Building New Plants or Entering by Acquisition? Estimation of an Entry Model for the U.S. Cement Industry Staff Working Paper 2011-1 Héctor Pérez Saiz In many industries, firms usually have two choices when expanding into new markets: They can either build a new plant (greenfield entry) or they can acquire an existing incumbent.
