Normal Profit, Supernormal Profit & Losses
-
When calculating costs, Economists consider both the explicit and implicit costs of production
-
Explicit costs are the costs which have to be paid e.g raw materials, wages etc.
-
Implicit costs are the opportunity costs of production
-
This is the cost of the next best alternative to employing the firm’s resources
-
E.g. if an investor puts £1m into producing bicycles & they could have put it in the bank to receive 5% interest, then the 5% represents an implicit cost
-
-
Implicit costs must be considered, as entrepreneurs will rationally reallocate resources when greater profits can be made elsewhere
-
-
Profit = total revenue (TR) – total costs (TC)
-
Total costs include explicit and implicit costs
-
-
Normal profit occurs when TR = TC
-
This is also called breakeven
-
-
Abnormal (supernormal) profit occurs when TR > TC
-
A loss occurs when TR < TC

Observations
-
Supernormal profit occurs up to the 6th unit of output
-
Normal profits occur at the 7th unit
-
From the 8th unit, the firm is making a loss
The role of Profit in a Market Economy
-
Profit plays a central role in a market economy
1. Profit is an incentive for innovation and entrepreneurship
-
Profit serves as a reward for successful entrepreneurship and innovation
-
Entrepreneurs take on risks to start businesses or develop new products/services with the expectation of making a profit
-
It encourages individuals to innovate, leading to economic growth and improved standards of living
2. Allocation of resources
-
In a market economy, profit serves as a signal for resource allocation
-
When businesses earn profits, it indicates that they are meeting consumer demands efficiently
-
This encourages the reallocation of resources (capital, labour, and land) towards the production of goods and services that consumers value most, thereby enhancing economic efficiency
3. Competition
-
Profit serves as a measure of business success and efficiency
-
In a competitive market, firms strive to maximise profit by improving productivity, lowering costs or enhancing the quality of goods and services
-
This competition benefits consumers by providing them with better products at lower prices
4. Economic growth
-
Profitable businesses reinvest their earnings into expanding operations, research and development, and hiring more workers
-
This investment stimulates economic growth, creates jobs, and generates technological advancements
5.Wealth creation
-
Profit generation leads to wealth creation for businesses, shareholders, and employees
-
It enables businesses to accumulate capital, which can be reinvested or distributed to shareholders as dividends
-
Employees also often benefit from profit-sharing schemes or performance-based bonuses
-
It is essential to recognise that excessive focus on profit maximisation without considering social and environmental factors can lead to negative externalities, such as environmental degradation, income inequality, or exploitation of labour
-
While profit is a crucial driver of economic activity, it should be pursued within the framework of ethical and sustainable business practices
