Theory of Production
Production refers to the various economic activities involved in creating goods and services and making them available to final consumers for the satisfaction of human wants. All goods and services produced must possess utility, meaning they must be capable of satisfying human needs.
Production is regarded as complete only when the goods and services produced reach the final users or consumers.
Types of Production
Production can be classified into two major categories:
- Direct Production
- Indirect Production
Direct Production
Direct production is a type of production in which an individual produces goods and services solely for personal or family consumption. The goods produced are usually small in quantity and are not meant for sale.
Indirect Production
Indirect production involves the large-scale production of goods and services mainly for sale or exchange. It requires the use of modern equipment and skilled labour.
Indirect production is further divided into three main categories:
- Primary Production
- Secondary Production
- Tertiary Production
Primary Production
Primary production involves the extraction of raw materials directly from nature. It focuses on obtaining natural resources from land, water, and air. Examples include agriculture, mining, fishing, lumbering, and hunting.
Secondary Production
Secondary production involves the processing and transformation of raw materials obtained from primary production into finished or semi-finished goods that are acceptable to consumers. It includes manufacturing and construction activities such as making clothes, processed food, houses, vehicles, and machinery.
Tertiary Production
Tertiary production is concerned with the provision of services that assist in the distribution of goods produced at the primary and secondary levels. It also includes professional services. Examples include wholesalers, retailers, transporters, as well as professionals such as doctors, teachers, lawyers, police officers, soldiers, musicians, and others.
Types of Goods
Economists classify goods and services that satisfy human wants into three main groups:
Consumer Goods and Services
These are goods and services that directly satisfy consumers’ immediate needs and wants. They are classified into:
- Durable Goods: Goods that can be used repeatedly over a long period of time before wearing out, such as radios, televisions, cooking utensils, tables, and clothes.
- Non-Durable Goods: Goods that are perishable or used up after a single or short period of use, such as food items, drugs, milk, bread, and eggs.
Capital or Producer Goods
Capital goods are man-made goods used in the production of other goods and services. They are demanded not for direct consumption, but for their contribution to further production. The purchase of capital goods is referred to as investment. Examples include machines, tools, factories, vehicles, and buildings.
Public Goods
Public goods are goods and services provided by the government for the benefit of all members of society without exclusion. Examples include national defence, police services, street lighting, roads, and environmental protection.
Economies of Scale (Scale of Production)
Economies of scale refer to the expansion of a firm as a result of increasing the capital employed in order to increase output and reduce the cost per unit of production. An increase in output implies an increase in the scale of production.
Capital employed refers to the purchase of fixed assets such as machinery, plants, and equipment by a firm.
Types of Economies of Scale
Economies of scale are broadly classified into:
- Internal economies and internal diseconomies
- External economies and external diseconomies
Internal Economies and Internal Diseconomies of Scale
Internal Economies of Scale
Internal economies of scale are the advantages a firm enjoys as a result of an increase in its size and output. These advantages lead to a reduction in the average cost of production as output increases. Internal economies are also known as the economies of large-scale production.
Types of Internal Economies of Scale
- Purchasing Economies: Large firms can buy raw materials in bulk and enjoy discounts as well as efficient bulk delivery.
- Marketing Economies: Large firms can afford their own transport systems and use various advertising media to promote their products.
- Financial Economies: Large firms can borrow money more easily and at lower interest rates because they can provide assets as collateral or raise funds through the sale of shares.
- Technical Economies: Large firms can use modern machinery and employ technical experts, resulting in higher productivity.
- Risk-Bearing Economies: Large firms can reduce risks by producing a wide range of products and operating in different geographical areas.
Internal Diseconomies of Scale
Internal diseconomies of scale arise when a firm becomes too large or expands too rapidly, leading to inefficiency. As a result, productivity may decline and the cost per unit of output may increase.
- Management Diseconomies: Managing large firms with multiple branches and diverse products may become difficult.
- Capital Constraints: Large firms may require huge amounts of capital and raw materials, and shortages can disrupt production.
- Labour Diseconomies: Workers may become demotivated due to repetitive tasks, leading to conflicts, disputes, or strikes.
- Merging Diseconomies: Conflicts may arise between owners when firms merge to form a large-scale enterprise.
External Economies and External Diseconomies of Scale
External economies of scale are the benefits a firm enjoys as a result of the concentration of many firms or industries in a particular location.
Examples of External Economies
- Availability of a skilled labour force trained by nearby firms.
- Location of ancillary firms that supply specialized equipment and services.
- Shared infrastructure such as roads, water supply, and power facilities.
Law of Diminishing Returns (Law of Variable Proportions)
The Law of Diminishing Returns, also known as the Law of Variable Proportions, states that when additional units of a variable factor of production (such as labour) are continuously applied to one or more fixed factors (such as land), total output may increase rapidly at first. However, beyond a certain point, the additional output obtained from each extra unit of the variable factor will begin to decrease, and eventually total output may decline.
This law is particularly applicable to both the agricultural and industrial sectors of the economy.
Merits of the Law of Diminishing Returns
- It helps in achieving the proper combination of factors of production.
- It assists entrepreneurs in adjusting the scale of production by varying the quantity of inputs used.
- It promotes efficiency, higher productivity, and maximum profitability in the production process.
- It helps to prevent wastage of resources, thereby reducing the cost of production.
- It enables producers to determine the point at which adding more variable factors will no longer increase output.
Division of Labour
Division of labour refers to the process of breaking down a production activity into several distinct operations, with each operation performed by a different worker or group of workers.
For example, in the publishing industry, division of labour exists where different workers are responsible for writing manuscripts, editing, filming and plating, printing, folding, collating, sewing, binding, and finally trimming.
Specialisation
Specialisation is the concentration of the productive efforts of an individual, firm, or country on a particular economic activity in which it has the greatest advantage.
Division of labour is a form of specialisation. In fact, specialisation results from division of labour.
Advantages of Division of Labour and Specialisation
- Increase in Production: Experts working on different stages of production increase overall output.
- Saving of Time and Energy: Workers save time and effort by concentrating on a single task rather than switching between different operations.
- Development of Skills: Repetition of the same task enables workers to gain higher levels of skill and efficiency.
- Lower Unit Cost: Increased productivity leads to lower cost per unit of output.
- Encourages Specialisation: Workers become specialists in specific tasks, improving quality and efficiency.
Disadvantages of Division of Labour and Specialisation
- Monotony: Repeating the same task daily can make work boring and reduce workers’ interest.
- Decline in Craftsmanship: Increased use of machinery reduces the use of individual skills in production.
- Reduction in Employment Opportunities: Machines often replace workers, leading to unemployment.
- Limited Labour Mobility: Workers may find it difficult to switch to other jobs after long periods of specialization.
- Increased Interdependence: Production depends on the cooperation of all workers; absence of one may disrupt the process.
Limitations to Division of Labour
- Size of the Market: A small market limits division of labour because it cannot absorb large-scale output.
- Nature of the Product: Some products cannot be easily divided into different stages of production.
- Level of Technology: The extent of specialisation depends on the level of technological development.
- Availability of Capital and Labour: Adequate capital and skilled labour are required to support division of labour.
