What are the equilibrium conditions in this market (that is, find d s equilibrium P and Q) and what are the maximum gains from trade in this market? 3 of 6 2/19/11 7:48 AM Quiz: <span class="invisibleNumber03"></span>Homework Set 3 http://angel.bfwpub.com/section/content/default.asp?WCI=pgT... Answer: Equilibrium price is $46, and equilibrium quantity is 42. Total gains from trade are $735. 26. The following diagram shows the supply and demand for wheat. Part 1: Use the area tool provided to identify the producer surplus when the market is in equilibrium. Identify this area on the graph as area A. Part 2: Use the area tool provided to identify the consumer surplus when the market is in equilibrium. Identify this area on the graph as area B. 27. 4 of 6 2/19/11 7:48 AM Quiz: <span class="invisibleNumber03"></span>Homework Set 3 http://angel.bfwpub.com/section/content/default.asp?WCI=pgT... The table below refers to the daily supply and demand schedule for pizza in a small college town. Part 1: Use the multi-point line tool to plot the demand curve (D) and the supply curve (S) for pizzas. Part 2: Use the double drop line to identify the equilibrium price and quantity of pizza (E). Part 3: Suppose that enrollment at the college increases and, as a result, the quantity of pizzas demanded at each price increases by 20 pizzas. Use the multi-point line tool to draw the new demand for pizza (D2). Part 4: Use a drop line to identify the new equilibrium price and quantity of pizza (E2). Price of pizza Quantity of pizza supplied (per day) Quantity of pizza demanded (per day) $25 100 20 $20 80 40 $15 60 60 $10 40 80 $5 20 100 28. 5 of 6 2/19/11 7:48 AM Quiz: <span class="invisibleNumber03"></span>Homework Set 3 http://angel.bfwpub.com/section/content/default.asp?WCI=pgT... The accompanying graph shows the supply and demand for dry cleaning services as the market was 10 years ago, with price and quantity indicated. The supply of dry cleaning services has decreased recently as more regulations to protect environmental quality have been added. Part 1: Use the copy tool to show how the supply has shifted. Label the new curve S2. Part 2: Use the drop line tool to indicate the new equilibrium price and quantity. Label this point E2. Part 3: Use an area tool to indicate the amount of consumer surplus at the new equilibrium. Label the area Consumer surplus. 6 of 6 2/19/11 7:48 AM
