根据球和布朗(1968),企业的收入在美国时间会一起行动。它已经证明了大约一半的水平的变化的平均每股收益(EPS)公司可能是受整个经济环境的影响。至少部分的改变公司的收入从一年到下一个可以预期的。在过去的几年中,如果一个公司的收入与其他公司在一个特定的方式,然后理解这种关系的过去,一起了解其他公司的收入,目前有一个特定的预期回报率。因此,除了确认新的信息可以有类似的影响相当于收入和实际之间的差异变化的预期收入。但并不是所有的这些差异必须新信息。大量的收入变化是由于融资和其他政策决策的公司。球和布朗认为,第一近似,这些变化反映在平均收入的变化。因为能感受到变化的两个组件的影响同时,也就是说,经济宽,政策效果,必须联合估计的关系。
英国媒体学代写essay:企业的收入
According to Ball and Brown (1968), the income of enterprises in America tends to move together over the time. It has been demonstrated that about half of change in the level of average earnings per share (EPS) of a firm could be influenced by the whole economic environment. At least part of the change in the company’s income from one year to the next could be expected. In the past years, if a company’s revenue had been associated with other companies in a particular way, then understanding that relationship of the past, together with the understanding of the income of those other companies, had a particular expected rate of return at present.Therefore, in addition to confirm the impact of new information can have a similar equivalent to the differences between real change in income and expectations of income. But not all of these differences must be new information. A number of changes in income were due to financing and other policy decisions made by the firm. Ball and Brown assumed that, to a first approximation, these changes were reflected in average change in income through time. Since the influence of the two components of change were felt at the same time, that is, economy wide and policy effects, the relationship must be estimated jointly.
