Fundamentals of economics

Section 1 of Module 12 (up to 20% of the paper) tests the macroeconomics an adviser needs: measuring output, inflation and unemployment, fiscal and monetary policy (Bank Negara Malaysia's OPR and tools), the balance of payments and exchange rates, the business cycle and the indicators investors watch. Expect definitions plus short calculations (GDP, real GDP, inflation, multipliers, cross rates).

Must-know for the exam

GDP (expenditure) = C + I + G + (X − M).
Real GDP = nominal GDP ÷ (deflator ÷ 100).
Inflation = (CPI now ÷ CPI a year ago − 1) × 100; Malaysia's CPI is compiled by DOSM.
Simple spending multiplier = 1 ÷ (1 − MPC): MPC 0.75 gives 4.
Unemployment rate = unemployed ÷ labour force (not the whole working-age population).
Bank Negara Malaysia's Monetary Policy Committee sets the OPR and meets six times a year (BNM, 2026 schedule).
Monetary tools: OPR, open market operations, Statutory Reserve Requirement. Fiscal tools: government spending and taxes.
Dividends paid abroad are current-account (primary income) items; FDI and portfolio flows are financial-account items.
Cross rate MYR per SGD = (MYR per USD) ÷ (SGD per USD).
PMI above 50 means expansion; below 50 contraction.

Traps that cost marks

Adding imports, or forgetting to deduct them, when they are already counted inside C, I and G.
Multiplying by the deflator, which inflates rather than deflates.
Quoting the point change in the index as the percentage change.
Dividing by the MPC instead of by (1 − MPC).
Using the working-age population rather than the labour force as the denominator.
Confusing fiscal authorities with the central bank.
Mixing up fiscal and monetary tools.
Thinking easier money lowers inflation.

Measuring the economy

Measure	Formula	Example
GDP (expenditure)	C + I + G + (X − M)	900 + 300 + 250 + 100 = RM1,550bn
Real GDP	Nominal ÷ (deflator ÷ 100)	1,980 ÷ 1.10 = RM1,800bn
Inflation	CPI1 ÷ CPI0 − 1	131.2 ÷ 128.0 − 1 = 2.5%
Unemployment rate	Unemployed ÷ labour force	0.51 ÷ 17.0 = 3.0%
Nominal growth	(1 + real) × (1 + prices) − 1	1.045 × 1.02 − 1 = 6.6%

GDP measures output produced within the country; GNI adds net income from abroad.

Trap: adding imports, multiplying by the deflator, or dividing unemployment by the working-age population.

Takeaway: know each formula's denominator; most wrong options use the wrong one.

Fiscal and monetary policy

Fiscal policy is government spending and taxation; a budget deficit is spending above revenue in a year (debt is the stock). Heavy government borrowing can crowd out private investment by raising rates. Automatic stabilisers (progressive taxes, unemployment support) cushion the cycle without new decisions.
