Although the efficiency of the water sector has been studied extensively utilising data envelopment analysis (DEA), the literature tends to use the conventional DEA model to compute efficiency scores. However, conventional DEA input/output data may contain random errors, which may result in distorted efficiency frontiers due to statistical noise.

The majority of African states continue to be regarded as extractive states. We use the Cape Colony's public expenditure to account for the emergence of extractive states in Africa. With a sub-imperial role for Southern African colonial expansion, the Cape Colony became a template for extractive practices that continue to characterize the region. Using public expenditure data, budget debates and existing historiography, we trace the elite competition for limited public resources that associated the Cape's transition from an agrarian society to a mining-led economy.
