Productive Efficiency: Making Stuff Right Productive efficiency

occurs when a firm produces at the lowest possible cost per unit.

Competition ensures that firms produce at the lowest possible cost per unit.


Allocative Efficiency: Making the Right Stuff Allocative efficiency

occurs when firms produce the output that is most valued by consumers.

Competition among sellers encourage producers to supply more of what consumers value the most.


Distinguish between allocative efficiency and productive efficiency.

Checkpoint: pg. 180

Productive efficiency occurs when the firm produces at the lowest possible cost per unit.

Allocative efficiency occurs when firms produce the output that is most valued by consumers.


Disequilibrium

Disequilibrium—a mismatch between quantity demanded and quantity supplied as the market seeks equilibrium

Disequilibrium is usually a temporary condition when the plans of buyers do not match the plans of sellers.


Other Sources of Disequilibrium Government intervention in the market

Sometimes, as a result of government intervention in markets, disequilibrium can last a while.

Sometimes the market takes a while to adjust New products Sudden change in demand or supply


Disequilibrium A price floor is a minimum selling price

that is above the equilibrium price. To have an impact, a price floor must

be set above the equilibrium price. The Minimum wage is a price floor in the

market for labor. The government sets the minimum labor price

and no one is allowed to pay less.


Price Floor

If a price floor is established above the equilibrium price, a permanent surplus results.


Price Floor

A price floor established at or below the equilibrium price has no effect.


Disequilibrium

A price ceiling is a maximum selling price that is below the equilibrium.

To have an impact, a price ceiling must be set below the equilibrium price. The good intensions of government

officials create shortages and surpluses that often are economically wasteful.


Price Ceiling

A price ceiling is established below the equilibrium price, a permanent shortage will result.


Price Ceiling

A price ceiling is established at or above the equilibrium price, has no effect.


What happens when governments impose price floors and price ceilings?

When governments impose price floors or ceilings: market prices are distorted and interfere with

the market’s ability to allocate resources efficiently.

This results in disequilibrium of the market.

Checkpoint: pg. 181


Consumer Surplus

Consumer surplus - is the difference between the total amount consumers would have been willing and able to pay for that quantity and the total amount they actually do pay.


An Application of Consumer Surplus: Free Medical Care Certain Americans are

provided government-subsidized medical care.

When something is provided for free, people consume it until their marginal benefit is zero.


How do consumers benefit from market exchange?

Consumers benefit from market exchange by receiving the goods they demand and want at a price they are willing to pay.

When there is a consumer surplus, consumers pay lower prices than they would have originally been willing to pay.
