These are the “Enquete sur les conditions de vie des menages” (ECVM) carried out in 2003 in Burkina Faso, the “Troisieme Enquete Cameroonaise aupres des Menages” in 2007 (ECAM III) and the “Ghana Living Standard Survey” done in 2005/06 for Ghana. The “base-year” of our analyses is thus represented by the year in which the national surveys were carried out: 2003 for Burkina Faso, 2005/06 for Ghana and 2007 for Cameroon, and we made the hypothesis - strong but necessary in the absence of reliable data - that both the distribution and the level of consumption and revenues did not change between the year of the survey and the base year of our analysis. Their recent trends are highlighted and hypotheses are developed concerning the impacts of the economic crisis on those channels over the 2008-2011 period studied. Government expenditures are assumed to remain constant and the increase in government deficit, induced by the fall in domestic tax revenue and foreign aid inflows, is assumed to be compensated through increased domestic borrowing.
