Output Gaps

An output gap is present when there is a difference between the actual level of real GDP in an economy and the potential level of real GDP (when all factors of production are fully employed).

Negative output gap

Negative output gap

  • A negative output gap is defined as: “when the actual level of real GDP is less than the potential underlying level of real GDP”.
  • Negative output gaps means there is 'spare capacity'. So there will be unemployment (demand-deficient), and demand-pull inflationary pressure will be low because there are lots of resources and factors of production not being used.
Positive output gap

Positive output gap

  • A positive output gap is defined as: “when the actual level of real GDP is greater than the potential underlying level of real GDP”.
  • Positive output gaps mean that an economy is temporarily producing beyond its productive potential. This is only possible for a short time, and leads to workers being paid overtime, and workers and machines being over-used. This causes inflationary pressure as wages and costs rise.
