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. We examine this valuation channel in a dynamic equilibrium portfolio model with international trade in equity. By separating asset prices and quantities, we can characterize the first-order dynamics of valuation effects and the current account in macroeconomic dynamics. Specifically, we disentangle the roles of excess returns, capital gains, and portfolio adjustment for consumption risk sharing when financial markets are incomplete.

"Gross stocks of foreign assets have increased rapidly relative to national outputs since 1990, and the short-run capital gains and losses on those assets can amount to significant fractions of GDP. These fluctuations in asset values render the national income and product account measure of the current account balance increasingly inadequate as a summary of the change in a country's net foreign assets. Nonetheless, unusually large current account imbalances, especially deficits, should remain high on policymakers' list of concerns, even for the richer and less credit-constrained countries. Extreme imbalances signal the need for large and perhaps abrupt real exchange rate changes in the future, changes that might have undesired political and financial consequences given the incompleteness of domestic and international asset markets. Furthermore, of the two sources of the change in net foreign assets -- the current account and the capital gain on the net foreign asset position -- the former is better understood and more amenable to policy influence. Systematic government attempts to manipulate international asset values in order to change the net foreign asset position could have a destabilizing effect on market expectations"--NBER website

This paper highlights the increased dispersion in net external positions in recent years, particularly among industrial countries. It provides a simple accounting framework that disentangles the factors driving the accumulation of external assets and liabilities (such as trade imbalances, investment income flows, and capital gains) for major external creditors and debtors. It also examines the factors driving the foreign asset portfolio of international investors, with a special focus on the weight of U.S. liabilities in the rest of the world's stock of external assets. Finally, it relates the empirical evidence to the current debate about the roles of portfolio balance effects and exchange rate adjustment in shaping the external adjustment process.

The External Balance Assessment (EBA) methodology has been developed by the IMF’s Research Department as a successor to the CGER methodology for assessing current accounts and exchange rates in a multilaterally consistent manner. Compared to other approaches, EBA emphasizes distinguishing between the positive empirical analysis and the normative assessment of current accounts and exchange rates, and highlights the roles of policies and policy distortions. This paper provides a comprehensive description and discussion of the 2013 version (“2.0”) of the EBA methodology, including areas for its further development.

The current account deficit of the United States is more than six percent of its gross domestic product—an all-time high. And the rest of the world, including other G7 countries such as Japan and Germany, must collectively run current account surpluses to finance this deficit. How long can such unevenness between imports and exports be sustained, and what form might their eventual reconciliation take? Putting forth scenarios ranging from a gradual correction to a crash landing for the dollar, G7 Current Account Imbalances brings together economists from around the globe to consider the origins, status, and future of those disparities. An esteemed group of collaborators here examines the role of the bursting of the dot-com bubble, the history of previous episodes of current account adjustments, and the possibility of the Euro surpassing the dollar as the leading international reserve currency. Though there are areas of broad agreement—that the imbalances will ultimately decline and that currency revaluations will be part of the solution—many areas of contention remain regarding both the dangers of imbalances and the possible forms of adjustment. This volume will be of tremendous value to economists, politicians, and business leaders alike as they look to the future of the G7 economies.

This paper analyzes the seven valuation methods for unlisted direct investment equity included in the recently adopted IMF Balance of Payments and International Investment Position Manual, Sixth Edition (BPM6). Based on publicly available Danish data, we test the three methods that are generally applicable and find that the choice of valuation method and estimation technique can have a highly significant impact on the international investment position, pointing to the need for further harmonization. The results show that the price-to-book value method generates more robust market value estimates than the price-to-earnings method. This finding suggests that the valuation basis for the forthcoming Coordinated Direct Investment Survey - own funds at book value -will provide useful information for compiling the international investment position.
