Elementary Theory Of Demand

3 entries

Q_x = f(P_x)
Law of demand states the inverse relationship between price and quantity demanded, keeping other factors constant (ceteris paribus).

Elasticity of Demand

5 entries
E_{d}=\frac{\text { Percentage change in quantity demanded }}{\text { Percentage change in price }}
E_{d}=\frac{\frac{\Delta Q}{Q}}{\frac{\Delta P}{P}}=\frac{\Delta Q}{Q} \times \frac{P}{\Delta P}
\mathrm{TE}=\mathrm{P} \times \mathrm{Q}
When quantity demanded does not change at all with a change in price, demand is perfectly inelastic and Ed = 0.
When percentage change in demand is equal to percentage change in price, Ed = 1.

Consumer Behaviour Cardinal And Ordinal Utility Analysis

6 entries
TU_x = MU_1 + MU_2 + ... MU_(n-1), MU_n
MU = ΔTU/ΔQ
MU = TU2 - TU1
MU_X/P_X = MU_Y/P_Y = ... = MU_n/P_n
MU of the commodity / MU of money = Price of the commodity
