Ok, so this paper has another proposal about how to regulate the capitalist system in order to make it stable. One question:
Are they going to get it right this time?
For the last 120 years, since the Sherman Antitrust Act, the government has been trying to fix the economy, regulate it so it won't fall apart or tear itself to pieces or whatever. And even before then it has been shoving its thumb fingers into the works with railroad grants, subsidies, inflationary monetary policies, and even wars. Every time, it has actually made more of a mess of the whole thing, making more excuses to impose even more regulation to stabilize the inherent problems in the unfettered free market system (actually, the problems the government itself caused).
So when will they get it right? When will the new regulations imposed on capitalism actually provide us the perpetually stable utopia promised?
Don't answer that. It was a rhetorical question. The answer is: Never.
An economy is too complex a thing to regulate. Not only does it involve a vast number of parts, those parts are PEOPLE, each a vastly complex entity in itself, having free will and capable of all sorts of ingenuity to evade, ignore, or even use the regulations imposed to their advantage. The result is unintended consequences, perverse incentives, the throttling of the creative powers of the best among us, often rewarding the most corrupt businessmen, causing the stagnation or instability the regulations were intended to solve.
Your clever mathematical models ("F=m(d2x/dt2") of how the economy works are just child's games compared to the real thing. They cannot model the incentives and ingenuity involved in the interactions of so many human beings.
