“…Indeed, the aggregated models can be divided into two since some models estimate import demand as a function of aggregate income-expenditure (Kotan and Saygılı (1999), Masih and Masih (2000), Hooper et al (2000), Aydın et al (2004), Camarero and Tamarit (2004), Islam and Hassan (2004), Razafimahefa and Hamori (2005), Bahmani-Oskooee and Kara (2005), Yavuz and Güriş (2006), Aker (2008), Tang (2008), Chen (2008), Adnan (2008), Ziramba (2008), Petreski (2009), Bayraktutan and Bıdırdı (2010), Narayan and Narayan (2010), Omotor (2010), Alam and Ahmad (2011)) while some others take aggregate import as a function of disaggregated income expenditure namely, consumption, investment and exports components (Tang (2005), Zhou and Dube (2011), Chani and Chaudhary (2012), Modeste (2011)). In these studies the rational of disaggregating income-expenditure is explained as avoiding aggregation bias resulting from use of a single aggregate expenditure variable in the import function when different macro components of final expenditure produce different impacts on imports.…”
