I read The Value of Everything with great interest, and am, in fact, a big fan of Mazzucato since The Entrepreneurial State. She is one of a small, but important group of economists that can restore economics as a relevant discipline in the next ten years (see).
Value theory, and the woman herself, keep resurfacing in the Internet of Humans discussion (like here and here. She is also an inspiration for the #research-network:economic-sci-fi seminar, elsewhere in Edgeryders.
I will now read the policy report, you already recommended it twice, so it must be good. And yes, do open notebook science, it’s good for the soul and for replicability.
