The Austrian Opposition to Macroeconomics

Austrian economist Friedrich von Heier calls this scientism, the slavish imitation of the methods and language of science where it is inapplicable. In macroeconomics aggregates are constructed from national accounts and mathematical relationships are sought between them. Keynes' equations attempt to predict the impact of one aggregate metric on another bear no relation to real world cause and effect because there is no way of measuring, testing and verifying any of it.
