Markets are efficient Adam Smith, 1776 – the “invisible hand of
the market” Markets allocate resources using the price
mechanism (shortage, surplus, equilibrium) Allocation is automatic due to the signal and
incentive role of price Related markets are concatenated (linked)
through demand and supply, and the price mechanism
Result is social optimum (community surplus maximized) at equilibrium price

Markets are efficient BUT… Adam Smith, 1776 – the “invisible hand of the market”
Markets allocate resources using the price mechanism (shortage, surplus, equilibrium) Allocation is automatic due to the signal and incentive role of price Related markets are concatenated (joined) through demand and supply, and the price
mechanism Result is social optimum (community surplus maximized) at equilibrium price
Governments intervene in markets using their legal authority to…▪ Raise funds through taxation▪ Regulate activity (enforce laws)▪ Support industries through subsidies▪ Provide public goods, and merit goods ▪ Deal with “externalities”, e.g. pollution

I would like you to…
Consider government intervention in markets as a question! Should government intervene?▪ Maybe yes, maybe no… it all depends
Sometimes government action helps resource allocation, and sometimes it doesn’t! You have to weigh the plusses and
minuses of the results of government action

Forms of Intervention
Taxes – indirect and direct taxes Government takes funds $$$
Subsidies – industry support Government gives funds $$$
Price Controls – government sets prices Ceilings Floors Minimum Wages
![Page 6: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/6.jpg)
Governments need money For 99% of the world, governments
get the money they need in the form of taxes
Goods and Services are taxed (indirect tax)
Income is taxed (direct tax)
This revenue allows government to provide services
(Governments also borrow money)

Types of Taxes
Specific tax, per unit (domestic) Excise tax, per unit (domestic)
Value-added Tax, percentage (domestic)
GST, percentage (domestic)
Customs Duty, percentage (international)
![Page 8: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/8.jpg)
Per Unit Taxes Look Like…
Supply curves are parallel because the same amount of tax applied for each unit of output
Excise tax, specific tax look like this
![Page 9: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/9.jpg)
Percentage Taxes Look Like…
Supply curves diverge from the origin because the amount of tax rises as output increases, e.g. 10% of price10% of $100 = $10 while 10% of $300 = $30
Sales Taxes, VAT, GST and Customs Duties look like this
![Page 10: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/10.jpg)
INDIRECT TAXES – The Theory
Indirect taxes are imposed on goods and services by the government.
The burden is shared between consumers and producers.
Taxes are remitted by producers to the government.
Direct taxes are on the income of the citizen directly, e.g. income tax (more later)
![Page 11: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/11.jpg)
Types of Indirect Taxes Excise Tax: Taxes imposed on particular
G+S– usually goods with inelastic demand eg: petrol, cigarettes and alcohol
Thinking Point: Can you think of an economic reasons why governments target these types of goods??
General Sales Tax (GST) or Value Added Tax (VAT): Taxes imposed on all or (most) G+S
![Page 12: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/12.jpg)
Indirect Excise taxes can be either: Specific Tax: A tax of a specific amount to
be paid on every unit of a product sold. Eg: $2 per pack tax on cigarettes.
Ad Valorem Tax: A tax based on a particular percentage of the sales price of a product. In this case the tax increases as the price of G+S increases.
Eg: 50% tax on sales of cigarettes ($PxQ)

Specific Tax Diagram
S2 curve is parallel to S1.Amount of tax is fixed for each unit of output
![Page 14: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/14.jpg)
Ad Valorem Tax DiagramS2 curve is steeper than S1 because tax increases as price increases
If tax = 10% and P = $ 20 Tax per unit sold = $2 (0.1x 20)
If Tax = 10% and P = $ 30 Tax per unit sold = $ 3 (0.1x 30)

WHY DO GOVERNMENTS IMPOSE INDIRECT TAXES (EXCISE TAX)?
Source of Government Revenue Method to discourage consumption of
goods that are harmful to individuals/ society
Tax revenues used to redistribute income from rich to poor
Method to improve allocation of resources (reduce allocative inefficiency) or to correct negative externalities
![Page 16: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/16.jpg)
IMPACT OF INDIECT (EXCISE TAX) ON THE MARKET
When tax is imposed on G+S it is paid to government by firms.
This leaves fewer resources for production, c.p.
Thus, for every price the firm produces less
The supply curve shifts left Let’s use diagrammatic analysis to find
the extent of the reduction in output, and the incidence of the tax burden
![Page 17: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/17.jpg)
Market Outcomes of Specific Tax
Before Tax: P* = Eqb P Q* = Eqb Q (intersection of S1 & D curves)
After Tax: S curve shift to S2 (S1+Tax) P paid by consumers increase to Pc and Q falls to Qt.Pc= P paid by consumers Amount of tax = Pc – Pp (tax per unit)
![Page 18: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/18.jpg)
The market outcomes due to the Specific tax Equilibrium quantity produced and consumed fall from
Q* to Qt Equilibrium price increases from P* to Pc (P paid by
consumers) Consumer expenditure on the good changes from P*x
Q* to Pc x Qt Price received by firms fall from P* to Pp =( Pc – tax) Firm revenues fall from (P* x Q*) to (Pp x Qt) Government receives tax revenues = (Pc – Pp) x Qt
amount of tax per unit times the number of units sold (shaded area)
There is an under allocation of resources to the production of the good Qt less than free market Q (Q*)

Market Outcomes of Ad Valorem Tax
Before Tax:
After Tax :
Student Task: Use same steps as the previous diagram to determine the market outcomes

The Market outcomes due to an Ad Valorem Tax
Outcomes are exactly the same as the specific tax – just relate back to diagram (b) instead.

CONSEQUENCES OF INDIRECT EXCISE TAXES ON STAKEHOLDERS
Stakeholders affected

Government
Society
![Page 22: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/22.jpg)
Consumers
Consumers (households) are worse off – how?? Pay higher prices Consume less quantities Spending is reduced also on other
goods due to paying more on the taxed good
Increase consumption of substitute good which may be less desirable.
![Page 23: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/23.jpg)
Producers
Producers (firms) are worse off – how?? Receive lower prices than before Sell less quantities – ie leads to lower
revenues and profits Firms produce less output so leads to
supply shortages in the future
![Page 24: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/24.jpg)
Government
Governments are the only winners from taxes Increase revenues – lead to budget
surpluses Decrease spending on public goods
such as health care and environment because people who smoke or use petrol now contribute to the costs
![Page 25: Taxes. Adam Smith, 1776 the invisible hand of the market Markets allocate resources using the price mechanism (shortage, surplus, equilibrium)](https://reader035.vdocuments.us/reader035/viewer/2022062413/5a4d1b717f8b9ab0599b5421/html5/thumbnails/25.jpg)
Society as a whole
Society as whole is worse off due to higher prices of goods and lower quantities consumed and produced.
Allocative inefficiencies – society not producing what is desirable
