The Marginal Private Benefit and Cost of Education in China

This document discusses the marginal private benefit and cost of education in China. It calculates the market equilibrium quantity and price of education and analyzes the marginal private benefit and cost diagram. It also suggests government policies to improve the market outcome.

Question 3: Consider the apples in a small country. Domestic demand and supply is given by ....5
When government allows for international trade then equilibrium state changes from 6 units to 5
units. Therefore, equilibrium price decreases with increases in quantity. Under this condition,
winners are international companies who purchase apples on low price and sell it on high price.
While looser will be domestic country and buyers. .......................................................................6

Question 1: The marginal private benefit and (demand) and marginal private
cost (supply) of education in China are described by
P = 100 – 0.1 QD
P = 10 + 0.1 QS
a) Calculate the market equilibrium quantity and price of education
Solution: At equilibrium condition, Quantity of demand = Quantity of supply
QD = QS
(100 – P) * 10 = (P – 10) * 10
2P = 110
P = 55
Therefore, price of education is $55.
Market equilibrium quantity, (100 – P) * 10 = (100 – 55) * 10 = $450
Henceforth, Equilibrium Price = $55
Equilibrium Quantity = $450

c) An economist has estimated that consumption of education generates a positive externality of
$10 a unit. Calculate the social optimum and deadweight loss.
Solution: Socially optimal output is achieved when output is occurred by the intersection of
marginal social cost (MSC) and marginal social benefit (MSB) therefore, also known as
allocatively efficient level of output.
Marginal social cost = Marginal Profit Cost + Externality
= (100 – 0.1 QD) + 10
= 110 – 0.1 QD
Marginal social benefit = Marginal Profit Cost + Externality
= (10 + 0.1 QS) + 10
= 20 + 0.1 QS
Therefore, Marginal optimum = $65

d) What policy could the government implement to improve the market outcome?
Government play an important role in improving the market outcome by implementing
various policies. For improving educational system and promote education, cash transfer policy
helps in increasing enrolment and attendance. Through Conditional cash transfer, regular

payment can be provided to poor household for meeting their certain conditions and engaging
children of them in education.
