| Zusammenfassung: | Recent research suggests that isolation from regional and international markets has contributed significantly to poverty in many Sub-Saharan African countries. Numerous empirical studies identify poor transport infrastructure and border restrictions as significant deterrents to trade expansion. In response, the African Development Bank has proposed an integrated network of functional roads for the subcontinent. Drawing on new econometric results, the authors quantify the trade-expansion potential and costs of such a network. They use spatial network analysis techniques to identify a network of primary roads connecting all Sub-Saharan capitals and other cities with populations over 500,000. The authors estimate current overland trade flows in the network using econometrically-estimated gravity model parameters, road transport quality indicators, actual road distances, and estimates of economic scale for cities in the network. Then they simulate the effect of feasible continental upgrading by setting network transport quality at a level that is functional, but less highly developed than existing roads in countries like South Africa and Botswana. The authors assess the costs of upgrading with econometric evidence from a large World Bank database of road project costs in Africa. Using a standard approach to forecast error estimation, they derive a range of potential benefits and costs. Their baseline results indicate that continental network upgrading would expand overland trade by about |
