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.     

Oil price uncertainty and the business cycle: Accounting for the influences of global supply and demand within a VAR GARCH-in-mean framework

ABSTRACT

This article reinvestigates the influence of oil price uncertainty on real economic activity in the United States using a four-variable VAR GARCH-in-mean asymmetric BEKK model. In contrast to previous studies in this area, the analysis focuses on business cycle fluctuations and we control for global supply and demand factors that might affect the real price of oil, its volatility as well as the US economy. We find that – even after accounting for these factors – oil price uncertainty still has a highly significant negative influence on the US business cycle. Our computations show that the effect is economically important during several periods, mostly after a significant variance shift in the mid-1980s. We simultaneously estimate the effect on the global business cycle but find that it is comparatively weak. Finally, significant spillover effects in the GARCH model suggest that oil price volatility is a gauge and channel of transmission of more general macroeconomic shocks and uncertainty. These linkages are particularly strong in case of unexpected bad news.     

Mirowski's Machine Dreams

Abstract

John Wade formulated, in 1826 and 1833, two models of cyclical fluctuations most likely to be the first in the literature. They are fully endogenous, based on a cobweb-like mechanism affecting not agricultural production, as was customary at the time, but manufacture. Wade's earlier model relies on a threshold of price change before the reaction of demand and supply halts and reverses the movement, while the second is gradual and based on a delay in the producers' reaction. Wade was also among the first to claim that crises return with a certain regularity and to estimate their period. This paper examines and compares Wade's contributions to early business cycle theory, places them in context, and surveys the scanty references to this pioneering work in the literature.     

The time-varying characteristics of the Chinese financial cycle and impact from the United States

ABSTRACT

Although there have been many empirical studies about the financial cycle since the financial crisis of 2008, few have analysed the structural changes in the Chinese financial cycle over time. The Chinese financial development process is short, and it is difficult to obtain accurate results on the measurement of the financial cycle. Based on wavelet analysis, this paper analyzes the time-varying characteristics of the Chinese financial cycle and the relationship between the financial and business cycles. In addition, we measure the impact from the United States. This paper draws three conclusions. Firstly, in terms of the characteristics of cycles, the existence of Chinese business cycle and financial cycle is proved, while the credit cycle, leverage cycle, stock market cycle and property cycle are quite different. Specifically, China has a 5.8-year credit cycle, an 8-year stock market cycle, 3.4-year and 12-year business cycles and a 15-year leverage cycle. Secondly, the financial cycles can serve as leading indicators of the business cycle, though the relationships between them are change overtime. Finally, the United States has a significant impact on the Chinese financial cycle with a ‘decoupling-recoupling’ effect, which is mainly reflected in the leverage cycle and the stock market cycle.     

On the measurement and analysis of aggregate economic activity for China: the coincident economic indicators approach

This paper reviews some of China's high-frequency economic indicators and our principal findings on their selection and use. Our aim is to develop a composite index of coincident economic indicators (coincident economic index, CEI) which can be used to obtain timely information on the present state of the China's economy and provide an appropriate measure to analyze China's short-term macroeconomic dynamics. Notably, combining industrial production, retail sales, manufacturing employment, income of financial institutions and passenger traffic volume, they work well as the method for dating business cycles for China. It shows that, over the past two decades, there was one marked recession which occurred in 1988:8 to 1989:12. In addition to this business cycle chronology we also develop a growth cycle chronology based on the deviations from trend of the CE which shows that there have been four cyclical slowdowns since 1986. Whereas GDP growth lacks cyclical movements and appears to be dominated by trend and irregular movements, in contrast to GDP, the CEI works well as a measure of cyclical dynamics and can contribute to the analysis of short-term fluctuations of Chinese economic activity relative to its long-term growth.     

Accounting for the business cycle: Nominal rigidities, factor heterogeneity, and Austrian capital theory

An Austrian interpretation of the New Keynesian small menu cost model of the business cycle is proposed. Austrian and New Keynesian business cycle theories share the feature that the cycle is generated by rigidities which prevent the economy from adapting instantaneously to changing conditions. Austrian business cycle theory is capital-based, focusing on credit expansion which artificially lowers interest rates and causes an investment boom and unsustainable business expansion. In contrast, the New Keynesian small menu cost model of the business cycle is based on nominal rigidities which prevent markets from clearing. Small menu costs introduce dichotomous behavior, where firms find it locally optimal to avoid instantaneous output price adjustments in the face of the cost, but this local optimum results in economy-wide output and employment fluctuations which are much greater in relative magnitude. The small menu cost model of the business cycle is extended and reinterpreted in light of Austrian business cycle theory with heterogeneous, multiply-specific capital, thus providing a rigorous formalization of the Austrian business cycle. The Austrian interpretation of this New Keynesian model fortuitously addresses several of its shortcomings. JEL classification B53, E12, E23, E32     

Remittances over the business cycle: Theory and evidence

We examine the behaviour of remittances over the business cycle and their potential to act as a ‘stabilizer’ during periods of high business cycle volatility. Two main findings are reported. First, remittances are less volatile than other foreign currency flows and do not appear to systemically comove with business cycle fluctuations. Second, remittances are relatively stable even during episodes of sharp business cycle volatility, such as those associated with sudden stops and financial crises. We also provide an overview of the theoretical literature on the implications of different motives to remit for the cyclical behaviour of remittances.     

The Effects of Business Cycles on Growth - Time Series Evidence for the G7-countries Using Survey-based Measures of the Business Cycle

The paper analyses whether business cycle fluctuations affectlong-run growth. This hypothesis is tested using quarterly timeseries for the G7-countries. A vector-autoregressive model containingtotal factor productivity and a survey-based direct measureof the business cycle is estimated. In this vector-autoregression,technology and business cycle shocks are identified based onthe assumption that productivity-improving measures need sometime and, thus, there is no contemporaneous response of productivityto a business cycle innovation. The results suggest that positivebusiness cycles shocks have a small negative impact on long-runproductivity. However, the results appear to be not robust againstchanges in the empirical model.(JEL E32, O41)     

Fisheries Management Under Cyclical Population Dynamics

Cycles in environmental conditions (e.g., sea-surface temperature) directly impact fish growth. This paper extends the classical Gordon-Schaefer fishery model by replacing the constant growth rate with a cyclical growth rate. The optimal harvest rate is shown to fluctuate, but the cycle of the harvest rate lags the cycle of the biological growth function with the highest harvest rate occurring after biological conditions start to decline. Simulations contrast various fishing policies and illustrate the proclivity to crash a fishery if it is wrongfully managed as if there is a constant growth rate with i.i.d. environmental shocks. Finally, we show that small cyclical fluctuations in one species can result in large fluctuations in the optimal harvest rate of another species if the fish species are interlinked through predator-prey relationships.      

The equity price channel in a New-Keynesian DSGE model with financial frictions and banking

This paper studies the role of the equity price channel in business cycle fluctuations, and highlights the equity price channel as a different aspect to general equilibrium models with financial frictions and, as a result, emphasizes the systemic influence of financial markets on the real economy. We develop a canonical dynamic general equilibrium model with a tractable role for the equity market in banking, entrepreneur and household economic activities. The model is estimated with Bayesian techniques using U.S. data over the sample period 1982Q01–2015Q01. We show that a dynamic general equilibrium model with an equity price channel well mimics the U.S. business cycle. The model reproduces the strong procyclicality of the equity price. The equity price channel significantly exacerbates business cycle fluctuations through both financial accelerator and bank capital channels. Our results support the increasing emphasis on common equity capital in Basel III regulations. This is beneficial in terms of financial stability, but amplifies and propagates shocks to the real economy.     

Endogenous Money Supply and the Business Cycle

This paper documents changes in the cyclical behavior of nominal data series that appear after 1979:Q3 when the Federal Reserve implemented a policy to lower the inflation rate. Such changes were not apparent in real variables. A business cycle model with impulses to technology and a role for money is used to show how alternative money supply rules are expected to affect observed business cycle facts. In this model, changes in the money supply rules have almost no effect on the cyclical behavior of real variables, yet have a significant impact on the cyclical nature of nominal variables.Journal of Economic LiteratureClassification Numbers: E32, E42, E50.     

Global financial cycle and Brazil’s financial integration

ABSTRACT

Recent studies have discussed the influence of the global financial cycle on capital flows to emerging and developing countries. This paper evaluates the relationship between the greater degree of financial integration, and macroeconomic performance over the last two decades in Brazil. The literature has highlighted the Brazilian experience as being paradigmatic among emerging countries regarding the relationship between financial integration and regulation of capital flows to deal with boom and bust cycles. Methodologically, we employ a vector autoregressive model with error correction that allows us to evaluate the cointegration between the variables. Our main hypothesis is that a greater degree of financial integration is associated with negative developments in variables such as gross domestic product, country risk, interest rates, and exchange rate volatility. In addition, this study presents a further contribution by observing the existence of the interaction between the consequences of financial integration and the global financial cycle. More specifically, we found that: (i) an increase in the degree of financial integration generates deeper effects in downward periods of the global financial cycle; and (ii) a decline in that cycle generates greater impacts when a higher degree of financial integration is present.     

Balance Mechanics and Business Cycles

Abstract

Many mainstream business cycle theories were not able to cope with the financial crisis theoretically. With his concept of balance mechanics, the German economist Wolfgang Stützel developed a framework for comparing different theories of business cycles which helps to understand the reasons for this inadequacy. This paper works out Stützel’s considerations and his four “model cases” of cycles more systematically and shows how the theories of the business cycle Stützel mentioned are related to theories discussed today. Modern business cycle theories did not cover all “model cases” and therefore had a blind spot.     

Emil Lederer’s Theory of Economic Fluctuations and the Role of Financial Institutions

Abstract

Emil Lederer was characterized as the “leading academic socialist of Germany in the 1920’s” by Joseph Schumpeter and was a highly respected economist of his time. However, most aspects of his work remain totally unexplored. This paper focuses on Emil Lederer’s theory of economic fluctuations defending the thesis that certain aspects of Lederer’s conceptualization of economic fluctuations underwent considerable modifications when his 1925 article Konjunktur und Krisen is compared with his 1938 book Technical Progress and Unemployment, a shift unacknowledged so far in the literature. In his first attempt to tackle the issue, in Konjunktur und Krisen (1925), Lederer had constructed an explanation consistent with the so-called “disproportionality theory” introduced by Tugan-Baranowsky (codified as “early Lederer”). However, Lederer’s conception of the business cycle during the 1930s and especially in his major work Technical Progress and Unemployment underwent considerable modifications. Lederer’s (1938 Lederer, E. 1938. Technical Progress and Unemployment, Geneva: King and Son.  [Google Scholar]) analysis is, apparently, very ‘Schumpeterian’ (codified as “late Lederer”). In this version of his theory, the cycle is explained by supply-side factors, and more specifically by technical change. Additionally, Lederer’s view on the role of financial institutions (credit and banks) with regards to business cycles is analysed. Lederer avoided attributing a causative role to monetary factors. The interrelation between ‘real’ factors and financial institutions constitutes an essential element in his analysis of the business cycle.     

Hong Kong Output Dynamics: An Empirical Analysis

Abstract. Advanced statistical techniques are used to analyze Hong Kong output dynamics. Hong Kong, Japan and the US are found to share some common long‐term and short‐term cyclical variations. While the Hong Kong economy is susceptible to external shocks and Granger‐caused by the other two economies, local factors account for a large proportion of output growth variability and uncertainty. On the transmission mechanism, the selected trade and financial variables have incremental explanatory power but do not lessen the ability of lagged output variables to explain Hong Kong growth dynamics. Interestingly, the US does not appear to exert undue influences on Hong Kong.     

UNDERSTANDING THE INTERACTION BETWEEN INTERNATIONAL AND EURO AREA OUTPUT VOLATILITY

This paper addresses two main questions. First, it seeks to establish whether the stylized facts of the ‘great moderation’ that have been documented for the UK and US economies can be found for the Euro area. Second, it explores possible explanations for any changes that have occurred in the volatility of Euro area output fluctuations. In examining why business cycles have moderated, much of the existing literature has tended to concentrate on a few key factors. These include shifts in the structure of the economy, improved monetary policy and a ‘good luck’ factor. This paper, however, follows a relatively new branch of the great moderation literature by focusing on whether international business cycle linkages have changed in a way that may have perpetuated the dampening in Euro area output fluctuations. The results show Euro area output fluctuations to have significantly reduced in variability over the last quarter of a century. The results go on to highlight that, although Euro area cycles differ little from rest of the world cycles, the moderation in Euro area output fluctuations is only marginally due to changes in international business cycle linkages and smaller international and domestic shock variances.     

Cost utility of palivizumab prophylaxis among pre-term infants in the United States: a national policy perspective

Abstract

Objective:

The cost-effectiveness of palivizumab has previously been reported among certain guideline-eligible, high-risk premature infants in Medicaid. Because guideline authorities base decisions on a national perspective, the economic model of palivizumab was adapted to include all infants, that is, public and privately insured patients (60% of palivizumab use is public, 40% is private).

Methods:

This study examined four groups of premature infants without chronic lung disease of prematurity or congenital heart disease: (1) <32 weeks gestational age (wGA) and ≤6 months chronologic age (CA); (2) 32–34 wGA, ≤3 months CA, with 2009 American Academy of Pediatrics (AAP) risk factors (RFs); (3) 32–35 wGA, ≤6 months CA, with 2006 AAP RFs; and (4) 32–35 wGA, ≤6 months CA, with ≤1 RF. An average estimate was used between public and private payors for (1) background rates of respiratory syncytial virus hospitalization (RSV-H), (2) direct medical costs associated with RSV-H, and (3) cost of palivizumab. Incremental cost-effectiveness ratios (ICERs) are reported in cost per quality-adjusted life-year (QALY) gained. Sensitivity analyses were performed.

Results:

Palivizumab saved costs and improved QALYs among infants <32 wGA. Palivizumab was cost-effective in infants 32–34 wGA with 2009 AAP RFs ($44,774 per QALY) and in infants 32–35 wGA with 2006 AAP RFs ($79,477 per QALY). The ICER for infants 32–35 wGA with ≤1 RF was $464,476 per QALY. Influential variables in the sensitivity analysis included background rate of RSV-H and cost and efficacy of palivizumab.

Limitations:

The results are not generalizable to populations outside of the US. The model did not examine all RFs. The wholesale acquisition cost was used as a payment benchmark; actual price paid by end providers varies.

Conclusions:

From a national policy perspective, palivizumab remained cost-effective for publically and commercially insured, guideline-eligible, high-risk premature infants. Palivizumab was not cost-effective in infants of 32–35 wGA with ≤1 RF.     

Sluggish US employment recovery after the Great Recession: Cyclical or structural factors?

This paper aims at investigating the causes of the observed departure of employment path from the GDP movements occurred in US in the late of 2008 onwards. Starting from a production function approach, and assuming that the TFP growth is explained by variables linked to the business cycle, we are able to formulate an extended version of Okun’s law based on cyclical factors. Out-of-sample forecasting for the period 2008 onward shows that predicted US employment is on average 1.7% above the observed one, meaning that this gap cannot be attributed to identified cyclical factors.     

Introduction: Is the European Union Capable of Integrating Diverse Models of Capitalism?

ABSTRACT

The causes and consequences of the Euro crisis have led comparative political economy scholars to question whether European integration can accommodate diverse models of capitalism. This special issue addresses two important questions about the compatibility of diverse growth models within the European Union (EU): Are some growth regimes better suited to European integration than others? and does the EU favour a particular constellation of domestic institutions? Contributions within this special issue provide a qualified yes to these questions, concluding that the EU favours export-led growth models whilst it penalises and discourages domestic consumption-oriented growth paths, particularly those that are financed by debt accumulation. While recent comparative capitalism literature highlights that European monetary integration has favoured export-led growth regimes, contributions in this special issue outline that the EU’s prioritisation of export-led growth over domestic demand-led growth is present in other facets of integration, including EU accession, financial integration, the free movement of people, fiscal governance and the Europe 2020 growth strategy. Findings here provide important insights for both the European integration and comparative capitalism literature, highlighting that the unique economic ties being forged within the European project may be problematic for those countries outside northwestern Europe and for workers in low-wage domestic sectors.     

Real-time forecasting US GDP from small-scale factor models

We show that the single-index dynamic factor model developed by Aruoba and Diebold (Am Econ Rev, 100:20–24, 2010) to construct an index of the US business cycle conditions is also very useful to forecast US GDP growth in real time. In addition, we adapt the model to include survey data and financial indicators. We find that our extension is unequivocally the preferred alternative to compute backcasts. In nowcasting and forecasting, our model is able to forecast growth as well as AD and better than several baseline alternatives. Finally, we show that our extension could also be used to infer the US business cycles very precisely.
