最优货币区:对东亚国家的经验研究

This paper empirically examines the potential for forming an Optimal Currency Area (OCA) in selected Asian economies, including ASEAN countries, China, Japan and Korea, by testing Generalized Purchasing Power Parity (G-PPP) using Johansen’s cointegration approach. We investigate the long-term real exchange rate of six sub-groups of countries in order to find whether they share the common stochastic trend, as in an OCA, predicted by the G-PPP theory. The date set is monthly based between 1994 and 2003. We find that five sub-groups out of the six in total appear to have significant evidence of the existence of OCAs. This finding reflects the fact that those economies are actually highly integrated and interrelated to each other, and the current regional monetary arrangement (such as, the Chiang Mai Initiative (CMI)) is far lagging behind the real economic link in East Asia.     

Regional Integration in East Asia: Achievements and Future Prospects

Economic integration in East Asia has been largely market driven. Attempts in the late 1980s to establish an East Asian regional economic grouping failed to materialize for a number of reasons. The financial crisis in 1997–1998 has strengthened the realization of regional countries that they need to have some self‐help mechanisms to overcome that crisis and to prevent future crises. This led to the development of several functional integration programs, including the network of bilateral swap arrangements known as the Chiang Mai Initiative. However, progress remains slow. The question that has arisen is how far these efforts need to be supported by institutional integration. Should the ASEAN Plus Three, the main regional cooperation process in East Asia involving the 10 South‐East Asian countries plus China, Japan, and South Korea, be deepened institutionally? Meanwhile, the region has seen the establishment of a new process, the East Asia Summit, involving the above 13 countries plus Australia, India, and New Zealand. How will these different arrangements contribute to East Asia's economic dynamism and prosperity as well as peace and political stability?     

The endogeneity of the Optimum Currency Area criteria in East Asia

The Asian financial crisis in mid-1997 has increased interest in policies to achieve greater regional exchange rate stability in East Asia. It has renewed calls for greater monetary and exchange rate cooperation. A country's suitability to join a monetary union depends, inter alia, on the trade intensity and the business cycle synchronization with other potential members of the monetary union. However, these two Optimum Currency Area criteria are endogenous. Theoretically, the effect of increased trade integration (after the elimination of exchange fluctuations among the countries in the region) on the business cycle synchronization is ambiguous. Reduction in trade barriers can potentially increase industrial specialization by country and therefore resulting in more asymmetry business cycles from industry-specific shocks. On the other hand, increased trade integration may result in more highly correlated business cycles due to common demand shocks or intra-industry trade. If the second hypothesis is empirically verified, policy makers have little to worry about the region being unsynchronized in their business cycles as the business cycles will become more synchronized after the monetary union is formed. This paper assesses the dynamic relationships between trade, finance, specialization and business cycle synchronization for East Asian economies using a Generalized Method of Moments (GMM) approach. The dynamic panel approach improves on previous efforts to examine the business cycle correlations — trade link using panel procedures, which control for the potential endogeneity of all explanatory variables. Based on the findings on how trade, finance and sectoral specialization have effects on the size of common shocks among countries, potential policies that can help East Asian countries move closer toward a regional currency arrangement can be suggested. The empirical results of this study suggest that there exists scope for East Asia to form a monetary union.     

Joining Global Production Networks: Experience and Prospects of India

Cross‐border dispersion of different stages/slices of the production processes within vertically integrated global industries (“global production sharing”) has been a key structural change in the global economy in recent decades. This paper examines India's experience with exploiting opportunities created by this phenomenon for export expansion from a comparative East Asian perspective. The analysis reveals that India has so far failed fitting into global production networks in electronics and electrical goods, which have been the prime movers of export dynamism in China and the other high‐performing East Asian countries. The findings of this study provide further support to the case for completing the unfinished reform agenda, encompassing both trade and investment policy reforms, and “behind‐the‐border” reforms. There is also a strong case, based on the experiences in East Asia and elsewhere, for combining further reforms with a proactive investment promotion campaign to attract multinational enterprises engaged in global production networks.     

REFORM CREATING REGIONAL TRADE AGREEMENTS AND FOREIGN DIRECT INVESTMENT: APPLICATIONS FOR EAST ASIA

Abstract. We estimate the investment creation and diversion effects of RTAs by using an extended gravity equation focusing on domestic reform as a commitment device for RTA membership. As a case study, we estimate the impact of proposed East Asian RTAs on inward FDI. We find that: (i) reform creating RTA membership, larger market size, better skilled labour and lower trade costs all contribute positively and significantly to inward FDI; and (ii) most of the proposed East Asian RTAs promote intra‐bloc FDI. In particular, both South–North and North–North RTAs prove to be more preferable membership combinations to South–South RTAs in East Asia.     

Capital mobility,openness, and saving-investment relationship in Asia

The main objective of this paper is to investigate the relationship between openness to trade and saving-investment behaviour in Asia during the period 1990–2006. We use this relationship to examine whether those Asian countries that are more open to trade and enjoy less trade barriers have also higher degree of capital mobility. Cluster analysis is used to classify the countries into different groups according to the share of trade in their gross domestic products and their average tariff rates. The goal is to place the countries that are similar to each other in terms of their trade policy in one group. We apply the Generalized Least Square (GLS) technique to a set of balanced panel error correction models to estimate the short- and long-run relationship between saving and investment. The estimation results indicate that there exist long-run equilibrium relationships between domestic saving and investment in all groups regardless of their degree of trade openness. Moreover, contrary to Amirkhalkhali and Dar (2007) for the case of OECD, we find out that more openness in terms of trade policy is associated with higher degree of capital mobility for the case of Asian countries. One policy implication of this result for the Asian economies is that trade openness can be used as a strategy to attract capital from abroad. Our findings also confirm the prediction of new open economy macroeconomic models regarding the short- and long-run behaviour of current account.     

The prospects of a monetary union in East Asia

This paper assesses the empirical desirability of the East Asian economies to form a monetary union. The Structural Vector Autoregression (VAR) method is employed to assess the nature of macroeconomic disturbances among the East Asian countries, as a preliminary guide in identifying potential candidates for forming an Optimum Currency Area (OCA). In comparison with European countries, East Asia has less symmetric underlying structural shocks but the speed of adjustment to shocks is much faster. The empirical results suggest that there exists a scope among some small sub-regions, comprising mainly of ASEAN countries, for potential monetary integration. The finding of an increased symmetry of shocks among countries after the Asian Financial crisis indicates that the regional policy-coordinating effort after the crisis has put the region on the right track if monetary union is a desired goal.     

A SEARCH FOR CLOSER ECONOMIC RELATIONS IN EAST ASIA

In recent years, growing interdependence in East Asia through trade and financial cooperation heightened the need for East Asian Economies to engage in closer regional economic relations. This paper attempts to discuss emerging economic integration efforts in East Asia with special reference to bilateral and regional free trade agreements. It discusses backgrounds for recent developments of East Asian regionalism in terms of deepening intraregional economic dependence and financial cooperation, and South Korea's position towards FTAs with major trading partners as well as East Asian economic integration. Important issues and challenges for an East Asian FTA are presented.     

The persistence in real exchange rate: Evidence from East Asian countries

In this article, we examine the degree of persistence in monthly real exchange rate of six East Asian countries in relation to their two major trading partners, the United States and Japan, to study the validity of PPP for the 1976:01–2009:03 period. To investigate the persistency in real exchange rate series, we use sum of the autoregressive (AR) coefficients and the confidence interval for it using grid-bootstrap procedure recently developed by Hansen (1999). We have two findings: first, we find evidence for high persistency in real exchange rate in terms of the Japanese yen for five countries and for four countries in terms of the US dollar the for the full and pre-crisis sample periods. Second, for the post-crisis period, the presence of low persistency in real exchange rate supports PPP for three countries in terms of the Japanese yen and five countries in terms of the US dollar. These findings indicate that real exchange rate series of five East Asian countries are mean-revert based on their exchange rate policies and East Asian countries can form a currency union.     

FEAR OF FLOATING IN EAST ASIA?

Abstract.  We examine the de facto exchange rate arrangements in eight East Asian countries during the post-Asian crisis period. The empirical results suggest that three countries adopted a hard peg or a peg with capital account restrictions, whereas five countries moved toward a more flexible exchange rate arrangement in the post-crisis period. Three of these five countries (Korea, Indonesia and Thailand) achieved a level of exchange rate flexibility close to the level accomplished in a free floater such as Australia. These results suggest that 'fear of floating' in East Asia is not prevalent in the post-crisis period, supporting the bipolar view of the optimal exchange rate regime.     

US Credit Crisis and Spillovers to Asia

We review key highlights of the global credit crisis. We then consider how financial turmoil in the largest advanced economies might be transmitted to East Asia. The focus is on foreign trade links, international capital flows, currency market pressures and mismatches, financial sector fragilities, and countercyclical monetary and fiscal policy actions. We introduce a set of vulnerability indicators and explore whether an ordinal ranking of East Asian economies according to these vulnerability indicators seems to be related to the cross-country differences in estimated slowdowns of economic growth during the crisis. Finally, we discuss how Asian economies might encourage the adoption of a stronger regulatory and supervisory framework in the USA and whether some Asian economies and the USA might pursue a more “balanced” growth strategy after the crisis.     

International and Regional Cooperation: Asia's Role and Responsibilities

Asia has emerged from the global financial crisis as an important stabilizing force and an engine of global economic growth. The establishment of the G-20 gives Asian economies the global forum that they need to both represent their interests in global governance and deliver on responsibilities concomitant with their growing weight in the global economy. The region has a host of cooperation arrangements in APEC, ASEAN+3, and EAS (East Asian Summit), all with ASEAN as the fulcrum. They are huge assets, but they need to be repositioned to relate effectively to the G-20 process and other global arrangements. They also need to comprehend the politics of the changing structure of regional power. This paper discusses the challenges that Asia faces in aligning regional and global objectives in financial, trade, and other areas of cooperation, such as climate change and foreign investment. It argues that Asia is now a critical player in the global system and has a central contribution to make in strengthening global governance and international policy outcomes. The paper sets out ways to fill gaps in regional cooperation and link the agenda for regional cooperation more effectively to Asia's new role globally. This is essential to sustain Asia's superior growth performance, correct imbalances, and support the global economic system.     

The impact of Chinese monetary policy shocks on East and South‐East Asia1

We study the effects of Chinese monetary policy shocks on China's major trading partners in East and South‐East Asia by estimating structural vector autoregressive (SVAR) models for six economies in the region. We find that a monetary expansion in Mainland China leads to an increase in real GDP (temporary) and the price level (permanent) in a number of economies in our sample, most notably in Hong Kong and the Philippines. The impact could result from intertemporal substitution present in a general equilibrium framework, which allows for positive domestic impacts of foreign monetary expansions. Our results emphasize the growing importance of China for its neighbouring economies and the significance of Chinese shocks for the design of monetary policy in Asian economies.     

ASEAN's New Frontiers: Integrating the Newest Members into the ASEAN Economic Community

Since Vietnam, Lao People's Democratic Republic (PDR), Myanmar, and Cambodia joined the Association of Southeast Asian Nations (ASEAN) in the 1990s, concerns have been raised over a Development Divide. The real division is between ASEAN members participating in the integrated East Asian economy and those that do not. The older ASEAN members have become more efficient traders, and Cambodia, Laos, Myanmar, and Vietnam must reform faster if they are to catch up. Cambodia, Lao PDR, and Myanmar are not meeting the challenge, but Vietnam may be leaving the laggards, and the Philippines is lagging the leaders. The challenge is how to avoid a two‐tier ASEAN with fast‐growing modern economies coexisting besides inward‐looking poor countries.     

The Future of East Asia’s Trade: A Call for Better Globalization

This paper is about how East Asia should respond to the challenges of the external environment. The first challenge is the current slowdown in trade, which has been due to cyclical and structural factors such as the decline in productivity and the maturation of global value chains. The rise in protectionism as measured by rising trade restrictiveness has not impacted on trade, but political and policy uncertainty regarding the direction of trade policy seems to have begun to impact on trade growth. The policy stance of increased protectionism and a retreat from the multilateral rules‐based trading system is linked to the pockets of the population who have not seen their incomes improve and who have blamed their plight and increased inequality on globalization. In fact, the issue is more about the lack of effective responses to manage the costs of trade liberalization. East Asian economies need to respond to these challenges by upholding the multilateral rules‐based trading system, continuing the various pathways to regional economic integration, and ensuring better globalization through effective capacity building and policies to address the negative effects of trade liberalization.     

On the Exchange Rate as a Nominal Anchor: The Rise and Fall of the Credibility Hypothesis

The credibility hypothesis, which was used to support the use of a pegged exchange rate arrangement as a nominal anchor mechanism, is based on restrictive analytical foundations that circumscribe its real world applicability. While all pegged exchange rate arrangements are subject to circumstances that can undermine the sustainability of the peg, exchange rate nominal anchor pegs are especially fragile because such arrangements introduce problems that are endogenous to that particular type of regime. The East Asian crisis is used to demonstrate the fragility of exchange rate nominal anchor pegs, while the case of Australia demonstrates how a floating currency escaped the contagion of the East Asian crisis.     

A MODEL OF SELF‐FULFILLING FINANCIAL CRISES*

This paper combines the structural weakness and the self‐fulfilling panic view to explain the cause of the East Asian crises. In this model economy, the diversification strategies induce conglomerate firms to overinvest. They accumulate losses due to their unprofitable sectors and then compensate by obtaining bank loans. Domestic banks, which borrow from foreign banks, lend money as long as the total amount of accumulated loans remains within the firms’ collateral value. The model shows that if the debt to collateral value ratio belongs to a certain range a self‐fulfilling crisis can occur due to the self‐fulfilling expectations of foreign investors.     

刍议东亚概念的历史演进

＂东亚＂、＂远东＂属于外来词语,是由欧洲人最早使用的。随着历史的发展,东亚概念逐渐为其所指地理区域的国家和地区普遍接受与使用。对东亚概念形成经历的长期演变,并由此引发的学术论争进行了梳理和评价。     

Is a monetary union feasible for East Asia?

The empirical suitability of the East Asian economies for potential monetary integration is assessed. The structural vector autoregression (VAR) method is employed to identify the underlying shocks using a three-variable VAR model across the East Asian economies. The estimates of the EEC are used as a benchmark to compare the size of the underlying shocks and the speed of adjustment to shocks in both regions to determine the feasibility of forming an optimum currency area (OCA) in East Asia. The empirical results do not display strong support for forming an OCA in the East Asian region. The results do imply, however, that some small subregions are potential candidates for OCAs, since their disturbances are correlated and small and these economies adjust rapidly to shocks.     

US and East Asian Security under the Obama Presidency: A Japanese Perspective

The most important factor determining the structure of East Asia will continue to be the strategic relationship between the USA and China. It is the key component of the six party talks on the North Korean problem as well as nuclear nonproliferation. Japan is obviously a lesser strategic player, which is in a position to encourage middle-power security cooperation among the East Asian countries breathing between the USA and China. There is a conceptual, if not geopolitical, competition between Japan and China over an ideal future of East Asian regionalism, which the East Asian countries and the USA should join in a constructive manner.
