The interest in collective action (cooperation) and cooperative work arose during her studies for the Master of International Business at the NBU, where she studied General Agricultural Policy with Prof. Dr. Ivan Boevski as a tutor.
After the defense of her PhD dissertation, this interest grew into the participation of Dr. Tsvetanova in several projects, together with Prof. Dr. Dimitar Nikolov, Prof. Dr. Ivan Boevski and Ch. assistant professor Dr. Krasimir Kostenarov, where agrarian cooperatives are also partially investigated. These participations complement her experience and scientific interests, which are focused on the modeling of economic processes, risk management, credit risk assessment, etc.
