New emphasis in the 2027 syllabus; types of firms, the definitions of horizontal, vertical and conglomerate mergers, and economies/diseconomies of scale are examined directly. Guidance based on specimen materials.

Firms can be classified in two ways the syllabus expects you to know.

By sector of production:

Primary-sector firms extract raw materials from nature (farming, fishing, mining, forestry).

Secondary-sector firms turn raw materials into finished or semi-finished goods (manufacturing, construction).

Tertiary-sector firms provide services (retailing, banking, transport, tourism).

By ownership:

Private-sector firms are owned by private individuals and usually aim to make a profit (sole traders, partnerships, companies).

Public-sector firms are owned and run by the government, often to provide an important service (state-owned utilities, public transport) rather than purely for profit.
