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,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.     

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.     

Business cycle synchronization and the Euro: A wavelet analysis

We use wavelet analysis to study business cycle synchronization across the EU-15 and the Euro-12 countries. Based on the wavelet transform, we propose a metric to measure and test for business cycles synchronization. Several conclusions emerge. France and Germany form the core of the Euro land, being the most synchronized countries with the rest of Europe. Portugal, Greece, Ireland and Finland do not show statistically relevant degrees of synchronization with Europe. We also show that some countries (like Spain) have a French accent, while others have a German accent (e.g., Austria). Perhaps surprisingly, we find that the French business cycle has been leading the German business cycle as well as the rest of Europe. Among the countries that may, in the future, join the Euro, the Czech Republic seems the most promising candidate.     

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.     

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.

Business Cycle Synchronization in the Enlarged EU: The Role of Bilateral Trade and FDI

The aim of this paper is to investigate the determinants of business cycle (BC) synchronization across 21 (old and new) countries of the enlarged European Union (EU). It utilizes international data to evaluate the linkages among bilateral trade in goods, bilateral foreign direct investment (FDI) flows and BC co‐movements. The paper contributes to the current literature by examining the relationship using the latest available data (sample range: 1998–2011), and thus taking into account the European sovereign debt crisis period. It also examines the role of FDI, which though increasingly important in the flows of international production factors, is currently neglected by the literature. Preliminary results show that FDI has no direct effect on BC synchronization while international trade helps to synchronize BCs but only before the recent financial crisis (pre‐2008) and only for the traditional EU countries.     

Some empirical tests on the integration of economic activity between the euro area and the accession countries

This note looks at the correlation of short‐term business cycles in the euro area and the EU accession countries. The issue is assessed with the help of vector autoregressive models. There are clear differences in the degree of correlation between accession countries. For Hungary and Slovenia, euro area shocks can explain a large share of variation in industrial production, while for some countries this influence is much smaller. For the latter countries, the results imply that joining the monetary union could entail reasonably large costs, unless their business cycles converge closer to the euro area cycle. Generally, for smaller countries the relative influence of the euro area business cycle is larger. Also, it is found that the most advanced accession countries are at least as integrated with the euro area business cycle as some small present member countries of the monetary union.

The Nature of Financial and Real Business Cycles: The Great Moderation and Banking Sector Pro‐Cyclicality

This study takes a fresh look at the nature of financial and real business cycles in OECD countries using annual data series and shorter quarterly economic indicators. It first analyses whether the last cycle has been different compared to previous cycles in terms of length, amplitude, asymmetry and changes of these parameters during expansions and contractions. We also study the degree of economic and financial cycle synchronization between OECD countries but also of economic and financial variables within a given country and gauge the extent to which cycle synchronization changed over time. We next describe the connection between the great moderation and the last cycle. Finally, the study discusses the synchronization between the real economy and the financial sector and provides some new evidence on the banking sector's pro‐cyclicality by using aggregate and bank level. The main findings show that the amplitude of the real business cycle was becoming smaller during the great moderation, but asset price cycles were becoming more volatile. In part, this was linked to developments in the banking sector which tended to accentuate pro‐cyclical behaviour. Greater synchronization of cycles may help explain the severity of the crisis.     

Business cycle synchronization and African monetary union: A wavelet analysis

In this paper, we analyze the feasibility of an African monetary union based on the necessary condition of business cycle synchronization. In this regard, we examine the synchronization of growth cycles between five Regional Economic Communities (RECs) that will have to merge to form an African monetary union: the East African Community; the Economic Community of Central African States; the Economic Community of West African States; the Southern African Development Community; and the Arab Maghreb Union. To do this, we use a new continuous wavelet approach. Results show evidence of heterogeneous synchronization across time and horizons between the RECs. Controlling for the influence of some countries' membership in several RECs at the same time, the synchronization landscape does not improve. Overall, our results suggest that business cycle synchronization across the RECs has not yet reached a sufficient level to allow African countries to benefit from a common monetary policy.     

The Endogeneity of the Optimum Currency Area Criteria, Intra-industry Trade, and EMU Enlargement

This article tests the endogeneity hypothesis of optimum currency area (OCA) criteria in a cross-section of OECD countries in the 1990s. It argues that intraindustry trade induces convergence of business cycles, while no direct relation between business cycles and bilateral trade intensity is found. This finding confirms the OCA endogeneity hypothesis, but it underlines the role of trade specialization. Furthermore, the endogeneity of OCA criteria implies a comparable degree of business cycle harmonization of Central and Eastern European countries with the EU as for the current members in the medium run.

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.     

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.     

Is productivity diverging in the EU? Evidence from 11 Member States

An argument that received a lot of attention in the political and economic discussion surrounding the recent crisis in the EU is that diverging trends in productivity across member countries will undermine the viability of the common currency. This article examines the issue of convergence in multifactor productivity using sector-level data from 11 EU Member States. A state-space model is developed, and formal Bayesian model comparisons are performed to infer whether productivity is diverging, both at the aggregate level and at a sector-by-sector basis. The data point toward diverging productivity at the aggregate level, but suggest the opposite for many individual sectors.     

Business-cycle synchronization in the EMU

This article asks whether the business cycles of the EU countries have become more or less synchronized after the introduction of the euro. Our findings show that all countries in our EU sample are better synchronized with the EMU-wide economy in the post-EMU period than they were before the euro. We also show that this increase in synchronization is present in all components of aggregate demand, as well as two supply-side variables, but it is more pronounced in the trade components (imports and, particularly, exports). It is also shown that the increase in trade within the EMU area is at least partly responsible for the increase in cyclical synchronization.     

Has the Euro changed business cycle synchronization? Evidence from the core and the periphery

Using a Bayesian dynamic factor model, I examine the comovement of output, investment and consumption growth among Euro area countries before and after the introduction of the Euro. For that purpose, I compare a pre-Euro period (1991–1998) to a Euro period (2000–2010) and identify a common Euro factor for each period separately. I find that the comovement of main macroeconomic variables and the common factor increases for core Eurozone countries from the first to the second period, while it decreases for most peripheral economies. This can be interpreted as a rise in business cycle synchronization for the core and a respective decline for the periphery. Different to the implications made by the endogeneity argument of currency areas (Frankel and Rose in Econ J 108(449):1009–1025, 1998), my evidence suggest that the introduction of the Euro has fostered imbalances between core and peripheral Eurozone countries.     

Transitional price rises with the adoption of the euro: aggregate and disaggregate sector evidence

This paper presents a time‐series regression analysis of price inflation at the time of the euro currency changeover in January 2002. Cross‐equation tests on 12 euro countries and three non‐euro EU countries are used to identify significant price changes around that time. For a small number of product and service categories, positive price changes immediately after the euro changeover suggest the possible existence of menu costs, sellers' rounding up of prices or buyers' temporary rational inattention. However, the lack of evidence for reduced inflation immediately prior to the euro changeover suggests menu costs are not important.     

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.     

UNEMPLOYMENT, HYSTERESIS AND TRANSITION

In this paper, we quantify the degree of persistence in the unemployment rates of transition countries using a variety of methods benchmarked against the EU. Initially, we work with the concept of linear ‘Hysteresis’ as described by the presence of unit roots in unemployment as in most empirical research on this area. Given that this is potentially a narrow definition, we also take into account the existence of structural breaks and nonlinear dynamics in unemployment. Finally, we examine whether CEECs' unemployment presents features of multiple equilibria, that is, if it remains locked into a new level whenever some structural change or sufficiently large shock occurs. Our findings show that, in general, we can reject the unit‐root hypothesis after controlling for structural changes and business‐cycle effects, but we can observe the presence of a high and low unemployment equilibria. The speed of adjustment is faster for CEECs than the EU, although CEECs tend to move more frequently between equilibria.     

Does One Size Fit All? A currency union with asymmetric transmissions and a stability pact

The theory of optimal currency areas stresses that a single currency zone should have symmetry across shocks and structures. What happens if the monetary transmission mechanisms differ so that a common monetary policy has different effects in different places? Using a fully specified econometric model, we find that such asymmetries are likely to destabilise the business cycle and put countries out of phase with each other in a way that cannot be corrected by deficit-constrained national fiscal policies. Market discipline, however, could achieve this. Hence, the question is whether the markets would create sufficient discipline on their own.
