This paper analyzes the possibility that some kinds of micro-companies may have market power, despite the socio-economic marginalization in which they operate. Concentrating on zones lacking infrastructure with a marginalization character, these companies are seen to have the possibility of setting prices higher than the market, acting within a framework of competition that is distinct from perfect competition. The consumer, for his part, is disposed to pay a higher price for the same good, due to the high level of costs (in terms of time and effort) that would be involved in acquiring it in more commercially-developed zones. The study is based on an analysis of 29 micro-companies, the results of which show a positive relationship between the Lerner Index and the level of marginalization in the districts where they are concentrated.

Palabras llave : market power; micro-companies; socio-economic marginalization; competition; Lerner's Index.
