-Finally, I made better research. Take a look, results seems to be close to midterm between our estimates.

CIA estimates on the Soviet Union were dead wrong on the size and performance of the economy and the military burden. CIA analysts actually believed that the Soviet economy was 60 percent of the US economy and that Soviet per capita consumption was 50 percent of that of the United States. Aslund believed that these figures were too high by one- third.[44] The CIA finally began to chart lower growth rates for the Soviet economy in the mid- 1980s but by then Aslund and Aganbegyan concluded that there was zero growth in the Soviet Union between 1980 and 1986, the very years that the Carter and Reagan administration were using CIA data to justify record defense spending. The agency also failed on the crucial issue of the military burden on the economy, placing the military share of Soviet gross domestic production (GDP) between 15 and 17 percent, while some critics were arguing 25- 35&percent.
Look that Aganbegyan was one of those perestroika geniuses, could have actually underestimated the Soviet economy performance for their own purposes....If CIA estimates were inflated by one third, then the Soviet GDP would be around 1,8 trillion dollars. And if USSR was spending around 25-35% in military (which I doubt) then the reasons for collapse are quite clear. However, it must be noticed that many enterprises that produced civilian goods were part of the military industries, so USSR statistics on military expenses are not reliable

1978: USSR: 40% of USA GDP. This seems to be PPP-GDP, since Chinese "raw" GDP in 1978 is much smaller

Maddison is a major authority in long term economic growth. Always look for him...

Soviet GDP estimated in US$2trillion in 1990. Midterm between our estimates. I will take this result as being the most accurate
