This technical assistance report documents the key phases of the scoping mission for the development of a macroeconomic model based on financial programming, conducted in Libreville from May 5 to 15, 2025, on behalf of the Ministry of Economy and Participations of Gabon. The mission undertook a comprehensive assessment of existing analytical tools and data quality, alongside delivering targeted training on financial programming and debt analysis. The exercise highlighted various areas to strengthen the current tools as well as organizational constraints to be addressed to improve performance. Building on these findings, a series of recommendations were formulated, endorsed by the authorities, and subsequently integrated into the project’s action plan. These recommendations propose a step-by-step strategy for the development of a customized macroeconomic model, fully integrated with a Debt Dynamics Tool (DDT), and supported by continuous capacity building and strengthened inter-institutional coordination, aimed at enhancing the robustness of economic analysis and fostering improved evidence-based decision-making processes.
