Markets, Equilibrium, & Price How Do You Know When the Price is Right?
Preview 1.Think of a product you recently purchased. 2.On your handout, record the name of the product and the approximate price you paid. Then answer these questions: a.What are some reasons you were willing to buy the product at this price? b.What are some reasons the seller was willing to sell the product at this price? c.Do you think you paid the “right” price for this product?

What Happens When Demand and Supply Meet? In a free market, demand and supply work together to determine price. The interaction of demand and supply drives prices to market equilibrium: Quantity consumers are willing to buy = Quantity producers are willing to sell
Reaching Market Equilibrium On a graph, equilibrium is found at the point where the demand and supply curves interact PriceWatermelons Demanded Watermelons Supplied $ Graph the Supply & Demand for Watermelons
Reaching Market Equilibrium Graph the Supply & Demand for Watermelons PriceWatermelons Demanded Watermelons Supplied $
DEMAND. SUPPLY Equilibrium Price Equilibrium Quantity Price Quantity of Watermelons
So, What is Market Price? Market Price is the price a willing consumer pays to a willing producer for the sale of a good or service. Supply and Demand are like a pair of scissors – it is impossible to determine which blade cuts that paper – the two blades operate in unison.
What Happens When the Price Isn’t Right? Equilibrium Price = “Right” price What happens when producers set a market price that is above or below the equilibrium price? Disequilibrium
