This paper examines the growth effects of infrastructure stock and quality in Sub Saharan Africa (SSA). While previous studies established that the poor state of infrastructure in SSA slows economic growth, there is little evidence on infrastructure quality and a robust analysis on the causal links between infrastructure and economic growth.
This paper investigates the causal relationship between electricity supply and economic growth in South Africa using annual data covering the period between 1985 and 2014. This paper used a multivariate framework which included trade openness, electricity price, capital and employment as intermittent variables. The ARDL bound testing was employed to establish the long run relationship between these variables. The Vector Error Correction Model (VECM) was estimated to carry out the test of causality. The results support the existence of co-integration among the variables.
In the light of Africa’s palpable deficit in public infrastructure, we use System GMM to estimate a model of economic growth augmented by an infrastructure variable, for a panel of 45 Sub-Saharan African countries, over the period 2000-2011. We find that it is the spending on infrastructure and increments in the access to infrastructure that influence economic growth and development in Sub-Saharan Africa.
Basic and social infrastructure investment can assist in addressing widespread inequality and divided societies by promoting economic growth and social development. The aim of this study is to determine whether basic and social infrastructures investment differently affect economic growth and social development indicators of urban and rural municipalities. We used a balanced panel dataset containing infrastructure, economic, demographic and social indicators for rural and urban municipalities for the period from 1996 to 2012.
The study empirically establishes the causal relationship between financial innovation and economic growth in SADC. Using an Autoregressive Distributed Lag (ARDL) Model, estimated by Pooled Mean Group and Dynamic Fixed Effects, the study finds that financial innovation has a positive relationship to economic growth in long run for SADC. The long run estimations, however, show existence of a weak relationship. Introducing a direct measure of financial innovation buttresses the role of financial innovation in growth in SADC.
The debate about the influence of financial market development on economic growth has been ongoing for more than a century. Since Schumpeter (1912) wrote about the happenings on Lombard Street, right up to the economists of today, there is growing interest into how financial market development affects economic activity and hence economic growth. With economic growth gaining prominence in respect of development discourse, inquiry into the finance-growth nexus has grown rapidly.
This paper empirically identifies the main driving forces behind the recent development in economic growth across Sub-Saharan Africa based on a two-step procedure. Given the role of convergence in explaining the level of economic development, the first step employs the new extension of the sigma convergence developed by Phillip and Sul (2007) to test and endogenously identify the formation of different steady state paths across a sample of 34 countries selected based on available data over the period 1996-2010.
This paper investigates the incentive for developing adaptation technology in a world with changing climate within the directed technical change framework. Consistent with the market size effect, we show that technological change will tend to be biased in favour of the sector that employs the greater share of the work force over time, when the inputs are sufficiently substitutable.
