Measuring Domestic Output

Definition:
- Net exports is calculated using the formula:
  \text{Net exports} = \text{exports} - \text{imports}
Exports:
- Goods and services produced within the borders of the U.S.
Imports:
- Goods and services produced outside the U.S. but purchased by U.S. consumers.
Impact on GDP:
- Higher exports lead to increased GDP and employment.
- Higher employment increases domestic production.
Negative Net Exports:
- A negative net export figure indicates a greater demand for goods produced outside the U.S.
- Over time, the U.S. may struggle to compete with foreign products.
- Economic growth can be negatively impacted as U.S. goods may lose market competitiveness.

Nominal GDP:
- Represents the total dollar value of all goods and services produced within U.S. borders during a specific period.
Real GDP:
- Considered more reliable as it reflects production within U.S. borders without the distortions caused by inflation or employment changes.

- Provides an overall price level of the economy and helps govern both nominal and real GDP by evaluating goods, services, and economic growth.
