도시가구의 식품비 지출에 대한 연령-세대-연도 효과분석

Abstract

This paper separated generational or cohort effects from aging effects by analyzing the food expenditure patterns of nine cohort groups from 1995 to 2006. For this study, we used data from the Household Income and Expenditure Survey to construct the cohort data set over a 12-year period and to decompose food expenditures into age, time and cohort effects. This study found that all food categories have statistically significant generational effects; younger cohorts spent less than older cohorts on cereals, meats, fruits and vegetables, but more on processed cereal products, dairy products, teas and beverage as well as food away from home.
