Microeconomics Homework Help

About Microeconomics

Microeconomics looks at individual markets: how demand and supply set a price, how consumers and firms decide, and what happens when a market fails. The questions here are mostly demand and supply schedules and curves, elasticity calculations, cost and revenue tables, and the behaviour of firms under different market structures.

Popular topics in Microeconomics

• Demand & Supply

  The laws of demand and supply, schedules and curves, shifts against movements, and market equilibrium.

• Elasticity

  Price, income and cross elasticity, the formulae, interpreting the value, and why elasticity matters for revenue.

• Market Equilibrium

  Finding equilibrium price and quantity, surpluses and shortages, and the effect of taxes and subsidies.

• Costs & Revenue

  Fixed, variable, total, average and marginal cost, total and marginal revenue, and the profit-maximising rule.

• Market Structures

  Perfect competition, monopoly, oligopoly and monopolistic competition, and how price and output differ.

• Consumer Behaviour

  Utility, marginal utility and diminishing returns, consumer surplus and the budget constraint.

• Production

  Factors of production, total and marginal physical product, returns to scale and the short and long run.

• Market Failure

  Externalities, public goods, imperfect information, and the case for government intervention.

How ScanSolve helps with Microeconomics

ScanSolve answers with the diagram in words: which curve shifts, in which direction, and what happens to price and quantity as a result — the analysis that carries the marks, rather than the definition. Calculations (elasticity, equilibrium, marginal cost from a table) are shown with the formula and the substitution.

Where a question asks for evaluation, the answer gives the effect and then its limits: whose surplus changes, what depends on elasticity, and what the assumption is doing. Schedules and tables are completed column by column so each figure can be traced.

Study tips for Microeconomics

1. 01

   Distinguish a shift from a movement along the curve. Almost every demand-and-supply mark scheme hangs on that distinction.

2. 02

   Draw the diagram before you write, even in a written answer. Then describe what you drew.

3. 03

   Learn the elasticity formula and what the sign tells you: negative for price elasticity of demand, positive for a normal good's income elasticity.

4. 04

   For "evaluate", give the effect, then what it depends on. An unqualified effect is only half the answer.
