The aim of this paper is to analyze the gender differences in entrepreneurial intentions by studying a range of socioeconomic and psychosocial factors. Furthermore, we aim at analyzing these differences in three groups of countries depending on the stage of economic development of each country according to the Global Competitiveness Report. Using a logistic regression analysis and data from the 2008 APS (Adult Population Survey) database which is part of the Project GEM (Global Entrepreneurship Monitor), results show the existence of gender differences in entrepreneurial intentions. The model proposed in the study has decreasing explanatory power as the degree of economic development increases, and is also more conclusive for men than women. An important methodological innovation we implemented in the current study is the use of the variable gender as a dependent variable rather than a variable of a socio demographic nature.
