    Dans cette recherche, nous tentons d’évaluer les effets de la crise Ă©conomique mondiale de 2008-2009 sur l’économie sĂ©nĂ©galaise. A l’aide d’un modĂšle d’équilibre gĂ©nĂ©ral calculable statique, nous mettons en exergue les principaux canaux par lesquels cette crise a pu se transmettre Ă  l’économie, Ă  savoir : les prix mondiaux, la demande Ă  l’exportation, les transferts des migrants, l’aide publique au dĂ©veloppement, les investissements directs Ă©trangers. Les rĂ©sultats de notre analyse attestent que la baisse de la demande mondiale Ă  l’exportation et celle des transferts des migrants se rĂ©vĂšlent ĂȘtre les canaux qui ont le plus facilitĂ© la transmission du choc Ă  l’économie sĂ©nĂ©galaise. En effet, celles-ci ont le plus contribuĂ© Ă  dĂ©primer l’activitĂ© Ă©conomique et, en consĂ©quence, favorisĂ© une dĂ©tĂ©rioration des principaux agrĂ©gats macroĂ©conomiques. En outre, elles ont occasionnĂ© l’effritement de l’assiette fiscale de l’Etat qui a vu ses ressources intĂ©rieures baisser

    La stratĂ©gie de rĂ©duction de la pauvretĂ© au SĂ©nĂ©gal va ĂȘtre mise en oeuvre dans un contexte de libĂ©ralisation des Ă©changes commerciaux internationaux notamment dans le secteur agricole et en particulier dans le secteur de l'arachide. Dans ce contexte, nous avons dĂ©veloppĂ© un modĂšle d'Ă©quilibre gĂ©nĂ©ral calculable micro-simulĂ© multi-mĂ©nages du type DecaluwĂ© et al. (1999) permettant d'Ă©valuer l'impact que pourront avoir la libĂ©ralisation de la filiĂšre ainsi que la privatisation de la SociĂ©tĂ© Nationale de Commercialisation des OlĂ©agineux du SĂ©nĂ©gal (SONACOS), politiques prĂ©vues dans l'Accord Cadre sur les mĂ©nages et de faire le lien entre ces rĂ©formes Ă©conomiques, la pauvretĂ© et la distribution de revenu. Ce modĂšle offre beaucoup de flexibilitĂ© en permettant notamment de modifier la distribution des groupes cibles qui n'ont pas Ă  ĂȘtre retenus avant l'exercice de simulation afin d'effectuer l'analyse de pauvretĂ© et d'inĂ©galitĂ© ex post Ă  l'exercice de modĂ©lisation.ModĂšle d'Ă©quilibre gĂ©nĂ©ral calculable, micro-simulation, analyse de pauvretĂ©, distribution de revenu, libĂ©ralisation commerciale, privatisation

    L’objectif de cet article est d’identifier les dĂ©terminants du rendement de lait et de viande des bovins au SĂ©nĂ©gal. Pour cela, nous avons utilisĂ© un modĂšle Ă  correction d’erreur de Johansen. Les rĂ©sultats rĂ©vĂšlent qu’à long terme l’alimentation est un dĂ©terminant significatif du rendement de lait et de viande des bovins. Le prix du lait et celui de la viande bovine agissent Ă©galement positivement sur le rendement de lait et de viande de bovins. En revanche, le prix de la viande est nĂ©gativement liĂ© au rendement de lait des bovins. Mots-clĂ©s: Bovins, DĂ©terminants, Rendement, Lait, ViandeThe purpose of this article is to identify the determinants of the milk and meat yields of cattle in Senegal. To estimate our models, we used a Johansen error correction model. The results reveal that in the long term, feed is a significant determinant of the milk and meat yields of cattle. The price of milk and that of beef also have a positive effect on the yield of milk and beef. On the other hand, the price of meat is negatively linked to the milk yield of cattle.

    COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

    Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≀ 18 years: 69, 48, 23; 85%), older adults (≄ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

    Artificial insemination and economic growth in Senegal

    No full text
    International audienceUsing a general dynamic equilibrium model, this article simulates the impact of Senegal’s artificial insemination program on economic growth and household wellbeing. The results attest to a rise in the supply of cows, meat, processed milk, and leather. The price effects seem to override the revenue effects. Indeed, the households benefitting from this program are those in silvopastoral and urban zones, and in the groundnut-growing belt.À l’aide d’un modĂšle d’équilibre gĂ©nĂ©ral dynamique, l’article simule l’impact du programme d’insĂ©mination artificielle du SĂ©nĂ©gal sur la croissance Ă©conomique et le bien-ĂȘtre des mĂ©nages. Les rĂ©sultats attestent d’une hausse de l’offre de bovins, de viande, de lait transformĂ© et de cuirs. Les effets prix semblent l’emporter sur les effets revenus. En effet, les mĂ©nages gagnants de ce programme sont ceux des zones sylvo-pastorales, urbaines et du bassin arachidier

    Rainfall and economic growth and poverty: Evidence from Senegal and Burkina Faso

    No full text
    This paper assesses the effects of rainfall shocks on poverty in Burkina Faso and Senegal using a computable general equilibrium model. An index quantifying effects of rainfall fluctuations shows that, due to a predicted increase in annual rainfall, Senegal will experience a decline in poverty, while Burkina Faso will experience an increase in its poverty rate in conjunction with a trend of declining rainfall. The implementation of mitigating policies in Burkina Faso can affect the rate of increase in poverty, but future rainfall trends are expected to have positive effects on poverty in Senegal and negative effects in Burkina Faso.Non-PRIFPRI1; AGRODEPMTI

    RAINFALL FLUCTUATIONS AND ECONOMIC GROWTH: EVIDENCE FROM SENEGAL

    No full text
    In this paper, we simulate and evaluate the impact of extreme rainfall events on various sectors in the economy; factors of production remuneration and economic growth in Senegal. A dynamic general equilibrium model is developed which includes an index linking rainfall fluctuations to total productivity factor (TPF) and factor market. Based on rainfall trends during the past three decades, we run simulations to assess the effects of rainfall values on GDP growth. The results show that extreme events in rainfall pattern deeply affect GDP growth in Senegal; sharp drops in rainfall lead to declining GDP and periods of abundant rainfalls are marked by better performance in term of GDP. However, rainfall drops lead to losses in GDP growth in comparison to gains in GDP growth due to rainfall surplus
