In the market for widgets, the demand and supply curves are given, respectively, by QD = 200 - 10P QS = -70 + 5P On a sheet of paper, do all of the following: 1. Calculate the equilibrium price and quantity. 2. What is the highest price any one consumer would ever be willing to pay - this is the same as asking what is P equal to if Qº=0? More formally, this is the point on the demand curve that intersects the P-axis. 3. What is lowest price any one firm would ever be willing to accept - this is the same as asking what is P equal to if QS =0? More formally, this is the point on the supply curve that intersects the P-axis. 4. Graph the demand and supply curves with price on the y-axis (vertical axis) and quantity on the x-axis (horizontal axis). Your graph should include ALL of the following: I. The curves (.e., make sure it is clear which curve is the inverse demand curve and which curve is the inverse supply curve). II. The axes (this is easy: your x-axis should be labeled as quantity (or Q) and your y-axis should be labeled as price (or P) III. The y-intercepts for both demand and supply (this is what you computed in 2 and 3). IV. The equilibrium price and quantity (you computed this in 1) 5. Calculate consumer surplus. 6. Calculate producer surplus. 7. Calculate total surplus. 8. In your graph you drew in 4, shade and label the area for consumer surplus and the area for producer surplus. Make sure it is clear which one is which. 9. Suppose that average income of all consumers increases. Do/answer the following: I. Will this affect demand or supply? II. Given your answer to I, will it be a movement along the curve? Or a shift in the curve? III. Give your answer to II, depict the change that occurs in your graph. 10. At the original equilibrium price and quantity, the price elasticity of demand is equal to -9. Given this, if the market price were to increase by 1%, by what percent would you expect quantity demanded to change by? Is it an increase or decrease?
