                            <p>Bu çalışmada, hanehalkları arasında mevcut olan sosyal ve ekonomik farklılıklar ile tüketim arasındaki fonksiyonel yapı tespit edilerek, tüketim davranışlarının ampirik olarak incelenmesi amaçlanmıştır. Bu amaçla, Lewbel ve Pendakur  2009  çalışmasında önerilen “Tam Belirlenmiş İlgin Dönüşümlü Stone İndeksi”  EASI  çerçevesinde ampirik model oluşturularak 2003-2011 dönemi için Türkiye İstatistik Kurumu  TÜİK  tarafından hanehalklarına uygulanan Hanehalkı Bütçe Anketi  HBA  üzerinden tahminlerde bulunulmuştur. İteratif Üç Aşamalı En Küçük Kareler  I3AEKK  tahmin yöntemi uygulanarak, 11 temel harcama grubu için referans hanehalkına ait Engel Eğrileri ile gelir ve talep esneklikleri tahmin edilmiştir. Elde edilen ampirik bulgulara göre, Türkiye için yapılan daha önceki çalışmaların aksine, otel harcamaları hariç diğer bütün mal grupları için tahmin edilen Engel eğrilerinin 5. dereceden polinomal bir yapıya sahip olduğu tespit edilmiştir. Ayrıca bu çalışmada, hanehalkları arasındaki gözlemlenebilen ve gözlemlenemeyen heterojenlik ile yıllar arasında ortaya çıkabilecek zevk ve tercihlerdeki değişimin de tüketim harcamaları üzerindeki etkisi ölçülmüştür</p></trans-abstract>

To do so, this paper utilizes the empirical framework of “Exact Affine Stone Index”  EASI , which is offered in Lewbel and Pendakur  2009 , by using the Household Budget Survey data provided by Turkey Statistical Institute, for the 2003-2011 period. The analysis presented here estimates Engel curves, income and demand elasticities for eleven main consumption bundles of the reference household using the Iterative Three Stage Least Squares  I3SLS  method. Differently to previous studies, the empirical results show that the Engel curves have fifth degree polynomial functional form for all consumption groups, except for hotel expenditures for Turkish households. Moreover, this study is capable of measuring the impacts of changes in taste and preferences of Turkish households on their consumption expenditures over the years.</p></abstract>
