Chapter 8 Flashcards
Define a firm
A firm is an organization that combines all factors of production to produce a good or service that satisfies consumer needs and wants
Factors that influence size of a business
- Nature of market
- Industry and sector
- Capital investment
- Technology
Define short-run production
Increasing level of output by increasing the variable resources, but there must be at least one fixed F.O.P.
Usually, labour is the variable resource since it’s easy to hire more people.
But, capital is a fixed factor of production.
Define long-run production
Increasing level of output by varying ALL quantities of factors of production; including both fixed and variable resources.
A firm is more flexible on the long-run, and can afford buying more machinery.
Define production function
Relationship between input and output; it shows how the quantity of F.O.P is reflected back on level of output.
Explain law of diminishing marginal returns
A law that states that if a firm constantly increases its input (mainly labour), there will be a point where the firm starts to gain decreasing levels of output. This might be due to overcrowding in work field.
This highlights importance of balance, excessive resources might lead to inefficiencies. (Unused labour)
Define total costs
All costs incurred to produce a given level of output.
Fixed costs + variable costs.
Define fixed costs
Costs that do not vary with level of output; no matter if the business is making profits or losses, they must be paid regardless.
Example: Rent.
**Opportunity cost is considered as a fixed cost.
Define variable costs
Costs that vary with level of output; the higher the production levels, the higher the costs incurred.
Examples: Raw materials
Define total revenue
Price x Quantity sold.
**Also, average revenue=price
Define average revenue
Revenue gained per unit, which is equal to price.
**Marginal revenue falls more rapidly than average revenue.
Define breakeven point
Point where no profits or losses are made; costs are equal to revenues.
What are the short-run production costs?
- Average cost: Cost per unit
- Marginal Cost: Additional cost per additional unit produced[=1
**Marginal cost is related to marginal principle; where we see if it’s worth the cost to produce an addition unit - Marginal revenue: Additional revenue gained per additional unit sold.
What are the long-run production costs?
- Increasing returns to scale: A percentage increase in input will lead to an even higher increase in the percentage of output.
- Decreasing returns to scale: A percentage increase in input will lead to a smaller percentage increase in output. (Law of diminishing marginal returns)
- Constant returns to scale: Percentage increase in input is equal to the percentage increase in output.
Define normal profits
The return needed for a firm to be able to survive in the market on the long-run.
It is mostly earned in perfect competition, where there is a small gap between AC and AR because they’re perfectly elastic and have no influence over prices.
Define supernormal profits
Profits gained above normal profits; there’s a huge gap between AC and AR.
It is mostly earned in monopoly markets as they can set very high prices as price maker and inelastic
Define subnormal profits
Profits earned below normal profits, where business is making losses. This can be in a perfect competition market where there are high taxes, so they carry the burden.
Define accounting profits
Calculation of profits excluding opportunity cost from the fixed costs as it’s not an explicit value.
Shut-down price in the short run
On the short run, the business focuses on covering their variable costs. If the price paid per product does not cover the marginal cost, the business will shut down temporarily. They will stop selling only.
Price = MC/AC
**Can postpone fixed costs later
example: on the short run, a pizzeria must cover the cost of their ingredients to be able to operate.
Shut-down price in the long run
On the long run, the business must cover all costs, both fixed and variable. If the price does not cover it, then the business will exit the market permanently.
They will stop selling their products, and will sell their business.
example: on the long run, pizzeria must cover both cost of ingredients AND rent and oven installments.
Define economies of scale
An increase in scale of production will lead to a decrease in average costs paid per unit.
Define external economies of scale
Due to expansion of WHOLE industry
Define internal economies of scale
Due to expansion of firm
Examples of internal economies of scale
- Purchasing economies of scale: Purchasing in bulk will allow the firm to get discounts
- Technical E.O.S: The firm is capable of affording specialists and high-tech machinery due to high budget.
- Marketing E.O.S: The firm can split the cost of advertisement onto multiple products. There will be lower costs per unit.
- Financial E.O.S: Banks will be more willing to offer lower interest rates when taking big loans.
- Diversification
