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.

RISK PREFERENCES

Three alternative views concerning the choice between a risky outcome and a certain outcome -- risk aversion, risk neutrality, and risk loving. Some people prefer to avoid risk (risk aversion), others enjoy engaging in risk (risk loving), and still others are indifferent (risk neutrality). Most people are risk averse, which underlies the provision of insurance. Others who are risk loving are more inclined to gamble, play the stock market, and be entrepreneurs.
