A New Industry Concentration Index [PDF]

Economic Papers, 2015
We propose and analyse a new concentration index alternative to the Herfindahl‐Hirschman Index (HHI). This new index emphasises the concept of competitive balance. It is designed to preserve the convexity property of the HHI when a merger involves one of the m largest firms, but to decrease and thus to indicate an increase in competition when a merger ...

Refractive index of solutions at high concentrations

Applied Optics, 1988
The refractive index of liquid solutions at the He-Ne laser wavelength, 0.6328 microm, is presented. The measurements were carried out using the conventional minimum deviation method of an equilateral hollow glass prism. The refractive indices of sucrose, sodium chloride, glucose, and caster sugar solutions for a range of density varying from distilled
