Taxes, Regulations, and the Value of U.S. and U.K. Corporations
用增长理论量化分析1960-2001年美国公司股权价值相对GDP的大幅波动，发现税收和监管体系变化是关键因素，该理论也解释了英国同期更大幅度的波动。
We derive the quantitative implications of growth theory for U.S. corporate equity plus net debt over the period 1960-2001. There were large secular movements in corporate equity values relative to GDP, with dramatic declines in the 1970's and dramatic increases starting in the 1980's and continuing throughout the 1990's. During the same period, there was little change in the capital—output ratio or earnings share of output. We ask specifically whether the theory accounts for these observations. We find that it does, with the critical factor being changes in the U.S. tax and regulatory system. We find that the theory also accounts for the even larger movements in U.K. equity values relative to GDP in this period. Copyright 2005, Wiley-Blackwell.
