Chapter 8 Flashcards
What are Inputs / Factors of production
- Labour
- Land
- Capital
What is the short run usually constrained by?
One factor of production
As price for a item decreases what will happen to demand?
Quantity demand decreases
As price for an item increases what will happen to demand?
Quantity demand increases
What does the quantity axis show and what does this mean?
The quantity axis shows effective demand = what we’re willing and able to demand
List factors which can effect demand
- Complementary goods – e.g. if buying butter if bread price decreases then demand for butter will increase.
- Substitute goods – same as competitors e.g. if price for butter substitutes increases then butter demand would increase
- Consumer income – normal goods rise in demand as well as luxury goods. If income decreases then demand for inferior goods will increase (e.g. own brand goods)
- Tastes
- Advertising
What is supernormal profit?
also called excess profit, supernormal profit or pure profit, is “profit of a firm over and above what provides its owners with a normal return to capital.
Profit in excess of
• Measured costs
• Opportunity costs – costs associated with the next best use of the unborrowed capital tied up in the business and the use of the owner’s time
What is marginal cost
The change in the total cost that arises when the quantity produced is incremented by one unit; that is, it is the cost of producing one more unit of a good.
What is marginal revenue
Marginal revenue (MR) is the increase in revenue that results from the sale of one additional unit of output.
What is profit maximisation?
profit maximization is the short run or long run process by which a firm may determine the price, input and output levels that lead to the highest profit.
What are fixed costs?
Are costs which do not vary with the level of output e.g. rent / advertising
What is a variable cost
a variable cost is dependent on the production output level of goods and services.
When do variable costs rise and fall?
cost rises as the production output level rises and decreases as the production output level decreases.
What are economies of scale?
Economies of scale are cost advantages reaped by companies when production becomes efficient.
What is perfect competition?
A market structure in which neither buyers nor sellers believe that they can influence the market price by any actions of their own
what would the demand line in a perfect competition market look like
horizontal - can sell as much as it wants at the prevailing market price
In perfect competition what do both buyers and sellers regard themselves as?
pricetakers
what tends to be given as a good e.g. of perfect competition?
Agriculture
No individual farmer can influence market price by selling more or less of any commodity since their impact on overall market supply is negligible.
In addition no individual buyer is in a strong enough position to influence price by offering to buy more or less of a product.
Is a homogeneous product
list features of perfectly competitive markets
o Homogenous product
o Large number of independent firms, each small relative to industry size
o No barriers to entry or exit of industry. This guarantees that if a group of firms decide to restrict supply to force prices higher then the extra profit will attract new firms and force prices down again.
o Perfect information - appropriate info for consumers to appreciate homogeneity
What is supply elasticity?
the % change in quantity supplied in response to a given change in % price.
