Micro Flashcards
PED>1?
Price elastic
PED=1
Unitary elasticity (proportional change)
Factors of PED?
Available substitutes
Proportion of income (more spent = more elas)
Time ( if bought every 2 years then more inelas)
YED?
%^Y
YED sign matters
-ve = inferior goods \+ve= normal goods
YED>1
Income elastic
YED luxuries?
Relatively large YED (always positive)
XED?
%change P good b
XED sign matters
\+ve = substitutes -ve = complements
Larger value = closer compliment / substitute
PES?
%^ P
PES>1
Elastic
Able to respond with change in supply if price changes
PES =1
Change in price = change in demand (proportional)
Determinants of PES?
-Availability of stocks (Price^ then stocks sold at high price) (Price fall the stored and sold when P^) -Availability of fops (Spare capacity etc)
Business significance of PED?
- pricing products
- maximise revenue ( if Inelastic then ^ supply)
Business significance of YED
Forecasting future demand
Business prospects
Predict effect of recession or growth on demand for their product
