Winner-Picking or Cross-Subsidization? The Strategic Impact of Resource Flexibility in Business Groups

We show that in business groups with efficient internal capital markets both winner-picking and cross-subsidization may occur. Depending on the amount of internal resources, a group may either exit a market in response to increased competition, or rather channel funds to the subsidiary operating in that market. This has important implications for the strategic impact of group membership. Affiliation to a monopolistic subsidiary can make a cash-rich stand-alone firm more vulnerable to entry deterrence. Conversely, a cash-poor firm becomes less sensitive to its financial constraints upon affiliation to a group, and thus less vulnerable to entry deterrence. Finally, resource flexibility within a group makes subsidiaries' reaction functions flatter, thus discouraging rivals' strategic commitments when entry is accommodated.
