Comprehensive Syllabus Study Notes
• Inflation Defined: A persistent and appreciable rise in the general price level of goods and services over time, resulting in a fall in the purchasing power of money.
• Types & Causes of Inflation:
- Demand-Pull Inflation: Occurs when Aggregate Demand exceeds Aggregate Supply at full employment ("too much money chasing too few goods").
- Cost-Push Inflation: Caused by rising production costs (wage increases, electricity tariff hikes, fuel price increases) pushing up prices.
- Imported Inflation: Caused by depreciation of the local currency (Ghana Cedi) against major trading currencies, raising the domestic cost of imported goods (crude oil, machinery, rice).
• Effects of Inflation:
- Losers: Fixed-income earners (pensioners, salaried civil servants), lenders/creditors (paid back in devalued currency), cash savers.
- Gainers: Debtors/borrowers, real estate owners, equity investors.
• Measures to Control Inflation:
- Monetary Policy: Raising the Monetary Policy Rate (MPR), selling Treasury Bills (OMO), increasing reserve requirements.
- Fiscal Policy: Cutting government expenditure, increasing direct taxes to reduce disposable income.
- Supply-Side: Subsidizing agricultural inputs to boost local food production.

Core Takeaway:
In WASSCE: Debtors GAIN during inflation because the real value of the debt they repay is lower; Creditors LOSE because the money received buys less.
WAEC / WASSCE Examiner Tips
- In WASSCE: Debtors GAIN during inflation because the real value of the debt they repay is lower; Creditors LOSE because the money received buys less.
Common Candidate Pitfalls & Errors to Avoid
- Weighting the consumer basket with current-year quantities when a fixed base-year basket is required.
- Reporting the index number as the inflation rate without subtracting 100.
- Explaining inflation only through too much money and ignoring cost push from import prices and wages.
- Assuming all consumers are hurt equally, when debtors gain and creditors lose.
- Advising tight money without noting that higher interest rates also raise the cost of servicing public debt.
