    Econometric Study Of Energy Consumption In Road Transport In Algeria
    (جامعة الوادي University of Eloued, 2025-03-31) Belkhiri, Aimad Edine
    The aim of this econometric study is to investigate energy consumption in the road transport sector in Algeria between 1980 and 2020, based on the ARDL model. Our aim was to identify the factors influencing energy consumption and assess their impact on this key sector of the economy. Variables such as the PARC vehicle fleet and fuel prices (PESS and PGAZ) were studied to identify important links and develop forecasting models. The main results showed significant coefficients for some variables, such as the car fleet (PARC), suggesting a positive influence on long-term energy consumption. As the number of vehicles increases, so does energy demand. In addition, model estimation (ECM) has highlighted the existence of a short-term adjustment towards long-term equilibrium, and confirms the importance of fuel prices as a factor influencing energy consumption in the transport sector. It is crucial to have these data in order to optimize and maintain sustainable energy use in the transport sector, thereby contributing to economic development and environmental protection.

    أثر بعض المتغيرات الاقتصادية الكلية على سعر الصرف الحقيقي في السعودية
    (جامعة الوادي University of Eloued, 2025-03-31) وافي ،ميلود; بوزيان، وسام; مناد، مروة فاطمة
    This study aims to measure the impact of the oil price, inflation rate, and economic growth on the real exchange rate in Saudi Arabia during the period from 1970 to 2022. The study relied on the autoregressive distributed lags (ARDL) model and analysis using the 13Eviews program. The study concluded that there is a cointegration between the variables of the study, and the most important result is that there is a direct relationship between the oil price and the exchange rate in the long run, where if the oil price rises by 1℅, the exchange rate in Saudi Arabia rises by 1.07%
