Pareto efficiency, or Pareto optimality, is an economic state where resources cannot  be reallocated to make one individual better off without making at least one  individual worse off. Pareto efficiency implies that resources are allocated in the  most economically efficient manner, but does not imply equality or fairness. An  economy is said to be in a Pareto optimum state when no economic changes can  make one individual better off without making at least one other individual worse  off. To simplify analysis and discussion the model for general equilibrium uses the two  person, two goods and two resources (or 2 X 2 X 2 model). The investigation is done  in three steps: • Consumption efficiency  • Production efficiency • A combination of Consumption and Production efficiencies.

Question

Pareto efficiency, or Pareto optimality, is an economic state where resources cannot 
be reallocated to make one individual better off without making at least one 
individual worse off. Pareto efficiency implies that resources are allocated in the 
most economically efficient manner, but does not imply equality or fairness. An 
economy is said to be in a Pareto optimum state when no economic changes can 
make one individual better off without making at least one other individual worse 
off.
To simplify analysis and discussion the model for general equilibrium uses the two 
person, two goods and two resources (or 2 X 2 X 2 model). The investigation is done 
in three steps:
• Consumption efficiency 
• Production efficiency
• A combination of Consumption and Production efficiencies.

 


Critically analyze the concept of Pareto efficiency. Use relevant theory and diagrams to 
support your analysis.
