The changing nature of the U.S. balance of payments

Earnings on cross-border investments figure only marginally in net estimates of the U.S. current account, but they represent an increasingly large share of gross flows between the United States and other nations. Because these earnings fluctuate much more sharply than trade flows, they can be expected to create permanently higher current account volatility. Such increased volatility is not necessarily grounds for concern, however; it reflects an international sharing of risk that provides a buffer against domestic economic uncertainty.Balance of payments ; International economic relations ; Investments, Foreign

Could capital gains smooth a current account rebalancing?

A narrowing of the U.S. current account deficit through exchange rate movements is likely to entail a substantial depreciation of the dollar, as stressed in the widely cited contribution by Obstfeld and Rogoff (2005). We assess how the adjustment is affected by the high degree of international financial integration in the world economy. A growing body of research stresses the increasing leverage in international financial positions, with industrialized economies holding substantial and growing financial claims on each other. Exchange rate movements then leads to valuations effects as the currency compositions of a country's assets and liabilities are not matched. In particular, a dollar depreciation generates valuation gains for the U.S. by boosting the dollar value of the large amount of its foreign-currency denominated assets. We consider an adjustment scenario in which the U.S. net external debt is held constant. The key finding is that while the current account moves into balance, the pace of adjustment is smooth. Intuitively, the valuation gains stemming from the depreciation of the dollar allow the U.S. to finance ongoing, albeit shrinking, current account deficits. We find that the smooth pattern of adjustment is robust to alternative scenarios, although the ultimate movements in exchange rates are affected.Balance of trade ; Foreign exchange rates

The International Role of the Dollar and Trade Balance Adjustment

The pattern of international trade adjustment is affected by the continuing international role of the dollar and related evidence on exchange rate pass-through into prices. This paper argues that a depreciation of the dollar would have asymmetric effects on flows between the United States and its trading partners. With low exchange rate pass-through to U.S. import prices and high exchange rate pass-through to the local prices of countries consuming U.S. exports, the effect of dollar depreciation on real trade flows is dominated by an adjustment in U.S. export quantities, which increase as U.S. goods become cheaper in the rest of the world. Real U.S. imports are affected less because U.S. prices are more insulated from exchange rate movements — pass-through is low and dollar invoicing is high. In relation to prices, the effects on the U.S. terms of trade are limited: U.S. exporters earn the same amount of dollars for each unit shipped abroad, and U.S. consumers do not encounter more expensive imports. Movements in dollar exchange rates also affect the international trade transactions of countries invoicing some of their trade in dollars, even when these countries are not transacting directly with the United States.

Self-Fulfilling Risk Panics

Recent crises have seen large spikes in asset price risk without dramatic shifts in fundamentals. We propose an explanation for these risk panics, based on selfful filling shifts in beliefs about risk, that are driven by a negative link between the current asset price and risk about the future asset price. This link implies that risk about the future asset price depends on uncertainty about future risk. This dynamic mapping of risk into itself gives rise to the possibility of multiple equilibria and can generate risk panics. In a panic, risk beliefs are coordinated around a macro fundamental that becomes a sudden focal point of the market. The magnitude of the panic is larger the weaker this macro fundamental. The sharp increase in risk leads to a large drop in the asset price, decreased leverage and reduced market liquidity. While the model is not aimed at modeling the specifics of any particular financial crisis, we show that its implications are broadly consistent with what happened during the 2007-2008 crisis.

Regulating Asset Price Risk

There has been a long debate about whether speculators are stabilizing or not. We consider a model where speculators have a stabilizing role in normal times, but may also provoke large risk panics. The very feature that makes arbitrageurs liquidity providers in normal times, namely their tolerance of risk, enables a large increase in asset price risk during a financial panic. We show that a policy that discourages balance sheet risk reduces the magnitude of financial panics, as well as asset price risk in both normal and panic states.Asset Pricing, Risk Management, Leverage.

Micro, Macro, and Strategic Forces in International Trade Invoicing

The use of different currencies in the invoicing of international trade transactions plays a major role in the international transmission of economic fluctuations. Existing studies argue that an exporter’s invoicing choice reflects structural aspects of her industry, such as market share and the price-sensitivity of demand, the hedging of marginal costs, due for instance to the use of imported inputs, and macroeconomic volatility. We use a new highly disaggregated dataset to assess the roles of the various invoicing determinants. We find support for the factors identified in the literature, and document a new feature, in the form of a link between shipments size and invoicing. Specifically, larger transactions are more likely to be invoiced in the importer’s currency. We offer a potential theoretical explanation for the empirical link between transaction size and invoicing by allowing invoicing to be set through a bargaining between exporters and importers, a feature that is absent from existing models despite its empirical relevance.

Macroeconomic Interdependence and the International Role of the Dollar

The U.S. dollar holds a dominant place in the invoicing of international trade, along two complementary dimensions. First, most U.S. exports and imports invoiced in dollars. Second, trade flows that do not involve the United States are also substantially invoiced in dollars, an aspect that has received relatively little attention. Using a simple center-periphery model, we show that the second dimension magnifies the exposure of periphery countries to the center's monetary policy, even when direct trade flows between the center and the periphery are limited. When intra-periphery trade volumes are sensitive to the center's monetary policy, the model predicts substantial welfare gains from coordinated monetary policy. Our model also shows that even though exchange rate movements are not fully efficient, flexible exchange rates are a central component of optimal policy.

International Capital Flows under Dispersed Information: Theory and Evidence

We develop a new theory of international capital flows based on dispersed information across individual investors. There is extensive evidence of information heterogeneity within and across countries, which has proven critical to understanding asset price behavior. We introduce information dispersion into an open economy dynamic general equilibrium portfolio choice model, and emphasize two implications for capital flows that are specific to the presence of dispersed information. First, gross and net capital flows become partially disconnected from publicly observed fundamentals. Second, capital flows (particularly gross flows) contain information about future fundamentals, even after controlling for current fundamentals. We find that these implications are quantitatively significant and consistent with data for industrialized countries.

The Great Retrenchment: International Capital Flows During the Global Financial Crisis

The current crisis saw an unprecedented collapse in international capital flows after years of rising financial globalization. We identify the stylized facts and main drivers of this development. The retrenchment in international capital flows is a highly heterogeneous phenomenon: first across time, being especially dramatic in the wake of the Lehman Brothers’ failure, second across types of flows, with banking flows being the hardest hit due to their sensitivity of risk perception, and third across regions, with emerging economies experiencing a shorter-lived retrenchment than developed economies. Our econometric analysis shows that the magnitude of the retrenchment in capital flows across countries is linked to the extent of international financial integration, its specific nature—with countries relying on bank flows being the hardest hit—as well as domestic macroeconomic conditions and their connection to world trade flows.
