The indices vary between 0 and 1, higher values corresponding to more market restrictions by the government. This database is a result of an extensive work on collecting and processing of the original (non-revised) legal texts. It covers 64 countries from all continents between 1910 and 2018. All data are available free of charge.
This database benefitted from the kind contribution of many people.
