Functional and structural complementarities of banks and microbanks in L.D.Cs

The prime objective of this paper is to explain the concept of monetary payments as a foundation of an analytical construction of microfinance institutions (microbanks) and official banks (banks) functional complementarity's in Less Developing Countries (L.D.C's). The second objective is to show that in L.D.C's production process, part of the non spent generated income is preserved after the payment operation, in the form of deposits accounts near microbanks and banks. The share preserved near microbanks, when it is not used to finance consumer expenditure and the income generating activities, is often invested in a portfolio of deposits account near banks. Microbanks are structurally complementary to banks. They are, for this purpose, a "super deposits accounts de facto" for households which do not have access to banks financial services. From a functional point of view and taking into account their role in microfirms production cost funding, microbanks cause monetary income generation. They are "banks de facto" and are functionally complementary to banks in L.D.Cs.
