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.     

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.     

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.     

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.     

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.     

The Endogeneity of Optimum Currency Areas Criteria: Some Evidence from the European Union and Portugal

Observing the statistical relationship between business cycles correlation and trade intensity in the European Union, euro zone, and the Portuguese economy, we conclude that there is, in general, a positive effect that supports the endogeneity argument proposed by Frankel and Rose (The Economic Journal 108(449):pp. 1009–1025, 1998). However, if we analyse this relationship in sub-periods – 1967–1975, 1976–1985, 1986–1992, and 1993–2003 – we conclude that endogeneity hypothesis just hold in the first two, although the correlations are increasing. This could mean that, after the Single European Act in 1986, other forces beyond trade are contributing to business cycle synchronization. The Portuguese business cycle correlation with the European Union and the Euro zone had also increased in these four decades, despite the fact that endogeneity hypothesis is at a 90 percent confidence level. We also analyse the bilateral relationships between the Portuguese economy and the other European Union countries and find that the endogeneity is confirmed in just four cases: Spain, Ireland, Netherlands, and UK.     

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.

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 in EU: A Time‐Varying Approach

This article investigates the time‐varying correlation between the EU12‐wide business cycle and the initial EU12 member‐countries based on Scalar‐BEKK and multivariate Riskmetrics model frameworks for the period 1980–2012. The paper provides evidence that changes in the business cycle synchronization correspond to major economic events that have taken place at a European level. In the main, business cycle synchronization until 2007 had moved in a direction positive for the operation of a single currency, suggesting that the common monetary policy was less costly in terms of lost flexibility at the national level. However, as a result of the Great Recession of 2007 and the subsequent Eurozone Crisis, a number of periphery countries, most notably Greece, have experienced desynchronization of their business cycles with the EU12‐wide cycle. Nevertheless, for most countries, any questions regarding the optimality and sustainability of the common currency area in Europe should not be attributed to a lack of cyclical synchronization.     

Business cycles synchronization in East Asian economy: Evidences from time-varying coherence study

This paper analyzes the feasibility of a monetary union in East Asia focusing on business cycles synchronization. Considering the critical role of trade integration in the East Asian integration process, we study whether East Asian countries are characterized by business cycle synchronization. The related empirical literature dedicated to business cycles synchronization in East Asia does not lead to firm conclusion. In this paper, we suggest a different empirical approach allowing, contrary to the previous studies, to detect endogenously structural changes in the comovement process between outputs. We apply a new measure based on the time-varying coherence function. Such a measure not only detects comovement dynamics but it distinguishes also this dynamics between short- and long-term. We compute also cohesion statistics to test if countries tend to be more synchronized or not. The main finding of this paper is that the increase in bilateral trade inside the East Asian region significantly improves long-run business cycle synchronization. The short-run influence of bilateral trade shows mixed results. Indeed, short-run cycles remain significantly influenced both by shocks hitting each country and by economic policy responses. As a consequence, more bilateral trade and convergence in economic policy constitute two complementary processes to promote business cycle synchronization.     

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.     

Trade Integration and Business Cycle Convergence: Is the Relation Robust across Time and Space?*

In this paper we investigate the relationship between trade intensity and the business cycle correlation using a panel data set taken from 24 countries over the period 1959–2003. Most previous studies did not account for the possibility that the business cycle correlation may be influenced by unobservable country‐pair specific effects. Our estimates, using both fixed‐ and random‐effects methodologies, suggest that trade intensity and the business cycle correlation are positively related to one another. However, detailed investigation shows that this relationship exists mainly for the European countries.     

Trade and business cycle synchronization in OECD countries—A re-examination

This paper re-examines the relationship between trade intensity and business cycle synchronization for 21 OECD countries in the period 1970-2003. Instead of using instrumental variables, we estimate a multivariate model including variables capturing specialization and similarity of economic policies. We confirm that trade intensity affects synchronization, but the effect is much smaller than previously reported. Other factors, like specialization and convergence in monetary and fiscal policies, have a similar impact on business cycle synchronization as trade intensity. The effect of trade on synchronization is not driven by outliers. However, the impact of trade on synchronization is not robust across deciles.     

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.     

Vertical Specialization and International Business Cycle Synchronization*

We explore the impact of vertical specialization—trade in goods across multiple stages of production—on the relationship between trade and business cycle synchronization across countries. We develop an international business cycle model in which the degree of vertical specialization varies with trade barriers. With perfect competition, we show analytically that fluctuations in measured total factor productivity are not linked across countries through trade. In numerical simulations, we find little dependence of business cycle synchronization on trade intensity. An extension of the model to allow for imperfect competition has the potential to resolve these shortcomings.     

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.     

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.     

HOW IMPORTANT ARE TERMS‐OF‐TRADE SHOCKS?

According to conventional wisdom, terms‐of‐trade shocks represent a major source of business cycles in emerging and poor countries. This view is largely based on the analysis of calibrated business‐cycle models. We argue that the view that emerges from empirical structural vector autoregression (SVAR) models is strikingly different. We estimate country‐specific SVARs using data from 38 countries and find that terms‐of‐trade shocks explain less than 10% of movements in aggregate activity. We then estimate key structural parameters of a three‐sector business‐cycle model country by country and find a disconnect between the importance assigned to terms‐of‐trade shocks by theoretical and SVAR models.     

Financial Globalization,International Business Cycles and Consumption Risk Sharing*

In spite of two decades of financial globalization, consumption‐based indicators do not seem to signal more international risk sharing. We argue that the fraction of idiosyncratic consumption risk that gets shared among industrialized countries has actually increased considerably over the period 1980–2000 and, in particular, during the 1990s—from around 30 to more than 60 percent. However, standard consumption‐based measures of risk sharing—such as the volatility of consumption conditional on output or international consumption correlations—have been unable to detect this increase because consumption has also been affected by the concurrent decline in the volatility of output growth in most industrialized countries since the 1980s. First, the volatility of output at business‐cycle frequencies has declined by more than has the volatility of permanent fluctuations. Since consumption reacts mainly to permanent shocks, it appears more volatile in relation to current changes in output. This effect seems to have offset the tendency of financial globalization to lower the volatility of consumption conditional on output. Second, because the variability of permanent global shocks has also fallen, international consumption correlations have also generally not increased as financial markets have become more integrated.     

Financial globalization and real regionalization

Over the period 1972-1986, the US business cycle was strongly correlated with the business cycle in the rest of the industrialized world. Over the period 1986-2000, international co-movement was much weaker (real regionalization). At the same time, US international asset trade has increased significantly ( financial globalization). We first document these phenomena in detail and then argue that they are related. In particular, we present a model in which financial globalization occurs endogenously in response to less correlated real shocks. Financial globalization, by enhancing cross-border capital flows, further reduces the international correlations in GDP and factor supplies. We find that both less correlated shocks and the endogenous change in international financial markets are needed to quantitatively account for the observed changes in the international business cycle.
