Design without a designer.
Perhaps you’re thinking that’s not possible. Perhaps you’re imagining this post will be an anti-religious screed. No, it’s not. This is about economics, although I can’t deny that economic design without a designer applies to some other subjects.
The question remains—can a system which regulates things in a particular manner, that some might call design, not need a designer?
Adam Smith’s Invisible Hand explains the ability of the economy to provide the goods a diverse population needs. Prices get set and the right amount of each good gets produced to meet demand.
Yet there is no master in control. It happens by the individual actions of individuals and firms.
As long as they play fair.
