The Money Illusion, authored by economist Scott Sumner, stands as one of the most influential economics blogs of the past two decades. Sumner's persistent advocacy for nominal GDP targeting helped reshape monetary policy discussions during and after the 2008 financial crisis, earning him recognition as a key figure in the 'market monetarist' movement. The blog excels at making complex monetary economics accessible while maintaining academic rigor. Posts thoughtfully challenge conventional wisdom on inflation, central banking, and macroeconomic policy. While the finance applications are somewhat narrower"focused primarily on monetary policy implications rather than practical investment advice"the insights remain valuable for understanding market dynamics. Essential reading for anyone serious about monetary economics.
