Increased globalisation of trade has led a growing number of firms to search beyond their traditional domestic markets. As a result, export-led growth has gained focus, particularly amongst industrialising nations, or so-called efficiencydriven economies, in search of economic growth. Policy prescriptions have generally proposed a weakening of the exchange rate as a means to stimulate exports; whilst an exchange rate appreciation would be detrimental to exports and encourage imports. Past research on this topic has been mixed.This research examines the impact of exchange rate on export performance in a sample of nine efficiency-driven economies for the period from 1990 to 2009. These economies, with floating exchange rate arrangements, include Brazil, the Dominican Republic, Malaysia, Mauritius, Mexico, Peru, South Africa, Thailand and Turkey. Panel data models using a fixed-effects method have been applied in this research. The research finds that a weakening of the exchange rate does not necessarily improve export performance. To the contrary, export growth is associated with a stronger, relative exchange rate. The lag effect of exchange rate movement on export performance is slightly more pronounced, but remains statistically insignificant.
