In an economy characterized by rapid change, continuous innovation and high intensity and dynamism of competition, the analysis of strategy and competitive advantage has shifted from the more aggregate competitive forces to the idea that firms are essentially different and compete on the basis...

Divestitures have the potential to create shareholder value. However, the magnitude of the wealth effect depends on the likelihood of finding more valuable uses for the divested assets and the seller's ability to eliminate negative synergies. Strong performers should have less scope to benefit...

The decentralization of organizational decision authority has been shown to be complementary to Information Technology (IT) in prior research. We draw from the information processing view of organizations, the IT and de/centralization debate, and organizational learning theory to argue that IT...
