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...

The objective of the study is to examine, identify, and quantify the factors behind Africa's high prices for road transport. Such prices are a major obstacle to economic growth in the region, as shown in several studies. For example, Amjadi and Yeats (1995) concluded that transport costs in...
