LERNER INDEX: The difference between price (p) and marginal cost (mc) as a fraction of price, that is [p-mc]/p. The Lerner index is usually taken as an indicator of market power because the larger the index, the larger the difference between price and marginal cost, that is, the larger the distance between the price and the competitive price. The Lerner index depends on the elasticity of demand. The Lerner index is also called the price-cost margin.

AMERICAN ECONOMIC ASSOCIATION A formal organization of professional economists that promotes economic research, organizes annual meetings and conferences, and maintains a list of publications in several economics subjects. The American Economic Association (AEA) was originally organized by a small group interested in economics at a meeting in 1888 in Saratoga, New York. However, as interest in the subject grew, it officially incorporated in 1923. Although the AEA contained only a small number of members in the beginning, today the membership is approximately 18,000. In addition, about 4,600 libraries, institutions, and firms subscribe to the quarterly publications of the AEA.
