Türkiye’de Ev Dışı Gıda Harcamalarının Kohort Analizi

Öz

Bu çalışmada Türkiye İstatistik Kurumu tarafından derlenen 2002-2018 yılı Hanehalkı Bütçe Araştırmaları Anketi verileri kullanılarak Türkiye'de hanelerin ev dışı gıda harcamaları incelenmiştir. Hanelerin ev dışı gıda harcamaları üzerinde hane özelliklerinin ve hanedeki bireylerin sosyo-demografik özelliklerinin yanında yaş, zaman ve kohort etkisi Çift Eşik modeli ile incelenmiştir. Elde edilen bulgular incelendiğinde bireylerin ev dışı gıda harcamalarının hem katılım hem de tüketim kararında kohort ve yaş etkisi önemli bulunmuştur. Bulgular, daha genç kohortlar için ev dışı gıda harcamasının daha yaşlı kohortlara göre daha hızlı arttığını göstermektedir. Kohortlar ve yaş grupları için gıda esneklikleri ise en genç kohortlardan ve en genç yaş gruplarından, en yaşlı kohortlara ve en büyük yaş gruplarına doğru artmaktadır. Sonuç olarak Türkiye'de gelir ve demografik değişkenler ev dışı gıda tüketiminde, katılım ve tüketim kararlarını etkilemektedir.

A Cohort Analysis of Food Expenditure Away From Home in Turkey

Öz

In this study, the expenditures of food away from home of households are examined using the Household Consumption Expenditure Survey, which was conducted by the Turkish Institute of Statistics from 2002 to 2018. We adopt the Dependent Double Hurdle model with the incorporation of age, period, and cohort effects and the impact of socio-demographic variables. Analysis results reveal that the cohort and age effects are significant in both participation and consumption on food expenditure away from home of household. The findings suggest that the expenditure of food away from home for younger cohorts rises faster for older cohorts. The elasticity of food expenditures for cohorts and age groups is increasing from the youngest cohort and from the youngest age group to the oldest cohort which is the largest age group. The results show that participation and consumption decisions are significantly affected by income and demographic characteristics in Turkey.
