipation of low earnings is also accompanied by a decrease in the firm's value. The empiricist who looks at time series of a firm's value and of its dividend/external financing announcements would then record positive correlation between value and cash distributions and negative correlation between value and external financing.
