Each equation of the VEC model can be estimated using the OLS method.. 3.5 Granger Causality Test. The Granger causality test will be performed on the four series in the context of the VAR model or the VEC model. Engle and Granger (1987) argue that, if cointegration exists between two variables in the long run, there must be either unidirectional or bi-directional Granger causality between these two variables. Granger causality test is then conducted in the context of the VEC model.

The standard Granger causality test for causality between electricity consumption and GDP is based on the bivariate regression model, which has the following forms:. null hypothesis of “GDP does not granger- causal electricity consumption” is. If δi = 0 for all i l, electricity consumption does not affect GDP in the short-run. and if фi = 0 for all i l, GDP does not have causal effects on electricity consumption in the short- run.

He found that US dollar exchange rate, WTI and LLG have random walk trend and become stationary series after first difference I(1) in ADF unit root test. LLG has one-way leading relationship on US dollar exchange rate in granger causality test.. LLG has one-way leading relationship with USDX in Granger causality test.. Therefore, it uses ADF unit root test to test data series stationary, Johansen cointegration, Granger causality, impulse response, and forecast error variance decomposition.

The lag length of the VAR and VEC model are selected according to the Akaike or Schwartz criterion.. 3.6 Granger Causality Test. Granger causality sheds lights on the direction of the causality between time series. This causality can be measured based on the conceptualization of prediction developed by Granger (1988). In an essence, the Granger causality lays on the idea that the cause occurs before the consequence.

However, there is no evidence of causality running towards the exchange rate. The Dick-Panchenko non-parametric and nonlinear Granger causality test in a contrary to the linear Granger causality test showed a unidirectional nonlinear causality from exchange rate to stock price at 10% level, and from oil price to exchange rate at 1% and 10% levels respectively.

The Granger Causality Test was applied to find the causality between the variable and the results of the granger causality test shown in Table 8.. The Granger causality results indicate that oil prices, population and food import bill are non-granger causes of each other, while there is a unidirectional causality at 10% significance level running from Gross Domestic Product per capita to food import Bill..

The results of the Granger causality test show that there is bi-directional causality from FDI to economic growth and trade openness to economic growth.. Trade openness and foreign direct investment (FDI) have been well known as vital factors in stimulating the process of economic growth.

Abstract: To investigate the role of governance and economic growth at the provincial level, this study conducted the Granger causality test for a panel data of 60 provinces in Vietnam from 2006 to 2014 and found that there is an existence of bi-directional causality linkage between provincial competitiveness (hereafter we call “governance”) and economic growth.

This has caused an increase in CO 2 which rose from 30.3 million metric tons to 195.8 million metric tons between 1980 and 2008.Likewise, using the Johanesn-Juleius (JJ) cointegration test, VECM and the Granger causality test, Dar and Asif (2017) and Mirza and Kanwal (2017) reported that an increase in energy consumption will also lead to high CO 2 emissions in the economy in the long run and vice versa and bidirectional causality exists between them..

The results of the granger causality test also confirm the unidirectional causality running from trade openness and real GDP to energy demand. The results of the study have an important implication because if China wants to continue its trade liberalization policies then it must increase its energy production..

Results of the Granger causality test. The results of the Granger causality test are as follows: There is a one-way causal relation- ship from CO2 emissions, GDP value to FDI inflows at the significant level of 5% but there is no opposite side-effect in the short term. In the long run, the percentage of renewable energy consumption over total consumed energy illustrated a one-way cause-effect relationship with FDI.

The results for the λ trace and λ max statistics of the multivariate cointegration test are exhibited in Table 6. The Granger causality test is employed to further examine the causality relationship be- tween the VN-Index and the S&P 500 Index, the US Dollar - VN Dong exchange rates, gold prices, and crude oil prices. The results of the Granger causality tests are represented in Ta- ble 7.

The null hypothesis of the Granger causality test is that GROUP1 is influenced only by itself, and not by GROUP2. The following is an example of the CAUSAL statement. You specify the CAUSAL statement with the GROUP1= and GROUP2= options.

For the Granger causality test, the matrix C consists of zeros or ones and c is the zero vector. See Lütkepohl(1993) for more details of the Granger causality test.. The form of the VARX(p,s) model can be written as. The parameter estimates can be obtained by representing the general form of the multivariate linear model,. y D vec.Y 0 / ˇ D vec.B 0 / e D vec.E 0. The conditional least squares estimator of ˇ can be obtained by using the same method in a VAR(p) modeling.

The VARMAX procedure provides a Granger causality test to determine the Granger-causal relation- ships between two distinct groups of variables. It also provides the following:. impulse response function (or infinite order MA representation) decomposition of the predicted error covariances. roots of the characteristic functions for both the AR and MA parts to evaluate the proximity of the roots to the unit circle. contemporaneous relationships among the components of the vector time series.
