subsidy

Imagine a government that wants its farmers' grain to dominate world markets. It writes them a cheque for every tonne they sell abroad. Now those farmers can charge foreign buyers a low, competitive price and still come out ahead, because the state is topping up their earnings. The grain becomes artificially cheap on the world market — not because the farmers got more efficient, but because taxpayers are footing part of the bill. That government payment to help a domestic industry sell, especially abroad, is a subsidy.

A subsidy is a payment or other financial help from the government to producers, lowering their costs or boosting their revenue. An export subsidy specifically rewards selling abroad; a production subsidy supports output whether sold at home or overseas. The effect on trade is the mirror image of a tariff: rather than taxing imports to shrink trade, a subsidy props up exports to expand a favoured industry's sales. It can be a direct cash payment, a tax break, a cheap government loan, or below-cost inputs like subsidised electricity. Whatever the form, it shifts the playing field by having the public purse pay part of a private producer's costs.

Subsidies have winners and losers just like tariffs. The subsidised industry and its workers gain; the country's taxpayers foot the bill; and foreign producers who compete with the now-cheaper goods are hurt — which is why export subsidies are widely viewed as an unfair trade practice and are tightly restricted under World Trade Organization rules. There is a subtler cost at home too: by propping up one industry, a subsidy quietly pulls workers and capital away from others that might use them better, and it can keep inefficient firms alive. Subsidies are not automatically bad — they can be justified for genuine public benefits like basic research or clean energy — but as a trade weapon they shift costs onto taxpayers and trading partners alike.
