Question:
Consider a general demand function for a good, X, that has been estimated as:
{eq}Q(d) = 200 - 8*Px + 2*Py + 0.4*M {/eq},
where Px is the price of the good being studied
Py is the price of a related good, Y and
M is per capita income.
a) Are X and Y complement, substitutes, or neither? How do you know?
b) Is X a normal good or an inferior good? How do you know?
c) Calculate the direct demand function, assuming that the price of Y is $6 and that per capita income is $38,000.
d) Calculate the inverse demand function, using your answer to c).
Law of demand
Law of demand states that if a consumer's demand for a good move in the same direction as the consumer's income, the consumer's demand for that good must be inversely related to the price of that good. Thus, the demand curve is linear and negatively sloped.
