Examining International Labor Organization surveys conducted in 43 countries, the finding is that the main job of just under one in three (31.5 percent) nonagricultural workers is in an informal sector enterprise. Conducting an exploratory analysis of the correlation between countries with higher levels of employment in informal sector enterprises and economic under-development (‘modernization’ thesis), higher taxes, corruption and state interference (‘neo-liberal’ thesis) and inadequate state intervention to protect workers from poverty (‘structuralist’ thesis), the finding is that there is a need to synthesize various tenets from all three perspectives. The outcome is a tentative call for a ‘neo-modernization’ perspective, which posits that higher levels of employment in informal sector enterprises are associated with economic under-development, public sector corruption and inadequate state intervention to protect workers from poverty.
