similarities and convergence in g 7 cycles this paper examines the properties of g 7 cycles using a multicountry bayesian panel var model with time variations unit specific dynamics and cross country interdependences we demonstrate the presence of a significant world cycle and show that country specific indicators play a much smaller role we detect di erences across business cycle phases but apart from an increase in synchronicity in the late 1990s find little evidence of major structural changes we also find no evidence of the existence of an euro area specific cycle or of its emergence in the 1990s

u s and canadian industrial production indices as coupled oscillators abstract this paper uses ozaki s 1985 variable amplitude coefficient model to explore the impact of different types of dynamical linkages coupling between the indices of industrial production for the u s and canada empirical analysis reveals that for each country the requisite lag structure extends for up to six years and that the coupling linkages are functions of lagged changes in growth rates incorporating these linkages leads to an increased degree of oscillation in the equilibrium paths a marginal improvement in stability and somewhat greater synchronization between the two series the out of sample forecasts for each series are improved by the coupling

conditional asymmetries in real gnp a seminonparametric approach two critical assumptions are often made in empirical research regarding the relationship between economic variables and economic disturbances linearity and gaussianity together these two assumptions place strong restrictions on the time series behavior of a model most important these restrictions imply conditional symmetry using seminonparametric snp techniques this article presents evidence that real gross national product growth displays conditional asymmetry although these results confirm related results of brock and sayers sichel and hamilton the snp approach is novel in that it emphasizes the relationship between common modeling assumptions and the restrictions that these assumptions place on data

aggregate fluctuations with national and international returns to scale cyclical movements in aggregate output factor inputs and productivity are all positively correlated across countries this article proposes a model in which positive cross country correlations of these variables result from increasing returns to the world wide variety of intermediate goods even if technology shocks are purely country specific the model also accounts for the observed positive relationship between bilateral trade volume and international comovements positive comovements can also arise with constant returns to variety but only if technology shocks are themselves strongly correlated the combination of constant returns and common shocks however tends to generate procyclical fluctuations of the trade balance

do country specific shocks matter evidence from australia and high income countries a stylized fact of global upward trend in domestic world output ratio for major small open economies is recognized in comparison with australia s dichotomous experience with the ratio this fact is used to shed light on the importance of country specific shocks for small open economies using a simple real business cycle model while it has been previously found that country specific shocks are more significant source of business cycle fluctuations than worldwide shocks for australia before the 1990s this article suggests that the country specific shocks may have become an important driver of output growth only in the early 1990s for australia

identifying uncertainty shocks using world diffusion index in this study a world diffusion index is developed to measure how uncertainty shocks have diffused among 179 economies and caused contractions in the world growth cycles this index is simply defi

are european business cycles close enough to be just one abstract we propose a comprehensive methodology to characterize the business cycle comovements across european economies and some industrialized countries without imposing any given model but trying to leave the data speak we develop a novel method to show that there is no evidence of a european economy that acts as an attractor to the other economies of the area we show that the establishment of the monetary union has not significantly increased the level of comovements across euro area economies finally we are able to explain an important proportion of the distances across their business cycles using macrovariables related to the structure of the economy to the directions of trade and to the size of the public sector

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

measuring world business cycles using kalman filtering and dynamic factor analysis the authors decompose aggregate output consumption and investment for the g7 countries into factors that are 1 common across all countries and aggregates 2 common across aggregates within a country and 3 specific to each individual aggregate in quarterly data for the period 1970 through 1993 fluctuations in all aggregates contain world and country specific common components that are both statistically significant and quantitatively important the authors find that the world and country specific common components play different roles in different business cycle episodes for each of the seven countries and that either may be dominant during a particular episode copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

an investigation of regime shifts in uk commercial property returns a time series analysis the random walk hypothesis vis a vis asset price suggests that prices traded in a market cannot be predicted based on historical information employing unsecuritized uk commercial property returns we analyse this hypothesis by investigating regime shifts or multiple changes in persistence in the series our results uncover regime shifts in both the aggregate and sector specific data specifically the shifts are less frequent in the industrial sector compared to the office retail and aggregate returns data we highlight some implications for academics practitioners and regulators

on the sources of business cycles in the g 7 abstract this paper examines sources of cyclical movements in output inflation and the term structure of interest rates in the g 7 it employs a novel identification approach which uses the sign of the theoretical cross correlation function in response to shocks to catalog orthogonal disturbances we find that demand shocks are the dominant source of output and inflation fluctuations in several of the g 7 countries the proportion of term structure variability explained by different structural sources does not depend on the horizon apart from the us and canada structural shocks are nearly uncorrelated across countries

the emergence of regional business cycle in africa a reality or myth a bayesian dynamic factor model analysis this paper examines the evolution and the underlying forces of the business cycle co movements among seven african a 7 countries over the period 1970 2016 these countries accounted for over 60 of regional gdp have abundant natural resources access to the global capital market and widely viewed as potential drivers of regional or african business cycle we model the national business cycle using real output consumption and investment we employ a dynamic factor model to decompose fluctuations in these macro variables into a regional country specific and idiosyncratic components using bayesian methods we also analyse the relative importance of some notable drivers of business cycle fluctuations found in the literature we find that the idiosyncratic component is dominating cyclical fluctuations in the a 7 countries while country specific and regional factors play a negligible role suggesting the inexistence of a common regional cycle despite deepening intra african trade among the driving variables the terms of trade shocks exert greater influence on the a 7 business cycle while exchange rate movements and changes in money supply explain sizeable fluctuations in consumption and investment in most of the a 7 countries shocks associated with changes in relative domestic oil prices monetary and fiscal policies cause large output fluctuations

global business cycles convergence or decoupling we analyze the evolution of the degree of global cyclical interdependence over the period 1960 2008 using a dynamic factor model we decompose macroeconomic fluctuations in output consumption and investment into a global factor factors specific to country groups and country specific factors we find that during 1985 2008 there is some convergence of business cycle fluctuations among industrial economies and among emerging market economies surprisingly there is a concomitant decline in the relative importance of the global factor we conclude that there is evidence of business cycle convergence within each of these two groups of countries but divergence or decoupling between them

global output growth and volatility spillovers this article examines discernable patterns of real gross domestic product gdp growth co movements across 29 countries using consistent time series data 1912 2008 of these countries only 12 are found to form three statistically significant groupings i e g6 six organization for economic co operation and development oecd european countries g4 four anglo saxon countries and g2 two major asian countries one may then conclude that inter alia geographical proximity cultural ties and the level of socio economic and financial ties among countries determine the global systematic co movements of growth rates our results indicate that any recession in the us initially engulfs other anglo saxon countries as well as g6 and g2 countries before exerting its adverse knock on effects to the rest of the world a multivariate generalized autoregressive conditional heteroscedasticity mgarch model is also used to examine the transmission of gdp growth across these three groups and their corresponding vol

sources of international business fluctuations country specific shocks or worldwide shocks abstract this paper identifies sources of business fluctuations in a two country open economy model with the structural var method focusing on the relative importance of worldwide shocks and country specific shocks unlike previous studies which define country specific shocks as labor supply shocks this study explicitly identifies three kinds of permanent shocks worldwide shocks domestic country specific shocks and foreign country specific shocks with identifying restrictions derived from a theoretical model the main finding is that u s country specific shocks are the most important in explaining u s and foreign output fluctuations except in the short run

international business cycles world region and country specific factors the paper investigates the common dynamic properties of business cycle fluctuations across countries regions and the world we employ a bayesian dynamic latent factor model to estimate common components in macroeconomic aggregates output consumption and investment in a 60 country sample covering seven regions of the world the results indicate that a common world factor is an important source of volatility for aggregates in most countries providing evidence for a world business cycle we find that region specific factors play only a minor role in explaining fluctuations in economic activity we also document similarities and differences across regions countries and aggregates jel f41 e32 c11 c32

testing for forecast consensus a panel of forecasts may be defined to be in consensus when individual forecasters place identical weights on a common latent variable we suggest this definition and formulate a dynamic latent variable model to test for consensus this method also tests whether it is valid to use the mean forecast as the consensus forecast in applications to surveys of u s macroeconomic forecasters there is greater consensus in forecasts for output growth than for inflation or unemployment but idiosyncratic forecast autocorrelation from year to year is present for most forecasters

stock market volatility and international business cycle dynamics evidence from oecd economies abstract how does a surprise movement in stock market volatility affect our forecasts of future output across countries this paper studies the time series and cross sectional responses of output to variation in stock market volatility across 27 countries over 40 years controlling for a number of country specific characteristics high levels of stock market volatility are detrimental to future output growth not only after financial crises as previously emphasized in the literature but also in non crisis periods output growth and interest rates react negatively to a random shock to volatility and revert to their means quickly thereafter moreover these results are robust after controlling for economic policy uncertainty the level of financial development and the direction of the market

the shrinking advantage of market potential abstract how does a country s economic geography evolve along the development path this paper documents recent employment growth in 18 961 regions in eight of the world s main economies overall market potential is losing importance as a correlate of local growth while local employment density is gaining importance in mature economies growth is strongest in low market potential areas in emerging economies the opposite is true though the association with market potential is also weakening there structural transformation away from agriculture can account for some of the observed changes the part left unexplained by structural transformation is consistent with a standard economic geography model that yields a bell shaped relation between trade costs and the growth of centrally located regions

exporting recessions international links and the business cycle abstract empirical evidence of decoupling typically focuses on declining business cycle correlations at low frequencies at higher frequencies business cycles strongly co move during recessions but are largely independent during non recessionary periods

business cycles synchronicity and income levels has globalisation brought us closer than ever research on business cycle linkages shows a tendency to model countries of relatively the same income levels jointly however the issue of whether these countries move along the same business cycles has not been formally investigated in the literature in this paper we take this approach and investigate whether each group of countries follows its own dynamics and is therefore subjected to the same business cycle and whether these cycles are independent of each other across income groups results indicate that high income per capita countries hics tend to be guided by stronger similarity in business cycles than countries in the middle mics and low income lics groups in search for an explanation of the business cycles synchronicity observed panel data analysis was explored the results from the robust fixed effects estimation show neither trade openness nor shocks to consumption underlie international business cycle synchronization but rather shocks to oil prices

common and country specific fluctuations in productivity investment and the current account abstract dynamic factor analysis and kalman filtering are used to construct a measure of common economic activity for the g7 countries we find that the common fluctuations are strongly associated with movements in us investment common fluctuations have substantial impact on fluctuations in both productivity and investment in these countries but very little impact on the current account country specific investment fluctuations have a significant negative impact on the current account while country specific productivity movements have little independent effect these findings are shown to be generally consistent with the predictions of a multi country dynamic model calibrated to the empirical decomposition of productivity shocks

are correlations of stock returns justified by subsequent changes in national outputs abstract in an integrated world capital market the same pricing kernel is applicable to all securities we apply this idea to the stock returns of different countries we investigate the underlying determinants of cross country stock return correlations first we determine for a given measured degree of commonality of country outputs what should be the degree of correlation of national stock returns we propose a framework that contains a statistical model for output and an intertemporal financial market model for stock returns we then attempt to match the correlations generated by the model with measured correlations our results show that under the hypothesis of market segmentation the model correlations are much smaller than observed correlations however assuming world markets are integrated our model correlations can be matched with observed correlations

globally correlated nominal fluctuations fluctuations in nominal variables aggregate price levels and nominal interest rates are documented to be substantially more synchronized across countries at business cycle frequencies than fluctuations in real output a transparent mechanism accounting for this striking feature of the nominal environment is described and quantitatively evaluated it is based on the interaction between small cross country spillovers of shocks taylor rules and domestic no arbitrage conditions the mechanism is robust to various parameterizations and extensions aligning the model with other important aspects of domestic and international fluctuations furthermore its key features are consistent with cross country forecasts from consensus survey

determinants of business cycle comovement a robust analysis abstract this paper investigates the determinants of business cycle comovement between countries our dataset includes over 100 countries both developed and developing we search for variables that are robust in explaining comovement using the approach of leamer amer econom rev 73 1983 31 variables considered are i bilateral trade between countries ii total trade in each country iii sectoral structure iv similarity in export and import baskets v factor endowments and vi gravity variables we find that bilateral trade is robust however two variables that the literature has argued are important for business cycles industrial structure and currency unions are found not to be robust

when and how us dollar shortages evolved into the full crisis evidence from the cross currency swap market abstract this paper investigates when and how the us dollar shortages evolved into the full crisis in the cross currency swap market between major european currencies and the us dollar during the turmoil of 2007 2009 using the dynamic factor model with regime switching coefficients of each swap price with respect to the latent common factor the 1 year market entered the high crisis regime soon after the onset of the subprime problem in august 2007 the 10 year market entered that regime following the collapse of bear sterns in mid march 2008 financial credit spreads have significant predictive power for switches between high and low regimes

sovereign credit spreads abstract the paper develops a structural credit risk model to study sovereign credit risk and the dynamics of sovereign credit spreads the model features endogenous default and recovery rates that both depend on the interaction between domestic output fluctuations and global macroeconomic conditions we show that sovereigns choose to default at higher levels of economic output once global macroeconomic conditions are bad this yields to default rates and credit spreads that are substantially higher compared to normal times we derive closed form expressions for sovereign debt values and default times and focus on the dynamics of sovereign credit spreads as opposed to standard theories of sovereign debt this paper s structural model generates much richer default patterns and non linearities through regime shifts in the global macroeconomic environment moreover changes in the global environment reveal the interconnectedness of the financial system

are emerging market indicators of vulnerability to financial crises decoupling from global factors abstract this paper assesses the extent to which common factors underlie indicators of vulnerability to financial crises in emerging market economies emes and whether this link is changing over time we use a bayesian dynamic common factor model to estimate their common component in a sample of up to 41 countries including both developed as well as emerging economies this permits us to interpret the component in common to both of them as a global factor we introduce time variation into the model to investigate whether indicators are decoupling from global factors over time while decoupling can be observed in a few cases the exposure to global factors in most countries tends to fluctuate around the mean broadly speaking then the answer is no

a multilevel factor model identification asymptotic theory and applications this paper studies a multilevel factor model with global and country factors the global factors affect all individuals while the country factors affect only those within each specific country a sequential procedure to identify the global and country factors separately is proposed in the initial step the global factors are estimated by canonical correlation analysis using this initial estimator the principal component estimators pces of the global and country factors are constructed it is shown that the pces estimate the spaces of the global and country factors consistently and are normally distributed in the limit several information criteria that can estimate the numbers of the country factors are proposed the number of the global factors is assumed to be known extensive simulation results demonstrate that the sequential procedure and the information criteria work well in finite samples the method of this paper is applied to 25 oecd countries to identify international business cycle it is reported that the method extracts a global factor reasonably well

international demand and liquidity shocks in a svar model of the australian economy a structural vector autoregressive model of the australian economy that allows for international shocks from the usa japan as well as world commodity prices is specified and estimated for the period 1979 1999 a block exogenous structure linking the three countries is imposed the international linkages are modelled using a factor structure to circumvent problems from estimating large scale dynamic models the factors are estimated recursively using a kalman filter and are found to represent aggregate demand and liquidity shocks for the usa and japan respectively the key empirical result is the usa shocks are the dominant source of international shocks on the australian economy with the japanese economy having a dampening effect on the usa shocks the empirical results also show that australian monetary policy responds to domestic conditions rather than international monetary policy

sources and propagation of international output cycles common shocks or transmission abstract this paper studies the generation and transmission of international cycles in a multi country model with production and consumption interdependencies two sources of disturbance are considered and three channels of propagation are compared technology disturbances which are mildly correlated across countries are more successful than government expenditure disturbances in reproducing actual data the presence of a common component to the shocks and of production interdependencies appear to be crucial in quantitatively matching the properties of the data

identifying the common component of international economic fluctuations a new approach in this paper we develop an aggregation procedure using time varying weights for constructing the common component of international economic fluctuations the methodology for deriving time varying weights is based on some stylised features of the data documented in the paper the model allows for a unified treatment of cyclical and seasonal fluctuations and also accommodates the dynamic propagation of shocks across countries we find evidence for a world business cycle as well as evidence for a distinct european common component we also find some evidence that macroeconomic fluctuations have become more closely linked across industrial economies in the period after 1973 the world economy has become more closely integrated in recent years due to increasing trade and financial flows across countries this has spurred interest in the question of how the ongoing phenomenon of globalisation has affected the transmission and propagation of business cycle fluctuations across national borders an important question in this context is whether a substantial fraction of economic fluctuations are country specific or if there exists a world business cycle which might be defined as fluctuations that are common across all countries more generally the comovement of macroeconomic aggregates across different countries has become a topic of increasing interest in both academic and policy circles these issues have implications in a number of dimensions an empirical analysis of the relative importance of country specific versus common international fluctuations is of relevance for determining the structure of certain classes of international business cycle models from a policy perspective strong comovement of output across countries at business cycle frequencies implies that external trade would be unlikely to play a significant role in dampening fluctuations domestic policies aimed at affecting the real exchange rate and thereby attempting to boost net exports in the short run would then tend to have limited impact the degree of synchronisation of business cycles across countries also has important implications for short run international policy coordination and for assessing the feasibility of monetary unions therefore identifying and analysing the common component of international economic fluctuations is relevant from a number of different perspectives

world country and sector factors in international business cycles do sector specific factors common to all countries play an important role in explaining business cycle co movement we address this question by analyzing international co movements of value added va growth in a multi sector dynamic factor model the model contains a world factor country specific factors sector specific factors and idiosyncratic components we estimate the model using bayesian methods for 30 disaggregated sectors in the g7 economies for the 1974 2004 period our findings show that although there is a substantial role for sector specific factors fluctuations are dominated by country factors the world factor appears to play a minimal role because when using aggregate data the world factor captures both the factor common to all countries and industries and the factor common to the same industry across countries we then examine how these factors evolved as globalization deepened over the past two decades our results suggest that business cycles at a disaggregate level have not become more synchronized internationally this is mainly driven by a substantial fall in the volatility of world shocks during the globalization period rather than a lower sensitivity of sectoral growth to world factors our results also reveal that world factors appear to be more important for industries with a higher level of international vertical integration

a cross country financial accelerator evidence from north america and europe a growing literature has examined the importance of credit market imperfections for macroeconomic fluctuations the so called financial accelerator a related literature has provided evidence of international and regional co movements in macroeconomic fluctuations we tie together these strands of the literature in that we investigate the importance of both cross country and country specific credit cycles in explaining output fluctuations using data for four major economies and two world regions from 1973 to 2001 we find that both regional and country specific components of indicators of credit availability are powerful in explaining output movements this research provides the first empirical evidence of a cross country financial accelerator
