Keypoints: The Theory of Price Determination; The Theory of Price Determination is a fundamental concept in economics that seeks to explain how the price of a good or service is determined in a market. It is based on the interaction of demand and supply forces in the market, and it helps to explain why prices fluctuate over time as market conditions change.
The theory of price determination is crucial in understanding how businesses make pricing decisions and how policymakers regulate markets to achieve specific economic outcomes.

Keypoints: The Theory of Price Determination
a. The concepts of market and price
A market is a platform where buyers and sellers interact to exchange goods and services for a price. The price, in turn, is the monetary value that a buyer pays for a good or service. The price is determined by the interaction of supply and demand forces in the market.
b. Functions of the price system
The price system serves several critical functions in a market economy. Firstly, it acts as a signal to buyers and sellers about the relative scarcity or abundance of goods and services. Secondly, prices act as incentives for producers to allocate resources efficiently by producing goods and services that are in high demand. Thirdly, prices help to allocate resources between different sectors of the economy.
c. i. Equilibrium price and quantity in product and factor markets
The equilibrium price and quantity are the price and quantity at which the supply of goods and services equals the demand for goods and services in the market. In the product market, equilibrium price and quantity are determined by the interaction of the supply of the product and the demand for the product. In the factor market, the equilibrium price and quantity are determined by the interaction of the demand for and supply of factors of production such as labor, capital, and land.
c. ii. Price legislation and its effects
Price legislation is government intervention in the price system, typically to control the price of goods and services. Price controls can take the form of maximum or minimum prices. Maximum price legislation, also known as price ceilings, is a legal limit on the price of a good or service. Minimum price legislation, also known as price floors, is a legal minimum price below which the price of a good or service cannot be sold. Price legislation can lead to market distortions, including shortages, surpluses, and black markets.
d. The effects of changes in supply and demand on equilibrium price and quantity
Changes in supply and demand can lead to changes in the equilibrium price and quantity. If the supply of a good or service increases, ceteris paribus, the price of the good or service will decrease, and the quantity will increase. Conversely, if the demand for a good or service increases, ceteris paribus, the price of the good or service will increase, and the quantity will increase. If there is a decrease in either supply or demand, ceteris paribus, the opposite effect will occur. These changes in the equilibrium price and quantity reflect the dynamic nature of the price system in responding to changes in market conditions.
In summary, the theory of price determination is a critical concept in economics that helps us to understand how prices are determined in a market economy. Understanding the concepts of market and price, the functions of the price system, the equilibrium price and quantity in product and factor markets, the effects of price legislation, and the effects of changes in supply and demand on equilibrium price and quantity are fundamental to understanding the workings of the market economy.
i. Explain the concepts of market and price:
- A market is a place where buyers and sellers come together to exchange goods or services.
- The price is the amount of money that a buyer pays to a seller in exchange for a good or service.
ii. Examine the functions of the price system:
- The price system performs several functions in a market economy, including allocating resources efficiently, coordinating the actions of buyers and sellers, transmitting information about supply and demand, and providing incentives for producers and consumers to respond to changing market conditions.
iii. Evaluate the effects of government interference with the price system:
- Government interference with the price system can lead to market distortions and inefficiencies, as well as unintended consequences. For example, price floors and price ceilings can create surpluses or shortages in the market, leading to inefficient resource allocation.
iv. Differentiate between minimum and maximum price legislation:
- Minimum price legislation sets a floor price below which the price of a good or service cannot fall, while maximum price legislation sets a ceiling price above which the price cannot rise.
v. Interpret the effects of changes in supply and demand on equilibrium price and quantity:
- When there is a change in supply or demand, the equilibrium price and quantity of a good or service will adjust accordingly. If there is an increase in demand or a decrease in supply, the equilibrium price will increase, and the equilibrium quantity will decrease. Conversely, if there is a decrease in demand or an increase in supply, the equilibrium price will decrease, and the equilibrium quantity will increase.
