Globalization, Growth, Inequality and Poverty in Africa: A Macroeconomic Perspective

The last two decades has witnessed an increase in globalizing influences affecting most countries, Africa included. These influences have arisen partly as a result of domestic and international policies, such as trade policies, and partly as a result of general globalizing impulses, such as technological developments and enhanced communications. The single overarching objective of this paper is to outline the macro evidence on the extent to which globalization is taking place and poverty is reducing in Africa, and to consider this to both characteristics of the region (i.e., within the region) and relative to other global regions. It draws on some of the most recent evidence about the globalizing processes in various forms so as to try to determine the speed and extent of globalization in Africa. This helps to put into proper perspective the impact of globalization on poverty and inequality. It is essentially a partial and descriptive approach, at best indicative of associations, and stops short of attempting to identify, empirically, channels of influence and causal relationships.globalization, inequality, poverty, Sub-Saharan Africa

Aid and investment in statistics for Africa

Over many past decades countries in sub-Saharan Africa have received extensive bilateral and multilateral aid in support of the production of relevant, timely, and good quality data and statistics. But assessing aid effectiveness in the statistical area is a complex matter. Many datasets are effectively (global) public goods, as any restrictions on their availability and use are eventually relaxed. Hence it is extremely difficult to value or even measure the eventual impact of data production on general well-being. The aim of this paper is to review and scope how aid effectiveness might be assessed in this area. It sets out the context, the issues, and some possible approaches, going beyond existing measures of statistical capacity-building

Carbon Capture and Storage: Wishful Thinking or a Meaningful Part of the Climate Change Solution

In the lead-up to the climate change negotiations that are scheduled to take place in Copenhagen towards the end of 2009, pursuant to the United Nations Framework Convention on Climate Change, and in order to reach agreement on a post-Kyoto Protocol international climate change regime, many countries around the globe are considering the options available to them to reduce greenhouse gas (GHG) emissions in a manner that will minimize the cost impacts to economies already battered from the onslaught of the 2008 global financial crisis. In addition to confronting a markedly changed geopolitical landscape including the election of a new administration in the United States under the Democrats and President Barack Obama, the ongoing military confrontation between Hamas and the Israelis in Gaza, an outbreak of terrorist attacks in Mumbai, and Iran drawing ever closer to the possible development of nuclear weapons, the international community is facing what is predicted by some to be the most severe and prolonged economic downturn since the 1930s and the Great Depression. The collapse of the banking systems in several countries triggered in part by the sub-prime [*422] mortgage crisis in the United States has inevitably led to a credit crisis around the globe as job layoffs are expected to climb throughout 2009 and into 2010. The impact of these events on the ability of the international community to address the climate change challenges that lie ahead is fraught with uncertainty and the reluctance of the world's major coal producers to abandon or curtail an industry of vital economic importance in terms of both jobs and exports, has elevated carbon capture and storage (CCS) to increasing levels of importance in the consideration of available energy options. It remains to be seen whether the attention and investment dollars presently committed to the development of CCS technologies around the globe is warranted. This paper will endeavor to outline how CCS is currently viewed by Australia and the European Union as part of their respective energy strategies

Double white dwarf mergers and elemental surface abundances in extreme helium and R Coronae Borealis stars

The surface abundances of extreme helium (EHe) and R Coronae Borealis (RCB) stars are discussed in terms of the merger of a carbon-oxygen white dwarf with a helium white dwarf. The model is expressed as a linear mixture of the individual layers of both constituent white dwarfs, taking account of the specific evolution of each star. In developing this recipe from previous versions, particular attention has been given to the inter-shell abundances of the asymptotic giant branch star which evolved to become the carbon-oxygen white dwarf. Thus the surface composition of the merged star is estimated as a function of the initial mass and metallicity of its progenitor. The question of whether additional nucleosynthesis occurs during the white dwarf merger has been examined. The high observed abundances of carbon and oxygen must either originate by dredge-up from the core of the carbon-oxygen white dwarf during a cold merger or be generated directly by alpha-burning during a hot merger. The presence of large quantities of O18 may be consistent with both scenarios, since a significant O18 pocket develops at the carbon/helium boundary in a number of our post-AGB models. The production of fluorine, neon and phosphorus in the AGB intershell produces n overabundance at the surface of the merged stars, but generally not in sufficient quantity. However, the evidence for an AGB origin for these elements points to progenitor stars with initial masses in the range 1.9 - 3 solar masses. There is not yet sufficient information to discriminate the origin (fossil or prompt) of all the abundance anomalies observed in EHe and RCB stars. Further work is required on argon and s-process elements in the AGB intershell, and on the predicted yields of all elements from a hot merger.Comment: 20 pages, 8 figures, 3 tables, MNRAS in pres

Association of drusen deposition with choroidal intercapillary pillars in the aging human eye

PURPOSE. To determine the pattern of drusen accumulation with age and to investigate the initial sites of deposition and their relationship to choroidal capillaries in human donor eyes from the eye bank of Moorfields Eye Hospital.METHODS. Wholemounted, hydrated preparations of the choriocapillaris and Bruch's membrane from donor eyes ranging from 42 to 95 years, with or without retinal pigment epithelium (RPE), were examined by conventional and confocal microscopy. Drusen were visualized by their autofluorescence.RESULTS. In all age groups studied autofluorescent drusen were present at the equator but were not found centrally where the vascular architecture is different, being tubular rather than a honeycomb pattern. Autofluorescing drusen were strongly associated with the lateral walls of the choriocapillaris (an area commonly known as the intercapillary pillars of the choriocapillaris (P = 0.028; Wilcoxon signed ranks test). Nonfluorescing drusen were occasionally seen centrally, but were not easily identified, and because of their large size, their localization with respect to capillary walls was not possible.CONCLUSIONS. These results strongly support the notion that autofluorescent drusen are not randomly distributed and have a specific spatial relationship to choroidal vessel walls. That equatorial drusen fluoresce, whereas central drusen do not, suggests that they may have different chemical compositions at the two sites and possibly different significance in age-related macular disease

Aid effort and its determinants

The paper empirically explores the factors that could have accounted for the generally declining aid effort (defined as the generosity ratio, or the share of GDP given as aid) of bilateral donors over the last three decades. Annual panel data over 1970-2000 period for the 22 DAC members are used in a series of regressions. The findings suggest the existence of progressivity of aid in relation to donor income. There is also evidence of the economies of scale, in the sense that the share of aid in income decreases with growth in the size of donor country population. Domestic pro-poor tendency also appears to enhance donor generosity, and a positive ‘peer pressure’ effect is also observed. In addition, the extent of military adventurism of the donor is observed to have enhanced aid effort, just as also the size of government. But no discernible effect is detected for fiscal balance. On the political front, a greater number of checks and balances in the political system as well as the existence of polarization and fractionalization within the government are found to have enhanced aid effort while fractionalization within the opposition has the opposite effect. On the other hand, no discernible and consistent effect of ideological orientation of government is detected. Finally, the movement in the aid effort over time is found to differ between the G7 and non-G7 donors

Determinants of income inequality and its effects on economic growth: Evidence from African countries

The paper empirically investigates, in the context of African countries, the determinants of income distribution and inequality, the effect of inequality on economic growth, and the channels through which inequality affects growth. Data for 35 countries over different periods in the last four decades were employed. Factors identified as having affected income distribution include the level of economic development attained, regional factors, size of government budget and the amount of it devoted to subsidies and transfers, phase of economic cycle, share of agricultural sector in total labour force, as well as human and land resources endowment. Some evidence that high inequality reduces growth is also found. The channels through which inequality affect growth are found to be through reduction in secondary and tertiary education investment, reduction in political stability, and increase in fertility rate. There is, however, no evidence that it affects private saving and investment or the size of government expenditure and taxation, contrary to what is contended in the theoretical literature
