In this article we will present different theoretical views and positions on social entrepreneurship, fair trade, buying consumer behaviour and ethical consumerism. The Fair Trade, which is well recognized throughout the world, is an example of good practice of social entrepreneurship. Similarly, globalization processes, the pressure of large corporations, the rapid transmission of information, more and more developed ethical consumer behaviour is clearly contributed to both, the successful development of fair trade and social entrepreneurships. In the empirical part we reviewed and confirmed three of three sets of hypotheses through the quantitative research in Slovenia on sample of 253 respondents. Through the results of our study we also recognized the existence of opportunities for the development of social entrepreneurships in Slovenia. In the discussion and conclusion of the article listed are recommendations for further exploration of ethical consumerism, the development of social entrepreneurship and rising the profile of Fair Trade in Slovenia.
