Manuscript Type Empirical Research Question/Issue While most prior studies on the value of political connections focus on the political connections of controlling shareholders and top management, we examine the performance impact of appointing politically connected outside directors (PCODs) in Korean chaebol firms. Research Findings/Insights Using a manually collected sample of PCODs in Korean chaebol firms, we find that larger, high‐performing, less volatile firms with a larger board and higher divergence between voting rights and cash flow rights are more likely to appoint PCODs in the next year. We also report that firms with a high number of PCODs exhibit better operating performance and enjoy lower risk. On the other hand, we find evidence of weak monitoring ability by PCODs. Overall, we suggest that the number of PCODs correlates positively with firm performance, and that the value effect of PCODs increases with the importance of internal trade among group affiliates, the existence of inside directorship by controlling shareholders, and potential settlements from pending litigation. We further differentiate between PCODs and find that former government officials as PCODs drive our findings. Theoretical/Academic Implications This study contributes to corporate governance knowledge by revealing the relationship between PCODs and firm performance via an empirical inquiry into the role of PCODs on the board. As the controlling shareholders of Korean chaebol firms obtain greater private benefits of control, and such firms may face active government involvement in curbing controlling shareholders’ rent extraction, we examine the role and effects of PCODs in these situations and find evidence of the PCOD's value‐enhancing effect. We also complement and extend prior studies by providing more direct mechanisms through which PCODs can add value above and beyond firms’ ownership structure. Additionally, we expand the concept of political connection by analyzing outside directors’ human and social capital from the resource dependence theory perspective. Our attempt complements prior research's exclusive focus on connections of large shareholders or top executives to political parties and is more comprehensive in illustrating the firm's dynamic business environment. Practitioner/Policy Implications The results of our study are potentially useful to regulators, who will benefit from an understanding of how the presence of PCODs on boards affects firm performance. In particular, our results suggest that in countries where recent reforms aim to improve minority investor protection and market confidence, regulators should consider the composition of outside directors as well as explicit board independence. The results of our study may also be useful to investors, financial analysts, and auditors, as they highlight the importance of considering specific features of board composition when assessing firms’ future operating performance and risk mechanisms.
