Key Questions Answered

• •AI Bubble Assessment: Market valuations may justify current levels despite speculation concerns because revenue growth remains real and rapid, with customer adoption expanding significantly. Any bubble call requires prices exceeding fundamentals enough to profit from shorting today, not predicting future corrections.
• •Inflation Theory Application: Central banks possess multiple inflation frameworks but must select the correct model for each scenario. The 2020-2021 surge required quantity theory of money analysis due to nominal GDP expansion, not the New Keynesian models policymakers initially applied to interpret monetary expansion effects.
• •Fed Independence Reality: The Federal Reserve maintained operational autonomy under Biden, raising rates 75 basis points per meeting despite political pressure and delaying cuts until September 2024. Historical evidence shows independence persists even when administrations prefer accommodative policy, though future leadership composition remains uncertain.
• •Deficit-Inflation Disconnect: The federal deficit exceeds 6% of GDP without recession or emergency, yet fiscal dominance remains unlikely short-term. Current Fed composition across 12 voting members resists bailout pressure, though structural deficits combined with political constraints may eventually limit monetary policy effectiveness in controlling inflation.
