21、vidends Versus Investment and Growth红利与投资及增长根据固定红利增长率模型，股价随着当前红利水平Div1和期望增长率g的增加而增加。要使股票的价格最大化，公司要把两个变量都提高。那么就需要权衡：提高增长率可能需要加大投资，而用于投资的资金就不能用于支付红利。通过固定红利增长率模型来深入的研究下这个问题。什么决定了公司的红利增长率？A Simple Model of Growth 一个简单的增长模型Dividend Payout Ratio 红利支付率The fraction of earnings paid as dividends each year定义红

32、 the growth rate is not constant.如果增长率不固定，那么就不能用固定红利增长率模型For example, young firms often have very high initial earnings growth rates. During this period of high growth, these firms often retain 100% of their earnings to exploit profitable investment opportunities. As they mature, their growth slows.

33、 At some point, their earnings exceed their investment needs and they begin to pay dividends.例如，成功的初创公司通常具有很高的初创收益增长率。在高增长期，公司通常保留100%的收益开发有利可图的投资机会。当公司进入成熟期，增长率放缓。在此阶段，收益超过公司的投资需要，于是公司就开始支付红利33Copyright 2007 Pearson Addison-Wesley.

37、(contd)37Copyright 2007 Pearson Addison-Wesley. All rights reserved.Limitations of the Dividend-Discount Model红利折现模型的局限性There is a tremendous amount of uncertainty associated with forecasting a firms dividend growth rate and future dividends.（红利折现模型基于未来支付给股东的红利估计股票的价值）未来红利的预测具有很大的不确定性。Small changes

38、in the assumed dividend growth rate can lead to large changes in the estimated stock price.假设红利增长率微小的改变，都可能导致估计的股价大幅度变动，且难以知道估计的股利增长率哪一个更合理。总之，预测红利需要预测公司的收益、红利支付率和未来股票数量，但收益和利息支出有关，股数和红利支付率取决于公司是否用部分收益回购股票。而借款和回购决策是管理层自行决定的，要预测它显然有很多认为主管因素存在，比预测项目现金流更困难。38Copyright 2007 Pearson Addison-Wesley.
