Competitive Conditions in the Turkish Non-Life Insurance Industry Adnan Kasman 1 * Evrim Turgutlu2 Abstract: This paper investigates the evolution of market structure in the Turkish insurance industry over the period 1996-2004, using the Panzar and Rosse (1987) methodology. The sample period has been divided into three sub-periods (1996-1998, 1999-2001, and 2002-2004). The results suggest that in the first and second sub-periods, the insurance firms operating in the Turkish insurance industry earned revenues under the monopoly or conjectural variations short-run oligopoly. In the third period, however, the results indicate that insurance market was neither monopolistic nor perfectly competitive. Firm revenues were earned as if operating under monopolistic competition. Overall, the results show that market concentration is not significantly related with competitive conduct.

In particular, policies towards financial liberalization and restructuring with the goal of establishing a competitive environment and enhancing efficiency have been implemented. Deregulation process started predominantly in the banking system. However, transformation phase in the insurance industry followed with 5 to 10 years lag. Until mid-1980s Turkish insurance industry was heavily regulated. New entries were restrained and the prices were set under regulatory conditions. By the end of 1980s the liberalization process started and insurance industry moved gradually from strict regulation towards liberalism. This process has considerable implications for the structure of the industry and conduct of the firms. Hence, Turkish insurance industry offers an attractive field for researchers to examine the evolution of its competitive structure. On the contrary, the literature lacks studies addressing this issue. Merely, a recent study by Celik and Kaplan (2007) focuses on the competitive structure of the Turkish insurance industry over the period 2002-2004. To the authors’ best knowledge there exists no study examining whether or not the market structure of the insurance industry has changed due to the developments in last two decades. In this context, we aim to assess the competitive structure and contestability of the Turkish non-life insurance industry over the period 1996-2004, through three-year sub-periods. We estimate the reduced-form revenue equations for the sample of non-life insurance firms and follow the Panzar and Rosse (1987) approach to test for competition. The accurate measures of the variables (input prices and total revenues) have extreme importance in this methodology. Hence, we aim to contribute the relevant literature by defining an insurance-industry specific revenue function. The rest of the study is organized as follows: Section 2 gives a brief overview on the Turkish insurance industry. Section 3 presents the methodology. Data set, variables and empirical results are reported in Section 4. The last section is devoted to conclusions.
