Features of the four market structures
Calculation, interpretation/application
PES=(%∆𝑄_s)/(%∆𝑃)
CED (XED)=(%∆𝑄_a)/(%∆𝑃_b)
=0 (or close to 0): no significant relationship >0: substitutes <0: compliments
YED=(%∆𝑄_𝑑)/(%∆Y)
+: normal goods (luxury goods (>1) & necessities (<1)) -: inferior goods
PED=(%∆𝑄_𝑑)/(%∆𝑃)
Elastic product: P rises -> TE falls; P falls -> TE rises Inelastic product: P rises -> TE rises; P falls -> TE falls
PED>1: relatively elastic (flatter demand curve) PED<1: relatively inelastic (steeper demand curve) PED=1: unitary elastic PED=0: perfectly inelastic (vertical demand curve) PED infinity: perfectly elastic (horizontal demand curve)
Price control
Maximum price (price ceiling)
Minimum price (price floor)
Price and output determination (D=S)
Changes of supply/demand
Non-price factors: shift (increase/decrease)
Price factors: move along (expansion/contraction)
