The purpose of this paper is to re-examine the acquisition versus greenfield versus exporting question under fixed versus free entry assumptions for local firms. Our finding is that greenfield entry and exporting options are more attractive relative to acquisition when the local market structure adjusts to foreign entry through local entry or exit than when it is fixed. The entering foreign firm may do better or worse under free entry versus a fixed market structure depending on its optimal choice under the latter assumption. ER -
