I develop a model of firm-to-firm search and matching to show that the impact of falling trade costs on firm sourcing decisions and consumer welfare depends on the relative size of search externalities in domestic and international markets. These externalities can be positive if firms share information about potential matches, or negative if the market is congested. Using unique firm-to-firm transaction-level data from Uganda, I document empirical evidence consistent with positive externalities in international markets and negative externalities in domestic markets. I then build a dynamic quantitative version of the model and show that, in Uganda, a 25% reduction in trade costs led to a 3.7% increase in consumer welfare, 12% of which was due to search externalities.
This 2015 Article IV Consultation highlights that Uganda’s recent economic performance has been favorable. Real GDP growth is projected at 5.24 percent for FY2014/15 supported by a fiscal stimulus and a recovery in private consumption. Annual core inflation increased to 4.75 percent in May, from very depressed levels, mainly fueled by the shilling depreciation pass-through. The current account deficit is set to widen to about 9 percent of GDP reflecting increasing capital goods imports, but international reserves remain adequate. The outlook is promising. Growth is estimated at 5.75 percent in FY2015/16 and an average 6.25 percent over the medium-term.
