Banking Sector Development and Energy Consumption in Nigeria: Exploring the Causal Relationship and its Implications

This study examines the causal relationship between banking sector development and energy consumption in Nigeria over the period 1971–2013 incorporating crude oil price and indicators of economic performance. An autoregressive distributed lag bounds testing approach to cointegration provides evidence of long‐run relationship among the variables. The long‐run and short‐run estimates suggest that a non‐linear inverted U‐shaped relationship exists between banking sector development and energy consumption in Nigeria, indicating that initially, energy consumption increases as the banking sector develops and then declines as the banking sector matures to generate efficiency in energy consumption. In addition, this study explores the direction of causality between the variables using the Toda–Yamamoto Granger causality test procedure. The results suggest that a unidirectional causality runs from crude oil price to banking sector development, from banking sector development to energy consumption and from energy consumption to economic growth. It may therefore be necessary for policy makers in Nigeria to incorporate banking sector development in the energy and sustainable economic policies.     

Causal Relationship between Domestic Savings and Economic Growth: Evidence from Seven African Countries

This paper utilizes cointegration and the vector error‐correction model (VECM) to explore the causal relationship between economic growth and growth rate of domestic savings for Congo, Côte d’Ivoire, Ghana, Kenya, South Africa, and Zambia. Specifically, three analyses were undertaken. First, the time series properties of economic growth and domestic savings were ascertained with the help of the augmented Dickey–Fuller unit root procedure. Second, the long‐run relationship between economic growth and growth rate of domestic savings was examined in the context of the Johansen and Juselius (1990) framework. Finally, a Granger‐causality test was undertaken to determine the direction of causality between economic growth and growth rate of domestic savings. The results indicate one order of integration [I(1)] for each of the series. The results of the cointegration tests suggest that there is a long‐run relationship between economic growth and growth rate of savings. The results from the Granger‐causality tests indicate that contrary to the conventional wisdom, economic growth prima facie causes growth rate of domestic savings for most of the countries under consideration.     

Re‐Visiting Financial Development and Economic Growth Nexus: The Role of Capitalization in Bangladesh

This paper revisits the relationship between financial development and economic growth in Bangladesh by incorporating trade openness in production function using quarter frequency data over the period of 1976‐2012. We applied combined Bayer–Hanck cointegration approach to examine cointegration among the series. Our empirical evidence suggests that development of financial sector facilitates economic growth but capitalization impedes it. In addition, trade openness stimulates economic growth. Labour is also positively linked to economic growth. The vector error correction model Granger causality results divulge that financial development causes real per capita gross domestic product (GDP) growth, and resultantly, real per capita GDP growth causes financial development in a Granger sense. The results also show that trade and labour Granger cause economic growth. The findings of the paper provide insights for policymakers to use financial development and trade openness as a tool for sustained economic growth in the long run. The paper also suggests policymakers to utilise capitalization in a way that is beneficial for economic growth of Bangladesh.     

Foreign Direct Investment and Trade: A Causality Analysis

In this article, we analyze the relationship between outward foreign direct investment (FDI) and exports, using Spanish quarterly data for the period 1977–1998, by means of Granger causality tests in a cointegration framework. Our results point to the existence of a relationship of complementarity between both variables, with Granger causality running in the short run from outward FDI to exports, and bilateral Granger causality in the long run.     

Electricity Consumption–Economic Growth–CO2 Emissions Nexus in Sub‐Saharan Africa: Evidence from Panel Cointegration

This study explores the causal relationship among electricity consumption, economic growth and CO₂ emissions for a group of 14 sub‐Sahara African (SSA) countries from 1980 to 2009 using panel cointegration and panel vector error correction modelling methods. The findings demonstrate that in the long run electricity consumption has a statistically significant positive impact on CO₂ emissions. The results also reveal that the inverted U‐shaped Environmental Kuznets Curve (EKC) hypothesis exists in the SSA countries' case. The panel causality tests indicate that there is short‐run unidirectional causality running from economic growth to CO₂ emissions and electricity consumption respectively. Simultaneously, there is long‐run bidirectional causality between electricity consumption and economic growth, electricity consumption and CO₂ emissions, economic growth and CO₂ emissions. Depending on the results, relevant policies can be initiated without negatively affecting economic growth.

Interest Rate Liberalization and Economic Growth in Zambia: A Dynamic Linkage

Abstract: This paper examines the dynamic impact of interest rate reforms on economic growth in Zambia—using two models in a stepwise fashion. In the first model, the efficacy of interest rate liberalization is examined by regressing the interest rate on the level of financial deepening. In the second model, the causal relationship between financial depth and economic growth is examined by incorporating savings as an intermittent variable in the bivariate setting, thereby creating a simple trivariate model. Using the cointegration‐based error correction model, the study finds strong support for the positive impact of interest rate liberalization on financial deepening. In addition, the study finds that financial deepening, which results from interest rate liberalization, Granger causes economic growth. The results apply irrespective of whether the causality is estimated in the short run or in the long run. Other results show that: (1) lagged financial depth leads to further financial deepening; (2) savings and economic growth Granger cause each other; and (3) financial development Granger causes savings in the long run.     

WAGNER'S LAW: AN ECONOMETRIC TEST FOR SOUTH AFRICA, 1960‐2006

The main objective for this paper is to test Wagner's law by analysing the causal relationships between real government expenditure and real income for South Africa for the period 1960‐2006. The paper tests the long‐run relationship between the two variables using the autoregressive distributive lag approach to cointegration suggested by Pesaran et al. We use the Granger non‐causality test procedure developed by Toda and Yamamoto, which uses a vector autoregression model to test for the causal link between the two. Evidence of cointegration is sufficient to establish a long‐run relationship between government expenditure and income. However, support for Wagner's law would require unidirectional causality from income to government expenditure. Therefore, cointegration should be seen as a necessary condition for Wagner's law, but not sufficient. This research does find a long‐run relationship between real per capita government expenditure and real per capita income. Results for the short‐run causality find bidirectional causality. On the basis of empirical results in this paper, one may tentatively conclude that Wagner's law finds no support in South Africa.     

EXPORT‐LED GROWTH HYPOTHESIS: FURTHER ECONOMETRIC EVIDENCE FROM SOUTH ASIA

This paper examines the export‐led growth (ELG) hypothesis for five South Asian countries through cointegration and multivariate Granger causality tests. Strong support for a long‐run relationship among exports, imports, and real output for all the countries except Sri Lanka were found. Feedback effects between exports and GDP for Bangladesh and Nepal and unidirectional causality from exports to output in the case of Pakistan were found. No causality between these variables was found for Sri Lanka and India, although for India GDP and exports did induce imports. A feedback effect between imports and GDP was also documented for Pakistan, Bangladesh, and Nepal, as well as unidirectional causality from imports to output growth for Sri Lanka. These and other findings are discussed from the standpoint of the export‐led growth hypothesis.

Analysis of the Interactive Linkages Between Gold Prices,Oil Prices,and Exchange Rate in India

This study investigates the co-movements and linkages among gold prices, oil prices, and Indian rupee–dollar exchange rates for the time span of 12 January 2004 to 30 April 2015 to investigate whether Indian economic policy-makers should detach financial policies from energy policies. Various econometrical methods such as Johansen’s cointegration test, vector autoregressive model, Granger causality test, and impulse response were used to explain the co-movements among the variables. We find that gold prices, oil prices, and rupee–dollar exchange rates stay substantially independent from each other, which denotes energy policies and financial policies must be detached.     

EXPORT AND ECONOMIC GROWTH IN NAMIBIA: A GRANGER CAUSALITY ANALYSIS

The purpose of this paper is to analyse the causality between exports and GDP of Namibia and to evaluate the relationship of these variables for the period 1970 to 2005. Time‐series econometric techniques (Granger causality and cointegration) are applied to test the hypothesis of a growth strategy led by exports. It tests whether export Granger causes GDP, or whether the causality runs from GDP to exports, or if there is bi‐directional causality between exports and GDP. The results revealed that exports Granger cause GDP and GDP per capita. This suggests that the export‐led growth strategy through various incentives has a positive influence on growth.     

Macroeconomic Variables and Stock Prices in Malaysia: An Empirical Analysis

The article investigates the dynamic interactions between seven macroeconomic variables and the stock prices for an emerging market, Malaysia, using cointegration and Granger causality tests. The results strongly suggest informational inefficiency in the Malaysian market. The bivariate analysis suggests cointegration between the stock prices and three macroeconomic variables – consumer prices, credit aggregates and official reserves. From bivariate error-correction models, we note the reactions of the stock prices to deviations from the long run equilibrium. These results are further strengthened when we extend the analysis to multivariate settings. We also note some evidence that the stock prices are Granger-caused by changes in the official reserves and exchange rates in the short run.     

Financial Development and Economic Growth in Sub‐Saharan African Countries: Evidence from Time Series Analysis

Abstract: This paper seeks to empirically explore the causal link between the level of financial development and economic growth in 13 sub‐Saharan African countries. The empirical investigation is carried out in a vector autoregression (VAR) framework based on the theory of cointegration and error‐correction representation of cointegrated variables. The results of the cointegration analysis provide evidence of the existence of a long‐run relationship between financial development and economic growth in almost all (12 out of 13) of the countries. With respect to the direction of long‐term causality, the results show that financial development plays a causal role on economic growth, again in eight of the countries. At the same time, evidence of bidirectional causal relationships is found in six countries. The findings imply that African countries can accelerate their economic growth by improving their financial systems.

Stock Markets,Banks and Long Run Economic Growth: A Panel Cointegration-Based Analysis

The aim of this paper is to investigate the long run relationship between the development of banks and stock markets and economic growth. We make use of a Johansen-based panel cointegration methodology allowing for cross-country dependence to test the number of cointegrating vectors among these three variables for 5 developing countries. In addition, we test the direction of potential causality between financial and economic development. Our results conclude to the existence of a single cointegrating vector between financial development and growth and of causality going from financial development to economic growth. We find little evidence of reverse causation as well as bi-directional causality. We interpret this as evidence supporting the significance of financial development for economic development although banks and stock markets may have different effects depending on the level of economic development.     

Public Revenue‐Expenditure Nexus in South Africa: Are there Asymmetries?

This paper re‐examines the government revenue and expenditure relationship in South Africa using Enders and Siklos' Threshold adjustment and Granger causality tests. The paper allows for structural breaks in the unit root and cointegration tests. The results indicate the absence of any asymmetries in both the threshold autoregression and momentum threshold autoregression specifications of adjustments in the South African's budgeting process. The estimated symmetric error‐correction models provide support for the fiscal synchronization hypothesis of government revenues and expenditures for long‐run and short‐run dynamic equilibrium. These findings indicate that the South African fiscal authorities should try to maintain or even improve the control of their fiscal policy instruments to sustain the prudent budgetary process.     

Export performance and economic growth causality: An empirical analysis

The cointegration and causal relationship between export growth and economic growth is investigated for the Nordic economies. On the basis of Johansen's technique and the augmented Granger causality tests, the evidence shows that these macroeconomic aggregates are causally related in the long run for each economy. Granger causality is unidirectional, running from economic growth to export growth in Denmark, and bidirectional in Finland, Norway, and Sweden. The established bidirectional causality suggests that the expansion of exports is an integral part of the economic growth process.

China's economic development: does exchange rate and FDI nexus matter?

This study aims to investigate the relationship between China's exchange rate, foreign direct investment (FDI) inflows, and economic development. We applied the bound testing approach on aggregate level data from 1981 to 2013. The results showed that the Chinese economy benefitted from a lower exchange rate over this period, and that there was a direct link between FDI inflows and economic development on an aggregate level both in the long and short run. The results of the Granger causality test identified a long‐ and short‐run association among these variables. The GMM estimations with dummies for financial crises and RMB exchange rate policy fluctuations also confirmed the growth enhancing impact of the exchange rate and FDI inflows. To promote sustainable economic development in the future, China should focus on improving the levels of domestic investment and human capital, as well as supervising the level of openness and capital controls.
