Research interests

Roads are important for economic growth and development. They reduce firm transportation costs, stimulate trade and create jobs. Transport infrastructure projects entail large capital investments and governments in Africa are now investing heavily in these projects. Africa lags behind developing countries elsewhere on the quality and quantity of infrastructure and this impedes its economic growth and development. 

There is very little literature on the economic impacts of transport infrastructures on developing countries, especially Africa. My research aims to analyse how reduced transport costs induced by improved highways affects firm-level economic activity in Africa.
