a r t i c l e i n f o JEL classification: F1 F4 Q43 N75 Keywords: Oil price shock Trade balance VAR Granger non-causality test Gregory-Hansen cointegration test This study aims to examine whether a large part of the variability of trade balances and their oil and non-oil components is associated with oil price fluctuations. The long-run causality running from oil price to overall, oil and non-o...

In 2016, the Kingdom of Saudi Arabia (KSA) announced its Vision 2030 strategic plan incorporating major changes to the economic structure of the country, in­ cluding an intention to deploy 9.5 GW of renewable energy in an effort to reduce the penetration of oil in the electricity generation system. This paper assesses the macroeconomic impact of such changes in the KSA, coupled with reductions ...

The relationship between exports, imports and economic growth of Ethiopia has been investigated in this paper for the period 1981-2018 by using annual data from World Bank. For analysis, Vector Auto Regressive Model, Johansen co-integration analysis Granger-Causality tests were implemented. outcome reveals that there is no relation Ethiopia. Conversely, we found a strong evidence bidirectional ...

In the last decades, the problem of perforation damage has been considered as the major factor for the reduction of oil productivity. Underbalance perforation is considered as one of the best means to minimize or overcome this problem. By maintaining wellbore pressure lower than formation pressure, perforation damage could be minimize or eliminated. This can be achieved by the use of nontraditi...

This paper uses the gravity-model approach to deal with two issues related to economic integration. The first concern is to analyse the impact on FDI stocks of specific variables denoting the will to integrate, and their relative impact on exports. Variables considered include tariffs, non-tariff barriers and exchange rate variability. The results show that the widespread opinion – and theoreti...
