Economic Systems Research is a double blind peer-reviewed scientific journal dedicated to the furtherance of theoretical and factual knowledge about economic systems, structures and processes, their interaction with the natural environment, and their change through time and space, at the subnational, national and international level. The journal contains sensible, matter-of-fact tools and data for modelling, policy analysis, planning and decision making aimed at solving contemporary economic and environmental questions and problems. Economic Systems Research is non-partisan, factual and problem-oriented. As the official journal of the International Input-Output Association (IIOA), it aims to serve as a vehicle of cross-cultural information and contact. Topics within the purview of the journal include linear and non-linear multisectoral models of structure and structural change and development, ecosystems and the treatment of depletable resources, environmental and strategic questions, life-cycle assessment, databases and databanks, large-scale computational methods and languages. The journal includes reviews of pertinent literature and special issues on new emerging areas of research in its field.
