Environmental Taxes and Their Role in Supporting the Path of Sustainable Growth: European Countries as a Model for the Period
This study examines how environmental tax revenues have evolved in five European countries from 2010 to 2023, considering both their absolute values and their share of GDP. While environmental taxation has attracted increasing attention in Europe, prior studies have rarely analyzed the long-term trajectory of these revenues, leaving a gap in understanding their significance within fiscal policies and sustainable growth strategies. Using a descriptive-analytical approach, the study finds that revenues have steadily increased in absolute terms, whereas their proportion of GDP has remained stable or declined slightly, highlighting their integration into broader sustainable growth objectives.

Forecasting the exchange rate of the Algerian dinar against the US dollar using an Autoregressive Model, Integrated Moving Averages, and Artificial Neural Networks – a comparative study
This research paper aims to evaluate and compare the predictive performance of two models for forecasting the Algerian dinar exchange rate against the US dollar: the Autoregressive Integrated Moving Average (ARIMA) model, and the Artificial Neural Network (NAR-ANN) model, To achieve this objective, monthly data (01/2000 to 12/2025) was used. This data was divided into two sets: a training set covering the first 281 months for estimating the two models, and a test set covering the last 31 months for testing and comparing them. The applied results, comparing the predictive performance of the two models using prediction accuracy criteria, showed that the NAR-ANN model outperformed the ARIMA model in predicting the Algerian dinar exchange rate against the US dollar.

Testing Frankel's Monetary Model in Algeria Evidence from 1995 to 2023
This study analyzes short- and long-term determinants of exchange rate movements using the ARDL model. Based on monetary and output theories, it considers money supply, income differentials, and interest rate spreads. Results confirm a stable long-run cointegration: domestic money growth depreciates the currency, while higher income strengthens it. Interest rate differentials affect short-term fluctuations but not the long run. The error correction term shows rapid adjustment to equilibrium. Short-term dynamics also capture lagged effects of money and income. Findings support uncovered interest parity. Diagnostic tests validate model stability, stressing the importance of prudent monetary policy and balanced growth for exchange rate stability. Jel Classification Codes: F31, E52, E41, C32.
