The relevance or otherwise of the central bank's balance sheet

This paper explores the impacts on an economy of a central bank changing the size and composition of its balance sheet. One of the ways in which such asset purchases could influence prices and demand is via portfolio balance effects. We develop and calibrate a simple OLG model in which risk-averse households hold money and bonds to insure against risk. Central bank asset purchases have the potential to affect households' choices by changing the composition and return of their asset portfolios. We find that the effect is weak, and that its size depends on how fiscal policy is conducted.That is not to say that the big expansion of central bank balance sheets in recent years has been ineffective. Our finding is rather that the portfolio balance channel evaluated in an environment of normally functioning (though nonetheless incomplete) asset markets is weak. That is not inconsistent with the evidence that large-scale asset purchases by central banks since 2008 have had significant effects, because those purchases were made when financial markets were, to varying extents, dysfunctional. Nonetheless our results are relevant to those purchases because they may be unwound in an environment where financial markets are no longer dysfunctional.     

Financial super-markets: size matters for asset trade

Empirically, demand and market size effects play an important role for international trade in assets and the determination of asset prices. Financial integration decreases the cost of capital, asset prices increase with investors base and market size determines international financial flows. We present a two-country model with an endogenous number of financial assets, where the interaction of a risk diversification motive and market segmentation explains those facts. In our set up, an imperfectly competitive structure of financial markets emerges naturally and provides a new source for home bias in equity holdings. Due to co-ordination failures, the extent of financial market incompleteness is inefficiently high in equilibrium.     

Why do foreigners invest in the United States?

Why are foreigners willing to invest over $2 trillion per year in the United States? This paper tests various hypotheses and finds that standard portfolio allocation models and diversification motives are poor predictors of foreign holdings of U.S. liabilities. Instead, foreigners hold greater shares of their investment portfolios in the United States if they have less developed financial markets. The magnitude of this effect decreases with income per capita. Countries that trade more with the United States also have greater portfolio shares in U.S. equity and bond markets. These results support recent theoretical work on the role of financial development in sustaining global imbalances and have important implications for whether the United States can continue to attract sufficient financing from abroad without major changes in asset prices and returns, especially in bond markets.

What do bond holdings reveal about international funds' preferences?

International bond funds are important institutional investors in emerging markets and their asset allocation decisions have significant implications for bond market developments and debt management policies in developing countries. This paper studies emerging market bond holdings of international funds and analyzes economic and financial factors affecting their bond preferences. It shows that mutual funds prefer to invest in countries with sound fundamentals and more openness to trade. In addition, they favor bonds with high past returns and yields while averting bonds with high transaction costs and idiosyncratic risks.     

International capital flows,returns and world financial integration

International capital flows have increased dramatically since the 1980s, with much of the increase being due to trade in equity and bond markets. Such developments are often attributed to the increased integration of world financial markets. We present a model that allows us to examine how greater integration in world financial markets affects the behavior of international capital flows and financial returns. Our model predicts that international capital flows are large (in absolute value) and very volatile during the early stages of financial integration when international asset trading is concentrated in bonds. As integration progresses and households gain access to world equity markets, the size and volatility of international bond flows decline. This is the natural outcome of greater risk sharing facilitated by increased integration. This pattern is consistent with declining volatility observed during 1975–2007 period in the G-7 countries. We also find that the equilibrium flows in bonds and stocks predicted by the model are larger than their empirical counterparts, and are largely driven by variations in equity risk premia. The model also predicts that volatility of equity and bond returns decline with integration, again consistent with the data for G-7 economies.     

Can the standard international business cycle model explain the relation between trade and comovement?

Recent empirical research finds that pairs of countries with stronger trade linkages tend to have more highly correlated business cycles. We assess whether the standard international business cycle framework can replicate this intuitive result. We employ a three-country model with transportation costs. We simulate the effects of increased goods market integration under two asset market structures, complete markets and international financial autarky. Our main finding is that under both asset market structures the model can generate stronger correlations for pairs of countries that trade more, but the increased correlation falls far short of the empirical findings. Even when we control for the fact that most country-pairs are small with respect to the rest-of-the-world, the model continues to fall short. We also conduct additional simulations that allow for increased trade with the third country or increased TFP shock comovement to affect the country-pair's business cycle comovement. These simulations are helpful in highlighting channels that could narrow the gap between the empirical findings and the predictions of the model.     

Rational speculative bubbles in the gold futures market: An application of dynamic factor analysis

The existence of speculative bubbles in financial markets has been a longstanding issue under debate. Many financial economists believe that, given the assumption of rational expectations and rational behavior of economic agents, an asset should be priced according to its “market fundamentals.” Others argue that self‐fulfilling rumors of market participants can influence asset prices as well. These self‐fulfilling rumors are initiated by events extraneous to markets and are often called bubbles. The rationality of both expectations and behavior often does not imply that the price of an asset be equal to its fundamental value. In other words, there can be rational deviations of the price from this value—rational bubbles. A rational bubble can arise when the actual market price depends positively on its own expected rate of change, as normally occurs in asset markets. Since agents forming rational expectations do not make systematic prediction errors, the positive relationship between price and its expected rate of change implies a similar relationship between price and its actual rate of change. Under such conditions, the arbitrary, self‐fulfilling expectation of price changes may drive actual price changes independently of market fundamentals; we refer to such a situation as a rational price bubble.¹ © 2001 John Wiley & Sons, Inc.

China and Global Macroeconomic Interdependence

China is transitioning towards more inward‐focussed growth, causing adverse changes in the product and financial terms of trade in the advanced economies. At the same time, international financial markets tussle between tightening forces associated with the US recovery on the one hand and unconventional monetary expansion in Europe and Japan on the other. The way these shocks interact is examined in this paper using a global macromodel with national portfolio rebalancing and asset differentiation and a representation of unconventional monetary policy. Results are found to be sensitive to the contributions of productivity and capital accumulation to China's growth. When these are offered in realistic combination, the effects are deflationary in the United States and China, militating against contractionary US monetary policy. Monetary responses in the United States and China then combine with price targeting regimes in the EU and Japan to expand liquidity globally, amplifying impacts on financial markets and the global distribution of real investment.

Markets for risk and openness to trade: how are they related?

If protectionist trade policies aim to insure domestic industries against swings in world market prices, the development of financial markets could lead to trade liberalization. Likewise, trade liberalization could lead to the development of financial markets that help agents diversify the added risks. In this paper, we empirically address the hypothesis that there is a positive interdependence between financial development and liberal trade policies. We find a positive and economically significant relationship between the two, with causation running in both directions. The results are, however, somewhat dependent on the measure of trade policy being used.     

The internationalisation of the RMB: New starts,jumps and tipping points

We investigate the process of currency internationalisation of the Chinese Renminbi (RMB). Aggregated cross-border data provided by the Society for Worldwide Interbank Financial Telecommunications (SWIFT) allows better measurement of the role played by a currency in trade and settlement. RMB transactions are significant and increasing but remain concentrated in key financial centres. Analysis using an asset pricing framework shows that the footprint of Chinese corporations in international markets has at times been significant, with the size of these transactions prompting many to reassess the likely pace of RMB internationalisation and its usage as an alternate vehicle currency.     

On the connections between intra-temporal and intertemporal trades

This paper develops a new theory of international economics by introducing Heckscher–Ohlin features of intra-temporal trade into an intertemporal trade approach of current account. To do so, we consider a dynamic general equilibrium model with tradable sectors of different factor intensities, which allows for substitution between intertemporal trade (current account adjustment) and intra-temporal trade (goods trade). An economy's response to a shock generally involves a combination of a change in the composition of goods trade and a change in the current account. Flexible factor markets reduce the need for the current account to adjust. On the other hand, the more rigid the factor markets, the larger the size of current account adjustment relative to the volume of goods trade, and the slower the speed of adjustment of the current account towards its long-run equilibrium. We present empirical evidence consistent with the theory.     

Financial Integration in East Asia: An Empirical Investigation

The central objective of this paper is to empirically evaluate the degree of linkages among East Asian equity and bond markets. Using data from the IMF’s Coordinated Portfolio Investment Survey (CPIS), we find that intra‐East Asian financial asset holdings of four East Asian countries – Japan, Korea, Hong Kong and Singapore – are larger than the levels predicted by the financial gravity model. However, our analysis suggests that this result is likely to be driven by intra‐regional trade linkages and reflect those linkages. Therefore, the salient implication for regional policymakers is that they should continue to promote intra‐regional financial integration. This paper also aims to analyse the impact of three different types of country‐specific risks – political, economic and financial risks – on investment from the four countries. This analysis yields a clear positive relationship between destination‐country risk, in particular political risk, and capital inflows.     

The simultaneous evolution of economic growth,financial development,and trade openness

This article empirically investigates the interactions among economic growth, financial development, and trade openness through simultaneous equation systems. The identification and estimation of the systems rely on the methodology of identification through heteroskedasticity. The empirical results show that each of the three variables interacts in important ways. When controlling for the reverse causation, trade promotes economic growth in high-income, low-inflation, and nonagricultural countries but has a negative impact on growth in countries with the opposite attributes. Similarly, when accounting for the feedbacks from growth, banks and stock markets have different impacts on economic growth. While banking development is detrimental to output growth, stock market development is more favorable to growth in high-income, low-inflation, and nonagricultural countries. The data also reveal coexistence of a positive effect of financial development on trade and a negative effect of trade on financial development in poorer countries. In richer countries, financial development stimulates trade openness whereas trade has an ambiguous impact on financial development.     

Real and Financial Sector Interaction Under Liberalization in an Open Developing Economy

A short‐run model incorporates instantaneous portfolio equilibrium with macroeconomic flows to clarify the structure of real–financial sector interactions. If equity and foreign exchange markets are introduced in structuralist theories of asset markets in developing countries, the key result that a fall in money supply raises the rate of inflation now holds only under special conditions on partial derivatives. But there is a tendency for interest rates to rise and for fluctuations in asset prices. Fuller integration of asset markets moderates these fluctuations. Outcomes are stable in spite of the generalized complementarity distinguishing equity markets from loan markets. Expectations play a major role. Implications for policy are to link domestic interest rates to foreign, remove artificial barriers to market integration, and stimulate demand as well as supply.

Dollar illiquidity and central bank swap arrangements during the global financial crisis

While the global financial crisis was centered in the United States, it led to a surprising appreciation in the dollar, suggesting global dollar illiquidity. In response, the Federal Reserve partnered with other central banks to inject dollars into the international financial system. Empirical studies of the success of these efforts have yielded mixed results, in part because their timing is likely to be endogenous. In this paper, we examine the cross-sectional impact of these interventions. Theory consistent with dollar appreciation in the crisis suggests that their impact should be greater for countries that have greater exposure to the United States through trade and financial channels, less transparent holdings of dollar assets, and greater illiquidity difficulties. We examine these predictions for observed cross-sectional changes in CDS spreads, using a new proxy for innovations in perceived changes in sovereign risk based upon Google-search data. We find robust evidence that auctions of dollar assets by foreign central banks disproportionately benefited countries that were more exposed to the United States through either trade linkages or asset exposure. We obtain weaker results for differences in asset transparency or illiquidity. However, several of the important announcements concerning the international swap programs disproportionately benefited countries exhibiting greater asset opaqueness.     

Off the cliff and back? Credit conditions and international trade during the global financial crisis

We study the collapse of international trade flows during the global financial crisis using detailed data on monthly US imports. We show that credit conditions were an important channel through which the crisis affected trade volumes, by exploiting the variation in the cost of capital across countries and over time, as well as the variation in financial vulnerability across sectors. Countries with higher interbank rates and thus tighter credit markets exported less to the US during the peak of the crisis. This effect was especially pronounced in sectors that require extensive external financing, have limited access to trade credit, or have few collateralizable assets. Exports of financially vulnerable industries were thus more sensitive to the cost of external capital than exports of less vulnerable industries, and this sensitivity rose during the financial crisis. The quantitative implications of our estimates for trade volumes highlight the large real effects of financial crises and the potential gains from policy intervention.     

Outlook of World Economy——Sustaining the Recovery

Atier a deep global recession, economic growth has turned positive, as wide-ranging public intervention has supported demand and lowered uncertainty and systemic risk in financial markets.The recovery is expected to be slow, as financial systems remain impaired, support from public policies will gradually have to be withdrawn,and households in economics that suffered asset price busts will continue to rebuild savings while struggling with high unemployment.
