This wasn't that long ago, and it is probably very wise to remember that, and to learn from the past, and the lessons that experience continually offers to us. The Soviet Union collapsed -- why? The post-Soviet transition was tricky -- why? Russia has emerged under Putin into a system far from what was hopefully expected back in 92 -- why? If we do counter-factual analysis, what feasible alternative paths might have been pursued, what were the critical missteps that didn't allow that alternative path to emerge?
What do we learn from the history of communist systems in practice, and from the post-communist experience in transition for economic theory and the art of political economy?
