Introduction (economic efficiency) Allocative efficiency (AE) Productive efficiency (PE) PPC
—relates to how well an economy uses —firms produce a combination of g&s —[diagram] economy produces at the —both types of economic efficiencies

Assumptions of the PPC model Diagram Diagram analysis (within the PPC) Diagram analysis (on the PPC)
—model is constructed based on —economy that is producing within its PPC (x) —economy said to be PE when
several assumptions: is not fully utilising all available resources production moves to a point on the PPC
——closed economy —level of output could have been greater if all (y); all resources used efficiently
——only two types of goods are available resources/FOP are employed and not —AE (Pareto E) achieved when an
left idle
produced —country that is operating within its PPC is
individual cannot be made better off
——factors of production not equally wasteful, not PE without another individual being made
productive —combination of output at (x) is also not AE; worse off
——limited resources not producing all the possible combinations of —on the PPC, a movement signifies
——constant state of technology goods most wanted by consumers more consumption of one good and less
of another
Conclusion
—economy which moves from a point
within its PPC to a point on its PPC is
considered to be engaging in both PE
and AE
—improvement in consumer welfare;
they can now enjoy the greatest
amount of goods that they want at
minimal cost
