1. MEASURING ECONOMIC ACTIVITY
This task is performed by the compilers of Zimbabwe’s national accounts at the RBZ, Ministry of Finance and CSO - they draw up accounts for the economy as a whole.
Economic activity is measured by various indicators or variables which include National Income, GDP, GNP, Inflation and many others.
The various measures of economic activity indicate fluctuations in economic activity and these fluctuations set the conditions within which the market, industry and company must operate.
