Chapter 4 Midterm Flashcards
Elasticity vs Inelasticity DEFINITIONS
elastic: quantity demanded is quite responsive to changes in price (diet coke, car payments, rent, etc)
inelastic: unresponsive to changes in price (cigarettes, alcohol, etc)
How does elastic/inelastic demand look on a graph
(may be incorrect)
supply curve is independent.
-inelastic demand is more vertically pronated
-elastic demand is horizontally pronated
Rule of equilibrium for elasticity
The more responsive QD is to changes in PRICE, the LESS CHANGE in EQUILIBRIUM PRICE, and the GREATER CHANGE in EQUILIBRIUM QUANTITY; resulting from any kind of shift from the SUPPLY CURVE
What are absolute vs percentage changes?
When do they need to be used?
normally better to know percentage change
True or false: Linear demand curves should be evaluated at different given points to find elasticity as they’re elasticity varies across the line?
true
True or false; the further you move down the demand curve the less the price elasticity is
true
true or false, the longer the time span, the more elastic the price elasticty of demand
true
different between short and long run equilibrium
long run equilibrium has price and quantity above those that prevailed in short run equilibrium
T or F Supply elasticity has the same forumla as demand elasticity
True
supply curves (in respect ot this course) all have _____. An increase in Price causes an ____ in quantity supplied? Price and quantity of supply change in ____ direction
- Positive Slopes
- increase
- the same
What are the dtereminants of supply elasticity?
How do they affect it
- EASE OF SUBSITIUTION
if it is easy for a firm to switch production to a substitute, supply will be more elastic - SHORT AND LONG RUN
elasticity of a good is greater when it is over a longer period of time than a shorter one (with some exemptions of change).
How is quanitity demanded and price affected by short and long term equilibriums
SHORT: inability to change output in short run will result mostly in a change of price
LONG: as firms are increasingly able to produce, the consequences of a demand shift are more on quantity and less on price. MORE ELASTIC
what is tax incidence
the use of elasticity to determine whether consumers or producers bear the burden of taxes
what is excise Taxes
special sales taxes on the fun stuff. Burden is distributed between consumers and producers depending on relative elasticities of supply and demand
in the new equilibrium, the quantity exchanged is ____ than what occurred without the tax
Less than
