How prices allocate resources
Suppose that there are three beachfront parcels of land available for sale in Asilomar, and six people who would each like to purchase one parcel. Assume that the parcels are essentially identical and that the minimum selling price of each is $445,000. The following table states each person’s willingness and ability to purchase a parcel.

Assume that the three beachfront parcels are sold to the people that you indicated in the previous section. Suppose that a few days after the last of those beachfront parcels is sold, another essentially identical beachfront parcel becomes available for sale at a minimum price of $432,500. This fourth parcel be sold because will purchase it from the seller for at least the minimum price.

True or False: A price ceiling below $25 per box is not a binding price ceiling in this market. (Economists call a price ceiling that prevents the market from reaching equilibrium a binding price ceiling.)
True
(4)The effects of rent control
Suppose the following graph shows the demand for, and supply of, apartments in New York City.
Use the black point (plus symbol) to indicate the equilibrium monthly rent and quantity of apartments in the absence of price controls. Then use the green point (triangle symbol) to fill the area representing consumers’ surplus, and use the purple point (diamond symbol) to fill the area representing producers’ surplus.

Suppose that the government decides to impose a rent control of $1,900 per month on rental apartments in New York City. On the following graph, use the green point (triangle symbol) to shade the area representing consumers’ surplus in the presence of rent control. Use the purple point (diamond symbol) to shade the area representing producers’ surplus after the rent control. Then use the grey point (star symbol) to shade the area representing deadweight loss resulting from the rent control.

Taxes and the impact on relative price
In her school’s food court, Martha notices that a carton of juice costs $1.75 and a can of soda costs $1.25. Since Martha just finished studying for an economics exam, she immediately calculates that the relative price of a carton of juice is per .
Suppose that school administrators want to encourage healthy choices and decide to impose a $0.25 price increase on cans of soda. Given that the absolute price of a carton of juice is unchanged, the relative price of a carton of juice .
