How currency depreciation affects national income and real output

Currency depreciation occurs when the value of a country's currency falls relative to others. This change can stimulate economic activity by altering trade patterns and boosting overall demand.

Key effects on income and output

• Cheaper exports and more expensive imports - Domestic goods become less costly for foreign buyers, while foreign products cost more for local consumers.
• Shift in consumer behaviour - Local buyers often switch to domestically produced items to avoid higher import prices.
• Increased export demand - Overseas customers are more likely to purchase the country's goods due to their lower relative price.
• Rise in net exports - The combination of higher exports and lower imports increases net exports, which forms part of aggregate demand.
• Boost to aggregate demand - Greater net exports lead to higher overall demand in the economy.
• Higher output and income - Firms respond to increased demand by producing more, resulting in greater real output and national income.

The impact of currency depreciation on price levels and employment

While depreciation can drive economic growth, it also influences inflation and the labour market, often creating upward pressure on costs and prices.

Effects on price levels

• Demand-pull inflation - Elevated aggregate demand from stronger net exports can push prices up, especially as the economy nears full capacity.
• Resource pressures - As production expands, shortages of materials or labour may emerge, further increasing costs.
• Higher import costs - Imported goods and raw materials become more expensive, contributing to rises in consumer price indices.
• Increased production expenses - Firms face higher costs for imported inputs, which can be passed on to consumers.
• Reduced price competition - With fewer cheap imports, domestic firms may feel less need to keep their prices low.

Effects on employment

• Expanded hiring - Companies serving domestic and export markets often need more workers to handle increased production.
• Lower cyclical unemployment - As output grows to meet demand, fewer people are out of work due to economic slowdowns.

How currency appreciation affects national income and real output

Currency appreciation happens when a country's currency rises in value against others. This typically reduces the competitiveness of domestic goods abroad and can slow economic activity.

Key effects on income and output

• More expensive exports and cheaper imports - Domestic products cost more for foreign buyers, while imported goods become less expensive for locals.
• Decline in demand for domestic goods - Both local and international consumers may prefer cheaper foreign alternatives.
• Fall in net exports - Exports decrease while imports rise, leading to lower net exports.
• Reduced aggregate demand - The drop in net exports contributes to weaker overall demand in the economy.
• Lower output and income - Firms produce less in response to reduced demand, resulting in decreased real output and national income.
• Risk of economic slowdown - Persistent appreciation may trigger a recession if demand falls sharply.

The impact of currency appreciation on inflation and unemployment

Appreciation can help control inflation by easing cost pressures, but it often comes at the expense of higher unemployment as economic activity contracts.

Effects on inflation

• Eased inflationary pressures - When the economy is near full capacity, slower demand growth helps prevent overheating.
• Slower aggregate demand expansion - Reduced net exports limit the pace at which demand increases.
• Rightward shift in aggregate supply - Cheaper imported raw materials lower production costs for firms.
• Lower prices for imports - Finished imported goods become more affordable, directly reducing consumer prices.
• Greater competitive pressure - Domestic firms must keep prices in check to compete with cheaper imports.

Effects on unemployment

• Rising unemployment rates - Decreased aggregate demand often leads to higher joblessness.
• Workforce reductions - Firms may cut staff through natural attrition or redundancies to match lower production needs.
