Things are really slowing down. I have responded to some comments briefly by directly reproducing the message part that required an answer. I do not agree. Contracts, legal enforcement, social responsibility, respect for law and voluntary compliance with the laws of society are some of the human institutions that we have developed.
Market makers add stability for market that are considered crucial for the economic path.
And you are quite correct that if we don't create the future deliberately, there will still be a future that we may like a lot less when we allow the laissez-faire market system to create the future. Like it or not, if we cannot communicate with the mainstream, then all our discussion will never have an impact on our profession or on policy makers in general. The mainstream talk about natural economic phenomena all the time, e.g. the natural rate of employment, etc. etc. Let us agree to recognize, at least for taxonomic purposes, a distinction between real determinates and humans. If you fudge the crispness of the taxonomy by calling human policies a real variable, you are just going to lead to semantic confusion.
