The strategic impact of resource flexibility in business groups

We show that in business groups with efficient internal capital markets, resources may be channelled to either more or less profitable units. Depending on the amount of internal resources, a group may 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.
