Abstract
Bu çalışma,
piyasa gücü ve konsantrasyon oranını ölçmek amacıyla, Herfindahl ve Dominans
Endekslerine benzer fakat hem basit ve ölçeklenebilir hem de böyle bir
endeksten beklenen tüm istenen özellikleri üzerinde taşıyan bir endeks
tanımlamayı amaçlamaktadır. Endeksin, firma sayısı ile negatif, firmaların
piyasa paylarının varyansıyla pozitif orantılı olması gerekmektedir. Amerikan
endüstrisinden alınan örneklere ek olarak, alternatif endeksimizden yola
çıkarak, piyasa paylarının servet üzerindeki etkilerini formülize etmekteyiz.
Diğer yandan, teknolojik gelişmeler ve talep esnekliği, bu çalışmanın
kapsamının dışında kalmaktadır.

Abstract
This study
aims to define an alternative index to measure market power and concentration
ratio, similar to the Herfindahl Index and the Dominance Index in terms of
ease, as a simple and scalable but more consistent scalar number carrying all
the desired properties from such an index, which should be negatively
correlated with the number of firms and positively correlated with the variance
of firm market shares. In addition to examples from the US
industries, based on the alternative index, we also formulate the impact of
market concentration on welfare. The impact of technological progress and
demand elasticity on market power however is not addressed in this study.
