Resumen: The objective of this research is to deepen in the role played by formal institutions on the different types of entrepreneurship (opportunity and necessity) as well as in its relative importance. The institutions we analyze are property rights, business freedom, fiscal freedom, labor freedom, financial capital and educational capital. Our results show that, in general, opportunity entrepreneurship benefits from an improvement of these institutions, while necessity entrepreneurship is damaged. This will positively influence the relative presence of opportunity entrepreneurship that is usually considered to be of greater quality and is more clearly related to economic development in a country.
