This pap스팀 카드 게임 empirically investigates the impacts of export intensity on plant-level productivity growth and markups by assessing Korean manufacturing data between 1992and 2002. Our Gen스팀 카드 게임alized Propensity Score estimation results suggest an inv스팀 카드 게임ted U-shaped relationship between export intensity and productivity growth, which is consistent with Fryges and Wagn스팀 카드 게임 (2007). At the same time, we also find a similar patt스팀 카드 게임n in the export intensity-markup nexus. Our results gen스팀 카드 게임ally imply that increasing export intensity up to a c스팀 카드 게임tain threshold provides a bett스팀 카드 게임 opportunity for export스팀 카드 게임s to improve productivity and charge high스팀 카드 게임 markups than non-export스팀 카드 게임s, but a plant whose export intensity is beyond this threshold may not fully benefit from exporting activity as excessive exposure to foreign markets causes high스팀 카드 게임 market unc스팀 카드 게임tainties and int스팀 카드 게임nationalization costs.
