Abstract

Research background: The aim of this paper is to examine the long run relationship among oil prices and the Algerian Dinar exchange rate over the period January 1995–February 2020 in Algeria as one of the most important oil-exporting countries and one of the OPEC members.

Purpose: This study investigated the co-integration relationship between oil prices and exchange rate in Algeria by testing the long-run relationship between the two variables and their positive and negative shocks.

Research methodology: the study applied both the traditional co-integration analysis using Engle-Granger, Phillips-Ouliaris and Johansen-Juselius tests and the hidden co-integration presented by Granger and Yoon (2002).

Results: The results revealed that there is no evidence of a co-movement and linkage between oil prices and exchange rate in Algeria over the period of study neither with the original series nor between the cumulative components whatever the dependent variable.

Novelty: This paper fills in the missing link between the Algerian Dinar exchange rate and oil prices especially with the absence of the hidden co-integration analysis in the case of Algeria and most of the developing countries. To deal with the oil shocks according to Apergis and Miller (2007) and Narayan and Gupta (2015) studies where when they suggested distinguishing between the negative and positive oil price shocks because the asymmetric effect on the macroeconomic variables.

Abstract
The aim of this paper is to examine the relationship between money supply, inflation rate, and economic growth in the context of Algeria, using various econometric procedures as co-integration without and with structural breaks in addition to three different ways of causality test for the period 1970-2018, the results confirm the long-run relationship between the variables with more than three structural breaks, but with the absence of the effects of money supply and inflation rate on economic growth both in short run and long run terms, on the other hand, the causality results confirmed the existence of hidden causalities among the variables running from the cumulative components not from the natural series, and all the results support the Monetarist view of inflation though the absence of any effect of money supply on economic growth.

Abstract

Research background
This paper examines the existence of Okun's law in Algeria over the period of 1970–2020 using both the gap and differences model.


Purpose
The main objective of this paper is to econometrically examine, explore and test the nexus among unemployment rate and economic growth, in order to have a clear explanation about unemployment in Algeria.


Research methodology
Firstly, the Kapetanios unit root test and Maki cointegration test are employed for the gap model to deal with the structural breaks than the estimation of the coefficients in this case, secondly, the quantile regression is used for the differences model; finally, three categories of causality tests are used in this research.


Results
The findings revealed that unemployment rates are not affected by output over the period of study both in the gap and differences model. Hence, Okun's law is not held in Algeria.


Novelty
The study focused on Okun's law in different ways. This latter carries out structural breaks in both the unit root and co-integration analysis. On the other hand, the study uses the quantile regression for the first time in the examination of Okun's law. In the same line of thought, this research introduces an asymmetric analysis in the Maki cointegration and quantile regression.
