Economists as Engineers of Markets?

A bit of humility is in order. Alvin E. Roth to Russ Roberts on EconTalk:

… I think that economists have to approach their role as engineers with great humility. There’s a lot we don’t understand. Economics is still an early science. But let me read you the quote from Hayek that I included in my book. This is a quote from his free-market manifesto, The Road to Serfdom. And he wrote, “There is, in particular, all the difference between deliberately creating a system within which competition will work as beneficially as possible and passively accepting institutions as they are.”

So, that was Hayek. He understood that what makes a market free is that it has rules that allow it to work freely. And one of the metaphors I use in the book is of a wheel that can rotate freely. It’s not rotating in a vacuum. It has an axle and it has well-oiled bearings. And over time–people have been designing markets for millennia. And often the process of trial and error leads to better and better markets. But it can be a lengthy process of trial and error. And as we better understand what is required for marketplaces to help markets work freely we can sometimes intervene. And, you said ‘top down,’ but earlier you talked about Uber and Airbnb. Those are marketplaces that are not top down. People have been designing marketplaces forever. It’s what we do.
