Study on Consumption of Clothes by Using the Purchase Price for Each Class of Income

Abstract

The purpose of this paper is to verify the posibility of prediction on the price of each goods by using the relation between the income and the purchase price which were obtained by analysing data of“Family Income and Expenditure Survey”.
The difference of purchase price among each income quintile groups was investigated about thirty-three items including clothes, footwear and bags.
As the result, equations in terms of income and purchase price were obtained for each items of goods. The accuracy of these equations on the prediction was examined and we found that it was possible to predict the purchase price in three years later on twenty-seven out of thirty items of goods.
