The third dimension of three-dimensional economics, change, suggests that studying economics also means studying history. The process of change in society cannot be understood without considering the past and how it changed, eventually becoming the present.

Writers after Coase have referred to the authority structure of the firm as a "visible hand" that works in combination with Smith's invisible hand. The everyday fact that employers exercise power over their employees — not news to most employees — had been a central theme in Marx's economics, but it was (and generally continues to be) overlooked by most neoclassical economists.
