Most firms have the rational business objective of profit maximisation
Profit maximisation
Profits benefit shareholders as they receive dividends & also increase the underlying share price
An increase in the underlying share price increases the wealth of the shareholder
Profit maximisation rule
When marginal cost (MC) = marginal revenue
Profit maximisation rule
When marginal cost (MC) = marginal revenue (MR) then no additional profit can be extracted by producing another unit of output
When MC < MR additional profit can still be extracted by producing an additional unit of output
When MC > MR the firm has gone beyond the profit maximisation level of output and is making a marginal loss on each unit produced beyond the point where MC = MR
In reality, firms may find it difficult to produce at the profit maximisation level of output as they may not know where this level is
In the short term firms may not adjust their prices if the marginal cost changes as regular price changes would be disruptive to customers
In the long-term firms will seek to adjust prices to the profit maximisation level of output
Firms may be forced to change prices by the Competition Commission
The profit maximisation level of output often results in high prices for consumers
Revenue maximisation
Some firms have the business objective of revenue maximisation
Principal-agent problem
This often occurs due to the principal-agent problem where sales managers receive commission on sales as part of their wages and this incentivises them to maximise sales rather than profit maximisation for shareholders
Firms will also maximise revenue in order to increase output and benefit from economies of scale
In the short-term firms may use revenue maximisation to eliminate the competition as the price is lower than when focussing on profit maximisation
Revenue maximisation rule
To achieve revenue maximisation firms produce up to the level of output where MR = 0
When MR > 0, producing another unit of output will increase total revenue
The revenue maximisation level of output results in a lower supernormal profit than the profit maximisation level of output
Sales maximisation
Some firms have the business objective of sales maximisation
The sales maximisation level of output occurs at the level where AC = AR (normal profit/breakeven)
In the short-term firms may use sales maximisation to clear stock during a sale, selling remaining stock without making a loss per unit
Satisficing
Some firms have the business objective of satisficing, where managers settle for a level of output somewhere between profit and sales maximisation in order to increase their wages and reduce potential conflict with shareholders
Rationally, managers know shareholders want to profit maximise, but rationally managers want to maximise sales or revenue so as to increase their wages
Firm's motives
Determined by who controls it
People who could have control
Owners or shareholders
Directors and managers
Workers (through a trade union)
The state (through regulation, taxes/subsidies and direct control)
Consumers (through their consumer sovereignty)
Pressure groups
Profit maximisation
(in neo-classical economics) The goal of firms is to profit maximise in the short run, in order to maximise owners' returns
Firms profit maximise
To generate funds for investment and to help them survive a slowdown during a recession
Firms likely to profit maximise
Apple
Pharmaceutical companies
To short run profit maximise
Firms produce where MC=MR
Profit maximisation
Firms produce at P1Q1: the output is determined by where MC=MR and the price at this output is determined by the AR curve
Revenue maximisation
Managers are most interested in their level of revenue since this is what their salary depended on
Managers aim to revenue maximise
As long as they provide some profit for the owners
Firms following revenue maximisation
Amazon
To revenue maximise
Firms produce where MR=0
Revenue maximisation vs profit maximisation
Prices would be lower than when they are profit maximising since they are producing more
Sales maximisation
Managers aim to maximise the growth of their company above any other objective
Reasons for sales maximisation
Salary may be linked to the size of the company
Easier for people to judge the level of growth achieved rather than the level of profit
Size is often linked to security
Growth will increase market share and market power
Firms following sales maximisation
Netflix
Spotify
To sales maximise
Firms produce where AC=AR at P2Q2
The problem with both sales maximisation and revenue maximisation is that it necessitates a fall in price, which other firms may copy and so there may be no or little increase in revenue or sales
