Business acquisition, resource redeployment, and asset divestiture are elem
ents of a dynamic process in which firms change their businesses by recombi
ning internal and external resources. Analyzing 253 horizontal acquisitions
, we show that post-acquisition resource redeployment leads to asset divest
iture from the business that receives the redeployed resources, but not fro
m the business that contributes the new resources. Consistent with scale ec
onomies rationales, we find that strategic similarity also leads to greater
asset divestiture from the target firms. Many theoretical perspectives are
skeptical about the positive rationale for acquisitions and many of these
believe that asset divestiture is evidence of acquisition failure. Our argu
ments and analysis help refine the accepted wisdom. In particular, the patt
ern of resource redeployment and asset divestiture in our analysis suggests
that acquisitions provide a means of reconfiguring the structure of resour
ces within firms and that asset divestiture is a logical consequence of thi
s reconfiguration process. Copyright (C) 2001 John Wiley & Sons, Ltd.
