The Fundamentals of Economics for CMA Foundation

What this chapter covers

The Fundamentals of Economics: topics in the order to study them

1. 1Meaning and Scope of EconomicsStart here to learn the core definitions and the split between micro and macro, which every later topic uses.
2. 2Basic Economic Problems and ScarcityScarcity and choice explain why economics exists, and opportunity cost is the idea behind the central problems.
3. 3Economic SystemsOnce you know the central problems, you can see how capitalist, socialist and mixed systems solve them differently.
4. 4Demand and Law of DemandDemand is the first half of the market and the easiest part to learn, so it comes before supply.
5. 5Supply and Law of SupplySupply mirrors demand, so learning it right after makes comparing the two simple.
6. 6Elasticity of Demand and SupplyElasticity measures how strongly quantity responds to price, so you need demand and supply clear first.
7. 7Market Equilibrium and Price DeterminationThis ties demand and supply together, so it is best studied last, once both curves and their shifts are familiar.

How to prepare The Fundamentals of Economics

1. Read the first three topics once for understanding. Note each definition in your own words and make a short list of the features of each economic system.
2. Learn the law of demand and the law of supply together. For each, write down the assumption (other things remain equal) and the exceptions or limits.
3. Separate movement along a curve from a shift of the curve. Make a list of what causes each, because the exam often tests this.
4. For elasticity, memorise the formula Ed = % change in quantity demanded ÷ % change in price, and the meaning of values above 1, equal to 1 and below 1. Practise five or six simple calculations.
5. Draw equilibrium graphs by hand. Shift demand or supply one at a time and note what happens to price and quantity.
6. Solve topic-wise MCQs after each topic, then a mixed set. For every wrong answer, write the rule you missed in one line.
7. In the last two days, revise only your one-line notes and redo the questions you got wrong.

Common mistakes in The Fundamentals of Economics

• Confusing a movement along the demand curve with a shift of the curve.

  Fix: Ask what changed. If only the good's own price changed, it is a movement along the curve. If income, tastes, related prices or expectations changed, the curve shifts.

• Forgetting the phrase 'other things remaining equal' in the laws of demand and supply.

  Fix: Always attach the assumption to the law. Options that state the law without conditions or that overstate it are often wrong.

• Mixing up elastic and inelastic ranges in elasticity questions.

  Fix: Remember that above 1 means quantity responds more than price (elastic) and below 1 means it responds less (inelastic). Recompute a quick example to check.

• Getting the direction wrong when both demand and supply change.

  Fix: Shift one curve at a time, note the effect on price and quantity, then combine. If effects on one variable conflict, the result depends on the size of the shifts.

• Mixing up the features of different economic systems.

  Fix: Make a small comparison list covering ownership, role of the government, and how decisions are made, then revise it with practice MCQs.

• Treating scarcity as meaning poverty or lack of goods.

  Fix: Remember that scarcity is the gap between unlimited wants and limited resources. It exists in every economy, rich or poor.

Last-day revision: The Fundamentals of Economics

• ✓Economics studies how people choose to use scarce resources that have alternative uses.
• ✓Microeconomics deals with individual units such as a consumer or firm; macroeconomics deals with the economy as a whole.
• ✓Scarcity means wants are unlimited but resources are limited, which forces choice.
• ✓Opportunity cost is the value of the next best alternative given up.
• ✓The central problems are what to produce, how to produce and for whom to produce.
• ✓Capitalism relies on markets and private ownership; socialism on state ownership and planning; a mixed economy combines both.
• ✓Law of demand: other things equal, when price falls quantity demanded rises, and the demand curve slopes downward.
• ✓Law of supply: other things equal, when price rises quantity supplied rises, and the supply curve slopes upward.
• ✓A change in price causes movement along the curve; a change in other factors shifts the curve.
• ✓Price elasticity of demand = % change in quantity demanded ÷ % change in price; above 1 is elastic, below 1 is inelastic.
• ✓Equilibrium price is where quantity demanded equals quantity supplied.
• ✓If demand rises with supply unchanged, equilibrium price and quantity both rise.
