The National Economy and Government
The National Economy and Government
This domain examines macro-economic objectives, the circular flow, inflation, unemployment, growth and the policy tools government and the central bank use. In Botswana, the Bank of Botswana conducts monetary policy with an inflation objective range of 3–6%, while government uses fiscal policy through taxation and spending.
Core rules
- GDP measures output produced within a country; GDP per capita divides GDP by population.
- Inflation is a sustained rise in the general price level. It redistributes income between borrowers and savers and creates uncertainty.
- Unemployment types include frictional, structural, seasonal and cyclical; the causes require different policies.
- Fiscal policy uses government spending and taxation. Monetary policy uses interest rates, money supply and exchange-rate measures.
- Leakages from the circular flow include saving, taxation and imports; injections include investment, government spending and exports.
Worked example
A saver earns 9% nominal interest while inflation is 6%. The approximate real interest rate is 9% − 6% = 3%; more precisely, (1.09 ÷ 1.06) − 1 ≈ 2.8%. The saver’s purchasing power rises only by about 2.8%, not 9%. If inflation rose above the nominal rate, the real return would be negative. The reasoning matters because exam questions often reward the distinction between money values and real values.
Traps that cost marks
- Treating nominal values as real values.
- Confusing GDP with GNP.
- Saying all inflation is harmful in every case.
- Mixing fiscal policy with monetary policy.
- Blaming one unemployment type for a cause that fits another.
