ESTIMATION OF THE DEMAND ELASTICITIES FOR MOBILE TELECOMMUNICATION IN OECD COUNTRIES

Öz

The demand structure in mobile telecommunications markets provides important information about market behavior for policy makers and operators. The main purpose of this study is to examine the demand structure in mobile telecommunication markets with the example of OECD countries and to demonstrate the long-term demand elasticities. In this context, long-term demand elasticities are estimated with the help of the AMG estimator, which allows for heterogeneity, using quarterly panel data for the period of 2005-2015 of 22 OECD countries. According to the results of the estimation in the long-term for the country group, the price elasticity of demand is -0.53 and the income elasticity of the demand is 0.36. Other results show that demand elasticities vary considerably between countries, depending on the countryspecific characteristics

OECD ÜLKELERİNDE MOBİL İLETİŞİMİN TALEP ESNEKLİKLERİNİN TAHMİNİ

Öz

Mobil telekomünikasyon piyasalarında talep yapısı, politika yapıcılar ve operatörler için piyasa davranışları hakkında önemli bilgiler vermektedir. Bu çalışmada temel amaç mobil telekomünikasyon piyasalarındaki talep yapısını OECD ülkeleri örneği ile incelemek ve uzun dönem talep esnekliklerini ortaya koymaktır. Bu bağlamda 22 OECD ülkesinin 2005-2015 dönemine ait çeyrek yıllık panel verileri kullanılarak heterojenliğe izin veren AMG tahmincisi yardımı ile uzun dönem talep esneklikleri tahmin edilmiştir. Tahmin sonuçlarına göre ilgili ülke gurubu için talebin fiyat esnekliği uzun dönemde -0,53 ve gelir esnekliği 0,36’dır. Ortaya çıkan diğer sonuçlar ülkelere özgü niteliklere bağlı olarak talep esnekliklerinin ülkeler arasında ciddi ölçüde farklılaştığını ortaya koymaktadır.
