Competition and efficiency among Vietnam's commercial banks

This article investigates the impact of bank competition on cost and profit efficiency in the Vietnam’s commercial banking system dur-ing 2005–2014. Based on different testing techniques, our results agree with the findings of Turk-Ariss (2010) that bank competition has a negative effect on profit efficiency and those of Pruteanu-Podpiera et al. (2008) and Maudos and de Guevara (2007) that bank competition is negatively related to cost efficiency. We also find that inflation and lag of competition are the two factors affect-ing the competition among these banks.
