LONG RUN RELATIONSHIP BETWEEN OIL PRICE SHOCKS, EXCHANGE RATE VOLATILITY AND ECONOMIC GROWTH IN NIGERIA

The paper examined the long run relationship between oil price shock, exchange rate volatility and economic growth in Nigeria over the period 1980-2019. The study employed the Johansen Vector Autoregression (VAR)-based cointegration technique model to examine the sensitivity of real economic growth to changes in oil prices and real exchange rate volatility in the long-run while the short run dynamics was checked using a vector error correction model. The result from the Granger causality test suggests that there is causality between oil price, exchange rate and GDP. The results from Johansen cointegration test indicate there exist a long-run equilibrium relationship among the variables. Findings further show that oil price shock and appreciation in the level of exchange rate exert positive impact on real economic growth in Nigeria. The paper therefore recommends greater diversification of the economy through investment in key productive sectors of the economy using income from the crude oil export to guard against the vicissitude of oil price shock and exchange rate volatility.

Oil price shock in the US and the euro area – evidence from the shadow rate and the term premium

The aim of this article is to investigate the consequences of oil price changes for the economy of the US and the euro area. Oil price transmission channel is assessed using Granger causalities and structural vector autoregressive (VAR) specifications (applying the Cholesky factorization and the restrictions following the method of Blanchard and Quah). The conventional oil price transmission channel is extended by a shadow policy rate and term premium, as the importance of both indicators has been growing rapidly in recent years. The results confirm that the oil price shock is not negligible in the aftermath of the Global Financial Crisis and in the subsequent period of monetary policy normalization. The findings are confirmed by the outcomes of the Bayesian VAR specification with sign restrictions. The consequences of changes in oil prices have significantly grown since the introduction of unconventional monetary instruments. The magnitude of the response of industrial production, price level and shadow interest rate to the oil price shock is strongest in the period corresponding to the unconventional monetary policy. In many cases, however, the reaction is short-lived. The conventional instrument (policy rate) in the euro area has still not been sufficient to stabilize the economy in the recent period of monetary policy normalization in the US.

South Sudan may struggle to attract oil investment

Significance Crude oil is central to South Sudan’s economy, providing between 80% and 90% of government revenue and almost all export earnings. Last year’s oil price shock hit the economy hard and prompted two disbursements by the IMF under the Rapid Credit Facility (RCF) in November 2020 and April 2021. Impacts Net foreign direct investment (FDI) will turn positive in fiscal year (FY) 2020/21, following three years of outflows. The central bank’s weekly foreign exchange auctions will continue to reduce the gap between the official and parallel market rates. Following a contraction of around 4%, GDP is expected to grow modestly at 2-3% in FY 2021/22 and FY 2022/23.

Crude Oil Price Shock and the Nigerian Stock Market Performance in the Face of Covid-19 Pandemic Evidence from ARDL & Granger Causality Approach

The study examined empirically the linear relationship between crude oil price shock and the Nigerian stock market performance, with the main objective of ascertaining the impact of the recent sharp decline in crude oil prices on stock market performance in the face of the global socio-economic challenge posed by COVID-19 pandemic. It used monthly time series data from the central bank of Nigeria (CBN) website (www.cbn.gov.ng) from 2017-2020 This period was chosen to capture the effects of changes in oil price on the performance of the Nigerian stock market within the context of the global economic challenges due to the COVID-19 pandemic. The auto-regressive distributed lag ARDL approach has been applied in the model specification and data analysis for the study. The results of the ARDL in both the short and long run revealed that the recent crude oil price shock has a significant impact on stock market performance in Nigeria. The results of the granger causality test also reveal a unidirectional causality from crude oil price to stock market performance with a piece of evidence from the current decline of global crude oil prices from December 2019 to April 2020. The study, therefore, suggests the need for the Nigerian capital market to continue to pursue with vigor the implementation of the capital market master plan in the hope that a more developed capital market should be able to absorb external shocks such as those arising from crude oil price fluctuations.

Oil and Mortality

This paper investigates the impacts of a large and exogenous oil price shock in December 1973 on mortality rates of the major oil producer nations of the Middle East and North Africa. We use longitudinal data from 1960 to 2014 and we apply the difference-in-differences approach to investigate the main question of the research. Our findings show that the oil price shock did not lead to higher GDP per capita, but it did lead to lower mortality. These findings are puzzling. A possible explanation is that the oil price shock allowed for higher spending on publicly funded health care. We find a positive impact of the oil price increase on the number of hospital beds which perhaps suggests that higher oil revenues increased spending on public health and that possibly decreased mortality.

The Effect of Oil Price Shock and Inflation on Stock Returns: A Comparative Study on ASEAN-3

This study aims to examine the effect of the WTI type oil price shock and inflation on stock returns from the ASEAN-3 capital markets, namely Indonesia, Thailand, and Philippines. The data used are monthly data from 2015 to 2019. The data analysis technique used is multiple linear regression. The results showed that oil price shocks had a significant positive effect on stock returns on the JASICA Mining index and the SET Resources index, but had no significant effect on the PSE Mining and Oil index. Furthermore, inflation had a significant positive effect on stock returns of Indonesia seen from the JASICA Mining index. Whereas, inflation had no significant effect on the SET Resources index of Thailand and the PSE Mining and Oil stock index of Philippines. Keywords: Oil price shock, Inflation, Stock return

Monitoring Cointegrating Polynomial Regressions: Theory and Application to the Environmental Kuznets Curves for Carbon and Sulfur Dioxide Emissions

This paper develops residual-based monitoring procedures for cointegrating polynomial regressions (CPRs), i.e., regression models including deterministic variables and integrated processes, as well as integer powers, of integrated processes as regressors. The regressors are allowed to be endogenous, and the stationary errors are allowed to be serially correlated. We consider five variants of monitoring statistics and develop the results for three modified least squares estimators for the parameters of the CPRs. The simulations show that using the combination of self-normalization and a moving window leads to the best performance. We use the developed monitoring statistics to assess the structural stability of environmental Kuznets curves (EKCs) for both CO2 and SO2 emissions for twelve industrialized countries since the first oil price shock.

The macroeconomic effects of increase and decrease in oil prices: evidences of asymmetric effects from India

Purpose The purpose of this paper is to assess whether oil price shocks emanating from oil price increase and decrease have a different impact on the macroeconomic activity. Design/methodology/approach This study conducts the empirical analysis using structural vector auto-regressive model on Indian data for the period from 1996 to 2017. This paper uses four key macroeconomic variables, namely, real gross domestic product (GDP), the real rate of interest, real money supply, wholesale price index inflation and various linear and non-linear measures of oil price shock. Findings Empirical results confirm that oil price shock has a significant impact on various macroeconomic variables used in the study. Specifically, shocks emanating from a decline in oil price have a stronger positive impact on real GDP, whereas, a shock due to the rise in oil price has a weaker negative impact on real GDP. Impulse responses confirm that shocks due to a decline in oil prices are long-lasting compared to similar shocks due to a rise in oil prices. Therefore, this study concludes that the macroeconomic impact of oil price shock is asymmetric in India. Originality/value This paper adds the following new insights: First, this paper presents a distinct relationship between the growth rate of oil price and GDP during increasing and decreasing phases of oil price to drive home the case for this study. Second, India has adopted crucial administrative initiatives such as deregulation of the market for petroleum products and the promotion of renewable energy during the study period. Finally, previous studies have revealed specific behavioral and economic features of people in India with respect to the demand for petroleum products. In light of these factors, this paper based on Indian experience would be justified.
