我们使用行业商品流信息来衡量1962年至1996年完成的合并中的纵向关系。近三分之一的合并显示出纵向关联。纵向合并活动在1980年代和1990年代较为密集,而在1960年代和1970年代则较少。纵向合并产生的正财富效应明显大于多元化合并;纵向合并的财富效应与纯横向合并的财富效应相当。
We use industry commodity flows information to measure vertical relations in completed mergers from 1962 to 1996. Almost one-third of the mergers display vertical relatedness. Vertical merger activity is more intensive in the 1980s and 1990s and less so in the 1960s and the 1970s. Vertical mergers generate positive wealth effects that are significantly larger than those for diversifying mergers; the wealth effects in vertical mergers are comparable to those in pure horizontal mergers.
