PPF?
shows the maximum possible output combinations of two goods in an economy, assuming full and efficient employment of resources
POINTS ON PPC:
-Any point on the PPC = FoP are fully employed- Within the ppc = economy operating inefficiently with unused resources
What causes outward shift in PPC
increase in quantity and quality of FoP
Factors causing an outward shift of PPC
1) Technological improvements2) Discovery of new resources3) Improvements in education + training
Factors causing an inward shift of PPC
1) Natural Disasters2) Global warming / climate change3) Prolonged recession (workers lose skills)
Productive Efficiency?
when maximum output is produced from the available FoP and when it is not possible to produce more of one good or service without producing less of another
Allocative Efficiency?
when an economy’s FoP are used to produce goods and services that maximise society’s welfare-PPC doesn’t specify an allocatively efficient point
