Essai sur le système financier: une analyse du marché du crédit en Afrique Subsaharienne

This paper aims to characterize the behavior of economic agents on Sub-Saharan Africa’s credit market in order to understand the financial exclusion of poor households. Through its theoretical approach, it gives a description of the functioning of the credit market. By considering the social interactions (social signal) as a starting point and the main determinant of the economic fact, it leads to three main results: (i) the credit supply is inversely proportional to interest rate, (ii) the need for social mobility (the pursuit of a better-being) is the main determinant of the credit demand, (iii) the financial market in Sub-Saharan Africa has three formal segments and one informal segment. Moreover, it demonstrates that in the credit market of Sub-Saharan Africa, the imbalance is the rule because only one of the four segment is in balance. Furthermore this paper notes the lack of social mobility for the poor when there is no external intervention.
