Book Description
"Empirical explorations of the growth and productivity impacts of infrastructure have been characterized by ambiguous (countervailing signs) results with little robustness. A number of explanations of the contradictory findings have been proposed. These range from the crowd-out of private by public sector investment, non-linearities generating the possibility of infrastructure overprovision, simultaneity between infrastructure provision and growth, and the possibility of multiple (hence indirect) channels of influence between infrastructure and productivity improvements. The authors explore these possibilities using panel data for South Africa over the 1970-2000 period, and a range of 19 infrastructure measures. Using a number of alternative measures of productivity, the prevalence of ambiguous (countervailing signs) results, with little systematic pattern is also shown to hold for their data set in estimations that include the infrastructure measures in simple growth frameworks. The authors demonstrate that controlling for potential endogeneity of infrastructure in estimation robustly eliminates virtually all evidence of ambiguous impacts of infrastructure, due for example to possible overinvestment in infrastructure. Controlling for the possibility of endogeneity in the infrastructure measures renders the impact of infrastructure capital not only positive, but of economically meaningful magnitudes. These findings are invariant between the direct impact of infrastructure on labor productivity, and the indirect impact of infrastructure on total factor productivity."--World Bank web site.

Book Description
This book presents a comprehensive account and analysis of the current state of infrastructure in Africa with an unprecedented level of detail. Covering nearly twenty specific topical issues for the ongoing development of African infrastructure--including the economic and political aspects of infrastructure development, financing and the mobilization of domestic resources, and the potential for social inclusion--the volume explicitly challenges current policy, practice, and thinking in this area.

Book Description
Good infrastructure is essential for socio-economic growth and sustainable development. Safe and accessible water supplies, reliable energy, good transport networks and communications technology are all vital to a region’s development agenda. This book presents a comprehensive exploration of the state of infrastructure in Africa and provides an integrated analysis of the challenges the sector faces, based on extensive fieldwork across the continent. Contributors with a wide range of expertise challenge current policy, practice and thinking on issues including the politics of infrastructure development, social inclusion, domestic resource mobilisation and infrastructure financing. The book will be an important resource for academic researchers, students and early career development professionals as well as policymakers and NGOs engaged in dialoguing the infrastructure development options for Africa.

Book Description
The paper investigates empirically the determinants of economic growth for a large sample of sub-Saharan African countries during 1981-92. The results indicate that (i) an increase in private investment has a relatively large positive impact on per capita growth; (ii) growth is stimulated by public policies that lower the budget deficit in relation to GDP (without reducing government investment), reduce the rate of inflation, maintain external competitiveness, promote structural reforms, encourage human capital development, and slow population growth; and (iii) convergence of per capita income occurs after controlling for human capital development and public policies.

Book Description
Sustainable infrastructure development is vital for Africa s prosperity. And now is the time to begin the transformation. This volume is the culmination of an unprecedented effort to document, analyze, and interpret the full extent of the challenge in developing Sub-Saharan Africa s infrastructure sectors. As a result, it represents the most comprehensive reference currently available on infrastructure in the region. The book covers the five main economic infrastructure sectors information and communication technology, irrigation, power, transport, and water and sanitation. 'Africa s Infrastructure: A Time for Transformation' reflects the collaboration of a wide array of African regional institutions and development partners under the auspices of the Infrastructure Consortium for Africa. It presents the findings of the Africa Infrastructure Country Diagnostic (AICD), a project launched following a commitment in 2005 by the international community (after the G8 summit at Gleneagles, Scotland) to scale up financial support for infrastructure development in Africa. The lack of reliable information in this area made it difficult to evaluate the success of past interventions, prioritize current allocations, and provide benchmarks for measuring future progress, hence the need for the AICD. Africa s infrastructure sectors lag well behind those of the rest of the world, and the gap is widening. Some of the main policy-relevant findings highlighted in the book include the following: infrastructure in the region is exceptionally expensive, with tariffs being many times higher than those found elsewhere. Inadequate and expensive infrastructure is retarding growth by 2 percentage points each year. Solving the problem will cost over US$90 billion per year, which is more than twice what is being spent in Africa today. However, money alone is not the answer. Prudent policies, wise management, and sound maintenance can improve efficiency, thereby stretching the infrastructure dollar. There is the potential to recover an additional US$17 billion a year from within the existing infrastructure resource envelope simply by improving efficiency. For example, improved revenue collection and utility management could generate US$3.3 billion per year. Regional power trade could reduce annual costs by US$2 billion. And deregulating the trucking industry could reduce freight costs by one-half. So, raising more funds without also tackling inefficiencies would be like pouring water into a leaking bucket. Finally, the power sector and fragile states represent particular challenges. Even if every efficiency in every infrastructure sector could be captured, a substantial funding gap of $31 billion a year would remain. Nevertheless, the African people and economies cannot wait any longer. Now is the time to begin the transformation to sustainable development.

Book Description
Africa's Power Infrastructure: Investment, Integration, Efficiency is based on the most extensive data collection exercise ever undertaken on infrastructure in Africa: the Africa Country Infrastructure Country Diagnostic (AICD). Data from this study have provided new insights on the extent of a power crisis in the region, characterized by insufficient capacity, low electricity connection rates, high costs, and poor reliabilityùand on what can be done about it. The continent faces an annual power sector financing gap of about $21 billion, with much of the existing spending channeled to maintain and operate high-cost power systems, leaving little for the huge investments needed to provide a long-term solution. Meanwhile, the power crisis is taking a heavy toll on economic growth and productivity. This book asserts that the current impediments to economic growth and development need to be tackled through policies and investment strategies that renew efforts to reform state-owned utilities, build on the lessons of private participation in infrastructure projects, retarget electrification strategies, expand regional power trade, and mobilize new funding resources. Further development of regional power trade would allow Africa to harness larger-scale and more cost-effective energy sources, reducing energy system costs by US$2 billion and carbon dioxide emissions by 70 million tons annually. But reaping the promise of regional trade depends on a handful of major exporting countries raising the large volumes of finance needed to develop generation capacity for export; it also requires a large number of importing countries to muster the requisite political will. With increased utility efficiency and regional power trade in play, power costs would fall and full cost recovery tariffs could become affordable in much of Africa. This will make utilities more creditworthy and help sustain the flow of external finance to the sector, which is essential to close the huge financing gap.
