This study examines how exchange rate volatility can influence total factor productivity (TFP) in various dimensions. Using Korean manufacturing plant-level data for 1990-2007, we first compare and contrast the effects of exchange rate volatility on TFPs between two different exchange rate re-gimes―pegged and free floating. We find that the exchange rate volatility had a negative effect on productivity in both regimes but this negative ef-fect was greater during the period when exchange rate fluctuation was re-stricted, compared to the period with free floating rate. We also find that the negative effects of the volatility on productivity were heterogeneous over TFP quantiles and exhibited an inverted W-shape curve. In particular, the negative effects were more pronounced for exporting plants that had the lowest or highest TFPs.
