In recent years Venezuela and Ukraine have had much higher nominal interest rates than the United States while Japan has had lower nominal interest rates. What would you predict is true about money growth in these other countries? Why?

The Fisher effect says that increases in the inflation rate lead to one-to-one increases in nominal interest rates. The quantity theory says that in the long run, inflation increases one-to-one with money supply growth. It follows that differences in nominal interest rates may be due to differences in money supply growth rates. It is reasonable to guess that much higher nominal interest rates in Venezuela and Russia indicate higher money supply growth while lower interest rates in Japan indicate lower money supply growth.
