LONG RUN, MACROECONOMICS: In terms of the macroeconomic analysis of the aggregate market, a period of time in which all prices, especially wages, are flexible, and have achieved their equilibrium levels. This is one of two macroeconomic time designations; the other is the short run. Long-run wage and price flexibility means that ALL markets, including resources markets and most notably labor markets, are in equilibrium, with neither surpluses nor shortages. Wage and price flexibility and the resulting resource market equilibria are the reason for the vertical long-run aggregate supply curve.

Herfindahl Index
|
|
|
- Sometimes economists prefer a more sophisticated measure of concentration. That measure is the Herfindahl index.
- The Herfindahl index is a measure of concentration of production or sales activity in an industry that's calculated as the sum of the squares of market shares for each firm.
- One key difference with concentration ratios is that the Herfindahl index squares market shares before adding them together, whereas concentration ratios add the adjusted market shares.
- Like concentration ratios, the Herfindahl index ranges for a low, indicating perfect competition, to a high indicating monopoly.
- The specific range is 0 (perfect competition) to 10,000 (monopoly).

MONEY MARKET DEPOSITS Interest-paying bank accounts maintained by traditional commercial banks, credit unions, savings and loan associations, and mutual savings banks that pay higher interest rates than standard savings accounts, but with minimum balance requirements and limited check writing capabilities. Money market deposit accounts were developed by banks in response to money market mutual funds offered by mutual fund companies. These deposits are typically considered a type of savings deposits, along with passbook accounts and share accounts. Money market deposits, along with these other savings deposits and assorted near monies, are added to M1 to derive M2.
