Stabilization of effective exchange rates under common currency basket systems

We investigate the extent to which a common currency basket peg would stabilize effective exchange rates of East Asian currencies. We use an AMU (Asian Monetary Unit), which is a weighted average of ASEAN10 plus 3 (Japan, China, and Korea) currencies, as a common currency basket to investigate the stabilization effects. We compare our results with another result on stabilization effects of the common G3 currency (the US dollar, the Japanese yen, and the euro) basket in the East Asian countries [Williamson, J., 2005, A currency basket for East Asia, not just China. In: Policy Briefs in International Economics, No. PB05-1. Institute for International Economics]. We obtained the following results: first, the AMU peg system would be more effective in reducing fluctuations of the effective exchange rates of East Asian currencies as a number of countries applied the AMU peg system increases in East Asia. Second, the AMU peg system would more effectively stabilize the effective exchange rates than a common G3 currency basket peg system for four (Indonesia, the Philippines, South Korea, and Thailand) of the seven countries. The results suggest that the AMU peg system would be useful for the East Asian countries whose trade weights on Japan are relatively higher than others. J. Japanese Int.

从应对全球经济失衡视角看东亚经济金融合作

经常项目收支失衡加剧是全球经济失衡的重要体现。近年来,以美国为一极的发达国家经常项目逆差急剧膨胀;而包括中国在内的东亚国家和地区的经常项目顺差不断扩张。由于经常项目赤字滚雪球般地急剧膨胀,加上美国储蓄率过低、财政赤字高涨,导致了美国对国际资本的巨大需求。而东亚地区由于汇率体制和对美经济依存等原因,被动地持有大量美元资产并向美国提供大量资金。全球国际收支失衡不断向主要几个国家和地区集中,从中长期来看这种不均衡现象是不可持续的,东亚国家面临极大的风险。这一背景下,加强东亚区域经济金融合作是必然的选择。     

Crisis Vulnerability

Earlier attempts to explain the East Asian crisis of 1997 have overemphasised the importance of contagion, missing the central role of vulnerability. According to conventional accounts, Thailand experienced a financial panic due to such factors as corrupt government and corporate practices, inadequately supervised banks and venal currency speculators. Confidence in the Thai currency and banking system collapsed, provoking capital flight, a float of the Thai currency and a drastic decline in its value. This undermined confidence in the prospects of other East Asian countries, also provoking crises there. This article clarifies the concept of vulnerability and demonstrates its relevance by showing the long-term development of vulnerability in each of the three 'IMF bail-out' countries: Thailand, Indonesia and Korea. By 1996 all three were vulnerable to a currency crisis. Contagion provided the short-term trigger for the crisis but was not its underlying cause. The policy lesson is to avoid vulnerability, not to attempt to avoid contagion.     

Fear of appreciation in East and Southeast Asia: The role of the Chinese renminbi

Our study brings into light evidence of the important role of the Chinese renminbi in shaping the exchange rate behavior of a select group of East Asian currencies. Results obtained suggest that there is an additional dimension to the ‘fear of appreciation’ or ‘fear of floating-in-reverse’ behavior, initially coined by Levy-Yeyati and Sturzengger (2007) with regard to the experiences of this group of East Asian currencies. In particular, we find that there is a greater degree of aversion to appreciation of these East Asian currencies—specifically, the Philippine peso and the Thailand baht—against the Chinese renminbi than against the US dollar. This heightened fear of appreciation against the Chinese currency confirms that trade competition matters in this part of the world and that this fear to appreciate plays a central role in the exchange rate management of major East Asian currencies. As envisaged, the increasing role of China as a major trading hub in the region as well as globally, implies that the Chinese renminbi would exert a growing significant influence on other currencies in the region.     

Current account: mean-reverting or random walk behavior?

This paper sets out to investigate the statistical properties of current account in the crisis-affected countries of East Asian (Asian-5: Indonesia, Korea, Malaysia, the Philippines and Thailand) utilizing data from 1976Q1 to 2001Q4. We split the full sample period into two sub-periods of the pre-crisis (1976Q1–1996Q4) and post-crisis (1997Q1–2001Q4) eras. Univariate unit root tests indicate that current account follows a non-stationary process under both eras. However, using more sophisticated panel techniques revealed that the current account displays mean-reverting property in all three sampling periods. Meanwhile, deviations of half-life estimates in the full sample period (post-crisis) were found to be much more rapid compared to the pre-crisis period. Our major conclusions are first, the empirical evidence supports the modern intertemporal approach to current account. Second, the results reveal that the Asian-5 current accounts were on a sustainable path, even during the pre-crisis period, hence, questioning the notion that the East Asian financial crisis was due to the mismanagement of external imbalances.

Short-run and long-run effects of exchange rate change on trade balance: Evidence from China and its trading partners

As one of largest exporting countries in the world, China has experienced a large amount of trade surpluses for the past decade. However, a growing criticism has been focused on the manipulation of Chinese Yuan (RMB) exchange rate by the Chinese government. While China implemented the exchange rate reform policy in July 2005, the question, whether its currency is undervalued remains as a debatable issue. Different from previous studies by focusing on individual trading partners, this paper tests the short-run J-Curve hypothesis and long-run trade balance effect of real exchange rate between China and its eighteen major trading partners using a panel dataset over the 2005–2009 period. We adopt the methodologies of panel cointegration test, fully modified OLS for heterogeneous cointegrated panel (panel FMOLS) and panel error correction model (panel ECM) to investigate the above examination. Our empirical results lend support to the inverted J-curve hypothesis between China and its trading partners. However, we find that a real appreciation of RMB has a decreasing long-run effect on China's trade balance in only three of the eighteen trading partners, while it has an increasing long-run effect in five of the eighteen trading partners. These mixed findings, therefore, lead to the empirical evidence that the real appreciation of RMB has no overall long-run impact on China's trade balance.     

Monetary unions, external shocks and economic performance: A Latin American perspective

During the last few years there has been a renewed analysis in currency unions as a form of monetary arrangement. This new interest has been largely triggered by the Euro experience. Scholars and policy makers have asked about the optimal number of currencies in the world economy. They have analyzed whether different countries satisfy the traditional “optimal currency area” criteria. These include, among other: (a) the synchronization of the business cycle; (b) the degree of factor mobility; and (c) the extent of trade and financial integration. In this paper I analyze the desirability of a monetary union from a Latin American perspective. First, I review the existing literature on the subject. Second, I use a large data set to analyze the evidence on economic performance in currency union countries. I investigate these countries’ performance on four dimensions: (a) whether countries without a national currency have a lower occurrence of “sudden stop” episodes; (b) whether they have a lower occurrence of “current account reversal” episodes; (c) what is their ability to absorb international terms of trade shocks; and (d) what is their ability to absorb “sudden stops” and “current account reversals” shocks. I find that belonging to a currency union has not lower the probability of facing a sudden stop or a current account reversal. I also find that external shocks have been amplified in currency union countries. The degree of amplification is particularly large when compared to flexible exchange rate countries.     

The role of macroeconomic policy in rebalancing growth

The aftermath of the global financial crisis of 2007–2009 has called the export-led growth model of many Asian economies into question. This paper describes the contribution that macroeconomic policy can make to promote a rebalancing of growth away from dependence on exports to developed economies to a more sustainable pattern of growth centered on domestic and regional demand. This represents a significant departure from the traditional uses of macroeconomic policy to stabilize the economic cycle and achieve stable and low inflation. The evidence suggests that macroeconomic policy can successfully contribute to growth rebalancing. Policy measures not only can affect aggregate demand directly, but can also affect it indirectly via their “microeconomic” impacts on private sector behavior such as the household savings rate. Although in the long-term fiscal policy should be balanced to maintain government debt stability and avoid crowding out of private investment, there may be substantial scope to expand monetary and fiscal policy in the medium-term to offset the deflationary effects of an appreciating currency during periods of current account reversal. Previous experience suggests that most of the needed stimulus can be provided by monetary policy, with only a supplementary role to be played by fiscal policy. Moreover, Asian economies with large current account surpluses tend to have sufficient fiscal space.     

Global and Euro Imbalances： China and Germany

We analyze global and euro area imbalances by focusing on China and Germany as large surplus and creditor countries. In the 2000s, domestic reforms expanded the effective labor force, restrained wages, shifted income toward profits and increased corporate saving. As a result, the Chinese and German current account surpluses widened, and that of Germany has proven more persistent, with subdued domestic investment. China is an early-stage creditor, holding a short equity position and a longposition in safe debt. Germany＇s balanced net debt and equity claims mark it as a mature creditor thatprovides insurance to the rest of the world. China pays to lay off equity risk, while Germany, by contrast, harvests a moderate yield on its net claims. In both economies, the shortfall of the net international investment position from cumulated current account surpluses arises from exchange rate changes, asymmetric valuation gains, and, in Germany＇s case, credit losses.     

International monetary transmission in East Asia: Floaters,non-floaters,and capital controls

This paper analyzes the impacts of the United States (US) monetary shocks on East Asian countries using structural vector-autoregression (VAR) model. We find that the impacts of the US monetary shocks on East Asian domestic interest rates and exchange rates contradict conventional wisdom. The conventional exchange rate channel is unlikely to play much role in the transmission of the US monetary policy shocks to floaters in East Asian countries, excluding Japan. In these countries, the domestic interest rates respond strongly to the US interest rate changes, by giving up monetary autonomy, probably because of fear of floating. However, the domestic interest rate does not respond much in countries with fixed exchange rate regimes and capital account restrictions, such as China and Malaysia. This may suggest that the countries with fixed exchange rate regimes enjoy a higher degree of monetary autonomy, most likely with the help of capital account restrictions.     

Impact of RMB Appreciation on Trade and Labor Markets of China and the USA： A Multi-country Comparative General Equilibrium Model

Since the recent economic crisis, the undervaluation of China's exchange rate has been a focus in the debate on the global policy mix. Using a non‐competitive input–output table, we establish a comparative‐static general equilibrium model to simulate the impact of real exchange rate changes on Sino–US trade and labor markets. The simulation shows that the impacts of a 10‐percent RMB revaluation on the trade surplus of China and the labor market of the USA are more modest than is generally perceived, and the negative impact on the output of the non‐processing industry in China is more significant than that on the processing industry. The Sino–US trade imbalance will continue to deteriorate, China's non‐processing trade surplus will decline and the processing trade will increase, with the combined effect being small. For the USA, labor‐intensive goods imported from China will shift to different Asian countries instead of transferring back to the US market. The simulation results indicate that the impacts of an RMB revaluation on both Chinese and US labor markets would be limited.     

东亚金融一体化的动态及其收益

近年来，东亚一系列区域金融合作引起了学术界对地区金融一体化现状和收益的极大兴趣。文章基于价格和数量的测度考察了东亚地区金融一体化的程度：抛补利差和股权溢价的β收敛结果表明，危机之前东亚金融市场的全球和区域一体化并行，但在近几年，区域一体化趋势更强劲，超过了全球一体化；金融引力模型的结果表明，东亚主要的跨境金融投资者的区域内金融资产持有量比金融引力模型预测的水平更大。此外，面板回归确定了较高的金融一体化作为更广泛的金融发展的关键组成部分，会显著降低东亚国家对发达国家的经常账户失衡，因此，区域层面的金融一体化可以作为加强东亚国家的增长来源和提高经济弹性的重要政策路径。     

IS EAST ASIA FIT FOR AN OPTIMUM CURRENCY AREA? AN ASSESSMENT OF THE ECONOMIC FEASIBILITY OF A HIGHER DEGREE OF MONETARY COOPERATION IN EAST ASIA

This paper attempts to make a contribution to the recent search for a suitable assessment of the economic feasibility of a higher degree of monetary cooperation in East Asia. By using a structural vector autoregression approach as well as a generalized purchasing power parity approach, we find that a larger group of appropriately selected East Asian economies does satisfy the macroeconomic conditions for forming an Optimum Currency Area (OCA). The East Asian group consists of four ASEAN countries (Indonesia, Malaysia, Singapore, and Thailand) and four Northeast Asian economies (Hong Kong SAR, Japan, Republic of Korea, and Taiwan). This finding presents a striking contrast to the existing research results whose policy recommendation has generally been that countries in East Asia should start with a smaller subgroup currency area. It is time that many East Asian economies as a region made a serious effort to pursue a higher degree of monetary cooperation among themselves for forming an OCA.     

The evolution of renminbi yuan and the protracted debate on its undervaluation: An integrated review

For virtually a decade, the undervaluation of RMB yuan has become an issue of impassioned debate in international monetary economics. This issue kept the academic and policy circles engrossed in argumentative deliberations. That RMB yuan is undervalued is widely acknowledged. With China's emergence as an economic superpower of the future, this debate no doubt has considerable merit and ramifications. This article examines sang-froid the RMB yuan undervaluation and provides a review of recent and on-going research on it. The mid-2005 currency revaluation and modification of foreign exchange regime has enormous significance in this regard. It became a defining moment in the RMB yuan debate.This article attempts to examine whether accusations of currency manipulation made against China can hold, or are merely disingenuous. It encourages the reader to see whether the RMB yuan should be further appreciated. If yes, whether the misalignment is inordinately large or of incidental order which would be corrected with the passage of time. A good number of econometric exercises were undertaken, using differing methodologies. There was a complete lack of consensus on the misalignment of the RMB yuan. It has slowly appreciated since it abandoned its dollar peg in 2005. As the Chinese economy picks up further growth momentum, the currency appreciation is expected to accelerate.     

Real effects of common currencies in East Asia

Since the 1997 Asian currency crisis, new interest has emerged in the formation of a common currency area in East Asia. This paper provides estimates of trade and welfare effects of East Asian currency unions, using a micro-founded gravity model. Counter-factual experiments to assess the effects of various hypothetical currency arrangements for East Asia suggest that an East Asian currency union will double bilateral trade in the region, but the resulting welfare effects will be moderate. However, if Japan, a major trade partner for East Asia, is included in the union, welfare effects increase substantially. The evidence thus suggests that certain regional currency arrangements in East Asia will stimulate regional trade rigorously and can generate economically significant welfare gains.     

A tale of Asian exchange rate management: Romance of the three currencies

Asian currencies lack regional policy coordination and are therefore subject to volatilities such as the Asian currency crisis of 1997/99. As the Asian currencies have already been observed to be ‘flying-in-unison’, a stable exchange rate arrangement can be helpful as the next step of evolution for regional financial stability. We consider that creating a cluster effect from coordinated efforts/policies of policy-makers can lead to regional exchange rate stability. To demonstrate this cluster effect, a three-party-game is computed for an Asian bloc, viz-á-viz US dollar and the Euro, based on a Nash and a cooperative equilibrium. The cluster effect would generate external and internal pressures that work towards the formation of a regional currency, although the exact form of exchange rate regime would have to await political consensus. There are substantial welfare gains within Asia network economy through currency cooperation. The formation of an Asian currency bloc would also create counter-balance to the current dominance of the US dollar and the Euro. Like the epic story of Three Kingdoms who sought hegemony in Chinese history, the Asian currency bloc will contend with many possible outcomes of competition as well as cooperation.     

Policy coordination in East Asia and across the Pacific

In this paper, we construct a macro-econometric model that describes the economic activity in the Asia-Pacific area and provide quantitative insights into the recent policy debates on monetary and currency coordination among the East Asian economies. The model includes a wide variety of monetary and currency policy rules that the East Asian economies adopt and allows for one country's policymaking to have substantial effects on foreign countries. We apply the model to three current policy issues: (1) the desirability of currency basket pegs in East Asia, (2) the anticipated effects of China's currency policy reform, and (3) the non-negativity constraint on Japanese nominal interest rates. The simulation analyses show the external economy effects of policy rules quantitatively and suggest the difficulty of monetary and currency policy coordination among the East Asian economies.

Currency Substitution and the Stability of the Demand for Money in East Asia

Abstract

This paper models and tests the stability of the demand for money in five East Asian countries—Indonesia, Malaysia, Philippines, Singapore, and Thailand—in the context of an open economy. The Johansen multivariate cointegration vector error correction analysis against quarterly data covering the period 1985:1–2001:4 was used. It was found that a stationary long run cointegrating relationship exists between broad money, real income, domestic interest rates, foreign interest rates corrected for exchange rate depreciation, and the expected rate of depreciation of the exchange rate. The results show that US Treasury bills rates and the foreign exchange rate vis-à-vis the US dollar play a significant role in the East Asian countries money demand relationship. This suggests that currency substitution vis-à-vis the US dollar may be an important consideration in the design and implementation of monetary policy in the East Asian countries. Furthermore, the results show that the Asian currency crises impacted the money demand functions negatively in these countries. CUSUM and CUSUMSQ stability tests show no evidence of parameter instability of the money demand functions in three of the five countries throughout the period under investigation.
