Production and Costs Summary

Organization of Production

Production involves firms combining inputs (land, labour, capital) to create outputs (goods and services) to satisfy consumers’ needs.

Value Added

Value added is the difference between the market price and the cost of resources used, calculated as: Value\,added = profit + wages

Industrial Sectors

  • Primary Sector: Extraction of natural resources.

  • Secondary Sector: Construction and manufacturing.

  • Tertiary Sector: Services (personal and business).

Aims of Production

Private sector firms maximize profit, which is the surplus of revenue over costs. Other organizations include:

  • Charities: Rely on donations.

  • Not-for-profit: Reinvest surplus or lower prices.

  • Public sector: Provide public services.

Productivity

Productivity measures output from a given amount of input. Businesses aim to maximize output with minimal resources.

Labour Productivity

Measured by average output or revenue per employee per period.

Improving Productivity Strategies

  • Training employees.

  • Performance-related pay.

  • Increasing job satisfaction.

  • New technologies.

  • Efficient production processes.

  • Division of labour.

  • Factor substitution.

Division of Labour

Specialization in specific tasks. Advantages include efficient use of skills and increased output. Disadvantages include boredom and lack of pride in work.

Capital vs. Labour Intensity

The relative demand depends on output demand, relative costs, and productivity.

Factor Substitution

Replacing labour with capital due to increased capital productivity or lower capital costs. However, personalized services and affordability can limit substitution.

Costs of Production

  • Fixed Costs: Do not vary with output (e.g., rent).

  • Variable Costs: Vary directly with output (e.g., materials).

Total\,Variable\,Cost = Variable\,Cost\,per\,unit \times Number\,of\,units

Total\,Cost = Total\,Fixed\,Cost + Total\,Variable\,Cost

Average Costs

Average costs tend to fall as output rises but may increase after a certain point.

Profit, Loss, Break-Even

Profit = Total\,Revenue - Total\,Cost

Break-even: Total\,Revenue = Total\,Cost

Break-Even Point

Making it easier to break even involves increasing price (average revenue) or reducing costs.
