Using the Mixed Data Sampling (MIDAS) model to study the impact of oil prices on economic growth in Algeria during the period 1990-2021

Omeyr CHELOUFI — 2024-12-16

This study aimed to determine the impact of monthly oil price fluctuations on the annual economic growth rates in Algeria during the period 1990-2021 using the (MIDAS) model. Among the most important findings of the study is that annual economic growth in Algeria is positively affected by the monthly changes in international oil prices. The study also found that MIDAS models have a great predictive ability, allowing researchers to utilize all available information for high-frequency variables, instead of using annual average values that lose a lot of information. These models also help avoid converting low-frequency variables to match high-frequency variables, reducing econometric issues in model diagnostics and ensuring greater accuracy in results.

The reality of Sharia supervision and auditing in the Islamic windows of traditional banks in Algeria

Sofiane Bennaiche — 2024-12-16

This study aimed to understand the mechanisms of Sharia supervision and auditing in Islamic windows of conventional banks in Algeria. The descriptive analytical approach was adopted to examine the mechanisms of Sharia supervision and auditing.

In conclusion, the Sharia Supervisory Board in the Housing Bank issues fatwas following the National Fatwa Authority for Islamic Financial Industry, which emanates from the Supreme Islamic Council for Fatwa. We also concluded that the importance of having a Sharia auditor in the bank is no less significant than having a Sharia Supervisory Board. Therefore, appointing a Sharia auditor alongside the Sharia Supervisory Board is necessary, while granting them full independence.

The impact of Non-Oil exports on economic growth under the trade openness policy in Algeria For the Period 1990-2022 using ARDL model

hadia belghit — 2024-12-16

This paper aims to study the impact of non-oil exports on economic growth for the period 1990-2022, which witnessed Algeria moving towards liberalizing foreign trade, by measuring the impact of non-oil exports, the trade openness index, the exchange rate, and foreign direct investment as independent variables on Economic growth as a dependent variable, based on the autoregressive model of distributed time gaps ARDL.

The results showed a positive relationship in both long and short term between economic growth and non-oil exports, the trade openness index, and foreign investment, and an inverse relationship in the two terms between the exchange rate and economic growth. In general, it became clear that promoting non-oil exports contributes greatly to raising economic growth rates.

Estimation of Technical Reserves in Automobile Insurance Using Deterministic and Stochastic Methods

Kamilia BELLAL — 2024-12-16

Insurance companies bear the responsibility of maintaining their financial stability on an ongoing basis. One of the most significant challenges they face in this regard is the inaccuracy of technical reserve estimates for outstanding claims. For this reason, numerous research studies have focused on developing methods to improve the accuracy of these estimates. In this paper, we will present and apply several methods for calculating technical reserve provisions, whether deterministic or stochastic, such as the chain ladder method, the Mack method, the bootstrap method, and generalized linear models (GLMs). These statistical and analytical methods will be applied to a dataset of bodily injury claims in the civil liability arising from automobile accidents, covering the period from 2012 to 2022, and issued by one of the leading insurance companies in the Algerian market. Each method will be described and implemented to provide more accurate reserve estimates. Finally, we will compare the results obtained from each of these methods.

Transforming Oil and Gas Operations with GIS: Insights from the Sonatrach SOD Project

Rachid Yassine AKKOUCHE — 2024-12-16

This study examines the implementation and impact of Geographic Information Systems (GIS) in the oil and gas industry, focusing on the Smart Oil Data (SOD) project at Sonatrach, Algeria's national Oil and Gas company. As the energy sector undergoes rapid digital transformation, GIS has emerged as a tool for optimizing operations, enhancing decision-making, and addressing environmental concerns. The research employs a case study approach to analyze Sonatrach's experience with SOD, an integrated GIS solution built on ESRI's platform. The study investigates how GIS technologies are applied across the upstream, midstream, and downstream segments, and in Health, Safety, and Environment management. It also explores the challenges of implementing such a system, including data standardization, organizational change management, and integrating innovation and renewable energy initiatives. Findings show that the SOD project significantly improved Sonatrach's operational efficiency, data management, and strategic planning. However, the implementation underscored the need for robust change management strategies and continuous innovation.
