- Summary:
- I assess the efficiency of transport networks for every country in Africa. Using rich spatial data, I simulate trade flows over more than 70,000 links covering the entire continent. I maximise over the space of networks and find the optimal road system for every African state. My simulations predict that Africa would gain 1.1% of total welfare from better organising its national road systems. I then construct a novel dataset of local network inefficiency and I find that colonial infrastructure projects significantly skew trade networks towards a sub-optimal equilibrium. I also find evidence for regional favouritism and inefficient aid provision.
