Policies to correct imbalances in the current account of the balance of payments

A persistent current account deficit, where the value of imports of goods and services exceeds exports, poses significant macroeconomic challenges. To correct this imbalance, governments can employ two main categories of policies. The first, expenditure-reducing policies, aim to lower aggregate demand (AD) across the economy, thereby reducing demand for imports. The second, expenditure-switching policies, seek to encourage domestic consumers and firms to switch their spending from foreign-made goods to domestically-produced alternatives. A third, longer-term approach involves supply-side policies designed to enhance the international competitiveness of a country's industries. The choice and effectiveness of these policies depend on the underlying causes of the deficit and other macroeconomic objectives. It is also important to consider how the deficit is financed; a deficit financed by long-term foreign direct investment (FDI) that boosts productive capacity may be more sustainable than one financed by short-term borrowing.

These policies work by deliberately dampening aggregate demand, which reduces overall spending in the economy, including spending on imported goods and services. The primary tools are contractionary fiscal policy and contractionary monetary policy. Fiscal measures include increasing direct and indirect taxes (reducing disposable income and raising prices) or cutting government spending. Monetary measures involve the central bank raising interest rates, which makes borrowing more expensive for consumers and firms, discouraging consumption and investment. While effective at cutting import spending, these policies are a blunt instrument that can cause a recession, leading to higher unemployment and slower economic growth, creating a significant policy conflict.

Expenditure-switching policies aim to alter the relative prices of domestic and foreign goods to encourage a switch in spending patterns. The main policy is a devaluation or depreciation of the currency's exchange rate. This makes a country's exports cheaper for foreign buyers and its imports more expensive for domestic buyers, aiming to increase export revenue and decrease import expenditure. Another approach is protectionism, using tariffs (taxes on imports), quotas (limits on import quantities), and other trade barriers. While a weaker currency can be effective, its success depends on the Marshall-Lerner condition. Protectionism is often criticised for inviting retaliation from trading partners and protecting inefficient domestic industries.

Unlike demand-side policies, supply-side policies offer a long-term solution by tackling the root causes of a lack of competitiveness. These policies aim to increase the efficiency, productivity, and quality of domestic industries, thereby making their exports more desirable and competitive on the world stage without needing to devalue the currency. Examples include investment in education and training to improve labour skills, deregulation to reduce business costs, privatisation to promote efficiency, and incentives for research and development (R&D) to foster innovation. While these policies are highly effective in the long run and avoid conflicts with other objectives like inflation, their primary drawback is the significant time lag before their effects are felt.
