Which statement best defines the natural rate of output?

• A. The highest level of nominal GDP that can be achieved in the economy.
• B. The highest level of real GDP that can be sustained over the long term.
• C. The current year's GDP growth rate.
• D. The total potential energy production capacity.

Answer: (B)

The main concept here is potential output—the amount of goods and services an economy can produce over the long run given its available resources and technology. The natural rate of output is about real GDP, because it reflects the economy’s actual production after removing price effects and focuses on sustainable quantity rather than price levels. The description that best fits this idea is the highest level of real GDP that can be sustained over the long term, since it defines the economy’s capacity to produce without fueling inflationary pressures. Nominal GDP changes with prices, not just how much is produced; a single year’s GDP growth rate is a short-run snapshot, not the long-run capacity; and total potential energy production capacity doesn’t directly describe macroeconomic output.
