This paper asks how market expansion contributes to productivity growth. It investigates whether entry to both new international markets and new domestic markets is associated with greater productivity growth. It also examines whether exit from export markets is necessarily associated with deteriorating performance or whether it too can lead to success if associated with movements to new markets. Finally, the paper drills down into the strategic stance of firms that move to new markets to examine the strategic differences that set them apart from their compatriots that do not find themselves able to adapt.
