Root Causes of African Underdevelopment

Abstract

What is the root cause of Africa’s current state of under-development? Is it the long history of slave trade, or the legacy of extractive colonial institutions, or the fallout of malaria? A precise answer still eludes us. This paper investigates the relative contribution of these historical factors using an instrumental variable approach. The results show that malaria matters the most and all other factors are statistically insignificant. The mechanism through which malaria impacts economic performance is demonstrated by a strong negative relationship between malaria and national savings and a two period overlapping generation model. The model shows that high malaria incidence adversely affects growth by increasing both mortality and morbidity. Increased mortality from malaria induces households to increase current consumption and save less for the future. Increased morbidity on the other hand adversely affects labour productivity. The combined impact of these two effects is a slowdown of capital accumulation and economic growth.Malaria; Colonial Institutions; Slave Trade; Economic Development
