Answer to Problem 10CACQ

The cost to the government in buying the firm’s unsold units is $480.

Explanation of Solution

Equilibrium price and quantity is calculated at a point where Qxs=Qxd

Substituting the values,

16+Px=922PxPx+2Px=92+163Px=108Px=$36

Equilibrium price of the commodity is $36. At price of $36, equilibrium quantity demanded or supplied is calculated below:

QxS=16+Px=16+36=20

Qxd=922Px=922(36)=9272=20

Therefore, at price $36, the quantity demanded and supplied is 20 units.

When government imposes price floor of $40 then the supplier likes to supply a higher quantity.

Calculate the quantity supplied at price floor $40:

QxS=16+Px=16+40=24

Calculate the quantity demanded at price floor $40:

Qxd=922Px=922(40)=9280=12

It can be observed that the quantity supplied is greater than the quantity demanded.

Quantity demanded of the commodity decreases while quantity supplied by producers increases when government levied price floor. When government imposes price floor then producers want to produce more commodities while consumers demand less commodity as price of commodity is high.

The excess units supplied is 12 (2412)

Calculate the cost of government buying firms:

Costofgovernment=Excessunitssupplied×Pricefloor=12×40=$480

The cost to the government of buying firms unsold units is $480.

Economics Concept Introduction

Demand and supply:

Demand is the total quantity of goods that a consumer is ready and able to buy at various prices, keeping other things constant.Supply is the total quantity supplied by a producer at various prices, keeping other things constant.

Price floor:

Price floor is the maximum price set by the government below which goods are sold in an economy.When government imposes a price floor and agrees to purchase all units that consumer do not buy, it results in the cost to the government as government must purchase remaining unsold goods.

Answer to Problem 10CACQ

The loss social welfare that stems from the $40 price floor is $456.

Explanation of Solution

The government is ready to purchase the difference between the quantity supplied and the quantity demanded in the market that is the surplus quantity in figure 1.

Managerial Economics & Business Strategy (Mcgraw-hill Series Economics), Chapter 2, Problem 10CACQ

Due to price floor and government purchase, there are two types of dead weight loss. First due to higher price some consumer deterred which resulted into usual deadweight loss shown by area A.

Second, the excess produced goods are either destroyed or put in a warehouse and not consumed.

This deadweight loss is the loss of cost of production. The area given by the supply curve and this is the area under the supply curve and government purchases that is area B and C.

Thus, the summation of area A, B and C is the total dead weight loss.

DWL=AreaofA+AreaofB+AreaofC

DWL=CosttothegovernmentAreaofD=$480(12×(2412)×(4036))=$480(12×12×4)=$480$24=$456

Therefore, the loss social welfare that stems from the $40 price floor is $456.

Economics Concept Introduction

Social welfare loss:

Social welfare loss refers to that amount which is usually caused to the whole society by imposition of tax by the government.

    Price Ceiling of Low-Cost Homes   The Malaysian government has implemented a price ceiling on low-cost homes starting from the year 2010. The implementation of this price ceiling is aimed to ensure that people from the lower income group have one of the necessities, which is shelter. The government has set the price ceiling of low-income houses at RM42,000 in Peninsular Malaysia and RM50,400 in Sabah and Sarawak. Furthermore, in conjunction with the 10th Malaysia plan, the government has planned to develop more houses at an affordable price, involving private developers. The target is to have 161,000 affordable homes, of which private developers would build 83,000 units while the rest would be built by the government.Due to the implementation of this price ceiling, the legal maximum price of low-income houses set by the government is lower than the market equilibrium price. This is done in order to protect the interest of consumers by preventing the producers from charging prices that…

    Some have argued that higher cigarette prices do not deter smoking. While there are many arguments both for and against this view, some find the following argument to be the most persuasive of all: “The laws of supply and demand indicate that higher prices are ineffective in reducing smoking. In particular, higher cigarette prices will reduce the demand for cigarettes. This reduction in demand will push the equilibrium price back down to its original level. Since the equilibrium price will remain unchanged, smokers will consume the same number of cigarettes.”Do you agree or disagree with this view? Disagree - the reduction in demand will push the equilibrium price below its original level. Disagree - this confuses a change in demand with a change in quantity demanded. Agree - the price increase will ultimately leave cigarette consumption unchanged. Disagree - higher cigarette prices will actually increase the demand for cigarettes.
