International Competitiveness (Balance of Payments, Exchange rates and International Competitiveness)

Country A's unit labour cost = total labour cost ÷ output = £90,000,000 ÷ 300,000 = £300 (1).

Relative to Country B (B = 100): (300 ÷ 250) × 100 = 120 (1). This means Country A's unit labour cost is 20% higher than Country B's, so Country A is less price-competitive.

Non-price competitiveness is the ability of a country's firms to compete in global markets through factors other than price (1). Instead of undercutting rivals, firms win sales through the quality, design, branding, reliability, technology and after-sales service of their products (1).

For example, a German car maker may sell successfully abroad despite high prices because buyers value its engineering quality and brand reputation (1). Because customers choose the product for these qualities, demand becomes less price-elastic, so the firm can charge a premium and still export — which is why non-price competitiveness is especially important for high-wage economies that cannot win a price war against low-cost producers (1).

International competitiveness is the ability of a country's firms to compete in global markets, and it is shaped by several determinants. Two important ones are labour productivity and the exchange rate.

Determinant 1 — labour productivity. Labour productivity is output per worker. If productivity rises faster than wages, the country's unit labour costs fall (unit labour cost = wage ÷ productivity). Lower unit costs let firms sell exports more cheaply while remaining profitable, so they become more price-competitive and can win more sales abroad. This is the most sustainable driver of competitiveness because it is structural and lasting.

Determinant 2 — the exchange rate. A fall (depreciation) in the exchange rate makes a country's exports cheaper in foreign currency and imports dearer. This raises price competitiveness quickly, boosting export demand. Unlike a productivity gain, however, this works through price alone and can be reversed if the currency later appreciates.

Both determinants therefore affect competitiveness mainly through price, but productivity does so durably while the exchange rate does so temporarily.

Supply-side policies aim to raise the economy's productivity and efficiency, cutting unit costs and improving product quality — both of which raise international competitiveness. Two examples follow.

Policy 1 — spending on education and training. Government spending on schools, universities, apprenticeships and skills raises workers' human capital. Better-skilled workers are more productive, so output per worker rises. If productivity rises faster than wages, unit labour costs fall, making exports more price-competitive. Better skills also raise the quality and design of goods, improving non-price competitiveness. So education works on both fronts — though it takes years to feed through.

Policy 2 — R&D incentives (grants and tax breaks for research). Support for research and innovation speeds up technological advance and new product development. This raises productivity (lowering unit costs) and improves product quality, design and technology — the heart of non-price competitiveness. Innovative firms can command a price premium and defend export markets against low-wage rivals.

Both policies raise competitiveness durably by lifting productivity and quality, rather than relying on a temporary exchange-rate change — although each carries a fiscal cost and works only after a time lag, so their size and speed are uncertain.

A sustained improvement in international competitiveness — the ability of a country's firms to compete in global markets — means its exports become better value on price (lower unit costs, a favourable exchange rate) and/or on non-price factors (quality, design, branding). This has significant macroeconomic effects.

The main effects (KAA). More competitive firms sell more exports abroad, raising export revenue. Because exports are a component of aggregate demand, higher net exports raise AD, boosting real output, economic growth and employment. Stronger exports (and firms defending the home market against imports) also improve the current account of the balance of payments — moving it towards surplus or reducing a deficit. Over time, a competitive economy — with skilled labour, good infrastructure and low unit costs — also attracts foreign direct investment (FDI), which adds to productive capacity and further raises productivity, reinforcing the gains.

Evaluation (AO4). The benefits are real but come with qualifications.

First, the export gain depends on the price elasticity of demand for exports; if demand is inelastic, higher competitiveness raises volume only modestly, and if it stems from a weaker currency it may import inflation through dearer inputs.

Second, the source of the competitiveness matters. Gains from higher productivity are durable; gains from a weak currency are temporary and can be reversed by an appreciation.

Third, there is a risk of over-reliance on exports: an economy heavily dependent on exporting is exposed to a global downturn or a fall in world demand, and a large persistent surplus can strain relations with trading partners and push the currency up, eroding the very competitiveness gained.

Fourth, the effect on AD assumes spare capacity; near full capacity, rising export demand may mainly raise inflation rather than output.

Judgement. A sustained improvement in competitiveness is likely to raise exports, growth, jobs and the current-account position, and to attract FDI — a strong set of benefits. But how large and lasting these are depends on the source of the improvement (productivity vs a weak currency), the elasticity of export demand, the spare capacity in the economy and whether the country avoids over-reliance on exports. The most defensible view is that a productivity-based improvement delivers the most durable and balanced benefits.

International competitiveness is the ability of a country's firms to compete in global markets. It can be raised through price channels (lower unit costs, a weaker exchange rate, lower relative inflation) or non-price channels (quality, design, branding, innovation). This essay weighs whether improving productivity is the most effective route.

The case that productivity is most effective (KAA). Labour productivity is output per worker, and it sits at the heart of unit labour costs: unit labour cost = wage ÷ productivity, so if productivity rises faster than wages, unit labour costs fall. Lower unit costs let firms cut export prices (or hold margins), directly raising price competitiveness and improving relative unit labour costs — one of the two key measures. Crucially, productivity gains are usually durable and structural: they come from education, training, R&D, better capital and improved infrastructure, and they cannot easily be reversed. Productivity also feeds non-price competitiveness — the same investment in skills, technology and R&D raises product quality, design and innovation — so it improves competitiveness on both fronts at once. And because higher productivity lowers costs without wage cuts, it raises competitiveness while protecting living standards. For these reasons productivity is often called the only sustainable basis for long-run competitiveness.

The case against — other routes may be more effective in context (KAA + AO4). However, productivity is not the only, nor always the fastest, route. First, a competitive (weaker) exchange rate raises price competitiveness immediately, whereas productivity gains take years to materialise; for an economy needing a quick improvement in its current account, a depreciation may be more 'effective' in the short run. Second, non-price competitiveness — branding, reliability, after-sales service — can be decisive for advanced economies and can be improved by means other than raw productivity. Third, relative inflation and cost control matter: if a country's inflation is persistently higher than rivals', its competitiveness erodes regardless of productivity. Fourth, productivity policies are slow, costly and uncertain: education and R&D carry a heavy fiscal/opportunity cost, work only after long time lags, and may not deliver the expected gains.

Evaluation and judgement. Whether productivity is most effective depends on the time frame and the source of the problem. In the short run, a competitive exchange rate or cost control may raise competitiveness faster; but these are temporary — a depreciation can be reversed and can import inflation, and wage restraint holds down living standards. In the long run, improving productivity is the most effective and sustainable route, because it lowers unit costs and raises non-price quality durably, without sacrificing wages, and it also attracts FDI. The strongest position is therefore that improving productivity is the most effective route to lasting competitiveness, but it is slow, so it is best combined with attention to the exchange rate, relative inflation and non-price quality — and its effectiveness ultimately depends on whether the country's competitiveness problem is short-run (a price/currency issue) or structural (a productivity/quality gap).
