Intervals of Uncertainty of Economy

A.A. Tavadyan developed interval methods for researching economic indicators under uncertainty. He formulated the relationship between uncertainties and the minimum interval of uncertainty, the expanding uncertainty band effect, and the sensitivity thresholds of economic indicators. He presented the principles of systematizing and predicting economic indicators. The author's developed concept of studying economic processes is presented in the following books: "Systemology of Economic Categories" (M.Nauka), "Intervals of Economic Uncertainty" (M.Nauka), "Uncertainty Bands and Economic Variability" (M. Flinta), and "Uncertainty Bands: A Guide to Predicting and Regulating Economic Processes" (London, Anthem Press).

Integration studies
The integration research under the leadership of A.A. Tavadyan was carried out in 2013 in Armenia. The study focused on the economic effects of Armenia in the Eurasian Economic Union and other integration processes. The migration and transfer flows, dynamic and structure of GDP, and trade volume under different scenarios of integration processes in Armenia were estimated through economic-mathematical methods. The results of the research were published in a report in English and Russian about the integration directions of Armenia. A.A. Tavadyan presented the results of the work at the meeting of the Interparliamentary Commission for Cooperation between the National Assembly of the Republic of Armenia and the Federal Assembly of the Russian Federation, the EABR International Conference "Deepening and Expanding Eurasian Integration," the Eurasian Economic League portal and other portals.
