Revisiting the effect of regional integration on African trade: evidence from meta-analysis and gravity model

Two main shortcomings flaw the estimation of gravity model in previous studies that examined the trade-creating effects of African Regional Trade Agreements (RTAs). First, these studies fail to account for the multilateral resistance term. This omission makes the estimates from standard gravity model bias and inconsistent. Second, there is a significant proportion of zero trade flows, however, these studies also fail to account for them properly. They use either the Tobit model or replace zero flows with arbitrary small values. Apart from these problems, they also exhibit considerable heterogeneity in the RTA effects on trade. In this paper, a meta-analysis of previous empirical studies is conducted to derive a combined effect size and also to explain the heterogeneity. In addition, I use the gravity model to compare the trade-creating effect of the main African RTAs. Using the gravity model, I compare the estimation methods of previous studies to the Poisson pseudo-maximum-likelihood estimator that tackles the zero flows. From the meta-analysis, I find a general positive effect of African RTAs of about 27%–32%. A comparative assessment of the RTAs using gravity model shows a striking heterogeneity.     

Explaining banking stability in Sub-Saharan Africa

The study examined banking stability in Sub-Saharan Africa. The results reveal that banking spread (Net Interest Margin – NIM) is the main determinant of stability and the major means to achieve stability during crises periods. We however find the existence of a threshold effect in NIM.Crises in the banking sector consistently showed to reduce stability. While the results show that high percentage of foreign banks reduce stability, we find foreign banks help stabilize the banking sector in periods of crises. The results show that diversification could also have a positive impact on stability (Z-score) even though this relationship was not robust enough. The results also largely support the competition-fragility view. Particularly, we find that less competition during crises periods can help improve stability. Again, we find evidence for both concentration-stability and concentration-fragility hypotheses depending on the stability measure used. We however find that when large banks in concentrated markets are well regulated, stability could be improved. Weak regulatory environment reduces stability (Z-score) directly and matters during crises periods. Our results are robust to the use of different indicators of stability and estimation methods.     

Possibilities and Constraints of Market‐Led Land Reforms in Southern Africa: An Analysis of Transfers of Commercial Farmland in Postcolonial Zimbabwe, 1980–2000

This paper provides a systematic basis, hitherto missing in the current scholarship, to quantify land transfers in Zimbabwe after 1980. It uses title deed information to determine year of sale via a number of sources. The main finding of this research is that a great deal of land changed ownership during this period, which, if the government had been committed to land reform, it could have acted upon. Evidence suggests as much as 67 per cent of white‐owned land changed ownership after 1980. The second is that, while a large amount of land did change hands, it was not the 80 per cent that many white farmers and their supporters have claimed. The figure of 69 per cent is still very high, but it is apparent that much of this did not represent ‘true’ transfer of land. By further investigating the land that did change hands, this paper also raises questions about (a) the possibilities of market‐led land reform in Zimbabwe and Southern Africa, and (b) the relationship between white capital and the new political elite in the postcolonial state.     

Foreign aid and governance in Africa

This paper investigates the effect of foreign aid on governance in order to extend the debate on foreign aid and to verify common positions from Moyo’s ‘Dead Aid’, Collier’s ‘Bottom Billion’ and Eubank’s ‘Somaliland’. The empirical evidence is based on updated data from 52 African countries for the period 1996–2010. An endogeneity robust instrumental variable Two-Stage-Least Squares empirical strategy is employed. The findings reveal that development assistance deteriorates economic (regulation quality and government effectiveness) and institutional (corruption-control and rule of law) governance, but has an insignificant effect on political (political stability, voice and accountability) governance. While, these findings are broadly in accordance with Moyo and Collier on weak governance, they neither confirm the Eubank position on political governance nor the Asongu stance on the aid-corruption nexus in a debate with Okada and Samreth. The use of foreign aid as an instrument to influence the election and replacement of political leaders in Africa may have insignificant results. It is time to solve the second tragedy of foreign aid and that economists and policy makers start rethinking the models and theories on which foreign aid is used to influence economic, institutional and political governance in recipient countries.     

Migrant remittances and fertility

This study examines the role of migrants’ remittances in developing countries’ fertility transition. Employing an unbalanced panel of South Asian countries and controlling for various economic and socio-demographic factors, we find that remittances are significantly associated with a lower number of children born to women of childbearing age. This suggests the remittances’ substitution effect to be at play rather than the income effect, and may result from decreased need for children for financing the household’s future needs as well as from better access to healthcare and contraceptive methods available to migrant households. Remittances’ association with fertility appears to be more important than the transfer of fertility norms from migrants’ host countries. The monetary aspects of international migration may therefore be more important for the region’s demographic transition than social remittances.     

Is Africa integrating? Evidence from product markets

This paper presents a price-based assessment of product market integration in Africa using disaggregated retail prices for 91 products and 12 African cities from 1991 to 2008. We find evidence of substantial deviations from the law of one price ? product price differences between the cities averaged 76% over the period – a result that is consistent with the presence of large barriers to trade in the continent. Mean price differences across cities fell by close to a quarter over the period, but the decline was concentrated in the early 1990s with little progress subsequently, despite the regional trade policies implemented by the countries. Gravity-style estimates reveal that reductions in external tariffs and global trends towards price convergence in the early 1990s are the key contributors to the trend in price integration amongst the African cities.     

Clustering attendees at the Philharmonic Orchestra’s Summer Festival

There has been an increase in the number of arts and music festivals held annually in South Africa. These festivals range from wide all-encompassing arts festivals, such as the National Arts Festival, to specific festivals that cater for very specific audiences, such as the Jazz Festival and the Philharmonic Orchestra Festival. It may therefore be expected that the attendees of the various types of festivals would differ quite substantially. While much research has been conducted to understand visitor behaviour at general arts festivals and the economic contributions of these festivals, attendees of these more specialised events have been neglected. However, understanding who the attendees are and their behaviour is paramount to the sustainability of these festivals. Therefore, this paper aims to address this void and set the following objectives: (1) to compile a profile of attendees at the Philharmonic Orchestra Festival; (2) to cluster attendees of the Festival into distinct groups; and (3) to compare the various clusters with one another. Data were obtained by administrating 500 visitor questionnaires during January 2010. Using cluster analysis, visitors are grouped based on various characteristics and the differences between the clusters are explored using factor analysis and analysis of variance. Main results indicate that most visitors are mature in age and well educated, from which three clusters were identified with differences evident between the clusters.     

Foreign Direct Investment,Institutional Voids,and the Internationalization of Mining Companies into Africa

The paper investigates the factors influencing the internationalization of mining firms into Africa and the strategies employed. We find that the three most important factors identified by mining houses as influencing their decisions to invest are all related to institutional voids particular to developing countries—security of tenure, political stability and poor infrastructure. South African firms have shown themselves to be adept to doing business in volatile political and institutional environments because of their experience within their home base with relatively weaker institutions. They have therefore developed advantages over multinational enterprises from industrialized countries to doing business in these new frontiers.
