Production, Costs, Revenue, and Profit

Production

Production

The process of converting inputs (factors of production) into outputs (goods and services).

Factors of Production

Resources including land, labor, capital, and entrepreneurship used in the production process.

Land

Natural resources used in production (e.g., minerals, forests, water).

Labor

Human effort, both physical and mental, is used in production.

Capital

Man-made resources (e.g., machinery, buildings) used in production.

Entrepreneurship

The initiative to combine the other production factors and bear the business risks

Types of Production

Primary, Secondary, and Tertiary categorize activities based on the nature of goods and services produced.

Primary Production

Extraction of natural resources (e.g., farming, fishing, mining).

Secondary Production

Manufacturing and construction (e.g., car production, building houses).

Tertiary Production

Services (e.g., education, healthcare, retail).

Production Processes

Job, Batch, and Flow production methods define how goods are manufactured.

Job Production

Producing unique items tailored to customer requirements.

Batch Production

Producing a limited number of identical items in groups or batches.

Flow Production

Continuous production of identical items on an assembly line.

Productivity

Measure of efficiency, output per unit of input, influenced by technology, skills, management, and economies of scale.

productivity

Factors affecting _______:

• Technology advancements

• Worker skills and training

• Management practices

• Economies of scale

Costs

Fixed, Variable, Total, Average Fixed, Average Variable, Average Total, and Marginal Costs are key concepts in ____ analysis.

Fixed Costs (FC)

Costs that do not vary with output (e.g., rent, salaries).

Variable Costs (VC)

Costs that vary directly with output (e.g., raw materials)

Total Costs (TC)

The sum of fixed and variable costs: TC = FC + VC

Average Fixed Costs (AFC)

Fixed cost per unit of output:  AFC = FC/Q

Average Variable Costs (AVC)

Variable cost per unit of output: AVC = VC/Q

Average Total Costs (ATC)

Total cost per unit of output: ATC = TC/Q

Marginal Costs (MC)

The additional cost of producing one more unit of output: MC = ΔTC/ΔQ

Short-Run Costs

The period in which at least one factor of production is fixed.

Long-Run Costs

The period in which all factors of production can be varied.

Firms experience economies and diseconomies of scale.

Total Revenue (TR)

Total income from sales: TR = P × Q  (Price x Quantity)

Average Revenue (AR)

Revenue per unit sold: AR = TR/Q

Marginal Revenue (MR)

Additional revenue from selling one more unit: MR = ΔTR/ΔQ

Perfect Competition

Firms are price takers, AR = MR = Price.

Example: Agricultural products like wheat.

Monopoly

Single seller, AR and MR diverge, MR < AR.

Example: A local utility company.

Oligopoly

Few firms, kinked demand curve, interdependent pricing.

Example: Automobile industry

Monopolistic Competition

Many firms, product differentiation, and some pricing power.

Example: Restaurants

1. Normal Profit

2. Supernormal (Economic) Profit

2 types of profit

Normal Profit

Minimum profit necessary to keep a firm in business.Occurs when TR = TC.

Supernormal (Economic) Profit

Profit over and above normal profit.

Occurs when TR > TC

Profit Maximization

Objective: Firms aim to maximize the difference between total revenue and total costs.

Marginal Cost (MC) = Marginal Revenue (MR)

Condition for Profit Maximization

Accounting Profit

Total revenue minus explicit costs.

Example: TR is £1,000, explicit costs are £600, accounting profit is £400

Economic Profit

Total revenue minus both explicit and implicit costs (opportunity costs).

Example: TR is £1,000, explicit costs are £600, implicit costs are £200, economic profit is £200

Break-Even Analysis

Determines the level of output where total revenue equals total costs, indicating no profit or loss.

Break-Even Point

Level of output where total revenue equals total costs (no profit or loss)

Break-Even Formula

Break-even output = Fixed Costs / (Price - Variable Cost per unit)

what formula?

Impact of Changes in Costs and Revenue

Cost Increases, Revenue Increases, Efficiency Improvements

Cost Increases

Higher fixed or variable costs reduce profit.

Example: Increase in raw material prices

Revenue Increases

Higher prices or greater sales volume increase profit.

Example: Launching a successful advertising campaign

Efficiency Improvements

Lower costs, and increase productivity, leading to higher profit margins.

Example: Implementing a new production technology

Cost Curves

What type of curve?

MC Curve

ATC and AVC Curves

AFC Curve

MC Curve

Typically U-shaped due to initially decreasing and then increasing marginal costs

ATC and AVC Curves

U-shaped, with AVC lying below ATC.

AFC Curve

Downward sloping as fixed costs are spread over more units

Revenue Curves

what type of curve?

TR Curve

AR and MR Curves

TR Curve

Upward sloping, but slope varies by market structure

AR and MR Curves

In perfect competition, ______________ at the market price.

AR, MR

In monopoly and imperfect competition, ___ is downward sloping, and ___ lies below AR

profit-maximizing

The intersection of MR and MC curves determines ____________ output

profit

The difference between TR and TC at this output indicates the level of ____
