3.5.2 - The Objectives of Firms Flashcards
What does traditional theory assume about entrepreneurs who run firms?
To maximise profit by producing the optimal output.
What is the equation for total profit?
Total revenue - Total Cost
What does profit maximisation look like in an equation?
The point at which TR - TC is maximised.
What equation can find when profit has been maximised?
When MR = MC.
What does MR = MC actually mean in practice?
A firm’s profits are greatest when the addition to sales revenue received from the last unit sold (marginal revenue) is equal to the total cost incurred from making the last unit (marginal cost).
Give and explain an example of MR = MC in the real world?
If the ruling market price is 50p per kilo of flour, at any output, the average revenue is 50p per kilo, meaning marginal revenue is also 50p.
Suppose a miller markets 400 kilos of flour, the cost of producing and marketing the 400th kilo is 48p. There is 2p of profit per kilo left. If the 402nd kilo is 52p, there is 2p of profits lost. If the 401st kilo is 50p to market and produce, the marginal cost is equal to the marginal revenue of 50p, meaning profits have been maximised.
What happens to profits when MR > MC?
Profits rise as output increases.
What happens to profits when MR < MC?
Profits rise as output decreases.
What should a firm do when MC < MR?
Increase the output.
What should a firm do when MC < MR?
Reduce the output.
What should a firm do when MC = MR?
Nothing, profit has been maximised at their current size.
How does a firm maximise profits in any market structure?
Ensure that MC = MR.
What is the divorce of ownership from control?
The owners and those who control the firm are different groups with different objectives.
Do small firms experience a divorce of ownership from control?
No, the entrepreneur tends to be the owner.
Do large firms experience a divorce of ownership from control, and if so, why?
Yes.
Medium and large sized companies are often owned by thousands of shareholders, with a select few owning the majority.
Despite the firm being owned by shareholders, they do not decide what happens with the company as executive directors decide what to do.
