Summary

SRI-Hitotsubashi consumer purchase indices, are calculated based on the POS data of 4000 stores, such as supermarkets, convenience stores, drug stores, and large retail stores. In SRI-Hitotsubashi consumer purchase indices, we break down changes in consumer expenditures into price, quantity, and the effect of product turnover, which are shown in "Consumer-purchase Expenditure Index", to see the change in the price of consumer purchases, which are shown in "Consumer-purchase Price Index ", to see the change in the quantity of consumer purchases "Consumer-purchase Quantity Index ", to see the effect of products turnover in consumer purchases, which are shown in " Consumer-purchase Turnover-effect Index ".
