Ownership and operating performance in an emerging market: evidence from Thai IPO firms

We examine the operating performance of Thai firms after they go public. Overall, we find that their performance declines. We then explore the relationship between managerial ownership and the change in firm performance. We find that firms with 'low' and 'high' levels of managerial ownership experience positive relationships between managerial ownership and the change in performance (alignment-of-interest hypothesis), while firms with 'intermediate' levels of managerial ownership exhibit a negative relationship between managerial ownership and the change in performance (entrenchment hypothesis). Examining the operating performance of IPO firms from an emerging market and finding a curvilinear relationship between managerial ownership and the post-IPO change in performance represents two significant contributions to the IPO literature.
