Private sector vs public sector
· Private sector = businesses owned by individuals or organizations and mainly aiming to make profit.
· Public sector = organizations owned and controlled by the government/state and mainly aiming to provide public services or meet social needs.
· In exams, link the distinction to ownership, control, objectives, source of finance, and accountability.
· Private sector firms are usually judged by profit, growth, and return to owners/shareholders.
· Public sector organizations are usually judged by service quality, accessibility, public value, and efficient use of taxpayer money.
· A business can move between sectors through privatization or nationalization.

This figure gives a simple visual overview of major business structures. It is useful for seeing how sole proprietorships, partnerships, and corporations fit into the wider set of legal business forms. Source
Sole traders
· Sole trader = a business owned by one person.
· Main strengths: easy to set up, quick decision-making, full control, keeps all profit after tax.
· Main weaknesses: unlimited liability, limited access to finance, heavy workload, and the business may depend too much on one owner.
· Best suited to small-scale businesses, local services, and businesses where owner control is important.
· Exam tip: when evaluating, balance simplicity and control against risk and limited growth potential.
Partnerships
· Partnership = a business owned by two or more people who share responsibility, profit, and usually decision-making.
· Main strengths: more capital than a sole trader, shared workload, broader skills/expertise, and easier business continuity.
· Main weaknesses: possible disagreements, shared profit, and in many cases unlimited liability for partners.
· A clear partnership agreement is important because it sets out roles, profit sharing, and how disputes are resolved.
· Exam tip: a partnership can be strong when businesses need combined expertise, but weak if there is conflict between partners.
Privately held companies
· Privately held company = a company owned by private individuals/shareholders, usually with shares not sold to the general public.
· Main strengths: limited liability, greater ability to raise finance than sole traders/partnerships, and the business has a separate legal identity from its owners.
· Main weaknesses: more legal formalities, higher set-up costs, and less direct control for each owner compared with a sole trader.
· Shares are usually held by founders, family members, or a small group of investors.
· Useful for firms wanting growth but not wanting to lose control by selling shares on a public stock exchange.
· Exam tip: emphasize limited liability, continuity, and improved finance access versus less flexibility and greater regulation.
Publicly held companies
· Publicly held company = a company whose shares can be bought and sold by the public, usually on a stock exchange.
· Main strengths: very strong ability to raise large amounts of capital, easier expansion, and shareholders have limited liability.
· Main weaknesses: greater legal regulation, more public scrutiny, pressure for short-term results, and risk of loss of control by original owners.
· Ownership and control are often separated: shareholders own the company, while directors/managers run it.
· Public companies often have more potential for rapid growth, but also face more pressure from investors, media, and regulators.
· Exam tip: compare public companies with private companies by focusing on access to finance, control, and accountability.
For-profit social enterprises
· Social enterprise = an organization that uses business activity to achieve a social/environmental purpose.
· It still earns revenue, but profit is not the only objective.
· In exams, always show the double aim: financial sustainability + social impact.
For-profit social enterprises: private sector companies
· These are privately owned businesses operating in the private sector but with a clear social mission.
· They aim to make profit and create positive social/environmental outcomes.
· Strength: can be innovative, entrepreneurial, and responsive to market demand.
· Limitation: there may be tension between profit goals and social objectives.
For-profit social enterprises: public sector companies
· These are government-owned or government-supported organizations using commercial activity to achieve a social purpose.
· They often aim to improve public welfare while covering some costs through trading income.
· Strength: can support services with strong social value.
· Limitation: may face bureaucracy, political pressure, or lower commercial flexibility.
Cooperatives
· Cooperative (co-op) = a business owned and run by its members for their mutual benefit.
· Members may be customers, workers, or producers.
· Key feature: democratic control — often one member, one vote.
· Main strengths: strong member involvement, shared purpose, and profits/surplus are usually distributed according to member participation rather than size of investment.
· Main weaknesses: slower decision-making, possible difficulties raising large capital, and compromise may be needed between members’ interests.
· Exam tip: distinguish co-ops from investor-owned businesses by focusing on member ownership, democratic control, and mutual benefit.

This visual is useful for showing that social enterprises use different ways to create impact while still trading. It reinforces the idea that a social enterprise combines commercial activity with a social purpose rather than focusing only on profit. Source
Non-profit social enterprises: NGOs
· NGO (non-governmental organization) = an independent organization that is not part of government and is usually created to achieve social, environmental, or humanitarian aims.
· NGOs are a form of non-profit social enterprise in this topic.
· Main aim: create social value, not distribute profit to owners.
· Finance may come from donations, grants, fundraising, and sometimes trading activities.
· Main strengths: strong mission focus, public trust, and ability to address social problems.
· Main weaknesses: reliance on external funding, resource constraints, and pressure to prove impact/accountability.
· Exam tip: do not confuse an NGO with a normal private business — the key difference is purpose and non-profit distribution.
