Country size and business cycle volatility: Scale really matters

In a recent study Andrew Rose found that country size does not matter for several economic outcomes [Rose, A.K., 2006. Size really doesn't matter: In search of a national scale effect. J. Japanese Int. Economies 4, 482–507]. However, he did not consider the effect that country size may have on business-cycle volatility. To investigate the empirical relationship between business cycle volatility and country size, we use a panel data set that includes 167 countries from 1960 to 2000. The results suggest very strongly that the relationship between country size and business cycle volatility is negative and statistically significant. This implies that smaller countries are subject to more volatile business cycles than larger countries. This holds both in a simple bivariate model and when we include Rose's control variables and openness. Moreover, the results are robust to different sample periods and several detrending methods. It follows that country size really matters, at least in terms of cyclical fluctuations. J. Japanese Int. Economies 21 (4) (2007) 424–434.

How Pervasive is the World Business Cycle?

The paper tries to establish whether business-cycle synchronization across countries is due to a single world business cycle, to a diversity of regional business cycles or a combination of both. The methodology used does not impose any prior hypothesis about the existence of a business cycle with a specific regional composition. If regional business cycles exist, the regional composition would be estimated from the data used and the countries will form a region. The results indicate that there are four common components, but none specific to a geographical or cultural region. The only division found is between high and middle income countries. However inside these groups we can find some sets of countries that have a high degree of commovement. We will call these last groups clusters.     

Endogenous Markups,Intensity of Competition,and Persistence of Business Cycles

In order to study the propagation mechanism of business cycles, in particular to investigate how the intensity of competition affects market structure and output persistence over business cycles, this paper presents a real business-cycle model with imperfect competition and increasing returns to scale. This analysis considers the markups of price over cost to be endogenous. With endogenous markups, two standard forms of oligopolistic competition—Bertrand and Cournot—are considered. Results show that: (1) the propagation mechanism in the sense of output persistence is greater under Cournot; (2) the propagation mechanism is unequivocally greater with imperfect competition, regardless of whether markups are endogenous or not; and (3) under imperfect competition, the propagation mechanism is greater with endogenous markups than with exogenous markups. Overall, these results suggest that more intense competition produces lower persistence in output growth and, thus, a weaker propagation mechanism. In a calibration exercise, these differences were also found to be quantitatively important.     

Does the choice of detrending method matter in demand analysis?

This paper examines the selection of optimal detrending methods in demand analysis with time series data by measuring the distortionary effect of linear filters on the spectrum of detrended time series. The paper identifies substantial distortions of popular detrending methods in economics (including first-differencing and deterministic linear detrending), while the Hodrick–Prescott and Baxter–King filters produce much smaller distortions in detrended time series. Consequences of alternative detrending approaches are further illustrated by estimating the almost ideal demand system in Japan for major consumption categories.     

A COMPARATIVE ANALYSIS OF THE SYNCHRONISATION OF BUSINESS CYCLES FOR DEVELOPED AND DEVELOPING ECONOMIES WITH THE WORLD BUSINESS CYCLE

Globalisation brought about worldwide changes, including economic and financial integration between countries. The objective of this paper is to establish if there is synchronisation between developed and developing countries with the world cycle. Research results show that business cycles have become less volatile after globalisation, but there is not much consensus on whether business cycles have become less or more synchronised since globalisation. Little research has been done on co‐movement between emerging markets, such as South Africa, and the world business cycle. This paper derives common factors for developed and developing countries by applying principal component analysis (PCA) to output, consumption and investment data, which represents the countries' business cycles. The empirical analysis shows co‐movement between some countries and the world business cycle (G7 countries as proxy). The results suggest that there are idiosyncratic and globally common shocks, which play different roles over time in different countries. The paper goes on to suggest that there are clear differences in how developed and emerging markets co‐move with the world business cycle. A key finding is that the co‐movement between developing economies and the world business cycle has increased since globalisation. This research also confirms previous research that most economies follow the world business cycle when large shocks – such as the recent economic downturn – occur. This has implications for forecasting the business cycle, especially in times of economic turmoil.

Is there a business cycle in Singapore? Is there a Singaporean business cycle?

This paper explores the existence and examines the characteristics, if any, of business cycles in Singapore. Specifically, the authors ask: Is there a business cycle in Singapore? Is there a Singaporean business cycle? Unlike earlier studies, this paper investigates whether or not there exists a business cycle in Singapore and employs cross-spectral analysis and factor analysis which have advantages over the time-domain techniques. The study shows that there is a business cycle in Singapore and its frequency does not coincide with the periodicity of the two recessions experienced by the country. However, the business cycle is not in any meaningful way Singaporean, as evidenced by the existence of three international factors explaining about 99 percent of the common variance of the series. The idiosyncratic factor is well below 1 percent in all Association of Southeast Asian Nations countries with the exception of the Philippines. The findings have a number of significant implications both from the theoretical and policymaking viewpoint.     

CYCLICAL UNEMPLOYMENT AND CYCLICAL OUTPUT: AN ESTIMATION OF OKUN'S COEFFICIENT FOR SOUTH AFRICA

Persistently high unemployment in South Africa, especially in the face of improved economic conditions since 1994, begs the question: Does unemployment in South Africa respond to changes in output? Okun's law refers to the inverse relationship that exists between cyclical output and cyclical unemployment. This paper estimates Okun's coefficient for the South African economy, using annual data from 1970‐2005. Output and unemployment are decomposed into their trend and cyclical components, using a variety of detrending methods. The presence of structural breaks in Okun's relationship is also investigated, while cointegration analysis was also considered. Evidence of a statistically significant relationship between cyclical output and cyclical unemployment are found in both symmetric (estimates range from ?0.77 to ?0.16) and asymmetric (estimates range from ?0.77 to ?0.18) specifications of Okun's law, irrespective of the detrending technique. However, cyclical unemployment constitutes only a relatively small fraction of total (observed) unemployment, which implies that a more expansionary macroeconomic policy stance might only have a limited impact on total unemployment in South Africa.     

International and intranational business cycles

This paper surveys and analyses the international real businesscycle literature. We re-explore two international business cycleanomalies emphasized by Backus, Kehoe, and Kydland (1995) aswell as establishing the pattern of productivity growth betweenindustries and countries. We then compare these findings forthe international business cycle to those obtained for databetween regions within a country - the so-called 'intranationalbusiness cycle'. Importantly, the intranational business cycleis a natural environment for thinking about the interactionsbetween economies when there are no trade frictions and whenthere are not multiple currencies. We summarize our findingswith a comparison between the stylized facts for internationaland intranational business cycles and draw some policy conclusions.     

跨经济周期的资产轮动模式——兼谈美林投资钟的缺陷及修正

美林投资钟是以经济周期为框架的最为著名的资产配置模型,但其主要是提供了一种研究的思路和方式,依然存在不足和缺陷。关林投资钟把滞胀作为经济周期第四阶段的假定是有悖于传统经济学的;凯恩斯主义认为,滞胀是经济周期中的特殊现象,而不是必经阶段。文章从非经典周期资产配置的角度,在理论上对美林投资钟作出修正和补充,以使之更完整和适用。     

China's economic fluctuations and consumption smoothing: Is consumption more volatile than output in China?

This paper provides a fundamental study of China's consumption and output fluctuations. The most recent literature reports that, in the post-1978 period, detrended consumption is significantly more volatile than detrended output in China. This indicates the inability to impose consumption smoothing. However, in those previous studies, consumption of durables, which has some features of capital, as discussed in the real business cycle literature, was not separated from private consumption. This paper is the first to estimate consumer durables for China and their service values following the method introduced in Cooley and Prescott (1995). We adjust the consumption measure to make it consistent with the real business cycle literature, and find that consumption of durables is much more volatile than output, but non-durable consumption is less volatile than, and less correlated with, output that provides evidence that supports consumption smoothing in China.     

The European business cycle

This paper deals with the existence and identification of acommon European growth cycle. Univariate Markov switching autoregressionsare used for individual countries in order to detect changesin the mean growth rate of industrial production. A Markov switchingvector autoregression model is then used to identify a commoncycle in Europe. Three important results are obtained: we finda common unobserved component governing European business cycledynamics, suggesting the existence of a common business cycle;we propose a dating of the business cycle, both for an indexof industrial protection and GDP, and both chronologies appearto be consistent; and finally we retrieve an important set ofstylized facts and relate these with those reported for theUS. Finally two further issues are investigated: first, thecontribution of the European business cycle to the individualcountry cycles; and second, we undertake an impulse responseanalysis to investigate the response of each individual countryto European expansions and recessions.     

Do Firms Time Their Pollution Abatement Investments Optimally?

In this paper we develop an equilibrium business-cycle model for an economy with both clean and dirty (polluting) plants. We conclude that the best time to implement cleaner production technologies is during a slowdown of the economy. Due to external effects and market failures the timing of pollution abatement investments is not expected to be optimal in the real world. We test the optimality of the timing of those investments with data for Germany, the Netherlands, and the USA. It appears that for more than 25 per cent of the sectors pollution abatement investments show significant counter-cyclical behaviour, while in 10 per cent of the sectors these investments are pro-cyclical.     

The Mundane Economics of the Austrian School

The Austrian School of economics—the causal-realist, marginalist, subjectivist tradition established by Carl Menger in 1871—has experienced a remarkable renaissance over the last five decades. It is not always clear, however, exactly what distinguishes the Austrian School from other traditions, schools of thought, approaches, or movements within economics and its sister disciplines. This paper argues that Austrian economics, while part of a broader tradition emphasizing the coordination of the market order, is nonetheless a distinct kind of economic analysis, and that its essence is not subjectivism, the market process, or spontaneous order, but what I call “mundane economics”—price theory, capital theory, monetary theory, business-cycle theory, and the theory of interventionism. Call this the “hard core” of Austrian economics. I argue that this hard core is (1) distinct, and not merely a verbal rendition of mid-twentieth-century neoclassical economics; (2) the unique foundation for applied Austrian analysis (political economy, social theory, business administration, and the like); and (3) a living, evolving body of knowledge, rooted in classic contributions of the past but not bound by them. Most Austrian economists from Menger to Rothbard devoted their energies to developing and communicating the principles of mundane economics, not because they failed to grasp the importance of time, uncertainty, knowledge, expectations, institutions, and market processes, but because they regarded these issues as subordinate to the main task of economic science, namely the construction of a more satisfactory theory of value, production, exchange, price, money, capital, and intervention.     

The South African Financial Cycle and its Relation to Household Deleveraging

This paper considers the extent to which South African households have deleveraged, since the global financial crisis of 2007/2008. We extend the official South African Reserve Bank business cycle methodology to date financial cycles, from which we identify the peaks and troughs of the South African financial cycle going back to 1966. Our composite financial cycle index peaks in April 1974, January 1984 and May 2007; it has bottomed out in July 1979 and February 1999. Thus, we still await the trough. We further compare and contrast the deleveraging process in the current downward phase to the experiences from previous financial cycles. We find that the average period of the financial cycle in South Africa is much longer (approximately 17.3 years) than that of the business cycle (approximately 5.8 years), and that deleveraging has not yet matched the degree of deleveraging seen in previous downward phases. Our results suggest that further deleveraging is necessary, before we can expect to turn the financial corner.     

External influences in Nordic business cycles, 1870–1988

This paper considers the relationship of the Nordic business cycle to the world business cycle using annual output data spanning 1870–1988. The paper studies the Nordic and a set of non-Nordic countries separately and finds evidence for both a Nordic and a world business cycle. Output movements in the individual Nordic countries are connected through the Nordic business cycle and are less affected by the world business cycle. There is no significant change in the behavior of the business cycle in the Nordic countries between 1873–1913 and 1948–1988.     

Financial Factors in the Business Cycle of a Small Open Economy: The Case of Korea

Financial factors influencing the business cycle have received considerable attention in recent years in the aftermath of the global financial crisis in 2008. This paper examines the role of financial factors in the business cycle by considering Korea, a small open economy, that experienced a severe financial crisis in 1997 as well as the recent global financial crisis. We estimate small open economy Bayesian DSGE (dynamic stochastic general equilibrium) models with financial factors and analyze the role of these financial factors in the business cycle in the context of Korea. The results indicate that the model based on an endogenous financial accelerator and a modified monetary policy rule provides a better explanation to the data than that without the financial factors and justify the recent attention to financial factors influencing the business cycle.     

Business cycle transmission and interdependence between Japan and Australia

This paper investigates business cycle transmission and interdependence between Australia and Japan over the period 1961.1–1994.4. Vector autoregression (VAR) and vector error correction (VEC) models were constructed utilizing GDP/GNPs, producer prices, interest rates and money supplies. The model is tested for cointegration. Two cointegrating vectors are found, and a vector error correction (VEC) model is estimated. The coefficients and the F-tests of the VEC are used to measure the effect of one economy upon the other. Impulse responses from a VAR are examined for evidence of business cycle transmission, and recursive least squares estimates are used to check for structural change in the relationship. Figures are used to graphically demonstrate these relationships and have been collected in an appendix, which can be found at the end of the text.While the two countries engage in a close trading relationship, the two economies are found to be only somewhat interdependent in macroeconometric terms. Japan is found to transmit some of its business cycle fluctuations to Australia, but there is little reverse transmission.
