Abstract: This paper studies political connections from the view of the social networks. We build social networks annually from 2009 to 2017, where firm leaders serve or served in the same government institutions are linked together. Empirically, the social network each year shares a similar structure and shows a small-world effect. Furthermore, we apply four network topologies, namely, degree centrality, betweenness centrality, closeness centrality, and the clustering coefficient, to measure the strength of political connections and utilize these new proxies to predict the post performance of initial public offerings (IPOs). We observe political network centrality has negative effects on the short-term and long-term post-IPO stock returns in that the leaders’ position on the political hierarchy is inversely related to the post-performance of IPO firms. This finding may be attributable to the argument of “grabbing hand” that the capability of an IPO firm on acquiring resources or information on the political network is positively correlated to the extent that government officials using their power to reap the private or political benefits instead of firm value maximization.
