TANGENCY: A geometric condition that occurs when two curves touch at a single point with identical slopes at that point. This condition of tangency surfaces in several different areas of economic analysis, including indifference curve analysis (tangency between an indifference curve and budget line) and monopolistic competition (tangency between demand curve and long-run average cost curve). The tangency between two curves should be contrasted with the condition of intersection, in which two cross at a single point but do not have identical slopes.

LEGAL RESERVES

The combination of vault cash and Federal Reserve deposits that banks can legally use to satisfy government reserve requirements. Legal reserves, which can also be considered total reserves, are divided between require reserves and excess reserves. Required reserves are used to back up deposits and process daily transactions, while excess reserves are then available for interest-paying loans.
