Effect of exchange rate on inflation in the inflation targeting framework: Is the threshold level relevant?

The continuous depreciation of the exchange rate in Ghana has raised concern about its effect on inflation and the economy at large. This paper examines the threshold effect of exchange rate pass-through (ERPT) on inflation using a monthly data from January 2002 to December 2018. The relevance of the exchange rate threshold in the Taylor rule has also been examined. Using the threshold autoregressive (TAR) method, the results of the ERPT model revealed that exchange rate depreciation beyond a monthly threshold of 0.70% has a significant positive pass-through effect on inflation, which gives credence to the relevance of threshold level. The results of the monetary policy rule model also showed that regardless of the threshold level of 0.51%, the exchange rate significantly influences the monetary policy rate positively. Therefore, paying proper attention to the exchange rate in the policy rule despite the threshold (0.51%) will prevent the exchange rate depreciation from exceeding the optimal level (0.70%) and hence no ERPT on inflation. Based on these findings, it is suggested that monetary regulators should view the exchange rate at any level essential to adjust the policy rate

Money supply, budget deficit and inflation dynamics in Ghana: An empirical investigation

The paper investigates the long run dynamics of money supply, budget deficit and inflation in Ghana. It also tests the validity of the classical, monetary and fiscal theories of price level within the vector error correction framework. Using quarterly data from 1999Q1 to 2019Q4, the paper employs Granger causality test and the vector error correction model (VECM) for the analysis. The results from the VECM show that budget deficit has a significant positive effect on inflation while money supply negatively affect it. By contrast, inflation exerts a positive and negative effect on budget deficit and money supply, respectively. The results from the impulse response function also indicate that inflation responds more positively to budget deficit shocks. However, it tends to respond negatively to money supply (M2) shocks. Also, budget deficit responds positively (negatively) to inflation (money supply [M2]) shocks. Furthermore, money supply responds positively (negatively) to budget deficit (inflation) shocks. Based on the weak exogeneity test, the result favours the fiscal theory of the price level in explaining the nexus between money supply, budget deficit and inflation in Ghana. A corollary of our results is that a reduction in government expenditure coupled with restrictive bureaucratic nature of government officials have the tendency of ensuring favourable and stable inflation in Ghana

The effect of smallholder livestock production on income of farm households in Northern Ghana

This paper investigates the effect of smallholder livestock production on income among farm households in northern Ghana. Questionnaires were administered to 300 household heads and ordinary least squares estimation technique was applied to the dataset. The dependent variable was income and measured by total annual income received from farm and non-farm activities by household heads. The independent variable of interest was tropical livestock unit measured by flock size. We also included farm size, household size, gender, age, educational level, distance to market, dependency ratio and access to formal credit as control variables. We found that smallholder livestock production and farm size increase income whilst distance to market and dependency ratio reduce income. Based on evidence of the positive relationship between livestock pro-duction and household income in this paper, it is recommended that policies to promote smallholder livestock production should be embarked upon to increase income. This is likely to improve livelihood and reduce poverty among the poor rural folks in the northern regions of Ghana

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Greening the future: Unveiling the link between industrial structure upgrading and pollution emission in sub-Saharan Africa

AbstractIndustrial structure upgrading (ISU) in sub-Saharan Africa (SSA) has been improving in recent years, making it essential to examine how such upgrading influences pollution emissions in SSA. However, studies concerning the environment in SSA have overlooked this important role. Consequently, achieving the Sustainable Development Goals becomes futile if such critical issues are not given due attention in policy discourse. In light of this, this study examined the effect of ISU on pollution emissions in 28 SSA countries using data from 1980 to 2020 and employed two key measures of ISU as contributions to the literature. Regarding the analysis, the fixed effects, random effects, and feasible generalized least squares estimators and the Dumitrescu and Hurlin (D-H) causality test were employed. The results show that ISU improves the sustainable environment by reducing pollution emissions in SSA by 0.03–0.04%. Furthermore, economic growth (EG) increases pollution emissions by 0.63–0.72%, but after reaching a threshold level of 0.10%, EG reduces pollution emissions by 0.03–0.04%. This confirms the EKC hypothesis in the selected SSAs. The D-H causality analysis also reveals a bidirectional relationship between ISU and pollution emissions. Based on these results, we conclude that upgrading the industrial structure in SSA is crucial for a clean and sustainable environment

Spatial and Seasonal Patterns of Tick Infestations in Kassena-Nankana Livestock

The ability of ticks to adapt to different ecological zones, coupled with the spread of infectious pathogens negatively affects livestock production and thus, there is a need for better control strategies. However, control measures within a geographical region can only be effective if there is available information on tick population dynamics and ecology. This study focused on ticks infesting livestock in the Kassena-Nankana Districts of the Upper East Region of Ghana. The ticks were morphologically identified, variables such as season, animal host, and predilection sites were recorded, and the data were analyzed using STATA version 13. Out of 448 livestock examined, tick infestation in cattle was (78.60%), followed by sheep (25%) and goats (5.88%). A total of 1,550 ticks including nymphs (303) and adults (1,247) were collected. Adult ticks were found to be significantly associated with season (p<0.001), with a high burden in the wet season. The nymph burden and body parts of livestock hosts were significantly associated with more nymphs collected from male animals than females (p<0.001). Three genera of ticks, Amblyomma (62.97%), Hyalomma (18.71%), and Rhipicephalus (18.32%) were morphologically identified with the most predominant tick species recorded as Amblyomma variegatum (62.97%). Matured A. variegatum was sampled primarily in the wet season with their predilection site as the udder/scrotum (p<0.001). However, adult Hyalomma truncatum was observed to have a significant association with the anal region (p<0.001). Findings from this study are essential for formulating tick control measures to prevent the spread of infectious pathogens

Frailty syndrome and associated factors among patients with hypertension: A cross‐sectional study in Kumasi, Ghana

Abstract Background and Aim Frailty is a condition marked by accumulation of biological deficits and dysfunctions that come with aging and it is correlated with high morbidity and mortality in patients with cardiovascular diseases, particularly hypertension. Hypertension continues to be a leading cause of cardiovascular diseases and premature death globally. However, there is dearth of literature in sub‐Saharan Africa on frailty syndrome among hypertensives on medication. This study evaluated frailty syndrome and its associated factors among Ghanaian hypertensives. Methods This cross‐sectional study recruited 303 patients with hypertension from the University Hospital, Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana. Data on sociodemographic, lifestyle and clinical factors were collected using a well‐structured questionnaire. Medication adherence was measured using Adherence in Chronic Disease Scale, and frailty was assessed by Tilburg Frailty Indicator. Statistical analyses were performed using SPSS Version 26.0 and GraphPad prism 8.0. p‐value of < 0.05 and 95% confidence interval (CI) were considered statistically significant. Results The prevalence of frailty was 59.7%. The proportion of high, medium and low medication adherence was 23.4%, 64.4% and 12.2%, respectively. Being ≥ 70years (adjusted odds ratio [aOR]: 8.33, 95% CI [3.72–18.67], p < 0.0001), unmarried (aOR: 2.59, 95% CI [1.37–4.89], p = 0.0030), having confirmed hypertension complications (aOR: 3.21, 95% CI [1.36–7.53], p = 0.0080), medium (aOR: 1.99, 95% CI [1.05–3.82], p = 0.0360) and low antihypertensive drug adherence (aOR: 27.69, 95% CI [7.05–108.69], p < 0.0001) were independent predictors of increased odds of developing frailty syndrome. Conclusion Approximately 6 out of 10 Ghanaian adult patients with hypertension experience frailty syndrome. Hypertension complications, older age, being unmarried, and low antihypertensive drug adherence increased the chances of developing frailty syndrome. These should be considered in intervention programmes to prevent frailty among patients with hypertension
