1) Complete the first two rows of the following table by indicating which areas on the graph represent consumer surplus and producer surplus prior to the shift in supply. Then complete the second two rows by indicating which areas on the graph represent consumer surplus and producer surplus after the change in production costs. Check all that apply.   A B C D E F G   Initial Consumer Surplus                 Initial Producer Surplus                 New Consumer Surplus                 New Producer Surplus                 2) True or False: Consumers are hurt most by rising production costs when the supply of silverware is very elastic. True False

8. Total economic surplus The following diagram shows supply and demand in the market for tablets. Use the black point (plus symbol) to indicate the equilibrium price and quantity of tablets. Then use the green point (triangle symbol) to fill the area representing consumer surplus, and use the purple point (diamond symbol) to fill the area representing producer surplus.

The graph shows the market for ice cream cones. On the graph, draw a shape that shows the producer surplus at market equilibrium. Producer surplus equals $ Enter your answer in dollars and cents (i.e. round at the second decimal place). 6.00- 5.50- 5.00 4.50- 4.00- 3.50- 3.00 2.50- 2.00 1.50- 1.00- 0.50 0.00 0 Price (dollars per ice cream cone) 5 10 15 20 30 25 Quantity (ice cream cones per day) S D 35 2

2. 3-5: Attaining Market Equilibrium *3* The Wall Street Journal of March 20, 2020, reported on the "large surplus of oil" as there is not enough storage capacity to hold the refined oil. Assuming the price of oil is set by competitive market forces, which of the following sequence of events accurately describes how the surplus of oil would be eliminated? As price decreases, the: Quantity demanded decreases, quantity supplied increases, and a new equilibrium will be reached. O Quantity demanded increases, quantity supplied increases, and a new equilibrium will be reached. O Demand decreases, supply increases, and a new equilibrium will be reached. O Demand increases, supply decreases, and a new equilibrium will be reached. O Quantity demanded increases, quantity supplied decreases, and a new equilibrium will be reached.

8. Consider the market for the Mona Lisa painting given by the following demand and supply curves: D: P = 1000-50QD and S: Qs=1 a. Draw the market for Mona Lisa paintings below. Label graph and axes. b. Calculate the equilibrium price and quantity of Mona Lisa paintings. Label P* and Q* on your graph from part a. C. Calculate consumer surplus and producer surplus. Label these (CS and PS) on your graph from part a. Suppose the French government imposed a $300 tax on buyers of Mona Lisa paintings. d. On the following graph, show the effect of the tax. Clearly label PBUYER PSELLER P, Q, QTAX CSTAX PSTAX, the tax revenue (TR), and DWL. (Here CSTAX PSTAX refer to consumer and producer surplus after the tax is imposed.) Calculate consumer surplus (CSTAX), producer surplus (PSTAX), deadweight loss (DWL), and the total tax revenue (TR) under the new tax. I e.

In a supply-and-demand graph, producer surplus can be pictured as the Select one: a. vertical intercept of the supply curve. b. area between the demand curve and the supply curve to the left of equilibrium output. c. area under the supply curve to the left of equilibrium output. d. area under the demand curve to the left of equilibrium output. e. area between the equilibrium price line and the supply curve to the left of equilibrium output.

Question 29 Describe where producer surplus is on the graph (use words or you can also draw and attach a drawing or photo of a drawing).

Here’s a quick problem to test whether you really understand what producer surplus and consumer surplus mean, rather than just relying on the geometry of demand and supply. For each of the two diagrams that follow, calculate producer surplus, consumer surplus, and total surplus. Assume the curves are perfectly vertical and perfectly horizontal.

© Macmillan Learning b. How much does this new technology increase consumer surplus? Increase in consumer surplus: $ 1050 Increase in producer surplus: $ Incorrect c. How much does this new technology increase producer surplus? 1050 Incorrect d. How much does this new technology increase total (or social) surplus?
