The history of natural gas in Turkey started in 1970s by the usage of domestic gas in cement factories. However, natural gas began penetrating the energy market in 1980s with the usage of natural gas in Ankara. In the following years, the number of cities using natural gas reached six. Then, a new era started with the enactment of Natural Gas Market Law in 2001 and 53 distribution tenders have been realized by Energy Market Regulatory Authority until 2009. This thesis analyzes the performance of 38 Turkish natural gas distribution companies by using a non-parametric method, Data Envelopment Analysis. The results are used to determine the most proper model specification, to detect the important criteria affecting the efficiency levels and to find the common characteristics of the most inefficient firms. The results show that public firms compared to private firms, non-tender firms compared to tender firms, large firms compared to small firms and firms operating in more developed areas compared to firms operating in underdeveloped areas utilize resources and manage costs more efficiently. However, we can not get a certain conclusion about the comparison of old firms and new firms. Lastly, we try to detect the common characteristics of the most inefficient firms and find that the major problem is low delivery amount.

Estimates of demand relationships for figs and figs products in Turkey
Eriten, Alper; Öcal, Nadir; Department of Economics (2005)
This dissertation measures the extent of relationship between production, processing and marketing channels of fig products in Turkey for the period 1971-2003. We first provide a detailed analysis of world and Turkish fig products market. We then estimate the own price and cross price elasticities of fig products in Turkey by using simultaneous systems. The results imply that the demand facing Turkish dried fig processors is inelastic. Moreover also the producer-level dried fig price elasticity has inelasti...

Bahce, Serdal; Taymaz, Erol (Elsevier BV, 2008-07-01)

The liberalization of the electr...
