The Value of Everything: Making and Taking in the Global Economy

by Mariana Mazzucato

In essence, we behave as economic actors according to the vision of the world of those who devise the accounting conventions. The marginalist theory of value underlying contemporary national accounting systems leads to an indiscriminate attribution of productivity to anyone grabbing a large income, and downplays the productivity of the less fortunate. In so doing, it justifies excessive inequalities of income and wealth and turns value extraction into value creation. Put bluntly, any activity that can be exchanged for a price counts as adding to GDP. The accountants determine what falls into this category. But what criteria do they use? The answer is a hodge-podge which combines marginal utility with statistical feasibility and some sort of common sense that invites lobbying rather than reasoning about value.
