The article presents a macro-econometric model designed for African economies with limited resources, focusing on Rwanda. The model includes 107 equations to analyze various economic factors and predict future trends. By using historical data from 1960 to 2009, the researchers successfully replicated past values and forecasted key economic indicators from 2010 to 2015. The model can assist policymakers in budgeting, forecasting, and analyzing macroeconomic policies. Additionally, simulations were conducted to assess the impact of policy changes and external shocks. This model provides a practical framework for developing similar models across Africa.
