This study investigates the determinants of growth and competitiveness of Zambia’s flower exports to three main export destinations—the Netherlands, the UK and Germany—using annual time series data from 1990 to 2010. Acknowledging that time series data are often nonstationary, leading to misleading economic analyses, the study employs cointegration and error correction models to establish factors of conditions growth and competitiveness of Zambia’s flower exports. The results show that supply and competitiveness of flower exports are positively influenced by domestic flower production, real GDP and population of importing countries, relative depreciation of domestic currency and world export prices. In contrast, exports from competing countries and real interest rates were found to negatively influence flower exports. This seems to suggest that monetary policies and exchange rate regimes that promote trade are required for enhancing and fostering an environment favorable for flower production and exporting. In addition, the replacement of Zambia’s flower exports by those from other countries dictates that there must be a quality improvement so the country’s exports can compete favorably with those from other countries.
