Question #106218

the inverse demand functions of two towns for a product are given as ( Q1/2)1/4=P and {2-Q2/10}=P}= P find the market demand of these two towns

b)the supply and demand functions for a product are defined as Q =100 and Qd =50 p -1/2+ 10

i)find the equilibrium price and quantity {Q1/2}1/4

ii)sketch a graph to show the results in i)above

iii)Assume the equilibrium price is 80 pesewas (p=0.80)find the PES and PED associated with a small increase in price from current price of 80 pesewas.

iv)What is the incidence of a tax of Ghs 0.6 imposed on the producr?

b)the supply and demand functions for a product are defined as Q =100 and Qd =50 p -1/2+ 10

i)find the equilibrium price and quantity {Q1/2}1/4

ii)sketch a graph to show the results in i)above

iii)Assume the equilibrium price is 80 pesewas (p=0.80)find the PES and PED associated with a small increase in price from current price of 80 pesewas.

iv)What is the incidence of a tax of Ghs 0.6 imposed on the producr?

Expert's answer

a) (Q1/2)1/4=P and 2 - Q2/10 = P The market demand of these two towns is the sum of individual demands, so:

"2P = Q1\/8 - Q2\/10 + 2,"

"P = Q1\/16 - Q2\/20 + 1."

b) Qs =100 and Qd =50p - 1/2 + 10.

i) the equilibrium price and quantity are:

Qd = Qs,

"50p - 1\/2 + 10 = 100,"

"50p = 90.5,"

p = 1.81,

Q = 100 units.

ii) the equilibrium price and quantity can be shown as intersection point of supply and demand curves.

iii) If the equilibrium price is p=0.80, then PES and PED associated with a small increase in price from current price of 80 pesewas are:

PES = infinity, because the supply is perfectly elastic.

"PED = -50\u00d7(0.8\/100) = -0.4,"

so the demand is inelastic.

iv) If a tax of Ghs 0.6 is imposed on the producer, then the equilibrium price will increase, and the equilibrium quantity will decrease.
