### Overview
- Authors: Ehsan U. Choudhri, Hamid Faruqee, Stephen Tokarick
- Date: December 1, 2006
- Core question: Quantify long-run welfare gains from trade liberalization versus short-run macroeconomic adjustment costs within a dynamic general equilibrium framework that integrates elements of international trade and macroeconomic models.
- Decomposition: Welfare effect = steady-state efficiency gain + transitional loss associated with wage-price stickiness.
- Key qualitative result: The transitional loss is small relative to the steady-state gain.

### Methodology
- Framework: Dynamic general equilibrium model that captures key elements of both international trade and macroeconomic models.
- Frictions considered: Wage-price stickiness driving transitional macroeconomic losses following trade liberalization.
- Exchange rate regimes analyzed: Flexible exchange rates and fixed exchange rates.
- Policy rule evaluated: Flexible price-level targeting.

### Key Findings
- Transitional loss magnitude:
  - Described as "small relative to the steady-state gain."
- Exchange rate regime comparison:
  - The transitional loss "tends to be lower under flexible as compared to fixed exchange rates."
- Policy rule effect:
  - The transitional loss "can be reduced further by a flexible price-level targeting policy rule."

### Policy Implications and Recommendations
- Exchange rate flexibility:
  - Flexible exchange rates are associated with lower transitional welfare losses following trade liberalization compared with fixed exchange rates.
- Monetary policy design:
  - Implementing a flexible price-level targeting policy rule can further reduce transitional losses from trade liberalization.
- Trade liberalization assessment:
  - Evaluate policy reforms accounting for both steady-state efficiency gains and transitional macroeconomic adjustment costs driven by wage-price stickiness.
