报告题目： Investment under Uncertainty with Financial Constraints
报告时间： 2017年12月14日
报告人观点：We develop a theory of investment, seasoned equity offerings (SEOs), and corporate savings under uncertainty for a financially constrained firm, featuring growth and abandonment options and payout policies. Facing costly external financing, the firm prefers to fund its investment internally, so that its optimal policies and value depend on both its earnings fundamentals and liquidity holdings. The firm values not only real flexibility but also financial flexibility. The interaction of real and financial flexibility fundamentally alters the standard real options results: (1) The value of growth and abandonment options effectively vanishes for firms with low internal financing ability; (2) As the firm's savings accumulate, its incentive to forgo costly external financing and rely solely on internal funds for investment increases, which causes it to substantially delay its investment; (3) A financially constrained firm over-invests in early stages of its life-cycle in an effort to quickly build up its cash-flow generating capacity and thereby relax its future financial constraints. Our theory of SEOs captures both firm survival and growth motives, and is broadly consistent with the empirical evidence.
