Probably one of the broadest indicators of a nation’s economic strength can be gauged from its gross domestic product (GDP), as this measure is an estimate of the value of goods and services produced by an economy in a given period (Tayeb, 1992). The notion that international trade can influence GDP has been explored by several economic theorists (Marin, 1992; Meier, 1984) and culminated in the export-led growth thesis. The tenet under- lying this volume of research is that as export sales increase, other things being equal, the GDP of a nation will rise and provide a stimu- lus to improved economic well-being and societal prosperity. The way in which this relationship can be interpreted suggests that export performance has a stimulating effect throughout a country’s economy in the form of technological spillovers and other related favourable externalities (Marin, 1992). Export activities may exert these influences because exposure to international markets demands improved efficiency, and supports product and process innovation activities, while increases in specialization encourage prof- itable exploitation of economies of scale (Temple, 1994). Thus, the export-led growth thesis predicts export growth will cause economy-wide productivity gains in the form of enhanced levels of GDP.
