The ESRI Short-Run Macroeconometric Model of the Japanese Economy(2015 version): Basic Structure, Multipliers, and Economic Policy Analyses
By Koji HAMADA, Takashi HANAGAKI, Masahiro HORI, Koichiro IWAMOTO,
Taisuke KAMEDA, and Ruriko YOKOYAMA
Abstract
This paper describes the basic structure and multipliers of the 2015 version of The ESRI
Short-Run Macroeconometric Model of the Japanese Economy, which was first released in 1998.
The model is basically a demand-oriented, traditional Keynesian model with IS-LM-BP frame-
work; however, it adopts recent developments in econometrics, such as co-integration and error
correction to ensure long-run properties of the model.
The followings are some of the multipliers of policy simulations. The fiscal multiplier, i.e., the
effect of government investments on GDP, is 1.14 in the first year. The effect of income tax reduc-
tion is slightly smaller (than that of the fiscal expenditures) due to its leak to household savings. 1%
point rise of short-term interest rate reduces real GDP by 0.32% in the first year.
