International Capital Flows and U.S. Interest Rates

Foreign official purchases of U.S. government bonds have an economically large and statistically significant impact on long-term interest rates. Federal Reserve credibility, as evidenced by dramatic reductions in both long-term inflation expectations and the volatility of long rates, contributed much to the decline of long rates in the 1990s. More recently, however, foreign flows have become important. Controlling for various factors given by a standard macroeconomic model, we estimate that had there been no foreign official flows into U.S. government bonds over the past year, the 10-year Treasury yield would currently be 90 basis points higher. Our results are robust to a number of alternative specifications.

Foreign Participation in Local Currency Bond Markets

Countries that cannot attract foreigners to invest in their local currency bonds run the risk of currency mismatches that can result in painful crises. We analyze foreign participation in the bond markets of over 40 countries. Bond markets in less developed countries have returns characterized by high variance and negative skewness, factors that we show are eschewed by U.S. investors. While results based on a three-moment CAPM indicate that it is diversifiable idiosyncratic risk that U.S. investors shun, our analysis suggests that countries can improve foreign participation by reducing macroeconomic instability.

Home Bias and High Turnover Reconsidered

It is a stylized fact of international finance that foreign equities are underweighted (the home bias) but overtraded (the high turnover). Since stylized facts drive research, theoretical models are now developed to explain the puzzling coexistence of home bias and high turnover, first presented in Tesar and Werner (1995), and researchers now dismiss transaction costs as a plausible explanation of home bias. I show, however, that part of the puzzle - very high turnover rates on foreign equity portfolios - is based on inaccurate estimates of cross-border holdings. Revised estimates of holdings of foreign equities from comprehensive benchmark surveys produce foreign turnover rates that are much lower than previously reported and are comparable to domestic turnover rates. The implications of this finding are clear. First, researchers should no longer develop theoretical models to explain the coexistence of home bias and high turnover. Second, the relationship between transaction costs and home bias should be reexplored. On the second point, the basic intuition from Tesar and Werner (1995) - that transaction costs do not help explain the observed home bias - is confirmed using actual data on transaction costs in 41 markets.

Cross-Border Listings, Capital Controls, and Equity Flows to Emerging Markets

We investigate the impact of two types of financial liberalizations on short- and long-horizon capital flows to emerging markets in a framework that controls for push and pull factors. The first type of liberalization, a reduction in capital controls, is countrywide but uncertain, because its extent and permanence are not known with certainty. The second type, a cross-border listing, is a firm-level liberalization that has no uncertainty. Consistent with theoretical predictions, we find that the deterministic cross-listing results in an immediate but short-lived increase in capital inflows. In contrast, the uncertain reduction in capital controls results in increased inflows only over a longer horizon, if at all.

International capital flows and U.S. interest rates

Abstract Foreign purchases of U.S. government bonds have an economically large and statistically significant impact on long-term interest rates. While the dramatic reductions in both long-term inflation expectations and the volatility of long rates contributed much to the decline of long rates in the 1990s, more recently foreign flows have become important. Controlling for various factors, we estimate that absent the substantial foreign inflows into U.S. government bonds the 10-year Treasury yield would be 80 basis points higher. Our results are robust to a number of alternative specifications.

Current Account Deficits in Industrial Countries: The Bigger They are, the Harder They Fall?

There are a number of worrisome features of the U.S. current account deficit. In particular, its size and persistence, the extent to which it is financing consumption as opposed to investment, and the reliance on debt inflows raise concerns about the likelihood of a sharp adjustment. We examine episodes of current account adjustment in industrial countries to assess the validity of these concerns. Our main findings are (i) larger deficits take longer to adjust and are associated with significantly slower income growth (relative to trend) during the current account recovery than smaller deficits, (ii) consumption-driven current account deficits involve significantly larger depreciations than deficits financing investment, and (iii) there is little evidence that deficits in economies that run persistent deficits, have large net foreign debt positions, experience greater short-term capital flows, or are less open are accommodated by more extensive exchange rate adjustment or slower growth. Our findings are consistent with earlier work showing that, in general, current account adjustment tends to be associated with slow income growth and a real depreciation. Overall, our results support claims that the size of the current account deficit and the extent to which it is financing consumption matter for adjustment.

The U.S. System for Measuring Cross-Border Investment in Securities: A Primer with a Discussion of Recent Developments

The tremendous growth in cross-border securities investment in recent years has called attention to the systems used by the United States and other countries to measure international securities flows and holdings. Ideally, the data gathered by the United States could tell us the extent to which foreign investors hold U.S. securities, the types of securities held, and the countries in which the securities are held, for example, and could identify trends in investment. This article looks at how well the data shed light on these topics. Special attention is given to the systems design and the implications of the design for data analysis. Also discussed are anticipated changes to the system and international efforts to improve data collection systems worldwide.

Is Home Bias in Assets Related to Home Bias in Goods

Obstfeld and Rogoff (2000) have reinvigorated an old literature on the link between home bias in the goods market and home bias in the asset market by arguing that trade costs in the goods market can account for the observed portfolio home bias. The key link between home bias in the two markets is the real exchange rate. Home bias in consumption implies a different expenditure allocation across countries, which leads to different inflation rates when measured in the same currency. This leads investors from different countries to choose different portfolios to hedge against inflation uncertainty. An older partial equilibrium literature argued that such hedge portfolios are not large enough to produce substantial home bias. We link the general equilibrium and partial equilibrium literatures and show that in both the resulting home bias in the equity market depends on a covariance-variance ratio: the covariance between the real exchange rate and the excess return on home relative to foreign equity, divided by the variance of the excess return. Empirical evidence shows that this ratio and the implied home bias are close to zero, casting significant doubt on a meaningful link between home bias in the goods and asset markets. General equilibrium models that conclude otherwise imply a covariance-variance ratio that is at odds with the data.

The Declining Volatility Of U.S. Employment: Was Arthur Burns Right?

This paper attempts to add to the understanding of changes in the magnitude of business cycle fluctuations by examining disaggregated employment data. Specifically, we use a stochastic variance approach on monthly employment data for the 1946-1996 period to highlight two stylized facts of aggregate U.S. employment - greater volatility in recessions than expansions and reduced volatility since the early 1980s. These patterns are not, however, apparent in each sector of the economy. Asymmetric volatility is only evident in manufacturing and trade; other sectors, such as construction or the narrowly defined services sector, are just as likely to exhibit high volatility in expansions. A general reduction in volatility is evident only in goods-producing sectors; some industries in the broad service-producing sector have become more volatile over time. Our results highlight the close relationship between aggregate and manufacturing volatility, and suggest that to understand why the U.S. business cycle has become more muted, researchers should strive to understand the forces at work that are reducing volatility in the manufacturing sector.

Idiosyncratic Tastes in a Two-Country Optimizing Model: Implications of a Standard Presumption

International spillovers and exchange rate dynamics are examined in a two-country dynamic optimizing model that allows for idiosyncratic tastes across countries. Specifically, there is a home-good bias in consumption patterns: at given relative prices the ratio of home goods consumed to foreign goods consumed is higher in the home country. The setup nests Obstfeld and Rogoff (1995), who assume identical tastes. Allowing for idiosyncratic tastes produces results that differ from Obstfeld and Rogoffs expansionary monetary policy increases home utility by more, the positive spillovers of a fiscal expansion are reduced, and both short-run and long-run deviations from consumption-based purchasing power parity are possible. The models predictions are broadly consistent with those from the Frenkel, Razin and Yuen (1996) version of the two-country Mundell-Fleming model and with observed behavior of real and nominal exchange rates.
