Every course here is written against a named anchor text — one standard work whose terminology and topic boundaries the course follows — and checked against a secondary witness written independently of it. Where the two disagree, the course follows the anchor and says so at the entry where the disagreement lands. These are the texts for Principles of Macroeconomics.
- Anchor
-
OpenStax, Principles of Macroeconomics 3e (Shapiro, MacDonald, Greenlaw et al.), 2022. Pinned to archive release 20260604.144757, book aff0c733-b223-4dfb-aad6-297bd361bdcf@d5cadb4, revised July 9, 2026. Restated, never reproduced.
- Secondary witness
-
University of Minnesota Libraries Publishing, Principles of Macroeconomics, 2016; adapted from a 2011 work whose publisher requested no attribution. Used for concepts rather than figures, because its data end around 2011-12.
- Research
-
The Federal Reserve Board, Bureau of Economic Analysis, Bureau of Labor Statistics, Congressional Budget Office and U.S. Treasury for the operating framework and official definitions; the World Trade Organization directly for the structure and dates of trade negotiations; and Tier 1 research for the canonical doctrines (Phillips, Friedman, Phelps).
Naming the anchor is not a claim of endorsement by its publisher, and the course is not affiliated with any of the works above. Openly licensed texts carry their licence beside them; the rest are cited, not reproduced.
