Determinants of Uganda’s Export Performance: A Gravity Model Analysis by Henry Tumwebaze Karamuriro ,Wilfred Nahamya Karukuza

Abstract

Exports play an important role in Uganda’s economy, influencing the level of economic growth, employment and the Balance of Payments.
Uganda has initiated several trade policy reforms aimed at promoting the export sector. However, Uganda’s share in total world exports is still
very low. Given the central role of exports in the economy, it was important to identify the plausible factors affecting export flows between
Uganda and its trading partners. Thus, this paper examines the factors affecting Uganda’s exports using an augmented gravity model of trade.
The panel dataset used was for the period 1980 to 2012. The results suggest that Uganda’s GDP, importer’s GDP, importer’s GDP per capita, per
capita GDP difference between Uganda and its trading partners, real exchange rate, official common language, and contiguity had a positive and
statistically significant effect on Uganda’s exports. The study further, shows that the formation of COMESA and EAC had a significant positive
effect on Uganda’s exports. On the other hand, Uganda’s GDP per capita and distance between Uganda and its trading partners had a negative
effect on Uganda’s export flows. These results are important for trade policy formulation in order to ensure that Uganda’s export potential is
exploited so as to enhance economic growth.
