Working Paper
pdf
– LEAP model application
This study develops a scenario-based model to assess the current and future trends in energy demand in Africa and associated greenhouse gas emissions. Future energy demand is forecast on the basis of socio-economic variables such as gross domestic product, income per capita, population, and...
Working Paper
pdf
This paper develops a scenario-based model to identify and provide an array of electricity demand in Africa, and to derive them from the African power system of development. A system-based approach is performed by applying the scenario methodology developed by Schwartz in the context of the energy...
Working Paper
pdf
High levels of inflexible bilateral trade in southern Africa have limited the participation in the competitive short-term markets, leading to inefficient use of energy infrastructure and blocking the Southern African Power Pool’s long-term goal of transitioning from a cooperative to competitive...

– Proposed model for regional power sector integration in Africa
Regional power pools present a significant and potentially defining opportunity for African power systems to develop domestic energy resources, improve system reliability, and contribute to overall economic development. Hydropower is expected to play a significant role in many regional power pools...
Working Paper
pdf
As the technology of climate-dependent energy sources is improving—both cheaper and more efficient—the energy sources are becoming more accessible for many of the nations in Africa. However, little is known about the underlying climate that would therefore be harvested by renewable technologies...

– Preliminary study of the Inga 3 Dam
Large hydropower dams are at the centre of a debate weighing the value and costs of renewable energy against the risks of climate change. The debate is especially relevant on the African continent, which offers vast hydropower potential, but which is exposed to possible climatic changes. This paper...

pdf
– A hybrid assessment
Projections of regional changes in surface air temperature and precipitation for the greater Nile River basin and northern Africa are presented. The probabilistic projections are obtained through a technique that combines projections of the MIT Integrated Global System Model with climate-change...

– Case Study: Zambezi Basin and South Africa
The present study develops a reliability assessment method of wind resource using optimum reservoir target power operations that maximizes the firm generation of integrated wind and hydro power. A combined water resources model for a system of reservoirs that implements a priority based linear...

– Evaluating Carbon Taxes and Electricity Import Restrictions
We link a bottom-up energy sector model to a recursive dynamic computable general equilibrium model of South Africa in order to examine two of the country’s main energy policy considerations: (i) the introduction of a carbon tax and (ii) liberalization of import supply restrictions in order to...

– Policy Lessons from Recent Experience
This paper investigates the macroeconomic challenges created by a surge in aid inflows. It develops an analytical framework for examining possible policy responses to increased aid, in terms of absorption and spending of aid—where the central bank controls absorption through monetary policy and the...

– When Aid Volatility Matters and When It Does Not
In previous papers we have argued that aid is likely to mitigate the negative effects of external shocks on economic growth (i.e., aid is more effective in countries that are more vulnerable to external shocks). Recently an important debate has emerged about the possible negative effects of aid...
Working Paper
pdf
We examine the properties of alternative monetary policy rules in response to large aid surges in low-income countries characterized by incomplete capital market integration and currency substitution. Using a dynamic stochastic general equilibrium model, we show that simple monetary rules that...

– Looking at the Aid-Social Capital-Growth Nexus
We examine the impact of institutional quality and social capital on aid effectiveness. We find strong evidence that social capital and institutions enhance aid effectiveness. Moreover, once we account for the role of social capital and institutions, the impact of policies tend to disappear. These...
Working Paper
pdf
This paper analyses three issues in strategic donor-recipient interaction motivated by the complexity of the rationale underlying aid. The first is when we have several principals with conflicting objectives. Any one principal cannot offer high powered incentives to the agent to carry out their...
Working Paper
pdf
This paper investigates the role of aid in mitigating the adverse effects of commodity export price shocks on growth in commodity-dependent countries. Using a large cross-country dataset, we find that negative shocks matter for short-term growth, while the ex ante risk of shocks does not seem to...

– An Intertemporal Analysis
This paper examines the welfare implications of foreign aid within the framework of a two-period, two-country model of international trade. It is up to the donor country to decide what fraction of any given aid package is to be made available for the recipient’s immediate, period-one consumption...
