○ Risk bearing economies
■ Large firms with a high output can sell into different markets(even overseas); They are
able to produce a variety of products. This means that risks are spread over a wider
range of products or markets, even if a market of product is not successful, they have
other products and markets to continue business in. this costs are less
● External economies of scale
○ They occur when firms benefit from the entire industry being large
○ Access to skilled workers
■ Large firms can recruit workers trained by other firms. For example, when a new training
institution for pilots and airline staff opens, all airline firms can enjoy economies of scale
of having access to skilled workers who are more efficient and productive
○ Ancillary firms
■ They are firms that supply and provide materials/services to larger firms. When ancillary
firms such as a marketing firm are located close to a company, the company can cut
costs by using their services more cheaply than other firms.
○ Joint marketing benefits
■ When firms in the same industry locate close to each other, they may share an
enhanced reputation and customer base
○ Shared infrastructure
■ Development in the infrastructure of an industry or the economy can benefit from large
firms. For example better and more roads can cut on transportation costs for the firms.
● Diseconomies of scale
○ They occur when a firm grows too large and average costs start to rise
○ Management diseconomies
■ Large firms have a wide internal organisation with lots of managers and employees. This
makes communication difficult and decision making very slow. This leads to inefficient
running of firms and increased costs
○ Too much output
■ May require large supply of raw materials, power etc. which can lead to shortage and
halt production, increasing costs
○ Demotivation and less cooperation
■ Workers operating machine may feel bored this become demotivated, many workers
may leave or go on strikes, halting production
○ Agglomeration diseconomies
■ When firms merge/acquire too many different firms producing different products, the
owners can't coordinate and organise all activities, leading to higher costs.
○ The products become too standardised and less a variety in the market
■ This will reduce sales and profits and increase average costs
● A firm that doubles its inputs (resources) and is able to more than double its output as a result
experiences increasing returns to scale
● A firm that doubles its inputs but fails to double its output as a result experiences diminishing return to
scale
