Pareto efficiency
(noun)
The state in which no one can be made better off by making another worse off.
Examples of Pareto efficiency in the following topics:
-
Definition of Perfect Competition
- Perfect competition is a market structure that leads to the Pareto-efficient allocation of economic resources.
- Perfect competition leads to the Pareto-efficient allocation of economic resources.
-
Trade Leads to Gains
- An allocation of resources is Pareto efficient when it is impossible to make any one individual better off without making at least one individual worse off.
- A distribution in which Individual A has all of the peanut butter and individual B has all of the jelly is not Pareto efficient, because both parties would be better off if they shared their resources.
- Similarly, an action that makes at least one party better off without making any individual worse off is called a Pareto improvement.
- It is commonly assumed that outcomes that are not Pareto efficient are to be avoided, and if a Pareto improvement is possible it should always be implemented.
- One way to look at whether a transaction is a Pareto improvement is to ask whether it increases consumer or producer surplus without decreasing either party's surplus.
-
Criteria to evaluate alternatives
- Pareto efficiency is the condition where there are no alternatives that will increase the welfare (utility) of one person without reducing the welfare (utility) of any other person(s).
- Pareto efficiency is a restrictive criteria and tends to promote the status quo.
- The Pareto efficiency criterion fails to justify choices that result in the highest valued use of resources (economic efficiency).
- To remedy this problem the criterion of Pareto Potential is used.
- In an ideal world, informed individuals engaged in voluntary exchanges will result in transfers of property rights that are Pareto improvements and lead to economic efficiency.
-
Impacts of Price Changes on Consumer Surplus
- It is important to note that any shift from the good's pareto optimal price will result in a decrease in the total economic surplus.
- A binding price ceiling is one that is lower than the pareto efficient market price.
- This shortage will create a deadweight loss, or a market wide loss of efficiency and value that neither producer nor consumers obtain.
- Explain how shifting a price away from pareto optimal will impact consumer surplus
-
Markets are Typically Efficient
- A perfectly competitive market with full property rights is typically efficient.
- In absolute terms, a situation can be called economically efficient if:
- No one can be made better off without making someone else worse off (commonly referred to as Pareto efficiency),
- Economists refer to two types of market efficiency.
- A market can be perfectly efficient but highly unequal, for example.
-
Understanding and Finding the Deadweight Loss
- In economics, deadweight loss is a loss of economic efficiency that occurs when equilibrium for a good or service is not Pareto optimal.
- In economics, deadweight loss is a loss of economic efficiency that occurs when equilibrium for a good or service is not Pareto optimal.
- When a good or service is not Pareto optimal, the economic efficiency is not at equilibrium.
-
Introduction to Deadweight Loss
- Deadweight loss is the decrease in economic efficiency that occurs when a good or service is not priced at its pareto optimal level.
- Deadweight loss is the decrease in economic efficiency that occurs when a good or service is not priced and produced at its pareto optimal level.
- In a perfectly competitive market, products are priced at the pareto optimal point.
- the point on the supply curve where the y-coordinate equals the non-pareto optimal price;
- the point on the demand curve where the y-coordinate equals the non-pareto optimal price.

How Taxes Impact Efficiency: Deadweight Losses
- In economics, deadweight loss is a loss of economic efficiency that can occur when equilibrium for a good or service is not Pareto optimal.
- In economics, a deadweight loss (also known as excess burden or allocative inefficiency) is a loss of economic efficiency that can occur when equilibrium for a good or service is not Pareto optimal (resource allocation where it is impossible to make any one individual better off without making at least one individual worse off).
- It represents lost efficiency.
-
Voluntary Exchange
- One of the basic concepts described in Chapter I Introduction was "Pareto Efficiency or Pareto Optimality."
- To review, remember that a Pareto efficient or optimal solution to the allocation problem exists when all the alternatives that will improve the welfare (utility) of a least one person, without making anyone else "worse off" have be exhausted.
- This improvement is called a Pareto improvement and the result is said to be Pareto superior to the initial alternative.

Total Quality Management Techniques
- Six sigma, JIT, Pareto analysis, and the Five Whys technique are all approaches that can be used to improve overall quality.
- JIT focuses on continuous improvement to maximize an organization's return on investment, quality, and efficiency.
- Pareto analysis is a statistical technique used to select a limited number of tasks that produce significant overall effect.
- It uses the Pareto principle: most problems have a few key causes.
- Pareto analysis also concludes that 80% of the result can be generated by focusing on 20% of the key work.
