Abstract:

In this paper, we investigate the effect of suppliers' political risk on their customer concentration. Using firm-level political measures, we find that suppliers' political risk will lead to a more diversified customer pool and a lower customer concentration. We address challenges to a causal interpretation of these findings by utilizing exogenous increases in political firms that are affected by redrawing of electoral district boundaries after the decennial census of 2010 and by using the political polarization index as an instrumental variable. This effect is more pronounced for firms with fewer lobby activities. Moreover, the political risk related to trade has the most important impact on customer concentration. Facing heighten political risk, suppliers tend to switch to local customer. Further analysis suggests that the reduced customer concentration is more likely driven by suppliers instead of customers. Overall, our empirical evidence indicates that political risk significantly affects corporate diversification strategy.
