Revisiting the Bright and Dark Sides of Capital Flows in Business Groups

Prior studies report that the business group structure and the associated intra-group capital flows are prone to conflicts of interest between controlling shareholders and minority investors. Yet business group is a prevalent and stable structure around the globe, particularly where capital markets are underdeveloped. Using data from China, this paper empirically studies the trade-off between the negative and positive roles played by intra-group capital flows and tests the efficiency implications of such trade-off. We find that from the perspective of the whole group, intra-group capital flows are most efficient when the groups are least subject to conflicts of interest between controlling shareholders and minority shareholders and when they face strong external financing constraints.
