The impact of banking reforms on competition and efficiency of Ghanaâs banking sector
African countries are pursuing financial reforms to address inhibitions to competition and efficiency of their banking sectors. This thesis focuses on Ghana which recently implemented deregulation reforms including the introduction of universal banking, the adoption of an open licensing policy to enhance contestability and competition, and the abolition of secondary reserves;
and examines the impact of these reforms on banking competition and efficiency. The study uses a comprehensive and unique panel dataset of 25 banks for the period 2000-2014 which captures the pre- and post-reform periods. The study employs the persistence of profit and Boone indicator models of competition to analyse competitive conditions in the loans market. The empirical results suggest that competition initially
increased following the reforms but subsequently declined as a result of macroeconomic weaknesses, in particular high interest rates, which was partly impacted by the indirect effects of the global financial crisis. The study also uses stochastic frontier analysis to examine the efficiency impacts of the reforms, as well as the role of bank ownership and size in influencing efficiency
levels. Different deregulation reform indices are constructed using survey data and coding rules from two international databases on banking regulations and reforms, and captured as inefficiency covariates together with ownership and bank size in the one-step Battese-Coelli (1995) model. The findings point to an overall increase in cost efficiency following the reforms although there is non-uniformity in efficiency-impacts from the different policies. Foreign and regional banks are found to be marginally more efficient than private domestic and state-owned banks. Bank size was found
to positively impact cost efficiency while the global financial crisis had an adverse impact on efficiency.
The policy implications are that for African countries to benefit from financial deregulation reforms, there is the need for the reforms to be anchored on strong macroeconomic fundamentals, institutional initiatives which support these reforms, strong credit environments and appropriate sequencing of reforms
Costs of continuing RTS,S/ASO1E malaria vaccination in the three malaria vaccine pilot implementation countries.
BackgroundThe RTS,S/ASO1E malaria vaccine is being piloted in three countries-Ghana, Kenya, and Malawi-as part of a coordinated evaluation led by the World Health Organization, with support from global partners. This study estimates the costs of continuing malaria vaccination upon completion of the pilot evaluation to inform decision-making and planning around potential further use of the vaccine in pilot areas.MethodsWe used an activity-based costing approach to estimate the incremental costs of continuing to deliver four doses of RTS,S/ASO1E through the existing Expanded Program on Immunization platform, from each government's perspective. The RTS,S/ASO1E pilot introduction plans were reviewed and adapted to identify activities for costing. Key informant interviews with representatives from Ministries of Health (MOH) were conducted to inform the activities, resource requirements, and assumptions that, in turn, inform the analysis. Both financial and economic costs per dose, cost of delivery per dose, and cost per fully vaccinated child (FVC) are estimated and reported in 2017 USD units.ResultsAt a vaccine price of 1.70 (Kenya) to 0.23 (Malawi) to 11.50 (Ghana) to $13.69 (Malawi) per FVC. Estimates of economic costs per dose are between three and five times higher than financial costs. Variations in activities used for costing, procurement add-on costs, unit costs of per diems, and allowances contributed to differences in cost estimates across countries.ConclusionCost estimates in this analysis are meant to inform country decision-makers as they face the question of whether to continue malaria vaccination, should the intervention receive a positive recommendation for broader use. Additionally, important cost drivers for vaccine delivery are highlighted, some of which might be influenced by global and country-specific financing and existing procurement mechanisms. This analysis also adds to the evidence available on vaccine delivery costs for products delivered outside the standard immunization schedule
Molecular Characterization of Circulating Yellow Fever Viruses from Outbreak in Ghana, 2021â2022
Yellow fever virus, transmitted by infected Aedes spp. mosquitoes, causes an acute viral hemorrhagic disease. During October 2021âFebruary 2022, a yellow fever outbreak in some communities in Ghana resulted in 70 confirmed cases with 35 deaths (case-fatality rate 50%). The outbreak started in a predominantly unvaccinated nomadic community in the Savannah region, from which 65% of the cases came. The molecular amplification methods we used for diagnosis produced full-length DNA sequences from 3 confirmed cases. Phylogenetic analysis characterized the 3 sequences within West Africa genotype II; strains shared a close homology with sequences from Cote dâIvoire and Senegal. We deployed more sensitive advanced molecular diagnostic techniques, which enabled earlier detection, helped control spread, and improved case management. We urge increased efforts from health authorities to vaccinate vulnerable groups in difficult-to-access areas and to educate the population about potential risks for yellow fever infections
Adaptation of the Wound Healing Questionnaire universal-reporter outcome measure for use in global surgery trials (TALON-1 study): mixed-methods study and Rasch analysis
BackgroundThe Bluebelle Wound Healing Questionnaire (WHQ) is a universal-reporter outcome measure developed in the UK for remote detection of surgical-site infection after abdominal surgery. This study aimed to explore cross-cultural equivalence, acceptability, and content validity of the WHQ for use across low- and middle-income countries, and to make recommendations for its adaptation.MethodsThis was a mixed-methods study within a trial (SWAT) embedded in an international randomized trial, conducted according to best practice guidelines, and co-produced with community and patient partners (TALON-1). Structured interviews and focus groups were used to gather data regarding cross-cultural, cross-contextual equivalence of the individual items and scale, and conduct a translatability assessment. Translation was completed into five languages in accordance with Mapi recommendations. Next, data from a prospective cohort (SWAT) were interpreted using Rasch analysis to explore scaling and measurement properties of the WHQ. Finally, qualitative and quantitative data were triangulated using a modified, exploratory, instrumental design model.ResultsIn the qualitative phase, 10 structured interviews and six focus groups took place with a total of 47 investigators across six countries. Themes related to comprehension, response mapping, retrieval, and judgement were identified with rich cross-cultural insights. In the quantitative phase, an exploratory Rasch model was fitted to data from 537 patients (369 excluding extremes). Owing to the number of extreme (floor) values, the overall level of power was low. The single WHQ scale satisfied tests of unidimensionality, indicating validity of the ordinal total WHQ score. There was significant overall model misfit of five items (5, 9, 14, 15, 16) and local dependency in 11 item pairs. The person separation index was estimated as 0.48 suggesting weak discrimination between classes, whereas Cronbach's α was high at 0.86. Triangulation of qualitative data with the Rasch analysis supported recommendations for cross-cultural adaptation of the WHQ items 1 (redness), 3 (clear fluid), 7 (deep wound opening), 10 (pain), 11 (fever), 15 (antibiotics), 16 (debridement), 18 (drainage), and 19 (reoperation). Changes to three item response categories (1, not at all; 2, a little; 3, a lot) were adopted for symptom items 1 to 10, and two categories (0, no; 1, yes) for item 11 (fever).ConclusionThis study made recommendations for cross-cultural adaptation of the WHQ for use in global surgical research and practice, using co-produced mixed-methods data from three continents. Translations are now available for implementation into remote wound assessment pathways
