another good. A cross elasticity of demand that is not equal to zero will indicate that the goods are related. A positive elasticity
indicates substitutes. A negative elasticity indicates complements. Same as cross-price elasticity of demand.

DEMAND FOR MONEY: The quantity of money that people want to hold at each potential interest rate. An inverse relationship exists
between the interest rate and the quantity of money demanded.

the banking system. It is the reciprocal of the reserve requirement. Also called the money multiplier.
DEPRECIATION: The replacement cost of worn-out machinery and equipment.

consumer income, consumer tastes, the prices of complements, the prices of substitutes, consumer expectations, and the
number of potential buyers.
