DEFINITION of 'Domestic Corporate Goods Price Index Japan'
A Japanese index that measures the prices of goods created by firms at the producer and wholesaler level in Japan. The Domestic Corporate Goods Price Index (CGPI) tracks changes in supply side prices within the Japanese economy. Changes in the CGPI often precede changes in the overall Consumer Price Index, as input values determine the overall retail values of the consumer goods. Thus, a large increase in the domestic CGPI will lead to a large increase in the overall CPI.
BREAKING DOWN 'Domestic Corporate Goods Price Index Japan'
