The Competition Board has opened an investigation with
the decision of 27.04.2017 on the seven guardrail producers and their
association (TOD). The Board has alleged that these producers restricted the competition in
the guardrail tenders by determining jointly their bids (price quotations) in
these tenders under TOD. In this article, it was analyzed whether a competition
infringement occurred or not by using a wide range of data on guardrail
tenders. The results showed that the ratios between price quotations of
producers and the approximate costs announced by the Administration (bid /
approximate cost) have increased in 2016 as claimed by the Board. However, this
increase did not arise from the fact that TOD members who are parties to the
investigation are in a cooperation restricting the competition. Instead, the
reason for this increase is that the actual costs incurred by the producers
increased while the approximate costs announced by the Administration in 2016
fell.

Rekabet Kurulu 27.04.2017 tarihli
kararında yedi otokorkuluk üreticisine ve bu üreticilerin kurmuş olduğu sektör
derneğine (TOD) soruşturma başlatmıştır. Kurul, bu üreticilerin otokorkuluk
ihalelerinde verdikleri fiyatları TOD çatısı altında birlikte belirlemek
suretiyle aralarındaki rekabeti kısıtladıklarını iddia etmiştir. Bu makalede,
otokorkuluk ihalelerine ilişkin geniş bir veriseti kullanılarak rekabet
ihlalinin oluşup oluşmadığı analiz edilecektir. Sonuçlar, Kurul tarafından
iddia edildiği gibi fiyat teklifleri ile İdare tarafından açıklanan yaklaşık
maliyetlerin oranlanmasından oluşan teklif oranlarının (teklif/yaklaşık
maliyet) 2016 yılında arttığını göstermektedir. Ancak, bu artış soruşturmaya
taraf olan teşebbüslerin rekabeti kısıtlamalarından kaynaklanmamaktadır.
Artışın nedeni, 2016 yılında bir yandan üreticilerin katlandıkları maliyetler
artarken diğer yandan İdare’nin yaklaşık maliyeti düşürmesidir.
