One big prediction…..
If the essential problem with socialist systems is calcuation, then a government owned system in which the institutions have been set up so that these calculations can be performed in a real market (and not an Oskar Lange pseudo-market) will work.
That’s the system currently in place in China, and Chinese economic reform can be seen in the context of creating a real market to resolve the socialist calculation problem in the context of public ownership. A lot of this works because there aren’t vertical command and control systems, which means that actual decisions are taking place at a lower level.
Also there is a fundamental tension between prediction and human freedom. If something is predictable than that means that you don’t have the freedom to change it, whereas if you to have the freedom to change something that renders it less predictable.
