Wikipedia
The ease of doing business index is an index created by the World Bank Group. Higher rankings (a low numerical value) indicate better, usually simpler, regulations for businesses and stronger protections of property rights. Empirical research funded by the World Bank to justify their work show that the economic growth impact of improving these regulations is strong.
"Empirical research is needed to establish the optimal level of business regulation—for example, what the duration of court procedures should be and what the optimal degree of social protection is. The indicators compiled in the Doing Business project allow such research to take place. Since the start of the project in November 2001, more than 800 academic papers have used one or more indicators constructed in Doing Business and the related background papers by its authors."
