Additional information

This dissertation aims to investigate the dynamics of the air transport market in African countries and its relationship with economic development. The study developed air liberalization indices, estimated the concentration level of the market, and analyzed causal relationships between air travel demand and economic development. An assessment of Africa's air transport market amid COVID-19 and a forecast for its temporal recovery are presented. The results of the analyses indicate that there are differences between countries and regional dimensions, which can be used to make context-specific policy suggestions.
