MOBİL İLETİŞİM TALEBİNİN ÖZELLİKLERİ: TÜRKİYE ÖRNEĞİ

Bu çalışmada mobil iletişim için tanımlanan farklı talep tipleri tartışılarak talebin fiyat esnekliği, gelir esnekliği ve çapraz fiyat esnekliği Türkiye örneği için analiz edilmiştir. Çoklu doğrusal regresyon yaklaşımının tercih edildiği analizde 2001-2017 yılları arasındaki 68 çeyrek dönemlik zaman serileri kullanılmıştır. Bu çalışma, Türkiye Mobil Telekomünikasyon Piyasasının en kapsamlı ve güncel analizdir ve ampirik piyasa analizi literatürüne de katkı sağlamaktadır. Elde edilen sonuçlara göre talep esneklikleri talep türlerine göre şöyledir: Ağa katılma talebinin fiyat esnekliği (-1.4), gelir esnekliği (0.7) ve çapraz esneklik (-0.2)’dir. Ağı kullanma talebinin fiyat esnekliği (-0.2), gelir esnekliği (0.4) ve çapraz esneklik (0.4)’dür. Yayılma talebinin fiyat esnekliği (-1.3), gelir esnekliği (0.6) ve çapraz esneklik (-0.2)’dir.

CHARACTERISTICS OF MOBILE COMMUNICATION DEMAND: THE CASE OF TURKEY

In this study, different types of demand for mobile communications are discussed and price elasticity, income elasticity and cross-price elasticity of demand are analyzed for the case of Turkey. In the analysis, multiple linear regression approach is preferred and 68 quarterly time series between 2001 and 2017 are used. This study is the most comprehensive and up-to-date analysis of the Turkey Mobile Telecommunications Market and contributes to the empirical market analysis literature. The results obtained are as follows: The demand for access to network has (-1.4) price elasticity, (0.7) income elasticity and (-0.2) cross elasticity. The demand for network usage has (-0.2) price elasticity, (0.4) income elasticity and (0.4) cross elasticity. The demand for mobile diffusion has (-1.3) price elasticity, (0.6) income elasticity and (-0.2) cross elasticity.
