Micro-enterprises have traditionally been considered a burden for development, from both the theoretical perspective of social sciences as well as policy praxis. However, for some years now, some of the specialized literature has presented evidence that despite their low productivity, the contribution of the informal economy to job creation and income in less-developed economies is significant. Given that other countries have begun to develop policies to encourage productivity in the informal sector, the main purpose of this paper is to understand, through a review of the regulations that support micro-enterprises, as well as new decrees and regulations, the current position of Mexico in this debate.
