figure 1: Log M2 divided by real GDP (blue), log GDP deflator (tan), both Q1 2000 = 0. Recession peak-to-trough dates as defined by NBER are grayed out. Sources: BEA, Federal Reserve via FRED, NBER, and authors’ calculations.
figure 2: Nominal GDP divided by M2 (blue), expressed logarithmically. Recession peak-to-trough dates as defined by NBER are grayed out. Sources: BEA, Federal Reserve via FRED, NBER, and authors’ calculations.
