HHI measures market concentration and is a metric used by government oversight bodies in the U.S. to determine if a merger should be allowed or blocked. 6 Apr 2018 According to our calculation, the net interest margin has been volatile over the years (see Figure 1), which means the traditional operating Abstract—An interval estimate is provided for the. Herfindahl-Hirschman Index ( HHI) when the knowledge about the market is incomplete, and we know just the We compare the application of two different normalization procedures for the Herfindahl-Hirschman Index. We show that structural differences exist between the Thus, the HHI calculation was the sum of hospitals' squared CBSA-level shares plus the squared non-CBSA hospital share. The HMI competition measures are Inspired by the Herfindahl-Hirschman Index, the Capital Concentration Index™ ( CCI) measures the degree to which venture capital dollars are consolidated
