This paper evaluates the forecasting ability of alternative product growth models for telecommunication services in Turkey. The variable exponential growth model better explains the diffusion process of fixed line services, suggesting that S-shaped models are not able to model the period of the...

The aim of this paper is to analyze the extent of network effects in mobile telecommunications in Turkey, and to identify other determinants of consumer choice based on consumer survey data. This study shows that there are regional disparities in the adoption of network services in Turkey, the...

In this paper we present an economic model contributing to the explanation of religious schism, a topic mostly dealt with in the fields of sociology and psychology so far. The main idea is to see religious groups as networks. These networks may serve as a device for exchanging information about...

This paper estimates demand elasticities for Turkish mobile telecommunications markets. In contrast to most other studies, firm-level data is used to estimate dynamic panel data models including instrumental variable techniques. Both short- and long-run elasticities are calculated, yielding a...

Current economics textbooks and neoclassical economists justify a theory of consumer behaviour based on utility maximisation on a priori grounds. This methodology follows Lionel Robbins' idea that economic theory is based on logical deduction from postulates which are "simple and indisputable...

Enformasyonun üretim sürecinin önemli bir girdisi olduğu günümüz ekonomi- lerinde telekomünikasyon şebekeleri enformasyona dayalı üretimin alt yapısını oluştururken, bu piyasalarda sunulan hizmetlerin ekonomideki yeri de önemli düzeylere ulaşmaktadır. Arz yönünden ölçek...

This paper analyses inflation forecasting power of artificial neural networks with alternative univariate time series models for Turkey. The forecasting accuracy of the models is compared in terms of both static and dynamic forecasts for the period between 1982:1 and 2009:12. We find that at...
