HHI: The common abbreviation for the Herfindahl-Hirshman index (or the Herfindahl index), which is a measure of concentration of the production in an industry that's calculated as the sum of the squares of market shares for each firm. This is an alternative method of summarizing the degree to which an industry is oligopolistic and the relative concentration of market power held by the largest firms in the industry. The Herfindahl index gives a better indication of the relative market control of the largest firms than can be found with the four-firm and eight-firm concentration ratios.

The slope of a line is measured by calculating the change in the value measured on the vertical axis divided by the change in the value measured on the horizontal axis. - Another way of saying this is to take the rise over the run.
| rise | change in shoes | | slope = | ---- = | -------------------------- | | run | change in calibrators |
- Slope between I and J is -70. Rise is a decrease of 70. Run is an increase of 1.
The slope of the production possibilities curve is the opportunity cost of the good measured on the horizontal axis, which in our example is clock calibrators.
