FEDS Working Paper: Inattentive Price Setting and Inflation Volatility Under Fiscal Policy Uncertainty

FEDS Working Paper: Inattentive Price Setting and Inflation Volatility Under Fiscal Policy Uncertainty (QuantCalc Tools Desk Note, 2026-10-28) — This briefing summarizes the supplied source material at https://www.federalreserve.gov/econres/feds/inattentive-price-setting-and-inflation-under-fiscal-policy-uncertainty.htm. Imported financial records below are historical snapshot data and have not been checked against current official registers.

Key Finding: Debt-to-GDP Ratio Drives Inflation Volatility via Firm Attention Reallocation#

Raising public debt from 100% to 175% of GDP increases inflation volatility by approximately 20% (Source: Federal Reserve FEDS Working Paper by Oliver Pfäuti and Edson Wu, Federal Reserve). The primary mechanism is firms reallocating rational attention toward fiscal shocks rather than marginal-cost signals. This result challenges the assumption that higher debt uniformly suppresses or amplifies price-setting precision — the true relationship is non-linear.

The U-Shaped Mechanism: Two Opposing Forces on Firm Attention#

The model developed by Pfäuti and Wu is defined as a rational inattention framework in which firms face uncertainty about both marginal costs and fiscal policy, and choose how much information to acquire before setting prices. Higher public debt raises steady-state taxes, which creates two opposing forces on firm attention:

1. Profit-stake dampening effect: Higher taxes reduce the profit stakes of mispricing, lowering the incentive to acquire information.
2. Tax-sensitivity amplification effect: Higher taxes make desired prices more sensitive to tax fluctuations, increasing the value of fiscal information.

The interaction of these two forces generates a U-shaped relationship between public debt and firm attention, and therefore between public debt and inflation volatility (Source: Federal Reserve FEDS Working Paper, date of publication not specified in snapshot). At intermediate debt levels, the dampening effect dominates; at high debt levels (approaching 175% of GDP), the sensitivity effect dominates, pushing inflation volatility approximately 20% higher relative to the 100%-of-GDP baseline.

Euro-Area Empirical Evidence: Debt-to-GDP and Price-Setting Passthrough#

The empirical validation uses euro-area firm-level expectations data. The passthrough of expected input-cost growth into expected selling-price growth rises systematically with a country's debt-to-GDP ratio (Source: Federal Reserve FEDS Working Paper by Oliver Pfäuti and Edson Wu, Federal Reserve). This cross-country pattern is consistent with the model's prediction that higher sovereign debt increases the weight firms place on fiscal signals when forming price expectations.

Policy Implications: Fiscal Consolidation and Inflation Stability#

The calibrated general-equilibrium model implies that fiscal consolidation — reducing debt-to-GDP ratios from elevated levels — can reduce inflation volatility by diminishing the informational salience of fiscal shocks for price-setting firms. The approximately 20% reduction in inflation volatility associated with moving from 175% to 100% of GDP in debt represents a quantitatively significant stabilization benefit beyond the conventional interest-rate channel (Source: Federal Reserve FEDS Working Paper by Oliver Pfäuti and Edson Wu, Federal Reserve). Policymakers targeting price stability should therefore account for the attention-reallocation channel when assessing the inflation consequences of sustained high public debt.

FAQ#

Q: What is the core model mechanism? The model is defined as a rational inattention general-equilibrium framework in which firms optimally choose how much information to acquire about marginal costs versus fiscal policy before setting prices. Higher public debt shifts the optimal attention allocation toward fiscal shocks, amplifying the passthrough of fiscal uncertainty into inflation volatility.

Q: What is the quantified inflation volatility impact? An increase in debt from 100% to 175% of GDP raises inflation volatility by about 20% (Source: Pfäuti & Wu, Federal Reserve FEDS Working Paper, Federal Reserve), primarily because firms reallocate attention toward fiscal shocks.

Q: What empirical data supports the model? Euro-area firm-level expectations data show that the passthrough of expected input-cost growth into expected selling-price growth rises systematically with a country's debt-to-GDP ratio, consistent with the model's predictions (Source: Pfäuti & Wu, Federal Reserve FEDS Working Paper).

Q: Why is the debt-attention relationship U-shaped rather than linear? Two opposing forces create the U-shape: higher taxes reduce mispricing profit stakes (lowering attention demand) but simultaneously make desired prices more sensitive to tax fluctuations (raising attention demand). The net effect reverses direction at intermediate debt levels, producing the U-shaped curve documented in the paper.

Q: Are the imported snapshot scores (Equilibrium 5.0/10, INTO 2.7/10) verified financial ratings? No. These scores are copied from an imported historical snapshot and have not been checked against current official regulator registers. They carry no license record in the snapshot and must not be treated as verified ratings, current authorization status, or official warnings.
