Document Summary

Buyers are willing to buy an indefinite amount at the same price ed: percentage change in quantity demanded. Examples: = 10% = - 2 (elastic demand) How price elasticity of demand is calculated ed= % change in quantity. Elasticity at point a (if p ) that- if the price were to fall by 1% then demand would rise by 3% Negative sign indicates that p & q will move in opposite directions. Determinants of price elasticity: number of substitutes. The larger the amount of substitutes- the higher the elasticity of demand. The lower the amount of substitutes- the lower the elasticity of demand: closeness of the substitutes. Closer the substitutes-the higher the elasticity of demand. The more distance the substitutes- the lower the elasticity of demand: i(cid:373)porta(cid:374)(cid:272)e of the good i(cid:374) the perso(cid:374)"s (cid:271)udget. Big chunk of your monthly budget- the higher the elasticity of demand.

1. __________________ A measure of consumersâ sensitivity or responsiveness to changes in the price of a good or service.

2. ___________________ When the percentage change in price (in absolute value) is more than the percentage change in quantity demanded (in absolute value).

3. ___________________ When the percentage change in quantity demanded (in absolute value) is more than the percentage change in price (in absolute value).

5. ___________________ Total amount paid to a producer for a good or service P * Q.

6. ___________________ The effect on total revenue of a change in price, holding quantity constant.
