Impact de la crise économique mondiale de 2008-2009 sur l'économie sénégalaise
Dans cette recherche, nous tentons dâĂ©valuer les effets de la crise Ă©conomique mondiale de 2008-2009 sur lâĂ©conomie sĂ©nĂ©galaise. A lâaide dâun modĂšle dâĂ©quilibre gĂ©nĂ©ral calculable statique, nous mettons en exergue les principaux canaux par lesquels cette crise a pu se transmettre Ă lâĂ©conomie, Ă savoir : les prix mondiaux, la demande Ă lâexportation, les transferts des migrants, lâaide publique au dĂ©veloppement, les investissements directs Ă©trangers. Les rĂ©sultats de notre analyse attestent que la baisse de la demande mondiale Ă lâexportation et celle des transferts des migrants se rĂ©vĂšlent ĂȘtre les canaux qui ont le plus facilitĂ© la transmission du choc Ă lâĂ©conomie sĂ©nĂ©galaise. En effet, celles-ci ont le plus contribuĂ© Ă dĂ©primer lâactivitĂ© Ă©conomique et, en consĂ©quence, favorisĂ© une dĂ©tĂ©rioration des principaux agrĂ©gats macroĂ©conomiques. En outre, elles ont occasionnĂ© lâeffritement de lâassiette fiscale de lâEtat qui a vu ses ressources intĂ©rieures baisser
Une analyse préliminaire d'impacts de la libéralisation de la filiÚre arachide au Sénégal: un modÚle d'équilibre général calculable multi-ménages
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
Determinants of milk and meat yields of cattle in Senegal
Lâobjectif de cet article est dâidentifier 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 dâerreur de Johansen. Les rĂ©sultats rĂ©vĂšlent quâĂ long terme lâalimentation 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-clés: Bovins, Déterminants, 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 60â109 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:
âTypicalâ 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 (â€â18 years: 69, 48, 23; 85%), older adults (â„â70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each Pâ<â0.001). 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
International audienceUsing a general dynamic equilibrium model, this article simulates the impact of Senegalâs 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.Ă lâaide dâun modĂšle dâĂ©quilibre gĂ©nĂ©ral dynamique, lâarticle simule lâimpact du programme dâinsĂ©mination artificielle du SĂ©nĂ©gal sur la croissance Ă©conomique et le bien-ĂȘtre des mĂ©nages. Les rĂ©sultats attestent dâune hausse de lâoffre de bovins, de viande, de lait transformĂ© et de cuirs. Les effets prix semblent lâemporter 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
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
