Studies based on Geographical Simulation Model (IDE-GSM)


The Institute of Developing Economies-Geographical Simulation Model (IDE-GSM) is a simulation model based on spatial economics to estimate economic impacts of various trade and transport facilitation measures by simulating distributional change of population and industries. This project aims to apply IDE-GSM to infrastructure development analyses in Asia and other part of the world, as well as to improve the reliability theoretically and empirically. IDE-GSM has been applied to estimate the economic impacts of various international infrastructure development projects in coordination with ERIA, World Bank, ADB, and ITTLLDC. IDE-GSM is a unique model, especially in Asia, and specialized in ʻagileʼ analysis on large scale infrastructure development projects crossing national borders. We try to accumulate the cases of applied studies in coordination with international organisations, national governments, and academic research institutes, in order to show the importance of policy formulation based on scientific knowledge.
