Purpose: This paper aims to examine Nigeria's dynamic output and output volatility connectedness with USA, China and India using quarterly data from 1981Q1 to 2019Q4. Design/methodology/approach: The study adopted the network approach of Diebold and Yilmaz (2014) and used the normalized generalized forecast error variance decomposition from an underlying vector error correction model to build connectedness measures. Findings: The findings show that the global financial crisis (GFC) increased the connectedness index far more than the 2016 Nigeria economic recession. The moderate effect of the 2016 Nigeria economic recession on the connectedness index underscores the fact that Nigeria is a small, open economy with minimal capacity to spread output shock. For both real output and its volatility, the total connectedness index rose smoothly and systematically through time, thereby leaving the economies more connected in the long run. Originality/value: To the best of the authors' knowledge, this paper is among the first to examine Nigeria's dynamic output and output volatility connectedness with the USA, China and India using new empirical insights from the GFC versus 2016 Nigerian recession. The study, therefore, concludes that the Nigerian economy should be diversified immediately as a hedge against future real output shocks, while the USA, China and India should maintain and sustain their current policy frameworks to remain less vulnerable to real output shocks.

In this article, we empirically study the time-varying bilateral causality between commodity prices, inflation and output in China. We first perform a series of parameter stability tests and find strong evidence of instability in the parameters estimated for Granger causality tests. We then use the bootstrap rolling window approach to test the causality and find that the causality from commodity prices to both inflation and output is time-varying in the entire sample period and asymmetric in different phases of the business cycle. We also find evidence of the causality from both inflation and output to commodity prices in certain sub-periods. Further discussion on the cost-price mechanism through which the economy fluctuates cyclically suggests that the dynamic causality between commodity prices and inflation contributes to understanding the nature of economic fluctuations and to forecasting economic crises. Overall, our results provide a new perspective to disentangle economic fluctuations. [ABSTRACT FROM PUBLISHER]

This paper investigates the effects of China on the BRIS countries, namely Brazil, Russia, India and South Africa. We identify Chinese supply and demand shocks and assess their transmission to BRIS in a structural dynamic factor model framework estimated over the period 1995Q2-2009Q4. The findings show that Chinese supply shocks are more important than its demand shocks. Supply shocks produce positive and significant output responses in all BRIS countries. And while these supply shocks have a permanent impact on the BRIS countries, the effects of demand shocks are short-lived. Both supply and demand shocks are transmitted through trade rather than financial linkages. However, the responses of the BRIS countries are heterogeneous and therefore require country-specific policy responses. [ABSTRACT FROM AUTHOR]

China's GDP growth slowdown and a surge in global financial market volatility could both adversely affect an already weak global economic recovery. To quantify the global macroeconomic consequences of these shocks, we employ a GVAR model estimated for 26 countries/regions over the period 1981Q1 to 2013Q1. Our results indicate that (i) a one percent permanent negative GDP shock in China (equivalent to a one-off one percent growth shock) could have significant global macroeconomic repercussions, with world growth reducing by 0.23 percentage points in the short-run; and (ii) a surge in global financial market volatility could translate into a fall in world economic growth of around 0.29 percentage points, but it could also have negative short-run impacts on global equity markets, oil prices and long-term interest rates.

This article examined the time-varying effects of external shocks that determine inflation on Chinese and Korean consumer price index (CPI) inflation, using data from the period 2010:1 to 2013:4. For this experimentation, we adopted the Kalman filter algorithm. Key findings include the following: first, the lagged CPI inflation is the main determinant of inflation rate in both China and Korea that is significant and has positive effects. Second, as expected, the effects of independent variables on CPI inflation rate have a considerable difference in China and Korea from the coefficients’ size and sign. Especially, China’s CPI inflation is mainly affected by domestic output growth, while Korea is more readily affected by external shocks. Third, we confirmed the time-varying effects. For instance, the positive effect of the output variable is decreasing in the Chinese inflation equation, but its negative effect is decreasing in the Korean inflation equation. Finally, we can guess Korea is a more import dependent economy than China and also the trends of estimated coefficients of China’s inflation are changing similarly to Korea. It has been proved from recent changes that there is a decreasing effect of output growth, but negatively and increasing effects of exchange rate and import dependence. Hence, those recent changes imply that this is caused by the change of the Chinese economy to be more trade dependent as well as we cannot deny the possibility of the external factors that play a role in CPI inflation, and its influence is gradually increasing in China.

Austrian Business Cycle Theory can shed light on the ways in which the current Chinese economic boom is unsustainable. On the one hand, government interventions, such as land monopolies, have raised costs for real estate developers. By limiting the availability of investment instruments and access to external markets, government interventions have created a strong demand for housing as a hedging tool. On the other hand, a loose monetary policy and artificially low interest rates have made the property market tempting for developers. Over-construction and over-consumption in the housing sector epitomise the capital structure analysis that Austrian economists regard as the core of their business cycle theory.

We employ a wavelet spectrum analysis to study globalization and business cycles in China and G7 countries. The co-movement synchronization between G7 countries and China is shown to have undergone frequent and large changes during our sample period. The co-movements for business-cycle frequencies are generally different from those for other frequencies. We find a significant relationship between the time-varying wavelet measure of synchronization and trade only for business-cycle frequencies. The co-movements at longer frequencies are negatively related to trade, so that the overall co-movements and trade tend not to be significantly related. [ABSTRACT FROM AUTHOR]

A small-scale New-Keynesian dynamic stochastic general equilibrium model is estimated by maximum likelihood method using quarterly data of China. Model specifications and parameter equalities between various competing model variants are addressed by formal statistical hypothesis tests, while implications for business cycle fluctuations are evaluated via a variance decomposition experiment, second-moments matching, and some out-of-sample forecast exercises. It is highlighted that both forward and backward components are important for the dynamics of output, inflation and real balances. The monetary authority will take a sufficient aggressive stance, with a significant lagged response, to the current inflation pressure, while leaving less attention to changes in aggregate output. Variance decomposition reveals that large percentages of variations in real and nominal variables are explained by the highly volatile preference shock and potential output shock, respectively. When nominal and real frictions as well as additional shocks are included, our estimated model overall can successfully reproduce the stylized facts of business cycles in the actual data of China and even frequently outperform those forecasts from an unconstrained VAR.

This paper documents important changes in the Chinese macroeconomic environment over the last three decades. The volatility of Chinese aggregate economic activities has fallen dramatically by nearly 60 per cent during its reform period, a phenomenon that coincides with the ' Great Moderation' that occurred in most industrialized economies. We employ a provincial panel-data method to investigate the driving forces of the increasing macroeconomic stability in China. We examine the empirical relationship between output volatility and various economic, policy, institutional, and demographic factors. Our results suggest that the acceleration of reform toward the market economy, which began around 1994, generally leads to a widespread output volatility reduction across Chinese provinces. Both state-owned enterprise reform and human capital accumulation are important determinants of output volatility since the mid-1990s; they play an important role in explaining the provincial differences on volatility reduction.

The major objectives of China's macroeconomic policy are to stabilize economic growth and inflation, which, in turn, are important factors determining key prices, such as the policy interest rate, the renminbi exchange rate and stock prices. In a framework that distinguishes different phases of the business cycle based on whether the current period's economic growth rate and inflation rate are above or below their 'normal' values, this paper analyzes the interaction among macroeconomic policy, economic growth and inflation in China since the Lehman crisis, and the implications for these key prices. The path of China's economy indicates that stimulus measures taken by the government during the recession phase and tightening measures implemented during the overheating phase have helped minimize the fluctuation over the business cycle. Our analysis shows that Chinese authorities tend to rely more on adjusting the exchange rate than the interest rate to stabilize the economy. Comparing with conditions at the time of the post-Lehman recession, the current slow pace of economic growth in China may reflect not only weakening demand, but also a lower potential growth rate associated with the arrival of the Lewis turning point.

Unlike in OECD countries, fluctuations in output growth in China are not straightforward in their interpretation. On the one hand, they reflect the business cycle, which results from shocks to aggregate demand. On the other hand, they also reflect the structural transformations that have accompanied China’s transition to a market economy. Demand shocks can be identified by virtue of the persistence of their impact. This paper decomposes the variance in provincial, regional, and national output growth according to its persistence characteristics. The results suggest that during the reform period, only a minority of output growth variance can be attributed to demand shocks and business cycle fluctuations. It is also found that there is substantial heterogeneity in the persistence characteristics of output growth across provinces. Implications of the findings for macroeconomic policy are discussed.

In responding to a view that attributes sharp downturns in the Chinese economy in late 2008 and early 2009 to the “collapse of external demand,” the present paper scrutinizes three relevant issues: How have large Chinese importers behaved in a demand-price setting? How have Chinese commodity imports and exports interacted in recent years? Did the downturns in China's export growth come earlier and were they deeper than those in Chinese import growth? All answers appear to suggest a conclusion contrary to the abovementioned view: sharp downturns in China's trade and economy during the recent global financial crisis were, to a large extent, caused by certain domestic factors, or by factors that should not be regarded as entirely “external.” Insomuch as globalization has advanced, a large economy like China's today faces new potential sources of macroeconomic disturbances, from inside and outside.

Friedman's plucking model of business fluctuations suggests that output cannot exceed an upper limit, but it is occasionally “plucked” downward below trends as a result of economic recessions. This paper investigates China's business fluctuations using quarterly real GDP data for the period 1978–2009. Our results show some evidence supporting Friedman's plucking model. We find that a ceiling effect of real output exists, and that negative asymmetric shocks significantly affect the transitory component, which captures the plucking downward behavior during the recession. The results also suggest that the basic asymmetric unobserved component model is not appropriate for directly modeling China's real output because the business cycle is inaccurately measured, but it works quite well when considering a structural break in the second quarter of 1992. The results reveal that although China's economy strengthened in the second quarter of 2009, it is essential for China's government to take further positive and effective measures to maintain sustainable development of the economy.

The paper investigates the relationship between changes in asset wealth and the trend movements of household consumption in urban China. Using the vector error correction cointegration model, we demonstrate that there is a unique long-run cointegrating relationship between household consumption, disposable income, financial wealth and housing wealth in urban China. We find that housing wealth is the only factor that restores the long-run equilibrium relationship when the cointegrated system is disturbed by an external shock. In addition, our permanent–transitory variance decomposition analysis indicates that nearly all variance in the movement of consumption is permanent, supporting the classical random walk hypothesis of consumption behavior. However, a large proportion of variance in the short-run movements of housing wealth is found to be transitory. [ABSTRACT FROM AUTHOR]

The paper attempts to evaluate the prospect of creating a currency union in the “Greater China” economic area. Despite of the political deadlock and military confrontation in the Taiwan Strait, the Greater China area has experienced rapid and spontaneous regional integration in the past decades as a result of increasingly cross-border trade, foreign direct investment (FDI), technology contracts, and other arrangements in accordance with changes in comparative advantage and industrial upgrading in these economies. In this study, we focus on the symmetry in shocks that is perceived as one of the major preconditions of a currency union. In contrast to the previous studies, we investigate the time-varying correlation of supply, REER and monetary shocks by using the Kalman filter technique to assess the dynamic changes in structural similarity and convergence among the Greater China economies. We also examine the costs of forming a currency union in the area due to the loss of monetary autonomy in each economy. Our results suggest that there is a rising structural symmetry between the Greater China economies, and this area has become increasingly a better candidate for a monetary union.
