What are external economies of scale?

Cost advantages that arise from factors outside the business itself, typically resulting from the growth of the industry or geographic clustering of firms.

Where do external economies of scale originate from?

They originate from factors external to the individual business, such as industry growth or the concentration of businesses in a particular geographic area.

How does geographic clustering of firms lead to external economies of scale?

When businesses in the same industry locate near each other, they can share infrastructure, access a specialised labour pool, benefit from supplier networks, and gain from knowledge spillovers, reducing costs for all firms in the cluster.
