Business Objectives Flashcards
What objective are firms assumed to be
Firms are assumed to be profit maximisers, but sometimes they may opt to satisfy different objectives such as revenue maximisation or sales maximisation.
When does profit maximisation occur
Profit maximisation occurs at the output level where supernormal profits are at their greatest (or losses are at their lowest). This occurs where marginal cost is equal to marginal revenue (MC =MR), but while this is a necessary condition, it is not sufficient. Marginal cost must also be rising.
Define profit maximisation
Occurs where MC = MR. it is where the firm maximises profits or minimise losses.
How is profit represented on a diagram
When MC is below MR - the area beneath the MR is profit.
When MC = MR what happens
No more profit can be made either by increasing or decreasing output. The marginal profit is zero.
How can we evaluate profit maximisation
When evaluating profit maximisation, consider whether the local coffee shop knows the marginal costs of a cup of coffee. Furthermore, what would it do if it knew that level of output? Would it stop selling because the next item would result in a fall in total profit? Some firms, then, look to other objectives.
When does revenue maximisation occur
It occurs when a firm seeks to make as much revenue as possible. Firms are willing to sell products until the last unit sold adds nothing to total revenue, knowing that the next unit sold will reduce revenue: that is, they sell until the marginal revenue is zero.
Define revenue maximisation
When a firm maximises total revenue. This occurs where marginal revenue = 0
When the MR curve touches the x axis (equals 0) what happens to the TR curve
It is n shape and at this point is the turning point.
On any questions on revenue maximisation draw a diagram showing the parabola-shaped TR curve with its peak lining up with where the MR crosses the horizontal axis. Mark on MR=0. It shows that as the firm expands output, the marginal revenue declines. While marginal revenue is positive, it continues to add to total revenue; it is only when it passes zero and becomes negative that total revenue starts to decline.
What’s sales maximisation
Sales maximisation occurs when a firm attempts to sell as much as it can without making a loss. That is, it sells as much as it can subject to the constraint of making normal profits. This occurs where average cost equals average revenue .
Where AC = AR this is…
Sales maximisation.
Tell me how not to confuse sales maximisation with something else
Do not confuse sales maximisation, AR = AC, with sales revenue maximisation, MR =0 (which Is referred to in this guide as revenue maximisation).
Remember that sales maximisation is the highest level of sales given that the firm must makes normal profit. It is also called output maximisation.
Why may firms embark on revenue or sales maximisation
In an effort to gain market share or drive a rival out of the industry. Prices are lower than under perfect competition and output is higher.
Define allocative efficiency
Producing at a point where the price of a good is equal to the marginal cost of production
Why may government seek to ensure that firms operate at the allocatively efficient point (other motive for firms)
This is where price equals marginal cost. In other words, the price paid for a good is equal to the cost of the factors of production used to manufacture the last unit.
