Market Forces: Demand and Supply
An investigation into the laws of demand and supply and how they interact to determine market equilibrium. Students will model price changes based on market shifts.
TL;DR:This topic explores the mechanics of the price mechanism through the laws of demand and supply. Students examine how price changes influence consumer behaviour and producer output, leading to the concept of market equilibrium. Understanding these forces is essential for grasping how prices are set in a free market and why they fluctuate in response to external shocks.
About This Topic
This topic explores the mechanics of the price mechanism through the laws of demand and supply. Students examine how price changes influence consumer behaviour and producer output, leading to the concept of market equilibrium. Understanding these forces is essential for grasping how prices are set in a free market and why they fluctuate in response to external shocks.
Beyond basic curves, students investigate elasticity, measuring how sensitive consumers and producers are to price changes. This is a critical skill for business students, as it dictates pricing strategies and tax policies in Ireland. Students grasp this concept faster through structured discussion and peer explanation of real-world price hikes.
Key Questions
- What factors cause a shift in the demand curve?
- How do producers respond to changes in price?
- How is market equilibrium achieved?
Watch Out for These Misconceptions
Common MisconceptionA change in price causes a shift in the demand curve.
What to Teach Instead
A change in price causes a movement along the curve, not a shift of the curve itself. Using interactive graphing tools or physical 'human graphs' helps students see that only non-price factors (like tastes or income) move the entire line.
Common MisconceptionSupply and demand only apply to physical goods.
What to Teach Instead
These forces apply to services and the labour market as well. Peer discussions about part-time job wages can help students see how the supply of student labour and the demand from local businesses set the 'price' of work.

Market Simulation: The Trading Floor
Assign students roles as buyers and sellers of a specific commodity, like concert tickets. As the teacher introduces 'shocks' (e.g., a popular artist announces a final tour), students must negotiate new prices and observe how the equilibrium point shifts in real-time.
Gallery Walk
Determinants of Demand and Supply
Post large sheets around the room with different scenarios, such as an increase in Irish income tax or a new technology in farming. Students move in groups to draw the resulting curve shift and explain the reasoning behind the movement.
Inquiry Circle
Elasticity in the Real World
Groups research the price elasticity of different products, such as petrol, luxury watches, and bread. They must present a case for why certain items are price inelastic in the Irish market and how this affects government VAT revenue.

Introduction to Economic Concepts
Students explore the foundational economic concepts of scarcity, choice, and opportunity cost. They will analyse how these principles affect decision-making for individuals and businesses.
