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.

HORIZONTAL ADDITION: In graphical analysis, the technique of combining two curves by adding the value of the variable on the horizontal or X axis for a given value of the variable on the vertical or Y axis. This is commonly done when deriving a market demand curve from a set of individual demand curves. The quantity demanded by every individual is added at a given price to identify the total market demand at that price.
