In 1990s the following statement was quite popular (roughly): "Economics of the USSR did not work, because there were shortages of goods, incorrect prices and no theory apart from Marxism".
However, I think that there are some analogies between pieces of western economics theory and economics of the former USSR. Which of western economic theories (that had worked in the USSR) would you like to stress? I will present some of my ideas and expect others to express their opinion.
