Telekomunikasyon sektöründe doğal tekel sorunsalı ve Türk telekomünikasyon sektöründe rekabet: Sabit hat hizmet piyasası

In a natural monopoly market, it is not possible to create a liberal and competitive market only with economic regulations. In such kind of markets, there is a need for sectoral and legal regulations which determine the rights and obligations of the suppliers and the relationship between the incumbent provider which has the national infrastructure and network and alternative service providers. However, the regulations may not be sufficient to create a competitive market in case of lack of implementation. In this respect, the monitoring unit in the sectoral regulation system has a key role to prevent anti competitive practices such as predatory pricing, cross-subsidization or any other kinds of entry or exit restrictions which arises from the incumbent?s behaviors in the market.Telecommunication sector is one of the markets which has the characteristics of natural monopoly. In this thesis, the liberalization and deregulation process in the Turkish telecommunication fixed-line services will be analysed through regulations and it aims to give an answer whether the fixed line market is competitive and if not, why competition could not be created in Turkish Fixed Line Telecommunications Market and what kinds of policies could be adapted in order to create competition in Turkish Fixed Line Telecommunication Market.
