Prospects for the economy and foreign trade of Ethiopia: fore cast estimates based on mathematical modeling

The article presents a forecast assessment of the development of the national economy and foreign trade of Ethiopia until 2030, calculated by the authors on the basis of a mathematical and systematic analysis of macroeconomic processes and methods of modeling these processes usingthe Box-Jenkins model (ARIMA). Estimation method: the exact maximum likelihood method. The topic seems relevant due to Ethiopia's accession to the BRICS alliance from 2024. Therefore, it is important to predict possible trends in Ethiopia's economic and foreign trade development, their significance for the country itself, as well as their impact on the economic dynamics of other BRICS countries and the association as a whole. The study is updated taking into account the continued increase in global volatility and the emergence of new threats, including in Africa. The subject is trends in the economic development of Ethiopia as a member of the BRICS. The purpose of the article is to develop a scientifically based forecast of the development of the economy and foreign trade of Ethiopia in the medium term. The article identifies potential threats to the development of the Ethiopian economy. The statistical basis of the study was mainly data from the United Nations Conference on Trade and Development (UNCTAD). The results of the study can be used to understand the trends of socio-economic and foreign trade development of the country, adjust this development, as well as expand and enrich the theoretical concepts of the world economy. The research and author's calculations are based solely on the current circumstances and current realities, without taking into account any fundamental changes in the politics and economy of the country under study. The author's calculations and conclusions can be useful to economists, entrepreneurs, and researchers as a basis for their further practical and scientific activities.
