Measuring the Size of Firms
When considering the size of firms, several metrics are useful for comparison and analysis
The number of employees: In 2021, Toyota had 366,000 employees whereas Hyundai had 75,000
The percentage of market share in an industry: During the 1st quarter of 2022, Samsung had 23% of the global market share for smart phones
The size of profits: in 2021, Apple made the highest level of profits for any firm, $58.4bn
Market capitalisation: The market value of a company calculated by multiplying the number of shares issued by the share price e.g. if a firm issues 5 million shares which trade at £20 each, market capitalisation is 5 x £20 = £100 m
Evaluating Small and Large Firms
Generally, small firms have fewer than 50 employees, medium firms have between 50 and 500 and large firms have more than 500 employees
Some firms choose to maintain a small-scale, focusing on niche markets, personalised services, and close customer relationships
Other firms aim to increase market share, achieve economies of scale and increase profits

Reasons Why Firms Grow
Many firms start small and grow into large companies or even multi-national corporations (Amazon started in a garage)
Two firms can combine into a single business entity to form a merger which creates rapid growth

Reasons Firms Stay Small
While many firms grow, some stay small or intentionally choose to remain small. They do this for the following reasons:
Nature of the market : Small firms are often able to offer a more personalised service and focus on building relationships with their customers
Size of market: They can provide innovative goods or services to a small section of a niche market
E.g. custom-built bicycles for competitive cyclists is a smaller market but can be very profitable
Aims of the entrepreneur: The owner's goal is not always profit maximisation but rather an acceptable quality of life or satisficing
Making just enough profit to keep the owner/shareholders happy
Lack of finance: They may be unable to access finance for expansion. They remain small to keep cost low
Less managerial problems: A smaller firm will have fewer workers and easier lines of communication with employees
Avoid rapid growth and diseconomies of scale which cause costs to rise
Avoid investigation by Government
Legislation and regulation can prevent firms from growing too large if deemed to be anti-competitive behaviour
Merger activity is monitored to prevent a single firm gaining more than significant market share
E.g. in July 2022 the CMA launched an investigation into the merger of two companies which produce foam used in bedding & cleaning products as they believed it would lead to higher prices & less choice
