Measuring Open Access Orders

This paper assesses how to quantitatively classify countries as conforming to the ideal of an “open access order” in the spirit of Douglass North, John Joseph Wallis, and Barry Weingast’s Violence and Social Orders. It does so by taking the harmonic mean of already existing measures of economic freedom, liberal democracy, and state capacity. Thirty-five countries out of 161 in 2020 were assessed to be open access orders. A main dataset is constructed for the years 1950 to present, and a supplementary dataset for select countries is constructed for years back to 1850. Switzerland has the highest index score for open access orders in 2020, is classified to be an open access order continuously since 1950, and is the first country to be classified as an open access order (in 1875). A naïve descriptive application of the historical data suggests that about three-quarters of the world will be an open access in the steady state, should postwar worldwide trends persist indefinitely
