    The Impact of Aid on Growth an aid disaggregation approach

    This paper investigates the impact of aid on growth. A clear departure from the vast majority of the existing literature is that we a disaggregate aid by functional classification. Using the GMM SYS approach to dynamic panel estimator we test the three main competing specifications in the aid and growth literature for a sample of aid recipient countries over the 1974-2001 period. Our results clearly show that the different categories of aid exert different effects on growth. Indeed, we find that project aid exerts a positive and significant impact on growth whilst financial programme aid generally impacts on growth negatively. Our results also show that the impact of non-financial aid, technical assistance grants and food aid, is statistically insignificant. We found, however, no evidence to suggest that policy enhances the growth effect of the aid categories. Our non-linearity tests suggest that only project aid is associated with diminishing returns. Finally, our results confirm the finding that climate related conditions affect the working of aid (project). --Aid,Growth,Dynamic Panel Methods

    The Impact of Climatic Change on Agricultural Production: Is it different for Africa?

    This paper examines the impact of climatic change on the level of total agricultural production of Sub-Sahara Africa (SSA) and non-Sub-Sahara Africa (NSSA) developing countries. In doing so it uses a new cross-country panel climatic dataset in an agricultural production framework. The results show that climate, measured as changes in country-wide rainfall and temperature, has been a major determinant of agricultural production in SSA. In contrast, NSSA countries appear not to be affected by climate in the same manner. Simulations using the estimates suggest that the detrimental changes in climate since the 1960s can account for a substantial portion of the gap in agricultural production between SSA and the rest of the developing world.Climate change, Africa, Agriculture

    Moral Hazard and the Composition of Transfers: Theory with an Application to Foreign Aid

    Get PDF
    The paper presents a theoretical and empirical analysis of a donor’s choice of the composition of unrestricted and in-kind/restricted transfers to a recipient and how this composition is adjusted in response to changes in the moral hazard behavior of the recipient. In-kind or restricted transfers may be used, among others, to control a recipient’s moral hazard behavior but may be associated with deadweight losses. Within the context of foreign aid, we use a canonical political agency model to construct a simple signaling game between a possibly corrupt politician in a recipient country and a donor to illustrate the donor’s optimal choice of tied (restricted) and untied foreign aid. We clarify the condition under which a reduction in the recipient’s moral hazard behavior (i.e., improvement in the level of governance) leads to a fall in the proportion of tied aid. We test the predictions of our theoretical analysis using data on the composition of foreign aid by multilateral and bilateral donors.tied foreign aid; governance; moral hazard; political agency; restricted transfer

    Antibacterial Activity of 04 Medicinal Plant on the IN VITRO Growth of Multi-Resistant Strains Involved in Diarrhea in the Department of Kouto (Ivory Coast)

    This work aims at evaluating in vitro the antibacterial effects of aqueous and hydroethanolic extracts of leaf macerates, Manilkara multinervis, Waltheria indica root bark, Securrinega virosa, and Anogeissus leiocarpa stem bark. These four medicinal plants are traditionally used to treat diarrhea in the canton of North-Niéné (Department of Kouto, Côte d'Ivoire). The antibacterial activities of the various extracts from these plants were carried out on multi-resistant strains (Escherichia coli BLSE, Shigella flexneri BLSE, Staphylococcus aureus meti-R). The methodology consisted of extracting the drugs with a 70% hydroalcoholic solvent and distilled water. Agar diffusion and dilution methods were used for susceptibility testing and determination of CMI and CMB parameters. Agar diffusion and dilution methods were used. By the diffusion method, all four plants were found to be active on at least one of the bacteria tested. The ethanolic extract of M. Multinervis was the most active by inducing a diameter of 15 mm on the growth of S. aureus meti-R. As for the dilution method, the ethanolic extracts of W. indica and M. Multinervis showed bactericidal effects on both S. aureus at 6.25 mg/mL and 3.125 mg/mLrespectively as well as on all other 100 mg/mL germs. Only M. Multinervis recorded the highest activity. This important activity was demonstrated on S. aureus meti-R with a minimum bactericidal concentration of 3.125 mg/mL. These results confirm the traditional use of these plants in the management of diarrheal diseases in the Department of Kouto

    Thoughts on 3D Digital Subplane Recognition and Minimum-Maximum of a Bilinear Congruence Sequence

    International audienceIn this paper we take first steps in addressing the 3D Digital Subplane Recognition Problem. Let us consider a digital plane P : 0 ≤ ax + by − cz + d < c (w.l.o.g. 0 ≤ a ≤ b ≤ c) and a finite subplane S of P dened as the points (x, y, z) of P such that (x, y) ∈ [x0, x1] × [y0, y1]. The Digital Subplane Recognition Problem consists in determining the characteristics of the subplane S in less than linear (in the number of voxels) complexity. We discuss approaches based on remainder values ax+by+d c , (x, y) ∈ [x0, x1] × [y0, y1] of the subplane. This corresponds to a bilinear congruence sequence. We show that one can determine if the sequence contains a value in logarithmic time. An algorithm to determine the minimum and maximum of such a bilinear congruence sequence is also proposed. This is linked to leaning points of the subplane with remainder order conservation properties. The proposed algorithm has a complexity in, if m = x1 −x0 < n = y1 −y0, O(m log (min(a, c − a)) or O(n log (min(b, c − b)) otherwise
