Abstract / Summary
- International financial integration has greatly increased the scope for changes in a country's net foreign asset position through the valuation channel, namely capital gains and losses on external assets and liabilities.
- The paper examines the valuation channel in a dynamic equilibrium portfolio model with international trade in equity.
- By separating asset prices and quantities, the authors characterize the first-order dynamics of valuation effects and the current account in macroeconomic dynamics.
- The analysis disentangles the roles of excess returns, capital gains, and portfolio adjustment for consumption risk sharing when financial markets are incomplete.

Methodology and Analytical Framework
- Framework: Dynamic equilibrium portfolio model with international trade in equity.
- Key modeling approach: Separation of asset prices and asset quantities to identify first-order dynamics.
- Focus: Interaction among excess returns, capital gains, and portfolio adjustment under financial market incompleteness.
- Outcome measures: Valuation effects on net foreign asset positions and implications for the current account and consumption risk sharing.
Key Findings
- International financial integration amplifies potential changes in net foreign asset positions via valuation (capital gains and losses).
- Valuation effects can materially affect the current account dynamics once asset price and quantity dynamics are separated.
- Excess returns, capital gains, and portfolio adjustment play distinct roles in enabling or constraining consumption risk sharing across countries when markets are incomplete.
Policy-Relevant Implications
- Monitoring valuation-driven changes in net foreign assets is essential for understanding external adjustment beyond trade flows.
- Consideration of asset price dynamics and portfolio composition is important for assessing vulnerabilities related to cross-border equity holdings.
- Policies aimed at improving consumption risk sharing should account for the limited role of portfolio adjustment under market incompleteness and the separate contributions of excess returns and capital gains.
