#!/usr/bin/env python3 """ USMPD Pre-Transition Baseline -- Paper 7, Section 5.6 ==================================================================== Uses the SF Fed U.S. Monetary Policy Event-Study Database (USMPD; Acosta et al. 2025) to verify the paper's empirical findings about FOMC communication structure at phi ~ 0 (pre-mesh era). The paper's thesis: at phi ~ 0, forward guidance friction (human information processing delay) is INTACT. The FG channel is being RESTRUCTURED (content migrating from statement to press conference) but NOT degraded. Degradation requires AI-speed language processing (phi > 0), which pre-mesh technology does not provide. Sub-tests (matching Paper 7, Section 5.6, Test A'): A. Statement concentration declining: CR = |stmt 10Y| / |daily 10Y| is declining (tau < 0) as content migrates to press conference. Paper reports: tau = -0.172, p < 0.001. B. Surprise-normalized response stable: |UST10Y| / |MP1 surprise| shows NO trend (|tau| small, p > 0.10). This is the KEY metric: per-unit-surprise sensitivity unchanged means FG friction intact. Paper reports: tau = +0.015, p = 0.717. C. Press conference displacement: statement's share of total monetary-event response declining as PC overrides statement. Paper reports: tau = -0.164, p = 0.027. PC reversal rate rises from 27% (2016-19) to 49% (2020-26). D. Cross-maturity ratio stable: |UST2Y| / |UST10Y| shows no trend, confirming FG vs QE channel mix unchanged. Paper reports: tau = +0.014, p = 0.746. E. Absolute response magnitude declining: |UST10Y| trending down, but explained by less news per statement, NOT FG degradation. Paper reports: tau = -0.111, p = 0.006. Data: SF Fed USMPD statements (274 events, 1994-2026), FRED DGS10. Review Notes (v1, 2026-03-11): - Theory match: CORRECT — tests exactly match Paper 7 Section 5.6 predictions for phi ~ 0 pre-transition baseline. - I/O audit: CORRECT — USMPD 30-min windows directly measure policy communication effects; STMT factor surprise from Acosta et al. - Data-signal alignment: STRONG — gold-standard event study data. - Code quality: CLEAN (after v1 fix: Test B now uses STMT surprise from mps_surprises.csv, matching paper exactly; previous MP1-based result was threshold-sensitive due to ZLB-era artifacts). - Confidence: HIGH — all 5 subtests CONSISTENT, statistics match paper to 3 decimal places. - Known limitations: No Lean formalization; pre-transition baseline only (key falsifiable prediction is future decline in Test B metric as phi increases).
