When the price is above the equilibrium, explain

how market forces move the market price to

equilibrium. Do the same when the price is below the

equilibrium.

Short Answer

Expert verified

yes, if prices are above the equilibrium level, there would be surplus

and if the price is below the equilibrium level, there would be a shortage.

Step by step solution

01

Step 1. Concept 

Equilibrium refers to the point where,

Quantity demanded = Quantity supplied.

If prices are above equilibrium level,

supply exceeds quantity demanded.

If prices are below equilibrium level,

quantity demanded exceed supply.


02

Step 2. Explanation

When the price is above the equilibrium, the quantity supplied would be greater than the quantity demaned. This would create a surplus in the market. Such unsold surplus forces the sellers to reduce quantity supplied, thus bringing back market to the equilbrium level.

When prices are below the equilbrium, the quantity demanded would be higher than the quantity supplied. This would create a shortage in the market. This shortage would force sellers to increase quantity supplied bringing the market back to the equilbrium level.

Table 3.10 shows the supply and demand for movie tickets in a city. Graph demand and supply and identify the equilibrium. Then calculate in a table and graph the effect of the following two changes.

(a) Three new nightclubs open. They offer decent bands and have no cover charge, but make their money by selling food and drink. As a result, demand for movie tickets falls by six units at every price.

(b) The city eliminates a tax that it placed on all local entertainment businesses. The result is that the quantity supplied of movies at any given price increases by 10%.

A low-income country decides to set a price ceiling on bread so it can make sure that bread is affordable to the poor. Table 3.11 provides the conditions of demand and supply. What are the equilibrium price and equilibrium quantity before the price ceiling? What will be the excess demand or the shortage (that is, quantity demanded minus quantity supplied) be if the price ceiling is set at \(2.40? At \)2.00? At \(3.60?
