Comparable studies form the basis for: development of newer foreign trade theories; inclusion of the new teoretical developments into the general equilibrium models and their use for the assessment of the effects of multilateral liberalisation of world trade, regional economic integrations and the effects of current economic policy measures; development and use of the theory of monetary integration and optimal currency area for the study of the importance of asymetric schocks in the process of monetary integration; development of the theory of internationalisation ond globalisation of world economy and the sudy of the effects on developed and undeveloped countries, as well as for the development of the theories of regional development. Research work done within the research programme group adds to scientific methods and findings through the use of the theory and developed methods within the context of the small, open economy in the processes of transition and inclusion into the EU and global trade and financial flows. Collaboration of the research group within several international projects in the same time represents inclusion of the research results into the broader, international contents and therefore an important value added for development of methodological tools (for instance the inclusion of the Slovenian module into the EU general equilibrium model GEM-E3). At the same time this close international cooperation only once again confirm the right direction of research activities and the quality of the research group, which is capable to provide the proposals and also research outputs, which fulfill the raising demands for better application of results and their implementation into development and economic policy.
