Yuan Policy Lever Transmission Simulator Nageswaran-Srinivas Model

Quantitative balance-of-payments & industrial policy transmission workbench.
“Treating the yuan as merely a reflection of deeper distortions lets China off too easily... the exchange rate is also a policy lever in its own right.” — The Economist
Macro Policy Levers
PBOC daily central parity deviation vs equilibrium NEER.
Value-added tax (VAT) rebate & targeted energy/credit support.
Cross-border capital mobility friction (0=open, 1=closed).
Structural household consumption absorption capacity.
Foreign countervailing duties & Section 301 responses.
Transmission Results & Balance of Payments Aggressive Export Mercantilism via Dual Lever
Export Price Margin Gain +6.8% REER wedge + rebate
Current Account Surplus 4.2% Share of GDP
PBOC Monthly FX Pressure -$18.4B Intervention Outflow
Partner Import Penetration +2.1% Manufacturing Displacement
Dominant Causal Channel: Suppressed Factor Pricing & FX Fixing Wedge.
Macroeconomic Transmission Mechanism: By decoupling the yuan fixing from market balance-of-payments clears and maintaining capital restrictions (0.85), monetary authorities suppress foreign consumption import costs while domestic consumption (38.5% of GDP) fails to absorb domestic industrial capacity. The resulting trade surplus (4.2% of GDP) exerts persistent manufacturing displacement pressures across trade partners.
