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.     

Business Cycle Comovement and Labor Market Institutions: An Empirical Investigation

This paper examines the empirical link between labor market institutions and international business cycle synchronization. Using a data panel of 20 OECD countries over the 1964–2003 period, we evaluate how cross‐country labor market heterogeneity affects business cycle comovement. Our estimation strategy controls for a large set of possible factors influencing cross‐country GDP correlation, which allows a comparison of our results with those found in previous studies. We find that bilateral trade, trade similarity, monetary and fiscal convergence, as well as EMU membership lead to more synchronized cycles. Our results show that labor market regulations affect the extent of business cycle synchronization. Disparities in employment protection laws and direct taxation tend to lower international comovement while divergence in union density, unemployment benefits, and indirect taxation enhance cross‐country correlations. The level of labor market regulations also matters. Heavier employment taxes are found to raise GDP comovement.     

Bilateral Tax Treaties and GDP Comovement

Using a 30‐year panel of quarterly gross domestic product (GDP) fluctuations from of a broad set of countries, we demonstrate that the signing of a bilateral tax treaty increases the comovement of treaty partners' business cycles by half a standard deviation. This effect of fiscal policy is as large as the effect of trade linkages on comovement and stronger than the effects of several other common financial and investment linkages. We also show that bilateral tax treaties increase comovement in shocks to nations' GDP trends, demonstrating the permanent effects of coordination on fiscal policy rules. We estimate trend and business cycle components of nations' output series using an unobserved‐components model in order to measure comovement between countries and then estimate the impact of tax treaties using generalized estimating equations.     

ASIAN BUSINESS CYCLE SYNCHRONIZATION

This paper develops a multilevel structural factor model to study international output comovement and its underlying driving forces. Our method combines a structural vector autoregression with a multilevel factor model, which helps us understand the economic meaning of the estimated factors. Using quarterly data of real GDP growth covering 9 emerging Asian economies and G‐7 countries, we estimate a global supply factor, a global demand factor, and group supply and demand factors for each group of the economies. We find that although the role of the global factors has intensified over the past 15 years for most of the economies, output fluctuations in Asia have remained less synchronized with the global factor than those in the industrial countries. The Asian regional factors have become increasingly important in tightening the interdependence within the region over time. Therefore, although emerging Asian economies cannot ‘decouple’ completely from the advanced economies, they have, nonetheless, sustained a strong independent cycle among themselves. We also find that synchronized supply shocks contributed more to the observed synchronization in output fluctuations among the Asian economies than demand shocks. This points to the role of productivity enhancement and transmission of other supply shocks through, for example, vertical trade integration, rather than dependence on external demand, as the primary source of business cycle synchronization in emerging Asia.     

Dynamics of Business Cycles in Asia: Differences and Similarities

The paper documents the extent of similarities and differences of business cycle characteristics of the Asian countries and compares the cyclical regularities in this region with those of the G‐7 countries. The Asian economies are generally more volatile than the G‐7 countries, but the amplitude of economic fluctuations in the Asian countries tends to decrease over time. Comovement and persistence properties of business cycles in the Asian countries are very similar to those of the G‐7 economies. The authors find that while the patterns of business cycle fluctuations in the main macroeconomic aggregates display important similarities, the behavior of fiscal and monetary policy variables exhibits significant differences across the Asian countries. Moreover, there is a high degree of comovement between the individual country business cycles and different measures of the Asian business cycle, indicating that there is a regional business cycle specific to the Asian countries.     

BUSINESS CYCLE,CURRENCY AND TRADE,REVISITED

This paper provides long‐run historical evidence for the link between business cycle synchronization, trade and the exchange rate regime. Using data from a large number of industrialized countries and a group of Asian economies, we examine this link in three sub‐periods: the first globalization period (1870–1913), the bloc economy period (1915–1959) and the second globalization period (1960–2004). The business cycle is identified as the series of deviates from a Hodrick–Prescott filtered trend. Cyclical turning points are located in the business cycles of our sample of 21 major countries, which enables us to comment on the characteristics of business cycles in the three periods. Cross‐correlations of the cyclical deviates are calculated for all the pairs of the 21 countries examined. It is apparent from casual inspection that the business cycle characteristics and the pattern of cross‐correlations in the bloc economy period are different from those found for the two globalization periods, whereas there is less difference between the two globalization periods. Following the estimations by Frankel and Rose, we relate business cycle synchronization to trade patterns and currency unions. Consequently, we find that European integration was already discernible in terms of business cycle synchronization in the early 1900s and that a similar synchronization was not discernible for Asia.     

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.     

Does integration and economic policy coordination promote business cycle synchronization in the EU?

Previous studies have discounted important factors and indirect channels that might contribute to business cycle synchronization (BCS) in the EU. We estimate the effects of market integration and economic policy coordination on bilateral business cycle correlations over the period 1995–2012 using a simultaneous equations model that takes into accounts both the endogenous relationships and unveils direct and indirect effects. The results suggest that (1) trade and FDI have a pronounced positive effect on BCS, particularly between incumbent and new EU members. (2) Rising specialization does not decouple business cycles. (3) The decline of income disparities in EU27 contributes to BCS, as converging countries develop stronger trade and FDI linkages. (4) There is strong evidence that poor fiscal discipline of EU members is a major impediment of business cycle synchronization. (5) The same argument holds true for exchange rate fluctuations that hinder BCS, particularly in EU15. Since BCS is a fundamental prerequisite and objective in an effective monetary union, the EU has to promote market integration and strengthen the common setting of economic policies.     

Closer Economic Relations with East Asia?

This paper examines Australia's economic links with East Asia and the policy implications of these links. The main issue is whether Australia should join the regional trading arrangements with East Asian countries that have been proposed. It examines the factors which determine the share of East Asia in Australian exports. One of these, the country bias factor, is threatened by proposed regional trading arrangements which might exclude Australia. After considering the costs of exclusion, the paper concludes that Australia should consider developing new bilateral or regional trade arrangements with countries in East Asia.     

HOW DO FISCAL CONSOLIDATION AND FISCAL STIMULI IMPACT ON THE SYNCHRONIZATION OF BUSINESS CYCLES?

Using quarterly data for a panel of advanced economies, we show that synchronized fiscal consolidation (stimulus) programmes in different countries make their business cycles more closely linked. We also find: (i) some evidence of decoupling when an inflation targeting regime is unilaterally adopted; (ii) an increase in business cycle synchronization when countries fix their exchange rates and become members of a monetary union; (iii) a positive effect of bilateral trade on the synchronization of business cycles. Global factors, such as a rise in global risk aversion and uncertainty and a reversal of nonstandard expansionary monetary policy, can also reduce the degree of co‐movement of business cycles across countries. From a policy perspective, our work shows that an inflation targeting regime coupled with simultaneous fiscal consolidations can lead to more business cycle synchronization.     

Determinants of international transmission of business cycles to Turkish economy

This study aims to investigate the channels through which international business cycles are transmitted to Turkish economy. Our analysis follows two steps: i) business cycle transmission is measured using Longest Common Subsequence (LCS) method, a pattern recognition algorithm that accounts for the nonlinear and time-varying nature of business cycles and ii) the potential mechanisms of propagation of international business cycles are examined by specifying a panel regression model in which the LCS measure of synchronization is used as the dependent variable. Applying several panel estimation methods to the bilateral data from 22 countries over the 1998–2009 periods, we find that both trade and financial similarities are significant in the transmission of business cycles to Turkish economy. Especially, the results highlight the role of trade integration indicating that Turkish business cycles are closely linked with the business cycles of the members of European Custom Union.     

Is East Asia an optimum currency area?

This paper assesses the empirical desirability of the East Asian economies to an alternative exchange rate arrangement (a monetary union) that can potentially enhance the exchange rate stability and credibility in the region. Specifically, the symmetry in macroeconomic disturbances of the East Asian economies is examined as satisfying one of the preconditions for forming an Optimum Currency Area (OCA). We extend the existing literature by improving the methodology of assessing the symmetry shocks in evaluating the suitability of a common currency area in the East Asian economies employing the Bayesian State-Space Based approach. We consider a model of an economy in which the output is influenced by global, regional and country-specific shocks. The importance of a common regional shock would provide a case for a regional common currency. This model allows us to examine regional and country-specific cycles simultaneously with the world business cycle. The importance of the shocks decomposition is that studying a subset of countries can lead one to believe that observed co-movement is particular to that subset of countries when it in fact is common to a much larger group of countries. In addition, the understanding of the sources of international economic fluctuations is important for making policy decisions. The falling share of country specific factor and the rising role of region factor indicate that East Asia has become increasingly favorable for a monetary union. However, the share of country-specific factor that is still significant implies that it could be costly to renounce individual currencies to advance into a monetary union in East Asia.     

INTERNATIONAL CAPITAL FLOWS,BOOM‐BUST CYCLES,AND BUSINESS CYCLE SYNCHRONIZATION IN THE ASIA PACIFIC REGION

This article documents evidence of business cycle synchronization in selected Asia Pacific countries since the 1990s. We explain business cycle synchronization by the channel of international capital flows and boom‐bust cycles. Using the vector auto‐regression method, we find that most Asian countries experience boom‐bust cycles following capital inflows, where the boom in output is mostly driven by consumption and investment. Empirical evidence also shows that capital flow shocks are positively correlated in the region, which supports the conclusion that capital market liberalization has contributed to business cycle synchronization.

A general to specific approach for constructing composite business cycle indicators

Combining economic time series with the aim to obtain an indicator for business cycle analyses is an important issue for policy makers. In this area, econometric techniques usually rely on systems with either a small number of series, N, or, at the other extreme, a very large N. In this paper we propose tools to select the relevant business cycle indicators in a “medium” N framework, a situation that is likely to be the most frequent in empirical works. An example is provided by our empirical application, in which we study jointly the short-run co-movements of 24 European countries. We show, under not too restrictive conditions, that parsimonious single-equation models can be used to split a set of N countries in three groups. The first group comprises countries that share a synchronous common cycle, a non-synchronous common cycle is present among the countries of the second group, and the third group collects countries that exhibit idiosyncratic cycles. Moreover, we offer a method for constructing a composite coincident indicator that explicitly takes into account the existence of these various forms of short-run co-movements among variables.     

Determinants of co-movement and of lead and lag behavior of business cycles in the Eurozone

In this paper we study business cycle correlations in the Eurozone and its determinants. Additionally, we also analyze the determinants of the lead and lag behavior of business cycles in the Eurozone. We explore the relevance, in the Eurozone context, using GDP and employment as the business cycle measures, of the determinants of business cycle synchronization identified in the literature, namely bilateral trade intensity, dissimilarity of labor market rigidity, dissimilarity in industrial structures, financial openness, and foreign direct investment relations. We estimate a simultaneous 4-equations model by Ordinary Least Squares (OLS) and three-stage least square to investigate empirically the above-mentioned determinants of business cycle correlation. Bilateral trade relations present a positive influence on business cycle correlations, while the dissimilarity of labor market rigidity presents a negative influence. The rest of the above-mentioned variables are non-significant. These results are robust to the use of the Hodrick–Prescott-filter and first differences as the de-trending methods, as well as the use of GDP as the business cycle measure, excluding the financial crisis years (2008 and 2009). Results for employment as the business cycle measure are in contrast with the previous ones, and found industrial dissimilarity to be the relevant variable to determine business cycles synchronization. In what concerns the determinants of the lead and lag behavior, results show that the member states of the Eurozone that usually lead the cycle are the ones that are wealthier, with strict employment legislation, more specialized in construction and finance sectors, and more prone to international capital movements. Differences in the determinants between contemporaneous business cycles and lead and lag behavior of business cycles are especially important for policy-makers in the Eurozone to know about, in particular if asymmetric shocks between countries are set in place.     

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 Endogenity of the Optimum Currency Area Criteria

A country' suitability for entry into a currency union depends on a number of economic conditions. These include, inter alia , the intensity of trade with other potential members of the currency union, and the extent to which domestic business cycles are correlated with those of the other countries. But international trade patterns and international business cycle correlations are endogenous. This paper develops and investigates the relationship between the two phenomena. Using thirty years of data for twenty industrialised countries, we uncover a strong and striking empirical finding: countries with closer trade links tend to have more tightly correlated business cycles.

Business Cycle Synchronization in the Proposed East African Monetary Union: An Unobserved Component Approach

This paper uses the business cycle synchronization criteria of the theory of optimum currency area (OCA) to examine the feasibility of the East African Community (EAC) as a monetary union. We also investigate whether the degree of business cycle synchronization has increased after the 1999 EAC Treaty. We use an unobserved component model to measure business cycle synchronization as the proportion of structural shocks that are common across different countries, and a time‐varying parameter model to examine the dynamics of synchronization over time. We find that although the degree of synchronization has increased since 2000 when the EAC Treaty came into force, the proportion of shocks that is common across different countries is still small implying weak synchronization. This evidence casts doubt on the feasibility of a monetary union for the EAC as scheduled by 2012.     

Business Cycle Co‐movement between Australia and East Asia

This article analyses business cycle co‐movement between Australia and 10 major economies in the East‐Asian region by using two measures: concordance indices and correlation coefficients. The results from the concordance index suggest that Australia's business cycle is becoming increasingly synchronised with those in East Asia, particularly with China and Japan. The correlation coefficients of gross domestic product (GDP) growth and the deviation of real GDP from its trend between Australia and its East‐Asian neighbours are also significantly higher since 2000, relative to the correlation coefficients found for the 1990s. The growing importance of East Asia in Australia's economic future implies that the risks facing the economy have changed and Australia needs to engage in more macroeconomic policy dialogues with its neighbouring economies to improve their policy responses.
