Multilateral development banks (MDBs) are one of the most popular forms of international organization, with at least 27 operating in the world today. Although most academics and policy makers focus on the World Bank and major regional MDBs, the majority of MDBs are in fact relatively small, and controlled by developing as opposed to industrialized countries. How do the differing governance arrangements of these ‘minilateral’ development banks (MnDBs) impact their operations? This article takes the Trade and Development Bank (TDB), an MDB in Africa with 22 regional member countries, as a case study to consider this question. Based on an analysis of TDB's track record since 2005 and interviews with management and shareholders, the author finds that borrower‐led governance leads to substantial disadvantages in terms of access to finance. Borrower‐led governance permits TDB and other MnDBs greater operational flexibility, which partially compensates for this financial disadvantage, but these operational strategies come with trade‐offs in terms of developmental effectiveness. The findings suggest that MnDBs have substantial latent potential and, in an increasingly multipolar world, they are likely to grow in coming years. However, MnDBs need to ensure that their developmental value added is strengthened in step with their financial power.  相似文献

An extensive literature on the transformation of food retailingin developing countries by the expansion of supermarkets hashighlighted the implications of the concentration of food valuechains for the continued incorporation of small farmers in freshproduce supply. A critical examination of this literature showsthat extent of the transformation of retailing, and also offood production as a consequence of it, is overestimated, particularlyfor fresh produce. The future landscape of food retailing willbe more varied than the supermarket revolution hypothesis predicts.  相似文献

New work at Kehf el Hammar Cave provides the first well-dated palaeoenvironmental sequence for the Late Upper Palaeolithic in this region of the northwest Maghreb. The archaeological layers are dated via a combination of AMS radiocarbon and luminescence dating methods. The sequence contains charcoal-rich occupation layers with faunal, human and lithic finds. Local vegetational patterns are reconstructed on the basis of preliminary analysis of the charcoal evidence. Using standard calibration curves the AMS radiocarbon dates are compared with proxy evidence for climatic change from sea core records in the Alborán Sea. These appear to show that the Late Upper Palaeolithic occupation of the region coincides closely with Heinrich Event 1, a period marked by intense aridification and dating to ca. 16,700–17,250 calendar years ago.Les nouvelles recherches dans la grotte de Kehf el Hammar ont permis d’obtenir la première séquence paléoenevironnementale bien datée du Paléolithique supérieur tardif au Nord Ouest du Maghreb. En effet, les niveaux archéologiques ont été datés par le radiocarbone par accélérateur (AMS) et des méthodes radiométriques basées sur la luminescence. En revanche, les paléoenvironnements végétaux ont été partiellement reconstitués à base des premières analyses des charbons de bois. Les dates AMS calibrées ont été comparées aux données climatiques issues des carottes marines dans la mer Alborán. Ainsi, les occupations humaines du Paléolithique supérieur tardif dans la région ont sensiblement coïncidé avec l’événement climatique Heinrich 1. Celui-ci correspond à une période qui a été marquée par une aridification intense entre 16.700 et 17.250 ans (cal.).  相似文献
