Abstract: | Based on 173 acquisitions in the U.S. manufacturing industry, this study examines the impact of organizational differences between acquiring and acquired firms on post-acquisition performance. The findings indicate that differences in top management styles have a negative impact on performance in acquisitions characterized by both high and low levels of post-acquisition integration. However, no such relationship was observed between differences in the reward and evaluation systems and post-acquisition performance in either the high or low integration subgroups. Implications of the findings, along with directions for future research, have been discussed in the concluding section of this paper. |
