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.

AUTONOMOUS SAVING

Household saving that does not depend on income or production (especially disposable income, national income, or even gross domestic product). That is, changes in income do not generate changes in saving. Autonomous saving is best thought of as a baseline level of saving (usually negative) that the household sector undertakes in the unlikely event that income falls to zero. It is measured by the intercept term of the saving function or the saving line. The alternative to autonomous saving is induced saving, which does depend on income.
