How to measure Political institutions quality for better assessment of economic growth dependency on the Freedom and on Democracy? Try ours’ indices.
One, who searching for assessment of Democracy quality at Polity could be discouraged by some comparisons:
|“Marker” Regimes||Regimes with the same rating|
|The Kingdom of Denmark prior to 1834, Prussia during the same period, and many other European monarchies (-10),Russian Empire and Norway prior to 1905; during the same period (-7); US-, British-, and French-occupied zones of West Germany in 1945-58 (-6); the Netherlands of the first half of the 19th century (-6 – -7)||The Chinese Empire of the early 19th century – 6; Stalinist USSR 1933-1952 -9; Maoist PR of China 1948-1975 (-8-9); Hitler’s Germany (-9)|
|“Democratic Cambodia” (Cambodia ruled by the “Khmer Rouge”) -7 – unique case of negative political competition: citizens competed for inclusion in the unique one million selected for survival (rather than the authorities or political parties competing for citizens’ support, or at least both citizens and politicians being “indifferent” to each other with zero-level competition, and so on).|
|The Russian Federation 1992 +5; 1993-99 +3||The Russian Federation 2000 – 2006 +6; 2007-2010 +4|
 As a rule, different forms of consultative estate representation were in evidence in these countries, from the local level to the state; freedom of exit, including the evidently more free countries, relative freedom of entrepreneurship and hire, relative protection for private life and property; absence of anything even remotely resembling mass repressions against potential opposition (USSR, China) or even persons potentially capable of doubting the rightness of actions undertaken by the authorities (Democratic Cambodia). In Norway (-7), a constitution thoroughly liberal by the standards of the time was in effect, and served as a model for the requirements for a liberal constitution in Denmark (Busk, Paulssen, 2007).
So, We developed simplest and better fit for comparative analysis indicators. See for details: http://ssrn.com/abstract=2495839
