Our strategy is empirical. Our model is based on an accounting equation derived from the SIR model, and estimates the relationship between the growth of the daily COVID-19 con rmed cases on the one hand, and climatic variables (such as the daily average temperature and the wind speed) and governments responses to COVID-19 on the other hand. We also develop a theoretical approach to test the presence of a threshold in the effect of the temperature on the COVID-19 spread. Using a panel data on a sample of 294 territories overs 106 days (from 22 January, 2020 to 06 May, 2020), we nd signi cant negative effect of temperature and temperature variability and signi cant positive effect of wind speed and precipitation on the growth of the COVID-19 con rmed cases. We also nd that governments responses are associated to a lower growth of con rmed cases. But we do not nd any universally applicable threshold effect in the relationship between the average temperature and the con rmed cases growth.

Pour répondre à ces questions nous avons proposé une nouvelle approche de mesure du degré de synchronisation multilatérale des cycles économiques, et nous avons estimé un modèle de type panel dynamique par la méthode des moments généralisés conditionnels en deux étapes proposés par Arellano et Bond (1991), Bover et Blundell (1998). Nos analyses ont montré que les interrelations entre les économies de l'UEMOA en termes d'échanges commerciaux sont très limitées. Néanmoins, la synchronisation bilatérale de cycles, bien que faible, évolue depuis 2006. D'après nos estimations, en somme, nous pouvons dire que les résultats obtenus suggèrent que les déterminants clés de la synchronisation des cycles de croissance économique dans l'UEMOA sont le degré de la synchronisation de la période antérieure, les différences de structures de production, les différences d'inflation, et les chocs extérieurs communs. mots-clés : synchronisation des cycles, intégration économique, panel dynamique, GMM, UEMOA.

A model of simultaneous equations in panel data is developed to compensate for the endogeneity and simultaneity of the variables, and whose estimation is performed by the two-stage least squares techniques using instrumental variables. In addition, a composite social welfare indicator was constructed on which the impacts of migrants' transfers of funds were assessed. The results indicate that financial development is the main channel for indirect transmission of the effects of migrant transfers on economic growth. However, we did not detect a direct effect in one direction or the other between growth and transfers. Nonetheless, they have positive and very significant impacts on the welfare of the population. Also, the democratic variables introduced into the models impact positively economic growth and the standard of living in the WAEMU zone.

Our strategy is empirical. Our model is based on an accounting equation derived from the SIR model, and estimates the relationship between the growth of the daily COVID-19 confirmed cases on the one hand, and climatic variables (such as the daily average temperature and the wind speed) and governments responses to COVID-19 on the other hand. We also develop a theoretical approach to test the presence of a threshold in the effect of the temperature on the COVID-19 spread. Using a panel data on a sample of 294 territories overs 106 days (from 22 January, 2020 to 06 May, 2020), we find significant negative effect of temperature and temperature variability and significant positive effect of wind speed and precipitation on the growth of the COVID-19 confirmed cases. We also find that governments responses are associated to a lower growth of confirmed cases. But we do not find any unive...

Ils ne sont ni écrits à des fins de publication dans des revues scientifiques ni destinés à un public spécialisé, mais constituent un médium d'échange entre le monde de la recherche et le monde de la pratique. Project Reports are specifically targeted to our partners and an informed readership. They are not destined for publication in academic journals nor aimed at a specialized readership, but are rather conceived as a medium of exchange between the research and practice worlds.

The two countries are linked by very long socio-cultural and historical relationships. Beyond these affinities, their geographical proximity allows them to trade based on their economic disparities. Consequently, Nigeria's economic shocks have repercussions on Benin, in this case those of its currency. In particular, the decision of the Central Bank of Nigeria in June 2016 to let the exchange rate of the currency fluctuate freely has seriously affected the Beninese economy. This study assesses the impacts of a variation in the exchange rate between the CFA and the Naira on Benin using a computable general equilibrium (CGE) model. Thus, we were able to prospect the probable impacts of a common currency (ie a unit exchange rate) for Benin and Nigeria. Our results showed that the known decline in naira prices in June 2016 compared to 2010 had a negative and severe effect on government revenues, which declined by 19.6% for export taxes and 14.4% for internal market taxes (including imports). Similarly, the decline resulted in a sharp decline in inflation of 14% and nominal GDP of 12.4%, while real GDP rose by 2.2%. Consumption fell by 12.3% at 13.8% for rural households as against 10.9% for urban households. Thus, the depreciation of the Naira is proving to be a source of deepening inequality in Benin. This decline in Naira prices also affects employment and drives the economy towards trade and services to the detriment of productive sectors such as agriculture and industry. It penalizes unskilled workers while skilled workers take refuge in the administration. We conclude that overall, Benin is favored by a strong Naira rather than a weak Naira. In particular, a common currency scenario is not favorable for Benin.
