Component 3: International Trade — Eduqas A-Level Business

Trade across borders splits two ways that examiners expect you to use. It splits into exports, which earn foreign currency, and imports, which spend it; and it splits into visible trade in goods and invisible trade in services, where the United Kingdom runs a surplus in areas such as finance, insurance and higher education. The balance of trade is exports minus imports, and a negative figure is a deficit. For a business the question is practical rather than macroeconomic, since selling abroad widens the market and spreads risk across economies that do not move together, while buying abroad can cut input costs. Both create exposures domestic trade does not, notably exchange rate movement, longer lead times, customs paperwork and payment risk, which is why exporters use forward contracts and letters of credit.

The economics answer is comparative advantage, Ricardo's point that trade pays even when one country is better at making everything, because what matters is the opportunity cost of producing one good rather than another. Around it sit the business reasons an examiner wants applied: a saturated or declining home market, which is market development in Ansoff's matrix, economies of scale that only a larger market makes reachable, extending a product's life cycle where the domestic version is in decline, spreading risk across territories whose economies do not move together, and sourcing materials or labour that are cheaper or simply unavailable at home. The counterweights are cultural and institutional distance of the kind Hofstede describes, plus transport cost, currency risk and the management stretch of operating far away.

Free trade means barriers are absent, so goods move on price and quality alone; protectionism means a government deliberately tilts that. A tariff is a tax on imports that raises their landed price, protecting domestic producers, raising revenue for the state and being paid in practice by importers and their customers. A quota caps the physical quantity allowed in, which lifts the price without generating any revenue. Subsidies, embargoes and administrative requirements such as standards, licensing and customs checks do the same work less visibly. For a case study firm the analysis runs through cost, then price, then volume, and then through retaliation, because protection invites it and an exporter can lose more than an importer gains. Steel safeguard measures and the tariffs traded between the United States and China are the standard examples.

A bloc is a group of countries that lower barriers to each other, and the rungs differ in ways worth knowing. A free trade area removes internal tariffs while each member keeps its own external ones, which forces rules of origin checks so goods cannot enter through the cheapest door. A customs union adds a common external tariff, so those checks disappear. A single market goes further again, letting goods, services, capital and people move freely under shared rules and standards, and a monetary union adds one currency. Members gain a larger tariff free market, scale economies and lighter paperwork, and give up the freedom to set their own external trade policy. Trade diversion is the evaluation point, where cheaper non-member suppliers are displaced by dearer members inside the wall.

Free trade allows goods and services to move across international borders without artificial tariffs, quotas, or subsidies, promoting comparative advantage, wider export markets, lower consumer prices, and competitive discipline. Protectionism shields domestic industries using tariffs (import taxes), quotas (physical quantity limits), embargoes, and domestic subsidies. Domestic subsidies lower local production costs, enabling domestic firms to undercut foreign imports, reducing import volumes indirectly without raising domestic consumer prices.

Selling an existing product into a new country is market development in Ansoff terms, and most of the risk sits in everything that is not the product. Cultural distance shows up in packaging, portion size and advertising tone, and Hofstede gives a language for it while saying nothing about how quickly a society is changing. Labelling rules, customs paperwork and duties add cost per unit, long shipping lead times tie up inventory and cash, and currency movement can erase a margin priced months earlier. Distribution is often the binding constraint, because a firm without a trusted partner loses control of shelf space and after sales service. Tesco closed its American venture in 2013 after the store format misread local shopping habits, which is what assuming a home formula travels actually costs.

Expanding into international markets (market development under Ansoff's matrix) allows firms to escape saturated domestic markets, achieve greater economies of scale, and spread commercial risk across diverse economies. However, international expansion entails significant risks: cultural and linguistic differences, foreign regulatory compliance, currency exchange volatility, complex logistics, and unfamiliar competitor rivalry. Strategic evaluation weighs potential sales growth against the managerial and financial resources required.
