Economic Transformation to a Market Economy

The complex transformations taking place in  the post-communist countries are hard to scrutinize and appraise theoretically. One of the ways to summarize the changes is the input output analysis of intersectoral flows of a national economy.  The images below present our solution  to inspect these transformations visually. Treating input-output data as a weighted graph, we use graph drawing procedures to inform us about the overall structure of the economy and the importance of different sectors.
