Last week, in Part I of this essay, we discussed why a central planner cannot know the right interest rate. Central planner’s macroeconomic aggregate measures like GDP are blind to the problem of capital consumption, including especially capital consumption caused by the central plan itself. GDP has an intrinsic bias towards consumption, and makes no distinction between consumption of the yield on capital, and consumption of the capital per se…between selling the golden egg, and cooking the goose that lays golden eggs.
One could quibble with this and say that, well, really, the central planners should use a different metric. This is not satisfying. It demands the retort, “if there is a better metric than GDP, then why aren’t they using it now?” GDP is, itself, supposed to be that better metric! Nominal GDP targeting is the darling central plan proposal of the Right, supposedly better than consumer price index and unemployment (as Modern Monetary Theory is the darling of the Left).
