Policy evaluation of Public Financial Institutions from the view points of flow of funds

The purpose of this paper is to develop an experimental model which links inter-institutional flow of funds to real macroeconomy and then to estimate quantitatively the effects of changing scale of postal savings or government financial institutions on GDP. The empirical analysis indicates that at least after 1980 expanding size of postal saving and government financial institutions had negative effects on GDP. It implies that reducing scale of public financial institutions could improve the performance of real macroeconomy.
