Economic agents (including policy makers) make their decisions by focusing on economic performance of their economies in their currencies rather than a foreign currency. This shows that we must build a local currency-based model in order to analyze economic issues. However, international input-output tables are denominated in a specific currency. In this paper, we create international input-output tables in constant prices and local currencies by using the tables in the usual formats. Furthermore, we illustrate the theoretical structure of a local currency-based international input-output model which is built on the resultant international input-output tables. Since the model is local currency-based and can account for international economic interdependence, it enables us to analyze domestic economic policies as well as global economic issues by one unified system. The model has a great potential to become a new benchmark framework for multi-country multi-sectoral modeling.
