COST OF PRODUCTION

The cost of production is an essential concept in economics that refers to the total expenses incurred in the production of goods and services. It includes the cost of raw materials, labour, rent, and other expenses required to produce goods and services. The cost of production is crucial in determining the price of goods and services, and it has a significant impact on the profitability of businesses. In this blog post, we will explore the concept of the cost of production, its types, and the factors that affect it.

Types of Cost of Production

There are various types of cost of production, including the following:

  1. Fixed Costs: Fixed costs are expenses that do not vary with the level of output, such as rent, insurance, and salaries of permanent employees.
  2. Variable Costs: Variable costs are expenses that change with the level of output, such as raw materials, electricity, and wages of temporary employees.
  3. Semi-Variable Costs: Semi-variable costs are expenses that have both fixed and variable components, such as telephone bills and utility bills.
  4. Direct Costs: Direct costs are expenses that are directly related to the production of a product, such as the cost of raw materials, labour, and packaging.
  5. Indirect Costs: Indirect costs are expenses that are not directly related to the production of a product but are necessary for the business to operate, such as rent, utilities, and administrative costs.

Factors Affecting the Cost of Production

Several factors affect the cost of production, including the following:

  1. Technology: Advances in technology can lead to lower production costs by increasing efficiency and productivity.
  2. Input Prices: The prices of raw materials and other inputs used in production can significantly impact the cost of production.
  3. Labour Costs: Labor costs, including wages and benefits, can significantly impact the cost of production.
  4. Transportation Costs: The cost of transporting raw materials and finished goods can impact the overall cost of production.
  5. Government Regulations: Regulations, such as taxes and tariffs, can impact the cost of production by increasing expenses.
  6. Exchange Rates: Fluctuations in exchange rates can impact the cost of production by affecting the prices of imported goods and raw materials.
  7. Market Competition: The level of competition in the market can impact the cost of production by affecting the price of goods and services.

Calculating the Cost of Production

The cost of production can be calculated using various methods, including the following:

  1. Total Cost: Total cost is the sum of all expenses incurred in the production of goods or services, including fixed and variable costs.
  2. Marginal Cost: Marginal cost is the additional cost incurred in producing one more unit of a product or service.
  3. Average Cost: Average cost is the total cost of production divided by the number of units produced.
  4. Opportunity Cost: Opportunity cost is the cost of using resources for one purpose instead of another.
  5. Accounting Cost: Accounting cost is the actual cost incurred in the production of goods and services.
  6. Economic Cost: Economic cost is the opportunity cost of using resources in a particular production process.
The Importance of the Cost of Production

The cost of production is crucial in determining the profitability of a business. By understanding the cost of production, businesses can set prices that cover their expenses and ensure profitability. Additionally, by analyzing the cost of production, businesses can identify areas where they can reduce costs and improve efficiency.

In addition to its impact on businesses, the cost of production also has broader implications for the economy. The cost of production affects the prices of goods and services, which can impact the purchasing power of consumers. Additionally, the cost of production can impact the competitiveness of businesses in the global market, which can affect trade and economic growth.

Conclusion

In conclusion, the cost of production is a crucial concept in

         DEFINITION OF COST OF PRODUCTION

Cost production may be defined as the sum total of all the payments to the factors of production is used in the production of goods and services.

For goods and services to be produced, all the four factors of production are land, capital, labour and entrepreneur, work together.

The various costs incurred in use of these factors of production in order produce goods and services are referred to cost of production.

Cost of production can re related to all the rewards due to factors of production, which include rent for land, wages salaries for labours, interest for capital and i for entrepreneur.

            BASIC COST CONCEPTS

(1)       Fixed cost (FC): Fixed cost also called d cost or unavoidable cost is defined as the cost or expenses that remain unchanged whatever the level of output. It simply means the cost of an enterprise which does not change with change of output. In other words, fixed cost does not change with the changing output.

Thus, no matter the quantity of commodity produced, fixed cost remains the same. Fixed cost can be represented by a graph as shown in

examples of fixed cost

Examples of fixed cost are the cost of buildings, land, motor vehicles and plant and machinery. Fixed cost is calculated by this formula:

FC – TC-VC OR

TFC = AFC x Quantity produced.

(2)       Variable Cost (VC): Variable Cost, also called direct cost, is defined as the cost of production which varies or changes directly with the level of output.

Variable cost has the tendency to rise as more of a commodity is produced and reduce as less of the commodity is produce.

 Variable cost can be represented by a graph as shown in Fig. 23.2. Examples of variable cost includes cost of fuel, raw materials, labour etc. Variable cost is calculated by this formula: VC= TC – FC

(3)        Total cost (TC): Total cost may be defined as the total sum of fixed and variable costs incurred by an enterprise in the production of a particular commodity.

Total cost, represented in Fig.23.3, is made up of two parts: total fixed cost (TFC) and total variable cost (TVC). Total cost can be calculated with this formula: TC = FC+VC or TC = ATC x Q.

(4)      Average cost (AC) or Average Total Cost (ATC): Average cost is defined as a cost per unit of output or the total cost of production of a commodity incurred by an enterprise divided by the number of units of output.

Average total cost (ATC) is divided into average fixed costs (AFC) and average variable costs (AVC).

(5)      Average variable costs (AVC): The average variable cost may be defined as the cost per unit of variable cost of output. As production increases, average variable cost may rise or fall.

The average variable cost, which can be represented graphically in Fig. 23.5, is obtained by dividing the total variable costs by the total number of output. It is calculated by this formula.

                      AVC

AVC =          TQ       =          ATC – AFC

(6)      Average fixed cost (AFC): Average fixed cost may be defined as the fixed cost of producing a unit of output. It is represented graphically in Fig. 23.6. Average fixed cost is obtained by dividing fixed cost (FC) by the number of units of output as reflected in this formula.

(7)     Marginal Cost (MC): Marginal cost also called incremental cost, may be defined as the extra cost of increasing output by one more unit. In other words, marginal cost is the cost difference in producing an additional unit of an enterprise’s output.

For example, if the cost of producing 20 tubers of yam is N50.00 and it cost N60.00 to produce 21 tubers of the same yam, the N10.00 difference in cost is known as marginal cost.

Marginal cost is represented graphically in Fig. 23.7 and is calculated using this formula:

=Changes in TC                             =     DPC

Changes in output                       DQ

            RELATIONSHIP BETWEEN TOTAL AVERAGE AND MARGINAL COSTS

The different types of costs are interrelated in a number of ways.

  • The average cost is obtained when the total cost is divided by the total output.
  •  The average fixed cost when added to the average variable cost gives the total cost.
  •  The marginal cost is derived from the difference between two consecutive total costs.
  •  Marginal cost is equal to average cost when the average cost is at its lowest point.
  • As the total cost increases, marginal cost falls up to a point at which average cost is lowest.

      RELATIONSHIP BETWEEN VC, MC, AVC, ATC AND AFC

(1)        The marginal cost curve cuts the average cost curve from below at its lowest point.

(2)      The nature of the marginal and average cost curves shows that as the level of output increases, both costs decreases up to a point.

(3)        When the average cost is falling, the marginal cost is below it while the average  cost starts rising.

(4)        The marginal cost will cross the minimum point of average total cost before rising.
(5)        The average fixed cost curve falls as output increases because the fixed cost is spread over a larger

output level. The relationship among these costs.

The law of variable proportion, also known as the law of diminishing marginal returns, is a fundamental principle in economics that describes how changes in inputs affect the output of a production process. This law states that as the quantity of one factor of production is increased while holding the other factors constant, the marginal product of that factor will eventually diminish, resulting in a decrease in the overall efficiency of production. This blog post will explore the concept of the law of variable proportion in detail, including its key assumptions, implications, and real-world examples.

Assumptions of the Law of Variable Proportion

The law of variable proportion is based on several key assumptions, which include:

  1. Fixed technology: The production technology used in a given process is assumed to remain constant over time. This means that the efficiency of production is fixed and does not change as additional inputs are added.
  2. Homogeneous inputs: The inputs used in a production process are assumed to be identical in quality and type. This means that the production process is not affected by differences in the quality or characteristics of the inputs.
  3. Variable proportion: The law assumes that one factor of production is increased while holding the other factors constant. This means that the only variable in the production process is the quantity of one input.
