Price Determination in Competitive markets Flashcards
What are the factors affecting demand
PIRATES
- Population
- Income
- Related goods
- Advertising
- Expectation
- Seasons
What is Diminishing Marginal Utility
Foe every extra unit of goods that are consumed the marginal utility (benefit derived) from that good decreases
What is the price elasticity of demand equation
%∆Q/%∆p - responsive ness of a change in demand to a change in price
PED value for elastic good
> 1
PED value for inelastic good
<1
what is the value of PED for
- unitary elastic
- perfectly inelastic
- perfectly elastic
1
0
infinity
factors affecting Price elasticity
Never Say A Parrot Doesn’t Perform
- Necessity
- Substitutes
- Addictiveness
- Proportion of income spent
what is the equation for income elasticity of demand
%∆Q/%∆y
what is an:
- Inferior
- Normal
- Luxury good
and there YED values
- inferior - demand falls as incomes rise
YED<0 - Normal food - Demand increases as incomes rise
YED>0 - Luxury good - Demand increase is bigger than the initial increase in income
YED>1
what is the equation for cross elasticity of demand
XED = %∆Q of X/%∆P of Y
what is a complement good and what is its XED value
Compliment good - if the price of one falls the quantity demanded of both increases
XED<0
what is a substitute good
- what is its XED value
- What is special about the demand curve
- Substitute goods can replace other goods
- XED>0
- this means the demand curve is upward sloping due to the positive gradient
What is XED value for unrelated goods
0
why are firms interested in XED
it allows them to see the extent of there competition
What are the factors affecting Supply
PINT b
- Productivity
- Indirect tax
- Number of firmsg
- Technology
- barriers
what are three factors affecting PES
- Unused/mobility/availability of FOP
- total stock
- Time scale
what is:
- Derived demand
- Composite Demand
- Joint Demand
- Joint supply
- Derived demand - when demand for a good or service is derived from the demand for another good or service
- Composite demand - When the good demanded has more than one use
- Joint Demand - when goods are bought together
- Joint supply - Increase of supply of 1 good will cause an increase in supply of another good
