Abstract This paper derives a European Herfindahl–Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, rose due to reallocation of economic activity toward large and concentrated industries.

This paper investigates the pricing of patented traits in the U.S. hybrid corn seed market under imperfect competition. In a multiproduct context, we first examine how substitution/complementarity relationships among products can affect pricing. This is used to motivate multi-product generalizations of the Herfindahl-Hirschman index (GHHI) capturing cross-market effects of imperfect competition...

We study the effect of hospital market concentration on the quality of patient data protection practices. We use approximately 200 reported data breaches in US hospitals over the period 2006 2011 as a measure of the quality of patient data protection practices. We measure market concentration using the Herfindahl-Hirschman Index (HHI) and estimate our models by exploiting cross-sectional HHI va...
