Data for 'Monopsony Rent Surcharges for SDG Financing: The Case of Japan'
Description
The shortage of financial resources for achieving the Sustainable Development Goals (SDGs) is a serious issue. This study attempts to estimate the amount of monopsony rent surcharges which would be able to be imposed on large corporations in Japan as a financial resource for achieving SDGs. Using the dynamic pseudo-equilibrium approach and mathematical programming, the results show that the average total amount of monopsony rent of 5581 Japanese companies was 10,098.4 billion yen per year in the 2010s. Additionally, the sum of the corporate income tax rate and monopsony rent rate consistently remained at approximately 50% from 1980 to 2020, while the corporate income tax rate declined from approximately 44.7% to less than 27.9%. These folders contain the data and programs used for the above estimation, and a brief explanation of them is given below.
