Manager bonding and the technical efficiency of cooperative credit unions-parametric and non-parametric analyses

We engage parametric and non-parametric approaches to analyze unbalanced data (2012–16) from 225 credit unions in Ghana. The non-parametric analysis involves using data envelopment analysis to assess the technical efficiency of the credit unions. We show that most of them are not technically efficient. The average five-year overall technical efficiency and pure technical efficiency scores of a credit union are 0.87 and 0.91 respectively. Targeted at inquiring whether manager bonding significantly connects with the technical efficiency of credit unions, the parametric analysis which involves the use of probit and logit regression techniques, shows that, generally, the bonding of managers hurts the technical efficiency of credit unions. We are, thus, led to the conclusion that bonding of managers may not be in the best interest of credit unions in Ghana.     

Labour commodification,differentiation, and marginalization of the peasantry in Sella Limba (Sierra Leone) from 1950 to the present

In Sierra Leone, migration to diamond fields and the development of cash crops have contributed to the increasing integration of the peasantry in the national and global economy. Based on the study of a small northern chiefdom, Sella Limba, we describe how the labour commodification have led to the perversion of “traditional” social relations based on anteriority, and to the break‐up of large domestic groups into smaller, more precarious ones. At the same time, manual agriculture has been marginalized by massive cheap rice imports and remained very low in capital intensity. In this context, we show how low labour productivity curtails opportunities for long‐term social and economic differentiation. Farmers combine “modern” and “traditional” social relations, developing hybrid accumulation strategies that are sometimes close to mere survival.     

Pane e Cioccolata: The Impact of Native Attitudes on Return Migration

This paper addresses the link between native attitudes and return migration. We exploit the variation in xenophobia using information on media consumption by migrants in Italy. A widely documented crime provides a quasi‐experimental setting to identify the impact of Italian attitudes on migrants’ settlement intentions. Our results suggest a significant effect of anti‐immigrant attitudes on the intended duration of stay in the host country. The impact is more pronounced for low‐skilled migrants, which has consequences for how migration affects the long‐run convergence between sending and destination countries.     

Improving the productivity of vertisols in the Accra plains of Ghana using leguminous cover crops

The productivity of the Vertisols of the Accra plains is low, in spite of its high potential fertility. This could be attributed to physical constraints and low organic matter content. A study was conducted at the Agricultural Research Centre, Kpong, to assess the suitability of Mucuna pruriens, Mimosa invisa and Stylosanthes guianensis, in short fallows, for improving the fertility, physical properties, moisture conservation and weed control in the case of these soils. Mucuna had the highest biomass of 5.3tha^?1, as opposed to 4.1tha^?1 under natural fallow. The mucuna and stylosanthes biomass had comparatively higher total N values (240.75 and 203.51kgha^?1, respectively) than mimosa and natural fallow (152.46 and 162.74kgha^?1, respectively). Soil organic carbon, one year after the incorporation of cover crops, was found to be relatively higher under the cover crops (mucuna, stylosanthes and mimosa) than it was under natural fallow. Bulk densities were thus lower under the cover crops than they were under natural fallow. Also, soils under the cover crops had higher total porosity, water infiltration rates and moisture storage than they did under natural fallow. Weed cover, 115 days after planting maize, was significantly lower in plots previously under Mucuna pruriens than it was under natural fallow, Stylosanthes guianensis and Mimosa invisa. There was a negative linear correlation between cover crop biomass and weed density (R ² = 0.593–0.805). Grain and stover yields of maize were higher under Mucuna pruriens than they were under natural fallow (138 and 70 per cent higher, respectively). Burning of the natural fallow resulted in greater weed growth than when the material was worked into the soil (41 and 8 per cent, respectively). Grain yield was significantly greater under mucuna than it was under natural fallow (3.1 and 1.3tha^?1, respectively).     

The Global Setting and African Economic Growth

This paper reviews the evidence on the importance of the globalsetting for the economic growth of African economies, particularlyin the light of the increasing salience of globalisation. Althoughexport promotion strategies are found to be growth enhancingfor African economies, available evidence suggests that it isthe manufacturing component that really seems to matter. Theglobal-related factors with adverse effects include terms oftrade deterioration, economic instabilities of capital (investment)and imports, high world interest rates, real exchange rate misalignment,diminishing external aid flows into countries with sound policies,large external debt and high export taxes. The World Trade Organisationframework also matters for the growth prospects of African countries.The current time-bound exemptions accorded most African countriesunder the framework are steps in the right direction.     

Democracy and growth in Africa: Implications of increasing electoral competitiveness

Estimating a 1975–2004 decadal panel data in an augmented production-function framework, the paper finds that indexes of electoral competitiveness exhibit U-shape relationships with GDP growth, implying quite different “intermediate” and “advanced”-level effects of reforms in Africa.     

Groundnut consumption frequency in Ghana

Groundnut (peanut) is an important food and oil crop in Ghana, but little is known about the factors influencing consumption. The study surveyed market participants; investigated the frequency and forms of groundnut consumed; and evaluated the factors influencing consumers’ decisions to eat groundnuts in Ghana. About 80% of respondents consume groundnut and/or its products at least once a week and 32.0% consume it three times a week. Logistic models showed that age, education and the form in which groundnuts are consumed influence the frequency of groundnut consumption. Total revenue and the form in which groundnut is eaten influence farmers consumption decision whereas groundnut consumption by poultry farmers is influenced by knowledge of the health effects of groundnuts on birds and the form in which groundnut is eaten by the poultry producers. Processors’ frequency of consumption is influenced by the form in which groundnut is consumed and their knowledge of reasons for sorting. The results are important for market segmentation for demand projection along the marketing chain.
