Abstract

A Herfindahl index of constructed from shares based on count data where the number of counts is small will generally be biased downward because of the statistical properties of count data and Jensen’s inequality. This note suggests a simple correction for the bias and illustrates its applicability when using measures based on patent data and patent citation data.
