Although consumers take the use of foods into account when they make purchase decisions, most studies on food consumption have analyzed food demand only by food items without considering it. For accurate analysis on food purchase behavior, it is necessary to classify and analyze foods according to their uses. This study estimated processed food demand in Korea by using the UDAIDS (Usage Differentiated AIDS) model and the data of household account books. Also, it conducted a comparative analysis on the estimation results from the AIDS model and the UDAIDS model. Through the analysis, it found that a food demand analysis using the latter produces more accurate results. |
