Institutions and the Economic Performance of Central African Countries  [PDF]
Chérif Sidy Kane, Elomo Zogo Thérèse, Idrissa Yaya Diandy
Theoretical Economics Letters (TEL) , 2019, DOI: 10.4236/tel.2019.91004
Abstract: The purpose of this paper is to examine the combined effect of political and economic institutions on the economic performance of the countries of Central Africa. To do this, we use dynamic panel data over the period 1996-2013. Using Principal Component Analysis (PCA) to understand the multidimensionality of institutions through a composite indicator, and applying the estimation technique based on the Generalized Moment Method (GAM) to capture the impact of institutions on economic performance, we arrive at the following result: analyzed individually or in combination, institutions constitute a real obstacle to economic performance in Central Africa.

Mouhamadou Moustapha Cisse, Rachid El Kabouss, Yaya Kane, Sidy Mouhamed Seck, Ahmed Tall Lemrabott, Maria Faye, El Hadji Fary Ka, Ansoumana Diatta, Abdou Niang, Boucar Diouf
Open Journal of Nephrology (OJNeph) , 2015, DOI: 10.4236/ojneph.2015.54017
Abstract: Summary: Tuberculosis is a common infectious disease in chronic hemodialysis due to alteration of the immune system associated with chronic kidney disease. The objectives of this study are to determine the prevalence of tuberculosis in chronic hemodialysis patients and to identify its diagnostic and therapeutic difficulties. Methods and patients: This was a descriptive retrospective study over a period of 20 years (1994-2014). It includes the records of periodic hemodialysis patients in the Nephrology Department of the Aristide Le Dantec University Teaching Hospital in Dakar which clinical symptoms and laboratory favor tuberculosis. Results: Of 258 chronic hemodialysis patients treated in Hospital Aristide Le Dantec hemodialysis center, 29 cases (11.4%) of tuberculosis disease are diagnosed. The mean age is 43.21 ± 12.48 years, and the sex-ratio is 0.8. The median time to onset of tuberculosis after initiation of hemodialysis is 22.86 ± 28.86 months. The diagnosis of tuberculosis is sure only in 17% of cases. Extra-pulmonary sites are found in 79% of cases. The average duration of treatment is 9.39 ± 1.64 months (6 - 13 months). Various treatment protocols are adopted. Mortality is 21%, 50% due to disseminated tuberculosis. Conclusion: The diagnosis of tuberculosis in the chronic hemodialysis patients is often difficult due to the atypical symptoms, the frequency of extra-pulmonary location and the lack of evidence of sure diagnosis.

Kane Yaya, Cisse Mouhamadou Moustapha, Seck Sidy Mohamed, Lemrabott Ahmed Tall, Faye Maria, Hounsounou Christian, Diallo Kalilou, Ka El Hadji Fary, Niang Abdou, Diouf Boucar
Open Journal of Nephrology (OJNeph) , 2016, DOI: 10.4236/ojneph.2016.62005
Abstract: Introduction: Measuring the quality of life (QOL) in recent years has become an indispensable tool in monitoring patients suffering from chronic diseases. We conducted this study to assess QOL of patients undergoing peritoneal dialysis in Dakar, and to identify associated factors. Patients and Methods: This is a cross-sectional study which was carried out from 10 to 30 June, 2011 in the peritoneal dialysis unit at university hospital in Dakar. We included all patients with end-stage renal disease (ESRD) of any age, who were on PD since at least six months and who gave their consent. The QOL was assessed using the Kidney Disease Quality of Life Short-Form 1.2 (KDQoL-SF). Results: Sixteen patients were included with a mean age of 50.25 ± 13.48 years and a sex-ratio of 1.27. Considering SF-36, the overall mean score (SMG) was 60.11 ± 15.96 with a Mean Physical Component Summary Scale of 53.66 ± 16.98 and a Mental Component Summary Scale of 70.85 ± 6.14. Concerning the KDQoL-SF, the global mean score was 61.83 ± 19.35 with a mean physical score of 50.55 ± 16.52 and a mean mental score of 62.52 ± 21.53. The mean dialysis specific dimension score was 62.52 ± 21.53 and the mean mental health score was 85.93 ± 12.06. Age, weight, level of instruction and social support were correlated with a worse QOL. Conclusion: This study showed an alteration of our PD patients’ QOL, particularly in their physical health. However, the number of patients included in the study is not enough to permit a formal conclusion.

Theoretical Economics Letters (TEL) , 2016, DOI: 10.4236/tel.2016.65105
Abstract: This paper examines the impact of remittances on financial sector development in a panel of 19 developing countries. Contrary to previous studies that focus on mean effects, it uses quantile regression methodology to examine whether the effect of remittances on financial development is the same for less and more financially developed countries. The results point out that remittances promote financial development only in less financially developed countries. Further, the effect of income is positive and larger in less financially developed countries. Trade openness is positively related to financial development while inflation and urbanization are negatively related to it.
Manufacturing and Economic Growth in ECOWAS Countries: A Test of Kaldor’s First Law  [PDF]
Yaya Keho
Modern Economy (ME) , 2018, DOI: 10.4236/me.2018.95057
Abstract: Kaldor’s first growth law posits that the growth rate of an economy is positively related to the growth rate of its manufacturing sector. Since the sixties, this relationship has been examined in a large number of studies using a wide variety of data sets and econometric methods. This paper examines the validity of this law for 11 ECOWAS member countries over the period 1970-2014 by employing an Autoregressive Distributed Lag bounds test approach to cointegration and Granger causality tests. The results show that manufacturing output growth causes positively economic growth and non-manufacturing output growth, thereby providing support for Kaldor’s first growth law. The policy recommendation from the results of the study is that structural transformation in favour of industrial production activities would help to accelerate economic growth in ECOWAS countries.
Impact of Government Spending on Private Consumption: Evidence from ECOWAS Countries  [PDF]

Modern Economy (ME) , 2019, DOI: 10.4236/me.2019.103041
Abstract:

This study examines the impact of government spending on household consumption for the Economic Community of West African States (ECOWAS). As a modelling strategy, we use the Common Correlated Effect Mean Group (CCEMG) estimator that accounts for both parameter heterogeneity and cross-sectional dependence. The study provides various pieces of evidence through whole-panel and country-level analyses. The panel estimates indicate that government consumption has, on average, a negative effect on private consumption, implying that government and private consumption are substitutes. Country-level results reveal, however, considerable heterogeneity in the degree of substitutability across countries. They show crowding out effects in six countries, crowding in effects in one country and no significant effect in five countries. Therefore, government consumption is not a good instrument to stimulate aggregate demand and economic growth in ECOWAS countries.

Theoretical Economics Letters (TEL) , 2019, DOI: 10.4236/tel.2019.94061
Abstract: This study investigates the determinants of private consumption expenditure in Cote d’Ivoire using time series data from 1970 to 2016. The Autoregressive Distributed Lags bounds testing approach to cointegration is employed to depict the presence of a long run relationship between private consumption and its determinants and an error correction model is estimated to derive short run dynamics. The results show the presence of a long run relationship among the selected variables. In the long run, current income, wealth and government consumption expenditure play a positive role in determining private consumption, with the effect of current income being higher. Furthermore, consumption expenditure is negatively affected by inflation rate and real interest rate on deposits. In the short run, only income and wealth appear to have positive effects on private consumption while the effects of government consumption, inflation and interest rate were found to be insignificant. This study provides evidence for government to improve the level of private consumption.

Abstract: Introduction: High blood pressure (HBP) is a worldwide health issue responsible of high cardiovascular morbidity and mortality. Even though essential HBP is far the most frequently reported in patients, secondary causes must be known because of their severity and the possibility of aetiological treatment. No recent epidemiological data are available about secondary causes of HBP in black African populations. The aim of this study was to describe aetiological patterns of secondary HBP in patients followed at Saint-Louis Hospital. Patients and Method: We conducted a retrospective and descriptive study in regional hospital of Saint-Louis. All patients aged ≥15 years old admitted from January 1st 2011 to January 31st 2015 in internal medicine, nephrology, emergency and cardiology departments were included. Clinical, paraclinical data and patients outcomes were collected from medical records. Hypertension was defined according to JNC8 criteria. Secondary HBP was considered if explorations identified a clear aetiology to hypertension. Statistical analysis was done with Excel 2010 and STATA 12.0. Results: We included 9253 patients with mean age of 35 ± 12 years (15 - 83 years) and sex-ratio of 1.6. Overall 67.5% of patients had hypertension and secondary causes were found in 10.5% of them. The majority of patients presented clinical symptoms suggesting a secondary cause of HBP and first-line laboratory explorations were normal in half of cases. Renal diseases were responsible for 79.1% of secondary HBP cases mainly dominated by glomerulonephritis (22.6%), vascular nephropathies (18.7%) and autosomal dominant polycystic kidney disease (5.8%). They were followed by preeclampsia (13.6%) and endocrinal aetiologies such as hyperthyroidism (5.8%), hypercorticism (0.5%), pheochromcytoma (0.5%), primary hyperparathyroidism (0.4%) and Conn’s adenoma (0.1%). Combination of ≥3 antihypertensive drugs was necessary in 71.5% of cases and surgical treatment was performed in three patients. Blood pressure was normalized in only 27.7% of patients. Conclusion: Secondary causes are frequent in our young patients with HBP. In the majority of patients complete clinical examination and minimal laboratory investigations recommended by World Health Organisation can give an aetiological orientation that needs further radiological and hormonal explorations.

Faye Moustapha, Lemrabott Ahmed Tall, Kane Yaya, Cisse Mouhamadou Moustapha, Seck Sidy Mohamed, Faye Maria, Daher Abdoul Karim Omar, Fall Khodia, Sakho Binta, Keita Rick Alex Ismael, Mbengue Mansour, Niang Abdou, Diouf Boucar, Ka Elhadji Fary
Open Journal of Nephrology (OJNeph) , 2018, DOI: 10.4236/ojneph.2018.82004
Abstract: Introduction: Intradialytic hypertension is defined as elevation of blood pressure to more than 10 mmHg in the post-dialysis period as compared to the pre-dialysis one. It is an important factor of morbidity and mortality in hemodialysis patients. The aim of our study is to assess the prevalence and associated factors of intradialytic hypertension. Patients and methods: This is a descriptive and analytical cross-sectional study that was conducted over a period of 3 weeks in the hemodialysis units of Aristide Le Dantec Hospital in Dakar and Regional Hospital Center in Ziguinchor. Chronic he-modialysis patients who are at least 18 years old and agreed to participate in study have been included. Patients who did not have 4 measures or those who decided to withdraw from the study were excluded. Intradialytic hypertension was restrained by an increase in systolic blood pressure immediately after the hemodialysis session > 10 mmHg compared to that recorded before session, with a repetition of this phenomenon for at least 4 hemodialysis sessions. Results: Our study included 539 hemodialysis sessions for 93 hemodialysis patients with a mean age of 48.72 ± 14.06 years and a sex ratio (M/F) of 1.21. The mean duration of dialysis was 64.22 ± 45.63 months. Hypertensive nephropathy was significantly common, noted in 38.7% (36 patients). Mean inter dialytic weight gain was 2.04 ± 1.06 kg, and the average dry weight was 62.71 ± 13.69 kg. The average hemoglobin level was 9.27 ± 1.91 g/dl. The mean albumin level was 35.4 ± 7.48 g/l. Nineteen (19) patients were administered erythropoietin stimulating agents (20.4%), and 59 patients were given antihypertensive drugs (63.4%). An elevation of more than 10 mmHg of post-dialysis BP compared to pre-dialysis was noted in 179 sessions, which is 33.2 per 100 hemodialysis sessions. IDH was noted in 21 patients, which represents 22.6%. The factors associated with IDH were as follows: high post-dialysis pulse pressure (PP) (p = 0.0008), pre-dialysis systolic-diastolic hypertension (p = 0.004), pre-dialysis pure systolic hypertension (p = 0.01), post-dialysis hypertension (p = 0.02), and hypoalbuminemia (p = 0.049). Conclusion: Although recognized for many years, the intradialytic hypertension is often neglected. However, it is common in our cohort of chronic hemodialysis with several associated factors. Its management is essential and will necessarily pass through adequate management of the blood volume.
Tax Structure and Economic Growth in Cote dIvoire: Are Some Taxes Better Than Others?
Yaya KEHO
Asian Economic and Financial Review , 2011,
Abstract: This paper examines the relationships between taxation and output in C te d’Ivoire during the period 1960-2006. The bounds testing approach to cointegration devised by Pesaran et al. (2001) showed that tax variables, except direct tax, and real GDP are cointegrated and positively related in the long-run. The results of Granger causality tests indicated bidirectional causality between tax revenues and output in the long-run, implying a virtuous circle of tax and GDP. Direct taxes, however, did not cause GDP both in the short and long-run. These findings suggest that i) the tax revenues and, therefore, budget deficit, depend upon the economic activity, and ii) switching the tax burden from direct to indirect taxes is likely to have a positive effect on the economic output.
