Study Notes
Exchange rates affect macroeconomic objectives by influencing exports, imports, inflation, economic growth, unemployment, and living standards.
- Appreciation — An increase in the value of a currency relative to others. Example: Domestic exports become more expensive, reducing demand and export revenue.
- Depreciation — A decrease in the value of a currency relative to others. Example: Domestic exports become cheaper, increasing demand and export revenue.
- Net Exports (X-M) — The value of exports minus the value of imports. Example: Appreciation leads to a fall in net exports.
- Demand-Pull Inflation — Inflation caused by an increase in aggregate demand. Example: Depreciation can increase AD, leading to demand-pull inflation.
- Cost-Push Inflation — Inflation caused by an increase in the cost of production. Example: Depreciation increases import costs, leading to cost-push inflation.
