Productivity Drives Trade Competitiveness Steps: - Recall that a current account deficit occurs when a country's imports exceed exports, leading to a negative balance on goods, services, and transfers. - Identify factors affecting trade: exchange rates, inflation, economic growth, and productivity influence export competitiveness and import demand. - Evaluate each option: Undervalued currency or low inflation boosts exports; shrinking economy reduces import demand; low productivity raises costs and harms export viability. - Conclude that declining productivity directly worsens the trade balance by making domestic goods less competitive globally. Why D is correct: - A fall in national productivity increases production costs relative to foreign competitors, reducing export volumes and increasing reliance on cheaper imports, per the balance of payments identity (CA = X - M + NT, where low productivity shrinks X and grows M). Why the others are wrong: - A: Undervalued exchange rate makes exports cheaper and imports costlier, improving the current account. - B: Low inflation enhances price competitiveness, boosting exports and curbing imports. - C: Shrinking economy lowers income, reducing import demand and potentially narrowing the …
