Summary
Macroeconomic problems are interconnected, with changes in one area often affecting others. Understanding these relationships helps in analyzing economic policies and outcomes.
- Internal Value of Money — the purchasing power of a currency within a country. Example: Inflation reduces the internal value, making goods more expensive domestically.
- External Value of Money — the exchange rate of a currency compared to others. Example: A decrease in the external value makes imports more expensive.

- Inflation — a general increase in prices and fall in the purchasing value of money. Example: Inflation can be caused by increased demand or rising production costs.
- Unemployment — the state of being jobless and actively looking for work. Example: The Phillips curve shows an inverse relationship between inflation and unemployment.
