Production & Factors

NODE 01

Production

• Transforming inputs into goods/services.
• Satisfies human wants.
• Goods = Tangible (cars, food).
• Services = Intangible activities (education).

NODE 02

Factors of Production

LND

LAB

CAP

ENT

• Land: Natural resources (Rent).
• Labour: Human physical/mental effort (Wages).
• Capital: Produced assets (Interest).
• Entrepreneurship: Organization & Risk (Profit).

NODE 03

Fixed & Working Capital

• Fixed: Used repeatedly over time.
• E.g., Machinery, buildings, vehicles.
• Working: Used up in the production cycle.
• E.g., Raw materials, fuel, daily cash.

NODE 04

Physical & Human Capital

VS

• Physical: Machines, tools, equipment.
• Human: Knowledge, skills, health embodied in people.
• Education/Health → Higher Productivity.
• Direct link to Human Development.

NODE 05

Productivity

↑

• Efficiency of input conversion.
• Output ÷ Labour Input = Labour Productivity.
• Higher output from same resources.
• Driven by tech, skills, and management.

NODE 06

Division of Labour

• Breaking production into assigned tasks.
• Pros: Skill gain, time saving, scale.
• Cons: Repetitive, specialized vulnerability.
• Foundation of factory assembly lines.

NODE 07

Specialisation

• Concentrating on particular activities.
• Individual: e.g., Doctor.
• Firm: Specialized product focus.
• Regional/International: Comparative advantage.

NODE 08

Economic Sectors

TERTIARY

SECONDARY

PRIMARY

• Primary: Dependent on natural resources (Agri, Mining).
• Secondary: Processing/Manufacturing (Factories).
• Tertiary: Services (Transport, Banking, Trade).

NODE 09

Quaternary Sector

🧠

• Knowledge-intensive activities.
• IT, R&D, Data Analysis, Consulting.
• Advanced scientific services.
• Core to the modern digital economy.

NODE 10

Sectoral Transformation

→

→

• Relative importance shifts as economies develop.
• Agriculture-heavy → Industrialization → Services.
• Culminates in Knowledge/Digital economy.
• Structural transformation process.

NODE 11

Production Function

f ( L, K ) ➔ Q

• Relationship between inputs and output.
• Q = f(L, K, land, tech, entrepreneurship).
• How much output from given inputs?
• Depends heavily on prevailing technology.

NODE 12

Short vs Long Run

F

V

SHORT

V

V

LONG

• Short Run: At least one factor is fixed (e.g. building).
• Only variable inputs (labour, raw materials) change.
• Long Run: All factors can vary.
• Can expand capacity or build new factories.

NODE 13

TP, AP, MP

• Total Product (TP): Total amount produced.
• Average Product (AP): TP ÷ Variable Input.
• Marginal Product (MP): Additional output from +1 input.
• MP = Change in TP ÷ Change in Input.

NODE 14

Law of Variable Proportions

• Adding variable inputs to fixed factors.
• Output initially rises rapidly.
• Then rises slowly (Diminishing Marginal Returns).
• Eventually, additional units yield negative returns.

NODE 15

Returns to Scale

• Increasing all inputs proportionately (Long Run).
• Increasing: Output grows > proportionately.
• Constant: Output grows = proportionately.
• Decreasing: Output grows < proportionately.

NODE 16

Technology

• Determines how inputs are combined.
• Increases productivity & lowers costs.
• Creates new industries / destroys old ones.
• Tech → Productivity → Economic Transformation.

NODE 17

Infrastructure

• Production needs an enabling environment.
• Roads, railways, ports, power grids.
• Digital and communication networks.
• Reduces transaction and transport costs.

NODE 18

Scale of Production

vs

• Small-scale: Limited productive capacity.
• Large-scale benefits: Machinery, specialization.
• Bulk purchasing & large markets.
• Leads to Economies of Scale.

NODE 19

Economic Activities

PRD

EXC

CON

DIS

• Production: Creating goods/services.
• Consumption: Using them to satisfy wants.
• Exchange: Trading goods/services.
• Distribution: Sharing income/output among participants.

NODE 20

Production → Income

→

• Production generates income for factor owners.
• Land → Rent | Labour → Wages.
• Capital → Interest | Entrep → Profit.
• Feeds the circular flow of the economy.

NODE 21

The Master Chain

• Natural Resources → Factors of Production.
• Land + Labor + Capital + Entrep.
• + Tech/Org → Production (Goods/Services).
• → Income → Consump/Invest → Growth.
