Abstract: We quantify the macroeconomic effects of the Federal Reserve’s balance sheet policy using a structural VAR combining survey-based measures of policy stance with high-frequency identification over 2009-2019. A $500 billion surprise increase in expected year-ahead Fed asset holdings lowers the 10-year Treasury yield by about 20 basis points, raises output and the price level by 0.7% and 0.3%, respectively, and reduces the unemployment rate by 0.2 percentage points. Results are robust to central bank information effects and variations in the maturity composition of Fed securities holdings, with little evidence of asymmetry between quantitative easing and quantitative tightening shocks.


Abstract: We show that the slope of the yield curve affects bank lending and economic activity through an ``expected bank profitability channel.'' Using detailed banking data and term premium shocks identified via instrumental variables or event studies, we show that a steeper yield curve---when driven by higher term premiums rather than higher expected short rates---increases bank profits and loan supply. Intuitively, a higher term premium raises the expected returns from maturity transformation---a core banking activity---thereby incentivizing bank lending. This effect is more pronounced for banks with higher leverage. We interpret these findings using a simple bank portfolio model.


Abstract: Household inflation disagreement weakens the impact of forward guidance and monetary policy shocks, especially when inflation forecasts are positively skewed. This attenuation effect is not driven by endogenous responses of inflation disagreement to contemporaneous shocks. A model with heterogeneous beliefs about the central bank’s inflation target explains these observations. Agents expecting higher future inflation perceive lower real interest rates and borrow more, constrained by borrowing limits. Increased inflation disagreement results in more borrowing-constrained agents, leading to slower aggregate consumption responses to interest rate changes. This mechanism also provides a microeconomic foundation for Euler equation discounting, helping to resolve the forward guidance puzzle.
