Concept: In macroeconomics, full employment corresponds to potential output or the level of real GDP where labour markets clear given normal frictions. Components: Frictional unemployment (job search/mobility) and structural unemployment (skill/location mismatch) may persist; what disappears is cyclical unemployment caused by deficient demand. Policy link: Demand management (fiscal/monetary policy) aims to close recessionary gaps and return the economy to full employment. Exceeding it can create inflationary pressure as actual output surpasses capacity. Indicators: NAIRU/"natural rate" is often used to approximate full-employment unemployment.
