我使用1994年到2012年的數據,根據市場價值以及公司的債務和股權貝塔值,估計舉債的淨好處。當企業舉債比率較低時,淨效益會隨著舉債增加而增加,但是如果舉債比率太高,淨效益又會隨著舉債增加而減少,這意味著公司存在一個最佳的資本結構。
I estimate the market’s valuation of the net benefits to leverage using panel data from 1994 to 2012, identified from market values and betas of a company’s debt and equity. Net benefits are increasing in leverage for low-debt firms but decrease as leverage becomes very high, implying the existence of an optimal capital structure.
