Coffee revenue distributes widely and enters the domestic economy through smallholder incomes. Gold revenue, particularly re-export and refining flow, concentrates in a small number of corporate hands and can leave as quickly as it arrives.
The macro consequence is that headline export strength no longer maps cleanly onto household demand or rural incomes.
This is not a new phenomenon in resource economics; it is the standard pattern behind what economists label the resource curse, where a booming extractive export sector coexists with stagnant broad-based income growth. Uganda's coffee-to-gold transition is a useful live illustration of that mechanism rather than an unprecedented one.
