The general demand function for a good, Good A, is:
QD = 800 â?" 5*P + 0.02*M + 6*PR + 3*T + 5*PE + .4*N
Where
QD = quantity demanded of Good A per month
P = the price of Good A
M = average household income
PR = the price of a related good, weâ??ll call it Good B
T = a consumer taste index
PE = the price consumers expect to pay next month for Good A
N = the number of buyers in the market
Explain:
Is Good A a normal good or an inferior good? How do we know exactly?
Are Good A and Good B complements or substitutes? How do we know exactly?
