Document Summary

National income: value of total output and income generated by the production of that output. Nominal national income: national income measured in current dollars. Real national income: measure in constant (base-period) dollars, only changes based on quantity change. Output gap measures the difference between actual and potential (what the economy would produce if its productive resources were full employed) output. If actual output is less than potential output, a recessionary gap exists. If actual output is more than potential output, an inflationary gap exists. Natural rate of unemployment: unemployment rate at the level of full employment. Frictional unemployment: new people entering the labour force + others looking for a better job. Structural unemployment: mismatch between jobs and workers. (the characteristics of labour supply and labour demand. Cyclical unemployment occurs at the difference between the actual level of unemployment and the natural level of unemployment. (when actual=potential output) Real gdp level of employment usually measured as gdp/worker or gdp/hour of work.
