By addressing social issues, rather than maximizing profits, social enterprises are said to contribute to the well-being of societies. In this paper, we test whether social enterprises fulfil this expectation. The paper applies regression analysis to a unique dataset obtained by merging survey data from the Global Entrepreneurship Monitor with official statistics on social enterprises in Luxembourg. Results suggest that social enterprises contribute to subjective well-being, which is an encompassing measure of people’s satisfaction with their own life. We find that (...) when the share of social enterprises in a city increases, the ill-being of poor and unemployed people declines. Therefore, policy makers who seek to increase the well-being of economically disadvantaged people could adopt policies to promote the creation of social enterprises. (shrink)
