a) Determine:
Price of Equilibrium_
and Quantity of Equilibrium
b) Determine the effect of $60 Price Ceiling.
Is it binding? Why?
Will it cause Shortage or Surplus? And by how much?
c) Determine the effect of $120 Price Floor.
Is it binding? Why?
Will it cause Shortage or Surplus? And by how much?
Market researches have studied the market for milk,and their estimates for the supply of and the demand for milk per month are as follows:a.Using the data,graph the demand for and the supply for milk.Identify the equilibrium point as E,and use dotted lines to connect E to the equilibrium price onthe price axis and the equilibrium quantity on the quantity axis.b.Suppose the government enacts amilk price support of $8per gallon.Indicate this action on your graph,and explain the effect on the milk market?Why would the government establish such a price support?c.Now assume the government decides to set a price ceiling of $4 dollar per gallon.Show and explain how this legal price effects your graph of the milk market.What objective could the government be trying to achieve by establishing such a price ceiling?
I can seem to figure out the last two questions I bolded:
Why does the demand curve slope downward? Why does the supply curve slope upward? Given the demand and supply schedules below:
Price (dollars per CD)
Quantity Demanded (per day)
Quantity Supplied (per day)

100
6.00
250

What is the market equilibrium?
If the price of CD is $6.00, describe the situation in the CD market. Explain how market equilibrium is restored.
A rise in incomes increases the quantity of CDs demanded by 100 a day at each price. What is the new equilibrium and how does the market adjust?
A rise in the number of recording studios increases the quantity of CDs supplied by 75 a day at each price. People download more music from the Internet and the quantity demanded of CDs decreases by 25 a day at each price. With no change in incomes, what is the new equilibrium and how does the market adjust?

- Housing policy analysts debate the best way to increase the number of housing units available to low-income households. One strategy-the demand-side strategy-is to provide people with housing vouchers, paid by the government, that can be used to rent housing supplied by the private market. Another-a supply-side strategy—is to have the government subsidize housing suppliers or to build public housing. Using supply and demand curves, think about the market outcomes of the supply-side and demand-side strategies. Which side do you support? Explain why.arrow_forwardExplain, using demand and supply analysis, the impact on the market for chips if a doctors discover that eating chips makes people smarter and at the same time the wages of the workers in the chips factories increase.
