Abstract: This study aims to identify the effect of attitudes and abilities on aspirations in the entrepreneurship ecosystem. We use the sub-indices (attitudes, abilities and aspirations) of the Global Entrepreneurship Index (GEI) which measure the entrepreneurship ecosystem. The attitudes sub-index evaluate how competent individuals are to choose entrepreneurship rather than alternative occupations. The abilities sub-index measures the quality of new undertakings. The aspirations sub-index reflects the potential of start-ups to achieve internationalization, rapid growth and high productivity. Based on annual data from 2011-2018, we use a quantile regression model with fixed effects. We control for intellectual property and economic performance in addition to dummy variables that identify the particular impact on different regions. Our findings show a positive and heterogeneous effect of abilities on entrepreneurs aspirations and also a positive impact of attitudes on aspirations but only in higher quantiles. These findings contribute to the debate and are useful for formulating policies involving entrepreneurship in different countries.
