6.0     INTRODUCTION

Production refers to the process of transforming inputs (factors of production) into outputs (goods and services).

In economics, “production” refers to the process of combining various inputs (like labor, capital, and resources) to create outputs (goods or services) that have value and utility for consumers, ultimately increasing the supply in the market.

          6.1      TYPES OF PRODUCTION

• Primary Production: Extraction of raw materials (e.g., agriculture, mining).
• Secondary Production: Manufacturing and processing of goods (e.g., factories).
• Tertiary Production: Provision of services (e.g., healthcare, education).

          6.2     CONCEPTS OF PRODUCTION AND THEIR INTERRELATIONSHIPS

• Total Product (TP): The total quantity of output produced by a firm.
• Average Product (AP): The output produced per unit of a variable input, calculated as AP = TP/Q​ where Q is the quantity of the variable input.
• Marginal Product (MP): The additional output produced by adding one more unit of a variable input, calculated as MP = ΔTP/ΔQ.

LAW OF VARIABLE PROPORTIONS: As more units of a variable input are added to fixed inputs, the TP initially increases at an increasing rate, then at a decreasing rate, and eventually may decline.

DIVISION OF LABOUR: The process of breaking down production into smaller tasks, allowing workers to specialize in specific tasks.

SPECIALIZATION: Increases efficiency and productivity as workers become skilled in their specific tasks, leading to faster production and higher quality.

          6.3     ECONOMIES OF SCALE

Economies of scale are the cost advantages that enterprises obtain due to their scale of operation and are typically measured by the amount of output produced per unit of cost. A decrease in cost per unit of output enables an increase in scale that is, increased production with lowered cost.

TYPES OF ECONOMIES OF SCALE

• Internal Economies of Scale: This is the cost advantages that a firm experience as it increases its production. Examples include bulk purchasing, improved technology, and managerial specialization.
• External Economies of Scale: Refers to the cost benefits that accrue to all firms in an industry as the industry grows. Examples include improved infrastructure and skilled labor availability.

6.4     PRODUCTION FUNCTIONS AND RETURNS TO SCALE

PRODUCTION FUNCTION: A mathematical representation of the relationship between inputs and outputs.

RETURNS TO SCALE: Refers to how output changes as all inputs are increased proportionately:

• Increasing Returns to Scale: Output increases by a greater proportion than the increase in inputs.
• Constant Returns to Scale: Output increases in the same proportion as inputs.
• Decreasing Returns to Scale: Output increases by a lesser proportion than the increase in inputs.

6.5     PRODUCERS’ EQUILIBRIUM: ISOQUANT-ISOCOST AND MARGINAL ANALYSIS

PRODUCERS’ EQUILIBRIUM: The point where a producer maximizes output for a given cost.

ISOQUANT: A curve that represents all combinations of inputs that yield the same level of output.

ISOCOST: A line that represents all combinations of inputs that have the same total cost.

MARGINAL ANALYSIS: Involves comparing the additional benefits of an input to its additional costs to determine the optimal level of input usage.

          6.6     FACTORS AFFECTING PRODUCTIVITY

• Technology: Advances can lead to more efficient production processes.
• Labor Skills: Higher skill levels can improve productivity.
• Capital: Availability of machinery and equipment can enhance production capacity.
• Management: Effective management practices can optimize resource use.
• Economic Environment: Factors like government policies, market conditions, and competition can influence productivity.
