Abstract: The environment and security literature has argued that freshwater scarcity often leads to inter-state conflict, and possibly acute violence. The contention, however, ignores the long history of hydro-political cooperation exemplified by hundreds of documented agreements. Building on a theory that considers the relationship between scarcity and hydro-political cooperation, this paper empirically investigates why treaties are negotiated for some rivers and between some riparians, and not others. The paper suggests that long-term water scarcity has a significant influence on levels of cooperation. Additional variables considered include trade, level of governance among the riparian states, and the geography of the river. Findings confirm that cooperation and scarcity embody a concave (inverted U curve) relationship. Governance has a positive impact on cooperation. In addition, riparians may either arrange the use of their scarce water resources via a treaty or trade (and indirectly exchange [virtual] water). Scarcity, governance, and trade were found to be most salient in explaining levels of cooperation while geography is significant in some of the estimates.

Remittances sent by African migrants have become an important source of external finance for countries in the Sub-Saharan African region. In many African countries, these flows are larger than foreign direct investment and portfolio debt and equity flows. In some cases, they are similar in size to official aid from multilateral and bilateral donors. Remittance markets in Africa, however, remain less developed than other regions. The share of informal or unrecorded remittances is among the highest for Sub-Saharan African countries. Remittance costs tend to be significantly higher in Africa both for sending remittances from outside the region and for within-Africa (South-South) remittance corr...
The sizeable increase in income inequality experienced in advanced economies and many parts of the world since the 1990s and the severe consequences of the global economic and financial crisis have brought distributional issues to the top of the policy agenda. The challenge for many governments is to address concerns over rising inequality while simultaneously promoting economic efficiency and more robust economic growth. The book delves into this discussion by analyzing fiscal policy and its link with inequality. Fiscal policy is the government’s most powerful tool for addressing inequality. It affects households ‘consumption directly (through taxes and transfers) and indirectly (via in...
This paper is an excerpt from Inequality and Fiscal Policy. The sizeable increase in income inequality experienced in advanced economies and many parts of the world since the 1990s and the severe consequences of the global economic and financial crisis have brought issues on equity and distribution to the top of the policy agenda. The book delves into this discussion by analyzing fiscal policy and its link with inequality. Fiscal policy is the government’s most powerful tool for addressing inequality. It affects household consumption directly and indirectly. An important message of the book is that growth and equity are not necessarily at odds; with the appropriate mix of policy instruments and careful policy design, countries can in many cases achieve better distributional outcomes and improve economic efficiency. Country case studies demonstrate the diversity of challenges and the diverging ways to use fiscal policy for redistribution. The analysis presented in the book builds on work by IMF economists and leading academics.
This paper studies the fiscal implications for the Beninese economy of scaling up of public investment when the government is subject to inefficiencies on the spending and on the tax collection side. While scaling up of public investments results in higher long-run output and consumption levels, a fiscal stabilization package is required in order to preserve fiscal sustainability. A welfare analysis shows that consumers’ welfare is increased when the government smoothes the fiscal adjustment via higher borrowing. Moreover, the comparison between several stabilization packages highlights the fact that higher welfare is achieved when the government relies mostly on taxation of capital as this allows higher levels of consumption to materialize earlier. Lower fiscal costs can however be achieved if the government manages to reduce inefficiency in tax collection. Finally, we consider a change in the trade regime that causes a decline in revenues. We find that the higher fiscal burden required to preserve fiscal sustainability would completely wipe out the welfare gain of higher public investments.
HIV/AIDS reverses life expectancy gains, erodes productivity, consumes savings and dilutes growth efforts, threatening the realization of the Millennium Development Goals (MDGs) in Africa. The report is the result of an extensive analytical and consultative process begun in 2006, that engaged more than 1,000 people from over 30 countries and many institutions mostly in Africa, as well as UN agencies, multilateral and bilateral donors, and foundations. The report reaffirms the Bank's commitment to combating HIV/AIDS in Africa, moving from its initial emergency response to the next phase, including the goal to provide at least US $250 million annually and to create an Africa HIV/AIDS Incentive Fund to enhance the evidence base, promote the multisectoral response and provide technical support, analysis and policy advice to countries.
The major trends in terms of GDP growth rates, conditions of market forces, and the core inflation crisis in Botswana are analyzed in detail in the report. It has been suggested that although the recovery from the financial crisis of Botswana is the strongest compared with other middle-income countries, the overall results do not point toward a positive development in the economy. The need for authorities to take up certain measures and modify their methods of functioning is pivotal to Botswana's survival in the existing fragile economic environment.
This volume analyzes the cost of HIV/AIDS from a fiscal perspective in Botswana, South Africa, Uganda, and Swaziland.
