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.

BALANCE ON SERVICES

A subset of the balance of payments current account that records the difference between the payments received for exports of services to other nations and the payments made for the imports of services from other nations. The flow of payments is for intangible services, not for physical or tangible goods. The balance on services is thus appropriately divided into services exported and services imported. Two other subsets of the current account include the balance on merchandise trade and unilateral transfers. The commonly termed balance of trade is the sum of the balance on merchandise trade and the balance on services.
