Demand

Bayani Gaba-gaba

Why does a shop drop its price when sales are slow, and why does a concert ticket cost more the moment everyone wants to go? Behind both lies one of the most powerful ideas in economics: demand. It describes exactly how the quantity buyers want changes as the price moves, and it is the first half of the engine that sets every price in a market.

In this lesson you will define demand, see how the choices of single buyers add up to the demand of a whole market, and learn to draw and read the demand diagram with confidence. You will also tell apart a movement along the curve from a shift of the whole curve, the distinction that earns the most marks.

Price does not appear from nowhere. It comes from the interaction of demand and supply, and demand is the buyers' side of that story. Once you can draw and interpret a demand curve, you can explain price changes, predict how much a price cut will raise sales, and analyse the effect of almost any event, from a heatwave to a tax. Demand is the foundation the whole allocation-of-resources section is built on.
