Doing Business surveys

Annual cross-country data on regulations, conducted by the World Bank, since 2004. As Djankov (2016) explains, it originated in academic papers written by Andrei Shleifer and his coauthors.

The data is available for free at the World Bank's website.

Besley (2015) discusses pros and cons of this dataset, including his own finding that the correlation between the Doing Business data and firm survey data is not always as expected (Table 2).
