(concepts of continuous-time accounting variables)
4.资本成本生成函数(capital cost generating function): Suppose r(t) is function of cumulative capital cost from t0 to t. If for any t [t0 , t1 ] , ( z ) satisfies
2. 影子股利生成函数(Shadow dividend generating function) 影子股利指由于股利支付能力的提高而导致的股票价 格的提高。 Shadow dividend: the increase of stock price caused by the increased ability to pay dividends due to the earnings. 如果时刻 t 形成影子股利 d(z), 则称d(z) 为影子股 利生成函数。 If shadow dividend, d(z), is acquired at time z, then, d(z) is called a shadow dividend function.

is called a capital cost generating function of the firm in the period.

连续时间企业价值评估模型
Continous-time corporate valuation model
一、离散时间企业价值模型的主要缺陷 (Main defects of discrete-time corporate valuation models)
1.收益(自由现金流量,股利)生成与折现时间的不一 致性 The generating time of income(free cash flow, or dividend) is Inconsistent with its discounting time 2.预测的困难(difficult to forecast) 股利(股利政策 dividend police) 自由现金流量(投资investment,长期负债long-term liabilities) 超常收益(linear autoregressive assumption?) 3.折现率的变化(the change of discount rate in the future)

3. 股权账面价值生成函数(Book value generating function) Suppose B(t) is a function of book value about time t. If for any t [t0 , t1 ] , b(z) satisfies
连续干净盈余关系假设(continuoustime clean surplus relation):
