Understanding diversity in food consumption is important both from an economic perspective and from a nutritional consideration. The analysis of food diversity is especially valuable if food diversity can be observed over the life cycle, because consumption levels differ amongst successive birth cohort observed at the same age. This paper describes the dynamics of consumers' demand for food diversity in Korea present in the series of repeated cross-section of the Korean National Statistical Office household expenditure survey for the period 1995-2007. Differently from other studies, I use household data rather than cohort means to carry out a cohort-age-time decomposition of demand for food diversity in a life cycle model. An entropy index was used to evaluate food diversity of sample households. Empirical results show that (i) the diversity in food expenditure has been decreased over 1995-2007, (ii) food diversity increases until the ages of 30-34, while it decreases after the ages of 35-39, (iii) younger generations have less demand for food diversity, thus implying that the decrease in food diversity is due to the difference in generations, and iv) the cohort effect was not affected by introducing various demographic variables into the model for food diversity demand.
Abstract
Understanding diversity in food consumption is important both from an economic perspective and from a nutritional consideration. The analysis of food diversity is especially valuable if food diversity can be observed over the life cycle, because consumption levels differ amongst successive birth cohort observed at the same age. This paper describes the dynamics of consumers' demand for food diversity in Korea present in the series of repeated cross-section of the Korean National Statistical Office household expenditure survey for the period 1995-2007. Differently from other studies, I use household data rather than cohort means to carry out a cohort-age-time decomposition of demand for food diversity in a life cycle model. An entropy index was used to evaluate food diversity of sample households. Empirical results show that (i) the diversity in food expenditure has been decreased over 1995-2007, (ii) food diversity increases until the ages of 30-34, while it decreases after the ages of 35-39, (iii) younger generations have less demand for food diversity, thus implying that the decrease in food diversity is due to the difference in generations, and iv) the cohort effect was not affected by introducing various demographic variables into the model for food diversity demand.
