Abstract: The informal economy is characterized by low productivity and does not promote diversification into higher productivity sectors. Its weight in the economy and employment in low-income countries, particularly on the African continent, makes it a priority for the international community in terms of development. Indeed, the results of the 2005 NSI Employment and Informal Sector Survey (EESI) describe a situation of widespread underemployment and computerization of 75.8 per cent and 90.4 per cent respectively.
