Capital Inflows and the U.S. Housing Boom

We estimate an open‐economy vector autoregressive (VAR) model to study the effect of capital‐inflow shocks on the U.S. housing market. We look at different external shocks that generate capital inflows to the U.S., in particular “saving‐glut” shocks and foreign monetary‐policy expansions. The shocks are identified with theoretically robust sign restrictions derived from an open‐economy dynamic stochastic general equilibrium (DSGE) model. Our findings suggest that capital inflows that result from “saving‐glut” shocks have a positive and persistent effect on real house prices and real residential investment.     

The Empirics of International Monetary Transmission: Identification and the Impossible Trinity

The transmission of monetary policy across borders is central to many open economy models. Research has tried to evaluate the “impossible trinity” through estimating international interest rate linkages under alternative exchange rate regimes using realized base country interest rates. Such interest rates include anticipated and endogenous elements, which need not propagate internationally. We compare international interest rate responses under pegged and non‐pegged regimes to identified, unanticipated, and exogenous U.S. interest rate changes and realized U.S. interest rate changes. We find important differences in estimated transmission from the two sets of measures—identified interest rate changes demonstrate a greater concordance with the impossible trinity than realized rate changes.     

International Transmission of U.S. Monetary Policy Shocks: Evidence from Stock Prices

This paper analyzes intraday changes in firm‐level equity prices around interest rate announcements to assess the transmission of U.S. monetary policy to the global economy. We document that foreign firms on average are roughly as sensitive to U.S. monetary policy as U.S. firms, although we also find considerable cross‐sectional variation across firms. In particular, foreign stocks in cyclically sensitive industries show stronger responses to interest rate surprises, consistent with a demand channel of policy transmission. In addition, transmission of U.S. policy appears to be stronger to economies with fixed exchange rates. Evidence for a credit channel is weaker.     

Capital Controls and the International Transmission of U.S. Money Shocks

We assess whether capital controls effectively insulate countries from U.S. monetary shocks, examining a large range of country experiences in a unified estimation framework. We estimate the effect of identified U.S. monetary shocks on the exchange rate and foreign country interest rates, and test whether countries with less open capital accounts exhibit systematically smaller responses. We find essentially no evidence of this. Other country factors such as the exchange rate regime or degree of dollarization explain more of the cross-country differences in responses. The significant differences in responses we do find are more pronounced at short horizons.     

Narrative and VAR approaches to monetary policy: Common identification problems

Romer and Romer [Romer, C.D., Romer, D.H. 1989. Does monetary policy matter? A new test in the spirit of Friedman and Schwartz. In: Blanchard, O.J., Fischer, S. (Eds.), NBER Macroeconomics Annual 1989. MIT Press, Cambridge, MA, pp. 121–170; Romer, C.D., Romer, D.H., 1994. Monetary policy matters. Journal of Monetary Economics 34, 75–88] adopted a narrative approach to address the identification problems in time series models of monetary policy. Based on Federal Reserve documents, the Romers created a dummy variable equal to one in periods when the Federal Reserve contracted in response to perceived inflationary pressures. This paper shows: (1) the dummy variable is predictable from past macroeconomic variables, reflecting the endogenous response of policy to the economy; (2) unpredictable changes in the dummy do not generate dynamic responses that look like the effects of monetary policy. The identification problems that plague time series models also afflict the narrative approach.     

Tracking U.S. inflation expectations with domestic and global indicators

Are foreign variables important for tracking U.S. inflation expectations? This paper estimates a reduced-form model that takes both domestic and global indicators of economic slack and inflationary pressures into account. Our main findings point towards the instability of the estimated parameters over the last four decades. In particular, global indicators appear to have played a statistically significant role in shaping forecasters’ expectations until the mid-1980s. By contrast, the U.S. monetary policy stance turns out to be relevant in the 1980s and 1990s. We relate this finding to the more aggressive monetary policy conduct implemented by the Fed since the end of the Volcker experiment.     

Monetary policy in emerging markets: Can liability dollarization explain contractionary devaluations?

In emerging markets, external debt is denominated almost entirely in large, developed country currencies such as the U.S. dollar. This liability dollarization offers a channel through which exchange rate variation can lead to business cycle instability. When firms' assets are denominated in domestic currency and liabilities are denominated in foreign currency, an exchange rate depreciation worsens firms' balance sheets, which leads to higher capital costs and contractions in capital spending. To illustrate this, I construct a quantitative, sticky price, small open economy model in which a monetary policy induced devaluation leads to a persistent contraction in output. In this model, fixed exchange rates offer greater stability than an interest rule that targets inflation.     

Behind the scenes of abandoning a fixed exchange rate regime

This paper explores the process of abandoning a fixed exchange rate regime during sudden stops in a small open economy. The Bank of Korea’s exchange rate policy reports during the East Asian crisis suggest that its fixed exchange rate regime was forced to collapse due to the depletion of usable foreign reserves, which resulted from the credit policy of the Korean central bank to support domestic banks in need of foreign currency liquidity. To capture the Korean crisis experience, I build a quantitative small open economy model in which, in response to the country risk premium shock, the foreign-currency credit policy of a central bank under fixed regime leads to the exhaustion of international reserves and consequent exchange rate regime shift. This model does well at replicating the observed contraction in Korean aggregate variables.     

U.S. Monetary Policy and International Bond Markets

This paper analyzes how U.S. monetary policy affects the pricing of dollar‐denominated sovereign debt. We document that yields on dollar‐denominated sovereign bonds are highly responsive to U.S. monetary policy surprises—during both the conventional and unconventional policy regimes—and that the passthrough of unconventional policy to foreign bond yields is, on balance, comparable to that of conventional policy. In addition, a conventional U.S. monetary easing (tightening) leads to a significant narrowing (widening) of credit spreads on sovereign bonds issued by countries with a speculative‐grade credit rating but has no effect on the corresponding weighted average of bilateral exchange rates for a basket of currencies from the same set of risky countries; this indicates that an unanticipated tightening of U.S. monetary policy widens credit spreads on risky sovereign debt directly through the financial channel, as opposed to indirectly through the exchange rate channel. During the unconventional policy regime, yields on both investment‐ and speculative‐grade sovereign bonds move one‐to‐one with policy‐induced fluctuations in yields on comparable U.S. Treasuries. We also examine whether the response of sovereign credit spreads to US monetary policy differs between policy easings and tightenings and find no evidence of such asymmetry.     

The impact of foreign stock markets on macroeconomic dynamics in open economies: A structural estimation

With the increased international financial integration in recent years, bilateral financial linkages between countries may have a growing influence on their real economies. This paper employs a structural two-country New Keynesian model, which incorporates a cross-border wealth channel, to estimate the effect that foreign stock market fluctuations may have on macroeconomic variables in open economy countries.The model is estimated using Bayesian methods on a sample of open economies that can potentially be affected by changes in a larger foreign stock market: Australia, Canada, New Zealand, Ireland, Austria, and the Netherlands. The estimation allows for deviations from rational expectations and for learning by economic agents.The empirical results indicate important cross-country wealth effects for Ireland and Austria, from fluctuations in the U.S. and U.K. and in the U.S. and German stock markets, respectively; the wealth effect is largest in Ireland. The data favor, instead, specifications with no significant wealth effect for the remaining countries. Foreign stock price fluctuations, however, still play a role by affecting domestic expectations about future output gaps in all countries in the sample.     

The Risk‐Taking Channel of Monetary Policy in the U.S.: Evidence from Corporate Loan Data

To study the presence of a risk‐taking channel in the U.S., we build a comprehensive data set from the syndicated corporate loan market and measure monetary policy using different measures, most notably Taylor (1993) and Romer and Romer (2004) residuals. We identify a negative relation between monetary policy rates and bank risk‐taking, especially in the run up to the 2007 financial crisis. However, this effect is purely supply‐side driven only when using Taylor residuals and an ex ante measure of bank risk‐taking. Our results highlight the sensitivity of the potency of the risk‐taking channel to the measures of monetary policy innovations.     

U.S. Monetary Regimes and Optimal Monetary Policy in the Euro Area

Monetary policy in the United States has been documented to have switched from reacting weakly to inflation fluctuations during the 1970s, to fighting inflation aggressively from the early 1980s onward. In this paper, I analyze the impact of the U.S. monetary policy regime switches on the Eurozone. I construct a New Keynesian two‐country model where foreign (U.S.) monetary policy switches regimes over time. I estimate the model for the U.S. and the Euro Area using quarterly data and find that the United States has switched between those two regimes, in line with existing evidence. I show that foreign regime switches affect home (Eurozone) inflation and output volatility and their responses to shocks, substantially, as long as the home central bank commits to a time‐invariant interest rate rule reacting to domestic conditions only. Optimal policy in the home country instead requires that the home central bank reacts strongly to domestic producer‐price inflation and to international variables, such as imported goods relative prices. In fact, I show that currency misalignments and relative prices play a crucial role in the transmission of foreign monetary policy regime switches internationally. Interestingly, I show that only marginal gains arise for the Euro Area when the European Central Bank (ECB) adjusts its policy according to the monetary regime in the United States. Thus, a simple time‐invariant monetary policy rule with a strong reaction to Producer Price Index (PPI) inflation and relative prices is enough to counteract the effects of monetary policy switches in the United States.     

美国出口管制政策、对华出口管制及其发展趋势研判

出口管制政策是美国为保障国家安全、实现外交政策所采取的经济手段之一。美国出口管制政策的原则有国家安全原则、外交政策原则和短缺物质原则等,出口管制政策的措施主要有许可证审批、商品管制清单和国别分类组等内容。影响美国对华出口管制政策未来发展的因素众多,如中国经济崛起、台海局势及美国对华巨额贸易逆差等,短期内美国不太可能放松直至取消对华出口管制政策。美国对华出口管制政策既损害了美国自身经济贸易的发展,也损害了中国经济贸易的发展,其实质是一种经济帝国主义的表现。     

The impact of exchange rate deviations from relative PPP equilibrium on the U.S. demand for foreign equities

Applying fixed-effects panel data, this study investigates the impact of U.S. dollar exchange rate movements during different exchange rate states (overvaluation and undervaluation) on the monthly real gross and real net purchases of foreign equities by U.S. residents over the post-Plaza Accord period. The foreign equities come from 22 developed and 25 developing countries. Previous research has posited two alternative hypotheses regarding the relationship between exchange rates and foreign investment. These are the wealth effect and the profit-oriented effect. The evidence herein suggests that these two hypotheses coexist. We find robust evidence for a negative relationship between the exchange rate movements of an undervalued U.S. dollar and the demand for foreign equities. For developed countries, the wealth effect dominates the profit-oriented effect when the U.S. dollar is overvalued, while, for developing countries, the profit-oriented effect dominates the wealth effect. The results emphasize the importance of considering exchange rate states derived from a relative PPP equilibrium when analyzing U.S. allocations to foreign equities. The findings with respect to the macroeconomic control variables are mainly in agreement with the predictions of international financial theory. Some of the results, however, disappear or become inconclusive for the period after the bankruptcy of Lehman Brothers. This may be explained by the increased uncertainty in international financial markets following this unprecedented event. The findings are robust with respect to different constructed equilibrium exchange rates.     

International Transmission Channels of U.S. Quantitative Easing: Evidence from Canada

The U.S. Federal Reserve responded to the great recession by implementing quantitative easing, or large‐scale asset purchases, when its conventional policy rate reached the zero lower bound. We assess the international spillover effects of this quantitative easing program on the Canadian economy in a factor‐augmented vector autoregression (FAVAR) framework, by considering a counterfactual scenario in which the Federal Reserve's long‐term asset holdings do not rise in response to the recession. We find that U.S. quantitative easing boosted Canadian output, mainly through the financial channel.     

Hot Money and Quantitative Easing: The Spillover Effects of U.S. Monetary Policy on the Chinese Economy

We develop a factor‐augmented vector autoregression (FA‐VAR) model to estimate the effects that unanticipated changes in U.S. monetary policy and economic policy uncertainty have on the Chinese housing, equity, and loan markets. We find the decline in the U.S. policy rate since the Great Recession has led to a significant increase in Chinese housing investment. One possible reason for this effect is the substantial increase in the inflow of “hot money” into China. The responses of Chinese variables to U.S. shocks at the zero lower bound are different from those responses in normal times.     

The U.S. current account deficit and the expected share of world output

We investigate the possibility that the large current account deficits of the U.S. are the outcome of optimizing behavior. We develop a simple long-run world equilibrium model in which the current account is determined by the expected discounted present value of its future share of world GDP relative to its current share of world GDP. The model suggests that under some reasonable assumptions about future U.S. GDP growth relative to the rest of the advanced countries—more modest than the growth over the past 20 years—the current account deficit is near optimal levels. We then explore the implications for the real exchange rate. Under some plausible assumptions, the model implies little change in the real exchange rate over the adjustment path, though the conclusion is sensitive to assumptions about tastes and technology. Then we turn to empirical evidence. A test of current account sustainability suggests that the U.S. is not keeping on a long-run sustainable path. A direct test of our model finds that the dynamics of the U.S. current account—the increasing deficits over the past decade—are difficult to explain under a particular statistical model (Markov-switching) of expectations of future U.S. growth. But, if we use survey data on forecasted GDP growth in the G-7, our very simple model appears to explain the evolution of the U.S. current account remarkably well. We conclude that expectations of robust performance of the U.S. economy relative to the rest of the advanced countries is a contender—though not the only legitimate contender—for explaining the U.S. current account deficit.     

Uncovered Equity Parity and rebalancing in international portfolios

Portfolio rebalancing is a key driver of the Uncovered Equity Parity (UEP) condition. According to UEP, when foreign equity holdings outperform domestic holdings, domestic investors are exposed to higher exchange rate exposure and hence repatriate some of the foreign equity to decrease their exchange rate risk. By doing so, foreign currency is sold, leading to foreign currency depreciation. We examine the relationship between U.S. investors' portfolio reallocations and returns and find some evidence consistent with UEP: Portfolio shifts are related to past returns in the underlying equity markets. But we argue that a motive other than reducing currency risk exposure is likely behind this rebalancing. In particular, U.S. investors rebalance away from equity markets that recently performed well and move into equity markets just prior to relatively strong performance, suggesting tactical reallocations to increase returns rather than reduce risk.     

Oil Currency and the Dollar Standard: A Simple Analytical Model of an International Trade Currency

The U.S. dollar is the central reference currency for international trade pricing and the main invoicing currency for primary commodities. This paper links these two observations within a stylized theoretical framework, and shows how to obtain a quantitative estimate of the gain to the U.S. economy when the dollar is a reference currency. With dollar invoicing of primary commodities, U.S. firms bear less exchange rate risk than foreign firms. This asymmetry leads to a dollar standard in international goods pricing. We then derive a simple analytical formula to calculate the gains and find that they are extremely small.     

External shocks, U.S. monetary policy and macroeconomic fluctuations in emerging markets

Estimated structural VARs show that external shocks are an important source of macroeconomic fluctuations in emerging markets. Furthermore, U.S. monetary policy shocks affect interest rates and the exchange rate in a typical emerging market quickly and strongly. The price level and real output in a typical emerging market respond to U.S. monetary policy shocks by more than the price level and real output in the U.S. itself. These findings are consistent with the idea that “when the U.S. sneezes, emerging markets catch a cold.” At the same time, U.S. monetary policy shocks are not important for emerging markets relative to other kinds of external shocks.
