Based on this information, what is the Herfindahl Hirschmann Index (HHI) for the Widget Industry ?

Answer 1

Answer: 1,448

Step-by-step explanation:

The Herfindahl Hirschman Index (HHI) is used to show how concentrated an industry is. A lower score indicates that the industry is not very concentrated because there are multiple firms involved.

A higher score shows that the industry is concentrated and controlled by a few firms.

HHI = ∑ square of every firm market share

= 12² + 13² + 14² + 15² + 16² + 17² + 13²

= 1,448

This industry is relatively competitive.
