DEFINITION OF SUPPLY
Supply may be defined as the quantity of goods and services which sellers are willing and able to offer for sale at a particular price, and at a particular period of time.
Supply does not mean the entire stock of a commodity in existence or the total quantity of that commodity produced but rather it means only the amount that is put into the market or offered for sale at a given price.
EXPLANATION OF LAW OF SUPPLY WITH GRAPH AND TABLE
1. Law of supply
2. Supply schedule
3. Supply curve
LAW OF SUPPLY
The law of supply states that, all things being equal, the higher the price, the higher the quantity
of a commodity that will be supplied or the lower the price, the lower the quantity of the
commodity that will be supplied.
Supply schedule is the table showing the relationship between the quantity supplied and price of
a commodity. Supply schedule is divided into two:
1. Individual Supply Schedule
2. Market Supply Schedule
The table below shows the supply schedule for bags of wheat.
|Price per bag (N)||Quantity supplied (No. of bag of wheat)|
|An Individual Supply Schedule||Quantity Supplied by||Quantity supplied by||Quantity supplied by||Total Quantity|
|Price per bag N||Mr. Segun||Mrs. Jolaoso||Mr. Ade||Supplied|
MARKET SUPPLY SCHEDULE
Supply curve is a graph showing the relationship between price and quantity of that commodity
The diagram below shows the supply curve of the individual supply schedule.
Supply schedule is defined as a table that shows various quantities of goods which producers or sellers are willing and able to place for sale in the market at different prices. For example Mrs. Bello’s Supply schedule for yams.
Price per tuber (
N) Quantity of Supplied (tubers)
From the table above, it is clear that the supplier (Mrs. Bello) supplied more at a higher price. This implies that the higher the price, the higher the quantity supplied.
The supply curve is the graphical representation of the supply schedule
Unlike the demand curve, the supply curve slopes upward from left to right. Both the supply curve and the supply schedule illustrate the law of supply, which states “the higher the price of a commodity, the higher the quantity supplied and vice versa.
FACTORS INFLUENCING THE SUPPLY OF A COMMODITY
- Price of the commodity: This is the most important factor influencing supply. The higher the price of the commodity, the higher the quantity supplied and vice versa.
- Cost of production: If the cost of producing a commodity falls, then ore of that commodity could be supplied at the existing price. It therefore means that a producer will be able to produce more commodities with the existing raw materials, hence increase in supply.
- Technological development: An improvement in the level of technology will equate to improvement in the methods or techniques of production. This will encourage large scale production at lower costs which in turn increases supply e.g. the use of modern farming techniques and equipment.
- Season:- The prevailing seasons will influence the supply of a particular commodity. E.g. More umbrellas will be supplied during the rainy season and this also applies to agricultural products.
- Government Policies: Government policies such as subsidies, restriction on importation affect the supply of goods both in the long and short run.
- Expectation of future change in prices: The expectation of suppliers about the future of the prices of some goods may affect supply. E.g. If the supplier suspects reduction in prices in future, he or she will reduce the quantity supplied of the commodity, so as to enjoy higher prices.
- Taxation: Increased taxation on goods will raise the producer’s cost of production and by extension affect the supply of the product.
- The prices of other commodities: When the prices of some commodities are high, some producers may switch over to the production of such commodities and stop producing the commodities with lower prices.
CHANGES IN QUANTITY SUPPLIED
Change in quantity supplied is only influenced by price. It involves movement along the same supply curve.
Q1 Q2 Quantity
Change in Quantity Supplied
CHANGE IN SUPPLY
Change in supply is caused by factors other than the price of the commodity. It involves a bodily shift of the supply curve either to the right (increase in supply) or to the left (decrease in supply)
Q1 Q2 Quantity Q2 Q1 Quantity
(i) Increase in supply (ii) Decrease in supply
TYPES OF SUPPLY
1. Joint Supply: Some commodities are often produced together. Such commodities come from the same source and are said to be in joint supply. Examples are petrol and kerosene, which are refined from petroleum: beef and hides from oxen.
When two commodities are in joint supply one may be a by-product of the other which means that you cannot increase the supply of one without increasing at the same time, the supply of the other.
2. Composite supply: A group of commodities may provide a composite supply to satisfy demand. For example, tea, coffee, cocoa, milk, sugar etc. provide a composite supply of beverages. This is the total supply for beverages.
3. Competitive supply: This is the supply for goods that are competitively supplied. To expand the production of one commodity generally requires a reduction in the output of another. That is, the supply of commodity A. Affects the supply of commodity B. For instance, factors of production can be used for various purposes. If a piece of land is used for growing maize, it cannot be used for building a hospital at the same time.

TOPIC – ELASTICITY OF SUPPLY
i. Meaning of Elasticity of supply.
ii. Formula for calculating Elasticity of supply.
iii. Graphical illustration of Elasticity of supply.
i. DEFINITION – Elasticity of supply can be defined as the degree of responsiveness change in quantity supplied as a result of change in price. Elasticity of supply measures the extent to which the quantity of a commodity supplied by a producer changes as a result of a little change in the price of the commodity.
ii. MEASUREMENT OF ELASTICITY OF SUPPLY – Elasticity of supply can be measured or calculated by using the co-efficient of price elasticity of supply. The formula used in calculating the elasticity of supply is :
Elasticity of supply (ES) = % change in supply
% change in price
= % QS – where
% ∆P ∆ = change
QS = Quantity supplied
P = Price
% = Percentage
The table below shows the relationship between prices of goods and the unit of commodity
Price (N) Quantity Supplied
1. Calculate the elasticity of supply when price falls from N10.00 to N9.00 State whether the supply in (iii) above is elastic or inelastic (WASSCE 1994)
Old Qty – New Qty x 100
Old Qty 1
1000 – 850 = 150
Old Quantity = 1000
New Quantity = 850
Old – New x 100
1000 – 850 x 100
150 x 100 = 15%
Old price = N10
New price = N9
Old – New x 100

Elasticity of Supply = 15 = 1.5
Elasticity is Elastic
Zero Elasticity of supply.
ES = O
2. Infinite elasticity of supply
ES = oo
3. Unitary elasticity of supply.
ES = 1
4. Elastic supply
oo > ES > 1
Inelastic or fairly inelastic supply curve.
EXCEPTIONAL (ABNORMAL) SUPPLY CURVE
As a general rule, supply curve slopes upwards from left to right showing that at higher prices more of the
commodity will be supplied. A normal supply curve has a positive slope.
However there are cases when this normal condition does not hold. In such cases, the supply curve will
slope downwards from left to right.
Abnormal or exceptional supply curves otherwise known as regressive supply curves are manifested in the
1. The fixed supply: Some goods or productive factors are completely fixed in amount regardless of their prices. An example is land.
2. Backward-sloping supply: This is a situation where a portion of the supply curve will slope backward from left to right. This is usually associated with the supply of labour.
Number of hours worked

When p = N7 Qs = 12 + 4 (7)
Qd = 42 – 2 (7) = 12 + 28
= 42 – 14 = 40 units
When p = N8 Qs = 12 + 4(8)
Qd = 42 – 2 (8) = 12 + 32

iv. Derivation of equilibrium price and quantity from demand and supply functions.
v. Effects of changes in demand and supply on equilibrium price and quantity
FREE MARKET ECONOMY
A free market is a market in which prices of goods and services are regulated by market forces. This means that prices of commodities in a free market economy are fixed by the interaction (i.e. joint actions) of demand and supply.
DETERMINATION OF PRICES IN A FREE MARKET
It is possible to compare demand with supply by drawing a schedule showing the quantity of goods demanded and supplied. An example of a combined demand and supply schedule is shown below.
N Quantity demanded (units) Quantity supplied (units)
7 100 900
6 200 700
5 300 650
4 400 400
3 500 300
2 600 250
1 700 200
The schedule above can be graphically represented by the curve below.
EQUILIBRIUM POINT, EQUILIBRIUM PRICE AND EQUILIBRIUM QUANTITY
Given a downward sloping demand curve and an upward sloping supply curve as in the diagram above, there would occur a unique point of intersection indicating a price level at which quantity supplied will be equal to the quantity demanded. Such point of intersection is called an equilibrium point and when such point is traced to the price and quantity axis of the graph, we shall obtain the equilibrium price and equilibrium quantity bought and sold respectively.
From the graph above, the equilibrium point was established at point A and when traced to the price and quantity axis, it showed the market equilibrium price and equilibrium quantity bought and sold of
N4 and 400 units respectively.
The equilibrium price is the price at which the quantity of goods demanded is equal to the quantity supplied. This price is determined by the interaction of supply and demand
At a price lower than the equilibrium price (say
N2) demand will be greater than supply. This will lead to shortage of goods in the market that is, excess demand. On the other hand, at a higher price than the equilibrium price (say N6), producers will supply more than the consumers are willing to buy and this will lead to an excess supply – i.e surplus of goods in the market.
Derivation of equilibrium price and quantity from demand and supply functions
Given the Demand and supply functions:
Qd = 42-2p and Qs =12+4p
Determine the equilibrium price and equilibrium quantity
At equilibrium price
Qd = Qs
i.e. 42- 2p = 12+4p
42-12 = 4p +2p
30 = 6p
P= 30/6 = 5
Equilibrium price =
To obtain the equilibrium quantity
Substitute for p in
Qd = 42 –2p
Qd = 42 – 2 (5)
= 42 –10
Equilibrium Quantity = 32units
EFFECTS OF CHANGES IN DEMAND AND SUPPLY ON EQUILIBRIUM PRICE AND QUANTITY
Changes in demand and supply lead to a change in the equilibrium price. Once there is any change in either demand or supply, the initial equilibrium will be disrupted and a new equilibrium will be created. The market equilibrium price can be affected in the following ways.
Increase in Demand
Effects of increase in demand
- Increase in the equilibrium price from P1to P2
- Increase in the equilibrium quantity from Q1 toQ2
2. Decrease in demand
Effects of Decrease in demand
- Decrease in the equilibrium price from P1 to P2
- Decrease in the equilibrium quantity from Q1to Q2
3. Increase in Supply
- Decrease in the equilibrium price from P1 to P2

TOPIC: PRICE SYSTEM OR PRICE MECHANISM
1. The concept of price system or price mechanism
2. Factors that determine price of commodities
3. Government interventions in the market
4. Price control
PRICE SYSTEM OR PRICE MECHANISM
In a free market economy prices of goods and services affect the behaviour of both the consumer and the producer (supplier) Price system maybe defined as a system whereby prices of goods and services are determined by the free interaction of the forces of demand and supply in a free market economy.
FUNCTIONS/IMPORTANCE OF THE PRICE SYSTEM
1. The price system operates to allocate scarce resources
2. It regulates the flow of goods and services from producers to the consumer.
3. It determines the extent of demand and supply of goods and services.
4. It is used to encourage or discourage consumption of certain goods and services.
5. It helps to determine how the factors of production will be rewarded.
FACTORS THAT DETERMINE PRICE OF COMMODITIES
a. The cost of production of the product
b. The level of profit desired by the seller
c. The level of competition in the market
d. Government policies e.g subsidies, taxation etc.
e. The activities of Trade Unions
f. The cost incurred on advertisement
g. Changes in demand and supply
GOVERNMENT INTERVENTIONS IN THE MARKET
Sometimes government intervenes in the market through subsidies and direct price control.
a. SUBSIDIES: Government may pay a part of the cost of certain products on behalf of the consumer. This is usually in the form of granting concessions to the producers to assist them in cutting production costs e.g through the reduction of import duties on inputs – machinery or raw materials.
b. PRICE CONTROL: Price control defines a situation where the government uses the instrument of law to fix the price of certain commodities. It can be in the form of maximum or minimum price control.
i. Maximum price control: This is practiced when government wants to protect consumers against suppliers (sellers). The government will set a maximum price below the market equilibrium price of the commodity.
Effects of a maximum price control policy
a) Hoarding of goods
b) Stimulation of demand i.e. excess demand, which cannot be satisfied.
c) Shortages of goods in the market
d) Queues for the good concerned
e) Black market dealing/under –counter sales
f) Reduction in supply
g) Rationing of the good
h) Favoritism, bribery and corruption
ii) Minimum price control: This happens when the government wants to protect infant industries or inefficient home producers against outside competition. The government will set a minimum high price above the market equilibrium price for the good and in addition may also saddle importers with a high duty.
The increase in price will however reduce demand and create a surplus in the market. The government will then step in again to buy up the surplus goods and store them to meet the shortages in supply in the future
OBJECTIVES OF PRICE CONTROL POLICY
1. To prevent exploitation of consumers by producers and sellers
2. To avoid or control inflation
3. To help low income earners e.g the minimum wage policy
4. To control the profits of companies –especially monopoly.
5. To prevent fluctuations of prices of some products e.g agricultural produce.
6. To stabilize the income of some producers e.g. farmers.
7. To enhance possible planning for future output.
1. List two importance of the price system.
2. Explain how government policy and taxation can affect price determination.

- Definition and Scope of public finance
- Functions or objectives of public finance
- Sources of government revenue
- Items of government expenditure
- Classification of government revenue and expenditure
- Reasons for increase in government expenditure.
Public finance is the management and control of government income and expenditure to achieve government’s policy objectives.
It involves a detailed analysis of the various sources from which the government derives its income (revenue), the items on which the government spends its money and the impact of such government expenditure on different aspects of the economy.
FUNCTIONS / OBJECTUIVES OF PUBLIC FINANCE
- It performs equitable distribution of resources among individual, tiers of government and the various sectors of the economy.
- It is use to achieve and maintain favourable balance of payments and economic development.
- It provides a general parameter for monitoring the economy in terms of growth and stability.
- It is used to achieve the economic objectives of the government.
- It provide fund for transfer payments e.g pension fund, unemployment benefits, subsidies etc.
SORCES OF GOVERNMENT REVENUE
The main sources of government revenue are
- Taxes: This forms a major source of revenue to governments all over the world. These taxes may be direct or indirect taxes.
- Royalties – This is the money paid by companies engaged in mining activities to the government for rights to explore and exploit mineral resources deposits
- Earning (income) from government investments e.g. interest, rent, dividends, profits from government owned business property.
- Grants and aids from individuals and institutions at home and from foreign governments and international organizations.
- Borrowing:- This could be internal or external borrowing e.g sale of government securities or loans from African Development Bank, IMF, World Bank, Pars Club etc
- Fees, licenses and charges, fines etc eg vehicle licence fees, liquor licence fees, fire arms licence fees, international passport fees, court fines, Road Safety Commission fines etc
- Other sources e.g. Tolls, rates etc.
The main items of government expenditure are
- Defence or National Security: The government provides for the Army, Air force, Navy and the Police to maintain law and order and defend the country from external aggression.
- General Administration: The government spends money in maintaining the Civil Service and the various officers of the government in the ministries, agencies, corporations, parastatals and departments
- Social, educational facilities, water supply pipe borne water etc and pension benefits for retires.
- Economic Infrastructure e.g roads, bridges ports, agriculture telecommunication, power and electricity etc.
- Servicing of the National Debt: i.e. the repayment of the principal and interest of both external debts
- Direct Productive Service: Government sometimes participate directly by organizing productions of some commodities.
CLASSIFICATION OF PUBLIC REVENUE
Government revenue can be classified as
- Recurrent Revenue:/ This is the total amount of revenue collected by the government of a country from their regular or yearly basic e.g taxation, fees, licences, fines etc.
- Capital Revenue:- These are revenue from irregular or extraordinary sources. They are sources of revenue used for meeting expenditure on heavy capital projects e.g grants or loans collected by the government for the purpose of building a project e.g railway line.
CLASSIFICATION OF PUBLIC EXPENDITURE
Government expenditure can be classified as:
1. Recurrent Expenditure: – These are expenditure incurred in the running of the day to day activities of the government. They are expenses that re-occur within a fiscal year i.e. items / expenses that last for less than a year e.g wages, salaries, stationery, fuel for official cars, cost of maintaining roads, repairs expenses on dams etc.
2. Capital Expenditure:- These are expenditure (investments) on project that last for more that one year. They are used to acquire assets that are of permanent nature e.g construction of roads, bridges, government buildings, purchase of cars etc.
In most cases, recurrent expenditure is spent in maintaining capital projects.
REASONS FOR INCREASE IN GOVERNMENT EXPENDITURE
There has been an astronomical increase in the magnitude of government expenditure. Some of the reasons for this include:
- Increase in population leading top higher administration costs
- The effect of inflation (general increase in price level) on the cost of projects undertaken by the government.
- The effect of devaluation (depreciation) of the Naira on a largely import dependent economy of Nigeria.
- The increasing cost of maintaining democratic institutions and large number of political structures i.e. states, local governments and their officials.
- Greater demand for social and economic infrastructures and the cost of maintaining existing ones.
- The developmental / industrialization programmes of the government requires a lot of capital outlay to import the needed equipment / machines
- The cost of servicing the country’s huge stock of internal and external debt which has kept increasing because of interest capitalization
- The high prevalence of corruption and over invoicing of the cost of projects by government officials and politicians.
A fiscal policy may be defined as a government plan of action concerning the raising of revenue through taxation and other means and deciding the pattern of expenditure to be applied.
Fiscal policy therefore involves the use of government income and expenditure instrument to regulate the economy with the aim of achieving some set economic objectives
The economic objectives of the government on fiscal policy includes.
1. Maintenance of stable prices / control of inflation and deflation.
2. Equitable distribution of wealth
3. Efficient allocation of resources
4. Provision of full employment
5. Stability in the exchange rate of the national currency
6. Maintenance of favorable balance of payments
1. Explain any two items of government expenditure
2. Distinguish between capital Expenditure and Recurrent Expenditure.

- Reasons for the imposition of taxes
- The principles of taxation
- The concepts of tax base and tax rate
- Forms (Systems) of income tax
- Problems associated with tax collection in Nigeria.
A tax is a compulsory payment made by each eligible citizen towards the expenditure of the country. It is a compulsory contribution imposed by a government authority on goods, individuals, corporate bodies (business) without regard to the specific benefits that the taxpayer may receive.
REASON FOR THE IMPOSITION OF TAXES BY THE GOVERNMENT
- To raise revenue for the government
- Taxation is used to redistribute income i.e. to lower / reduce the income gap between the rich and the poor.
- To project infant industries – infant industries are newly formed industries that has to be protected from competition by already established industries.
- To stop or discourage the importation of dangerous or harmful goods e.g cigarettes
- Taxation is used as a fiscal device to control the economy i.e. to control inflation, deflation or influence the rate of consumption, investments and savings in the economy
- To encourage industrialization e.g by tax rebates or tax holidays for industrialists
- Taxes are also used to promote social services such as social insurance, poor and elderly relief, health insurance etc.
PRINCIPLES OF TAXATION
Adam Smith in his book Wealth of National lays down four canons or attributes of a good tax system. They are
- Equity: This principles emphasizes that the tax imposed must be in consonance with the tax payer’s ability to pay. In other words, the tax imposed should be in fair proportion to the taxpayer’s income. The progressive tax system reflects this.
- Certainly: The tax payer must know how much he / she is to pay, in what medium, where, when and how the tax is to be paid.
- Convenience: The method and time of tax collection should be convenient to the tax payer e.g wage/salary earners at the end of the month, farmers during harvesting period etc.
- Economy: The cost of collection of taxes should be small relative to the amount collected. It will neither be frugal not prudent to use resources of N10,000 to collect
In addition to the above, the following principles of a good tax system should be noted.
5. Flexibility: A good tax system should be capable of being changed when conditions and situations warrant such changes.
6. Neutrality: A good tax system should not be a disincentive to enterprise or productively i.e. it should not interfere unnecessarily with the supply and demand for goods, services and labour.
7. Simplicity: A good tax system should be simple enough for easy understanding.
8. Impartiality: There should be no discrimination in the collection of taxes.
9. Difficult to evade: A good tax system should ensure that tax evasion / tax avoidance are kept at a minimum.
CONCEPT OF TAX BASE AND TAX RATE
The tax base refers to the item of the object which is taxed. i.e. the amount of the salary wages, income, profits, gains or assets upon which the calculation of tax to be paid is based
The tax rate refers to the percentage that is applied to the tax base in order to calculate the amount of tax payable by the taxpayer.
SYSTEMS OF TAXATION / FORMS OF INCOME TAX
- Proportional Tax: This is a form of income tax in which the same rate of tax is applied to the respective income of taxpayers. for example if government applies a tax rate of 10% on all taxpayer income, a worker earning N15,000 will pay N1500 tax will pay N6000 as tax.
- Progressive Tax: In this case, the percentage levied (tax rate) increases with the size of one’s income. A progressive tax takes a larger percentages of income from people with larger income. It reduces inequality of income from people with larger income. It reduces inequality of income distribution eg Pay As You Earn (P.A.Y.E.)
- Regressive Tax: In this case, the proportion removed as tax from one’s income decreases as the person’s income increases i.e. The higher the income, the lower the rate of tax eg Poll tax, indirect tax etc. A regressive tax aggravate inequality of income distribution
PROBLEMS ASSOCIATED WITH TAX COLLECTION IN NIGERIA
- Corruption and non challant attitudes of revenue officers / tax collectors.
- Tax evasion and Tax avoidance
- Lack of proper accounting records by business enterprises
- Ignorance / illiteracy / mass poverty of the populace
- Apathy of tax payers as a result of corruption in high places
- Government’s inability to provide essential infrastructure and amenities eg electricity does not encourage people to pay tax.
TAX EVASION AND TAX AVOIDANCE
Tax Evasion refers to an illegal attempt not to pay tax or pay less tax. For instance, someone could make false declarations of income or tax could be dodged completely.
Tax Avoidance refers to the efforts of a tax payer not to pay tax by finding a legal 100phone in the tax system. For example, the taxpayer could discover a part of the tax law that is ambiguous. He can therefore take advantage of this and easily defend himself legally if he does not pay tax or if he pays less tax. Tax avoidance is a legal etc.

(2) Advantages and disadvantages of direct and indirect tax
(3) Economic effects of taxes
(4) Incidence of taxation
(5) Objectives of taxation
FORMS OF TAX
Taxes are divided into broad categories namely direct taxes and indirect taxes
(i) Direct tax: This is a tax collected from individuals and profits of companies. The burden of direct tax is borne by the payer.
Examples of direct taxes are (a) income tax (b) Company tax (c) Capital gain tax (d) Poll tax etc.
ADVANTAGES OF DIRECT TAXES
1. They are progressive in nature
2. The incidence of direct tax is easy to ascertain
3. They are easy to calculate
4. Payers find them convenient to pay
5. Some specific group of people or business could be granted exemption from payment of direct tax.
DISADVANTAGES OF DIRECT TAXES
1. They discourage savings
2. They discourage investments
3. They are difficult to assess (determined with accuracy) eg company tax.
4. Cases of tax evasion is high (frequent)
5. They discourage hard work
6. It may result to squabbles between taxpayers and tax officials
(ii) Indirect Tax: This is a tax levied on goods and services. They are initially paid by either the manufacturer or importer of the goods who, as far as possible shifts the burden to the consumers in form of high prices. Examples of indirect taxes are customs duties (import duty and export duty) excise duty, purchase tax etc.
ADVANTAGES OF INDIRECT TAXES
a. Their collection is less difficult
b. They cause less squabbles
c. It yields more revenue to the government than direct taxes.
d. They are not easy to evade
e. The burden is shared among all sections of the society.
DISADVANTAGES OF INDIRECT TAXES
1. It causes inflation i.e. increases in the prices of goods.
2. It may cause scarcity of goods
3. They are unreliable sources of revenue
4. Indirect taxes are regressive in nature
5. They are non-discriminatory i.e. some group of people cannot be granted exemption from paying.
6. They restrict free trade between different countries.
DIFFERENCE BETWEEN SPECIFIC TAX AND AD VALOREM TAX.
This reflects the different methods of calculating custom duties.
In Specific Tax, the amount of tax to be paid depends on the quality of goods bought so that the greater the quality of goods bought the greater the tax to be paid.
Ad Valorem Tax: The amount of tax to be paid depends on the value or quality of the commodity. This value or quality is measured in terms of the price of the commodity. This means that goods which have higher prices are supposed to have higher values and are therefore taxed more heavily than goods whose values and thus prices are lower.
ECONOMIC EFFECTS OF DIRECT TAXES
- Direct taxes lead to a reduction in disposable income and consequently a reduction in consumption.
- It discourages savings
- It discourages hard work
- It discourages investments and this would, in turn cause unemployment.
- It leads to a redistribution of wealth
- It reduces capital available for a company in form of retained profits.
ECONOMICS EFFECTS OF INDIRECT TAXES
- It can lead to inflation
- It encourages smuggling
- It reduces production e.g. excise duties thereby causing scarcity of goods.
- It discourages investment
- It can lead to changes in the consumption pattern i.e. it alters the demand and supply of goods.
INCIDENCE OF A TAX
The incidence of a tax refers to the burden of tax with reference to where this burden rests. The incidence or burden of taxation lies on the person who finally pays the tax. There are two types of tax incidence
a. Formal incidence: this refer to where the in initial burden of taxation lies. The payer of a direct tax bears the initial burden of tax. For indirect taxes, the producers or the middlemen bears the initial burden of taxation.
b. Effective incidence: This refers to who bears the ultimate or final burden of taxation. In the case of direct taxes the payer bears the full burden of taxation. He bears both the formal and effective incidence.
In the case of indirect taxes, the burden of taxation may be borne by the producer (seller) or the consumer, or it may be shared between the producer (seller) and the consumer. The extent to which the producer (or seller) or the consumer will bear the burden of indirect tax will depend on the elasticity of demand for the commodity which is taxed.
1. Where the demand for the commodity is perfectly inelastic, the whole tax burden can easily be shifted to the consumer by the seller.
2. Where the demand for the commodity is perfectly elastic, the seller or producer will bear the whole burden of taxation. This is because any attempt to increase prices will make the demand for the commodity to fell to zero. The tax burden cannot, therefore be passed to the consumer.
3. Where the elasticity of demand for the commodity is unitary, tax burden is shared equally between the producer / seller and the consumer.
4. Where the elasticity of demand for the commodity is moderately elastic or moderately inelastic, the burden of taxation will be shared between the producer (seller) and the consumer depending on the extent of the elasticity.
1. Define the term – formal incidence of tax
2. Shoe with the aid of a diagram, who bears the incidence of tax of a commodity having inelastic demand.
1. A tax on a commodity whose demand is perfectly inelastic will fall heavily on the (A) Consumer (B) manufacturers (C) wholesalers (D) retailers.
2. Government revenue will increase if tax is imposed on a good whose demand is (A) elastic (B) inelastic (C) unitary elastic (D) perfectly elastic.
3. Which of the following is an indirect tax (A) income tax (B) company tax (C) Profit tax (D) Sales tax.
4. A tax whose rate increases as income increases is (A) an indirect tax (B) a progressive tax (C) a regressive tax (D) a proportional tax.
5. The largest part of the revenue of a country is derived from (A) direct taxation (B) indirect taxation (C) excise duties (D) company taxes.

TYPES OF BUDGET
1. Balance Budget: This is when the total estimated revenue is equal to the proposed expenditure of the government. This means that nothing will be left as reserve from the money collected in form of revenue
2. Surplus Budget: A budget is called surplus budget when the total estimated revenue is more than the proposed expenditure. In this type of budget, not all the estimated revenue is proposed to be spent in that year. That is, there will be reserve.
3. Deficit Budget: This is when the government total proposed expenditure for the period is more than the total estimated revenue. The shortfall in revenue is sourced through borrowings, printing of more currency, aids and grants etc.
Economic conditions warranting the adoption of the different types of budgets
1. A budget surplus is desirable in period of inflation because it reduces aggregate demand thereby reducing inflationary pressure in the economy
2. A deficit budget is used in the following instances
(a) To reduce unemployment by increasing aggregate demand.
(b) To finance a national emergency such as war
(c) To remedy a deflationary trend.

- Meaning of Revenue Allocation
- Parts of Revenue Allocation
- Revenue Allocation formula.
(I) MEANING OF REVENUE ALLOCATION
Revenue allocation refers to the sharing of the nation’s wealth among various tiers of government or various units that make up the country. The various units include: Federal, State and local governments.n
PARTS OF REVENUE ALLOCATION
Revenue allocation is grouped to two major parts namely:
1. Vertical Revenue Allocation
2. Horizontal Revenue Allocation
1. Vertical Revenue Allocation – In vertical revenue allocation, revenue accruing to the Federal Account is shared among the three tiers of government – Federal, State and Local government.
2. Horizontal Revenue Allocation – Under the Horizontal Revenue Allocation, revenue accruing to federation account is shared among the units within a given level of government. It involves certain principles based on some factors to be applied in revenue allocation. These principles include:
1. Population size
2. Land mass
3. Derivation, Oil producing areas.
4. Ecological problems.
REVENUE ALLOCATION FORMULA
This involves the weight assigned to various principles e.g. Federal government – 40%, State – 20%, Local government – 15%, mineral producing area – 10%, ecological problems – 5%, special fund – 5% others – 7%. These are just for the short time. It should be noted that there is no fixed revenue allocation. It changes from time to time. The Revenue mobilization Allocation and Fiscal Commission (RMFC) is always at work trying to work out a proposal for a new revenue sharing formula.
