Causal relationship between energy consumption and GDP growth revisited: A dynamic panel data approach

This paper uses the panel data of energy consumption and GDP for 82 countries from 1972 to 2002. Based on the income levels defined by the World Bank, the data are divided into four categories: low income group, lower middle income group, upper middle income group, and high income group. We employ the GMM-SYS approach for the estimation of the panel VAR model in each of the four groups. Afterwards, the causal relationship between energy consumption and economic growth is tested and ascertained. We discover: (a) in the low income group, there exists no causal relationship between energy consumption and economic growth; (b) in the middle income groups (lower and upper middle income groups), economic growth leads energy consumption positively; (c) in the high income group countries, economic growth leads energy consumption negatively. After further in-depth analysis of energy related data, the results indicate that, in the high income group, there is a great environmental improvement as a result of more efficient energy use and reduction in the release of CO₂. However, in the upper middle income group countries, after the energy crisis, the energy efficiency declines and the release of CO₂ rises. Since there is no evidence indicating that energy consumption leads economic growth in any of the four income groups, a stronger energy conservation policy should be pursued in all countries.     

The causal relationship between financial development and economic growth in Africa

ABSTRACT

Previous empirical studies on the causal relationship between financial development and economic growth are not instructive given their failure to unearth the causality trend across the different time periods. Using a more recently developed and robust indicator of financial development, we revisit the causal relationship between financial development and economic growth within the framework of a frequency-domain spectral causality technique which allows the causality to vary across time. Using data from 47 African countries over the period 1980–2016, our findings largely suggest that, even though there is some evidence of demand-following, supply-leading and feedback hypotheses, for most part, we find strong support of neutrality hypothesis. Thus, financial development and economic growth at most frequency levels evolve independently. We infer that caution must be exercised in making general conclusions about the causal nexus between financial development and economic growth.     

Inclusive institutions and economic growth: comparative perspective and policy implications for China

ABSTRACT

This paper examines the empirical relationship between the presence of inclusive institutions and the pattern of economic growth in a cross-country setting. We find evidence that the presence of inclusive institutions, indicated by political democracy, positively affects consumption share. In turn, the increase of the latter in the preceding year is associated with a significantly higher rate of total factor productivity (TFP) growth. The link from democracy to TFP growth via consumption is stronger for countries of higher levels of income. These findings suggest that institutional inclusiveness may have become increasingly important for economic growth when the level of income rises. We also provide preliminary evidence that consumption may have facilitated productivity growth via the channels of increasing innovations and reducing social conflicts. The findings shed lights on the structural transformations toward a more inclusive and sustainable model of growth in China today.

How strong is the causal relationship between globalization and energy consumption in developed economies? A country-specific time-series and panel analysis

We examine the causal relationship between globalization, economic growth and energy consumption for 25 developed economies using both time series and panel data techniques for the period 1970–2014. Due to the presence of cross-sectional dependence in the panel (countries from Asia, North America, Western Europe and Oceania), we employ the cross-sectional augmented IPS test to ascertain unit root properties. The cointegration test results indicate the presence of a long-run association between globalization, economic growth and energy consumption. Long-run heterogeneous panel elasticities are estimated through the common correlated effects mean group estimator and the augmented mean group estimator. The empirical results reveal that, for most countries, globalization increases energy consumption. In the USA and UK, globalization is negatively correlated with energy consumption. The causality analysis indicates the presence of the globalization-driven energy consumption hypothesis. This empirical analysis suggests insightful policy guidelines for policy makers using globalization as an economic tool to utilize energy efficiently for sustainable economic development in the long run.     

Does urbanization increase pollutant emission and energy intensity? evidence from some Asian developing economies

This paper aims to investigate the effects of urbanization on pollutant emissions and energy intensity in selected Asian developing countries after controlling for the effects of disaggregated (renewable and non-renewable) energy consumption, trade liberalization, and economic growth. We use both linear and nonlinear panel data econometric techniques and employ recently introduced mean group estimation methods, allowing for heterogeneity and cross-sectional dependence. However, to check the robustness of our panel results, we also apply the autoregressive distributed lag (ARDL)-bound testing approach to country-level data. In addition, the relationship between affluence and CO₂ emissions is examined in the context of the Environmental Kuznets Curve (EKC) hypothesis. The estimation results identify the population, affluence, and non-renewable energy consumption as major factors in pollutant emissions in Asian countries. However, the results of the EKC hypothesis show that when countries achieve a certain level of economic growth, their emissions tend to decline. Whereas nonlinear results show that renewable energy, urbanization, and trade liberalization reduce emissions, linear estimations do not confirm these outcomes. Thus, substitution of non-renewable for renewable energy consumption, cautious and planned urbanization programs and more liberal trading regimes may be viable options for sustainable growth of these developing Asian economies.     

Predictability within the energy consumption–economic growth nexus: Some evidence from income and regional groups

In re-examining the nexus between energy consumption and economic growth through the predictability framework, we adopt a panel data predictive regression model to examine the possibility of growth, conservative, feedback, or neutrality hypotheses for 135 countries. A predictive regression model is fitted to panels of countries on the basis of location and level of economic development. Findings suggest strong support for the neutrality hypothesis. A developing economy panel (90 countries) favours the conservative hypothesis, although a panel of 32 lower middle-income countries suggests that energy consumption per capita predicts real GDP per capita. These forecasts could provide future policy directions.     

Is education important in assessing the impact of institutions on economic growth in emerging economies?

ABSTRACT

In this article, we empirically revise the hypothesis that institutions cause economic growth for emerging countries starting from a theoretical model. Our sample consists of 21 countries covering different zones: European Emerging, Asia Pacific Emerging, Latin America, Middle-East and Africa while the status advanced versus secondary emerging countries based on FTSE (Financial Times Stock Exchange) classification is accounted for. The period analysed is 1995–2014. The methodology is based on System GMM estimator of Arellano-Bover and Blundell-Bond for dynamic panel data. Empirical findings suggest that only variables such as voice and accountability and government effectiveness have a significant positive impact on economic growth rates of the analysed countries. In the presence of control variables, i.e. trade and government final consumption, results are robust. Results remain robust for countries that have a high level of government expenditure on tertiary education which proves the role of education in assessing the impact of institutions on economic growth.     

经济发展的基本因素:一个文献综述

本文对经济发展与增长的基本因素的四种看法或假说进行了回顾与梳理,包括运气(多重均衡)假说、文化与宗教信仰假说、地理与疾病假说以及制度和政策假说。这四种因素都会通过影响资本积累和技术进步等直接因素,从而影响经济发展与增长。然而,运气、文化和地理都不足以产生持续和巨大的人均收入的跨国差异,无法解释世界各国经济发展的历史。相反,制度和政策假说能很好地解释各国人均收入差异以及1500年以来世界财富的逆转。越来越多的经济学家相信,制度和政策是经济发展与增长的主要的基本因素。本文把重点放在有关制度和政策作为经济发展的根本原因的文献上,总结了有关经济制度和政治制度内生的文献,并进行了结论性述评。     

Does financial development reduce CO2 emissions in Malaysian economy? A time series analysis

This study deals with the question whether financial development reduces CO₂ emissions or not in case of Malaysia. For this purpose, we apply the bounds testing approach to cointegration between the variables. We establish the presence of significant long-run relationships between CO₂ emissions, financial development, energy consumption and economic growth. The empirical evidence also indicates that financial development reduces CO₂ emissions. Energy consumption and economic growth add in CO₂ emissions. The Granger causality analysis reveals the feedback hypothesis between financial development and CO₂ emissions, energy consumption and CO₂ emissions and, between CO₂ emissions and economic growth.     

Do oil consumption and economic growth intensify environmental degradation? Evidence from developing economies

The purpose of this article is to empirically investigate the impact of economic growth, oil consumption, financial development, industrialization and trade openness on carbon dioxide (CO₂) emissions, particularly in relation to major oil-consuming developing economies. This study utilizes annual data from 1980 to 2012 on a panel of 18 developing countries. Our empirical analysis employs robust panel cointegration tests and a vector error correction model (VECM) framework. The empirical results of three panel cointegration models suggest that there is a significant long-run equilibrium relationship among economic growth, oil consumption, financial development, industrialization, trade openness and CO₂ emissions. Similarly, results from VECMs show that economic growth, oil consumption and industrialization have a short-run dynamic bidirectional feedback relationship with CO₂ emissions. Long-run (error-correction term) bidirectional causalities are found among CO₂ emissions, economic growth, oil consumption, financial development and trade openness. Our results confirm that economic growth and oil consumption have a significant impact on the CO₂ emissions in developing economies. Hence, the findings of this study have important policy implications for mitigating CO₂ emissions and offering sustainable economic development.     

Long run time series tests of constant steady-state growth

We propose a new methodology to study the stability of steady-state growth. Long-run GDP per capita can be characterized by: (1) the linear trend hypothesis, where there are no long-run changes in GDP levels or growth rates, (2) the level shift hypothesis, where there are long-run level shifts, but not changes in growth rates, and (3) the growth shift hypothesis, where there are long-run changes in both GDP levels and growth rates. We formally test these hypotheses using time series techniques with over 139 years of data. The results are not favorable to the hypothesis of constant steady-state growth. While we find evidence supporting the linear trend hypothesis for the United States and Canada and the level shift hypothesis for three additional OECD countries, the growth shift hypothesis is supported for seven OECD and four Asian countries. The results are not driven by transition dynamics.     

Social security expenditure and GDP in OECD countries: A cointegrated panel analysis

Abstract

Using panel data unit root tests and panel cointegration tests, as well as estimation techniques appropriate for heterogeneous panels such as the full modified OLS, this paper re-examines the long-run co-movement and the causal relationship between GDP and social security expenditure in a bivariate model, employing data on 25 OECD countries from 1980 to 2001. Our cointegration test results show strong evidence in favour of the existence of a long-run equilibrium cointegrating relationship between GDP and social security expenditure after allowing for a heterogeneous country effect. Regarding the panel-based error correction model, we find that GDP and social security expenditure lack short-run causality, but reveal the existence of long-run bidirectional causality. This shows that, in the long run, economic growth must be based on a social welfare policy that should be carried out, and economic growth can facilitate contiguous development in a social welfare policy. Lastly, we also provide evidence to support that social security expenditure can affect growth through the savings and human capital accumulation in OECD countries.     

Foreign Direct Investment,Financial Development and Their Impact on the GDP Growth in Low-income Countries

ABSTRACT

This essay empirically studies the effects and causal links between foreign direct investment (FDI), financial development (FD) and economic growth. The sample consists of the main economies of low-income countries and the study covers the period 1990–2015. The results of the estimate show that, under certain specific economic conditions, FDI affects positively the level of long-term economic growth; it thus makes it possible to improve the economic situation of these countries. Using Johansen’s cointegration technique, the results find that FD; FDI and GDP growth are cointegrated, that shows the pursuit of the long-term equilibrium relationship between them. The error correction model confirms the existence of a double causal relationship between FDI and GDP growth, and between FD and FDI and between GDP growth and FD.     

Dimensions and Determinants of Financialisation: Comparing OECD Countries since 1997

ABSTRACT

The financialisation literature has grown over the past decades. Despite a generally accepted definition, financialisation has been used to describe different phenomena. We distinguish between financialisation of non-financial companies, households and the financial sector and use activity and vulnerability measures. We identify seven financialisation hypotheses in the literature and empirically investigate them in a cross-country analysis for 17 OECD countries and two time periods, 1997–2007 as well as 2008–17. We find different financialisation measures are only weakly correlated, suggesting the existence of distinct financialisation processes. There is strong evidence that financialisation is linked to asset price inflation and correlated with a debt-driven demand regime. Financial deregulation encourages financialisation. There is limited evidence that market-based financial systems are more financialised. Foreign financial inflows do not seem a main driver. We do not find indication that an investment slowdown precedes financialisation. Our findings suggest financialisation should be understood as a variegated process, playing out differently across economic sectors and countries.     

Unit root and trend breaks in per capita output: evidence from sub-Saharan African countries

This article examines the nonstationary properties of per capita real output in 28 sub-Saharan African (SSA) countries, covering the period 1960–2014. The sequential testing approach proposed by Kejriwal and Lopez (2013, Econometric Reviews 32(8), 892–927) is used to categorize SSA countries into growth shift, level shift and linear trend hypotheses based on the presence or not of breaks in slope and/or level of the trend function. The break dates are associated to major historical or economic events such as sociopolitical crisis, commodity price fluctuations on international market, the discovery and the exploitation of mineral deposits or unfavourable environmental and climatic conditions. The empirical evidences of appropriate unit root tests fail to reject the unit root hypothesis in all the countries, suggesting that a shock would have a permanent effect on growth process, and stabilization policies may be implemented in dealing with income fluctuations.     

Export-led Growth in South Asia: A Panel Cointegration Analysis

Abstract

In this paper, we attempt to examine the export-led and manufacturing export-led growth hypothesis for four South Asian Countries; namely, India, Pakistan, Bangladesh and Sri Lanka, using Pedroni’s panel cointegration technique for the period 1980–2002. In this context we estimate growth accounting equations to investigate the impact of exports, manufacturing exports and other important physical and human capital variables on both total GDP and non-export GDP. The study finds long-run equilibrium relationship between GDP (and non-export GDP) and exports along with other variables supporting export-led growth hypothesis. The results also substantiate the existence of manufacturing export-led growth hypothesis. Further, we find that export, fixed capital formation, public expenditure on health and education have statistically significant coefficients re-emphasizing the importance of these variables for higher economic growth.     

The causal relationship between natural gas consumption and economic growth: evidence from the G7 countries

This article re-examines the nature of the causality between natural gas consumption and economic growth in G7 countries over the period from 1965 to 2011. We employ the Granger causality procedure proposed by Emirmahmutoglu and Kose (2011) which takes into account cross-sectional dependency and heterogeneity across countries. Our overall empirical results support the neutrality hypothesis for the panel while the individual country results confirm the same result with the exception of the case of UK, where the conservation hypothesis is confirmed, showing that GDP causes natural gas consumption in the country. These results make policies that promote the consumption of natural gas risk-free with regard to their effects to the economic growth and development levels.     

A multi-factor efficiency perspective to the relationships among world GDP, energy consumption and carbon dioxide emissions

Most of the research articles on climate change study the relationships between economic growth, and, carbon dioxide (CO₂) emission or energy consumption separately for analyzing the impacts of economic growth and energy consumption on global carbon dioxide emissions. In this paper, the linkages among CO₂ emissions, Gross Domestic Product (GDP) growth and energy consumption are studied simultaneously using Data Envelopment Analysis (DEA). The time period considered for the study is 1980-2001. The results show that world in the year 1980 was the most efficient in achieving the highest economic growth, emitting least carbon dioxide for a given level of energy consumption for that year. The efficiency index reduced in the next 8 years, fluctuated with a declining trend for the next 7 years, and began to rise from 1996 till 2001. The model is further extended in this paper for technology forecasting to identify the links between energy consumption and carbon dioxide emissions for achieving projected levels of GDP under two different assumptions on efficiency index. It has been identified using the forecasting model that, when the carbon dioxide emissions are restricted to the levels emitted in the year 1990 and when the efficiency index for the year 2025 is assumed to be at the level registered for the year 1980 (highest value), the non-fossil energy consumption needed to meet the GDP level projected for 2025 will be much smaller (35.46 quadrillion Btu for the reference GDP) than the values actually recorded in the year 1990 (44.59). However, the non-fossil energy consumption in 2025 (118.8) increases much more than the actual recorded in the year 1990 when the efficiency index in 2025 is assumed to be at the level registered for the year 1990.     

Financial Deepening and Economic Growth in Gulf Cooperation Council Countries

Abstract

The goal of this study is to investigate the causal relationship between financial development and economic growth in Gulf Cooperation Council (GCC) countries, i.e. Bahrain, Oman, Kuwait, Qatar, United Arab Emirates and Saudi Arabia, over the period 1980–2012. We employ panel unit root tests, and Error Correction Model and cointegration techniques to detect long-run and short-run causalities between the variables used in our study. The overall empirical results reveal that the financial sector development contributes significantly to economic growth in the GCC countries. Our results could be of great interest for policymakers since the financial sector could play a crucial role in lowering the dependency of the governments to oil revenues and could contribute significantly to spur economic growth.     

The effects of fiscal consolidations on the composition of government spending

ABSTRACT

In response to increasing debt paths, governments often implement fiscal consolidation programs. This paper studies the impact of these programs on the composition of government spending. System-GMM estimations performed on a sample of 53 developed and emerging countries over 1980–2011 reveal that fiscal consolidations significantly reduce the government investment-to-consumption ratio, i.e. a composition effect. Robust to a wide set of tests, including when using the narrative approach to identify fiscal consolidations, this significantly stronger contraction of government investment with respect to government consumption is at work particularly when debt is high and in the low phase of the economic cycle. Therefore, in such contexts, fiscal consolidations aimed at short-run stabilization may hurt the economy in the long-run through their detrimental effect on public investment, calling for a reflection upon how they could be re-designed to allow avoiding such undesirable consequences.
