The shareholders of the companies that buy will lose roughly $300 billion in market value, as markets interpret the acquisition as a signal that managers are exuberant and uncontrolled empire-builders rather than flinty-eyed trustees maximizing payouts to investors. This $300 billion is a tax that shareholders of growing companies think is worth paying (or perhaps cannot find a way to avoid paying) for energetic corporate executives.
相对于其资产在并购前的价值，资产的出售方会获得约8000亿美元的收益。收购方公司的股东则会损失约3000亿美元的市值，那是因为市场将收购理解为这样的信号，即：经理人们都是好大喜功、我行我素的野心家而不是为投资者创造最大化收益的、目光严峻的托管人。这3000亿美元是成长性公司的股东甘愿为精力充沛的公司管理者所支付的税（或者也可能是他们不得不支付的税）。
