Definition of Price System:

Price system is a component of any economic system, that uses prices expressed in any form of money, for the valuation and distribution of goods and services, and the factors of production, to determine the rate at which goods and services are produced, distributed, and exchanged.

It can also be referred to as the Price mechanism.

The prices are fixed by buyers and sellers through negotiation. Price in a perfect market is determined by the interaction of the forces of supply and demand, in relation to the conditions of demand and supply. The interaction of the forces of demand and supply is where demand is equal to supply, which has to do with the negotiation of buyers and sellers on the price of goods and services. 

Functions of Price System:

2. Indicates changes in demand.

4. Determine income received by factors of production.

5. It indicates the distribution among consumers (i.e. firms and private, etc).

6. Regulates production for current and future purposes.

7. It can determine the quantity and quality of goods produced.

Importance of Price System:

1. Freedom to buy and sell.

3. Freedom of choice and employment.

4. Freedom to private ownership.

Question 1

The following table shows the number of oranges that would be bought and sold at the prices shown:

Price (₦) per orange Quantity of oranges sold Quantity of oranges bought
10 1000 400
8 800 500
6 600 600
4 400 700
2 200 1000

 

(a) What is the equilibrium price and quantity?

Answer – The equilibrium price is 6 and the equilibrium quantity is 600 units.

(b) At what price does the market exhibit excess demand?

Answer  Excess demand = Qd –Qs

4, excess demand 700-400 = 300units

2, excess demand 1000-200 = 800units

(c) At what price does the market exhibit excess supply?

Answer – Excess supply = Qs – Qd

10, excess supply 1000 – 400 = 600units

8, excess supply 800 – 500 = 300units

Question 2

State the law of supply

The law of supply states that the higher the price of a commodity, the higher the quantity supplied or vice versa

Question 3

With illustration explain the supply Schedule. 

Supply schedule: It is a table that shows the quantity of a commodity that is offered for sale at any given price and at a given period of time. This is illustrated as shown below:

Supply schedule for orange

Price () Quantity supplied (kg)
5 500
4 400
3 300
2 200
1 100

 

From the table above, it can be seen that more oranges were supplied at a higher price than at a lower price.
